Thierry,

Be aware that you are moving very fast to the "annoying type of poster"
that is getting ignored in full. I do not think you want to go there.

It seems you have a hard time finding information on your own but
overwelm the mailinglist with questions that do not show the commitment
to take any actions on your own.

Please read the instruction on asking question on mailinglists the smart
way unless it is your intention to be ignored:
http://www.catb.org/%7Eesr/faqs/smart-questions.html

It might also help to see that someone posted their public key to the
public key servers if they insist on signing their messages.

At this point I think some of us might want to be convinced we are not
asked to do your homework but you are in fact a bonafide nagios user and
not a student who is incapable to complete a simple assignment.

It's not that we do not want to help someone but with Nagios it is
mandatory to read the manual at least once cover to cover. Then you
should have seen at least everything and you should be able to ask
specific questions.

I think you are currently unaware of the impression that you leave on
the mailinglist of yourself and how it will impact the way people will
respond to you.

Hugo.

On the main page, on the left, there is a link called downloads. Sources
are there.

Notification_options are probably setup either in your nagios
configuration's service template file , or within the service definition
itself. 


These files are usually located in /usr/local/nagios/etc, or
/usr/local/nagios/etc/objects (3.x)

i.e this service definition monitors for the windows service named
"VMWare converter service" - see notification_options. (or just skip
pulling out your hair and rtfm?) ;)


define service{
use generic-service ; Name
of service template to use
host_name   srv099

max_check_attempts  5

I would suspect multiple nagios daemons running at the same time in a  
case like this. The other symptoms sound consistent with that.

Something has exceeded your warning threshold but not your critical  
threshold. That's all we can say based on the information you've  
given. Please post the service{} and command{} definitions as well as  
the plugin output if you need further help.

> More, i don't receive a mail nofitication

Is it configured correctly (i.e. rtfm)? There's much documentation on  
Notifications.

You tell us. That'll help us answer your questions. Posting relevent  
configuration snippets, nagios version, OS, etc is very helpful too.

First of all please do not cross-post. Many people read both lists
anyways, so cross-posting just pollute their inbox.

The time in the web interface it the time of the server. Make sure to
regularly sync the server time or run a properly configured local ntp
daemon to keep time sync.

The issue about having all service ok, than all red is very strange...
Are you sure you don't have an IP conflict on that your old & new
servers, or a DNS record returning the IP of both servers?

The NRPE socket timeout after 10 seconds could be the conlfiguration on
the clients - since there's no authentication in NRPE it could be that
they're only accepting connections from the old server.

Check your "notification options" . if the page is password protected,
you can change it from
notification_options  w,u,c,r

To 

Notification_options u,c,r 

(this gets rid of notifications on warnings only such as access denied
etc).

It does exist and I pasted the text from it in a previous e-mail earlier
today.  I downloaded it from nagiosexchange as an add-on so no default
Nagios install would have this.  It is located
in /usr/local/nagios/libexec.  See below:

[EMAIL PROTECTED]:/usr/local/nagios/libexec# locate send_mail.pl
/home/zlocaladmin/Documents/send_mail.pl
/usr/local/nagios/libexec/send_mail.pl
[EMAIL PROTECTED]:/usr/local/nagios/libexec# 

The /home/zlocaladmin/Documents/send_mail.pl reference is where the file
was downloaded and I copied rather than moved it into
the /usr/local/nagios/libexec folder so that one is not being used.  I
have looked this over and over and can't figure out why it says it does
not exist.  It's there.

[Nagios-users] Re-Notification

[Wade Peacock]

I have been using Nagios since the days of Netsaint. I have never had this 
issue. I have a service that is continuously re-notifying.
It should be notify once. I have reviewed my configuration file. I can not 
figure it out.

Here is the service specific information:

define service {
nametemp
is_volatile 0
check_period24x7
max_check_attempts  1
normal_check_interval   5
retry_check_interval2
active_checks_enabled   1
passive_checks_enabled  1
parallelize_check   1
obsess_over_service 0
check_freshness 0
notifications_enabled   1
notification_interval   0
notification_period 24x7
notification_optionsc,r
event_handler_enabled   1
flap_detection_enabled  1
process_perf_data   1
retain_status_information   1
retain_nonstatus_information1
contact_groups  Test
}

define service {
service_description Temperature - CABLE HEADEND
use temp
host_name   Sensatronics E4
check_command   check_temperature!2
}

I have tried Version 3.0rc2, 3.0.1, 3.0.2 & 3.0.3

Thanks for your help.

I have yet to see you confirm that send_mail.pl actually exists.  None 
of my default installs have this script, so I'm assuming that's your 
problem. 

Download it from NagiosExchange 
(http://www.nagiosexchange.org/cgi-bin/page.cgi?g=2217.html;d=1) and put 
it wherever $USER1$ is (this is the default location of check_x 
commands, it's defined in Nagios' resources file).

You should no problem if you are running on decent hardware since  
don't have that many hosts and only a few services will be checked  
with SSH.  NRPE is definitely the preferred method for running remote  
checks.  With each SSH check you are creating a new tunnel, logging  
onto a remote machine as the user you setup, running the command,  
waiting for output, and closing the connection.  Plus you are normally  
creating a public ssh key that allows for password-less log on.  You  
can see where there are both performance and security concerns.

Check_by_ssh will work fine but I would at least take a took at NRPE.   
The difference in setting it up may be smaller than you think since  
you will have to touch each machine to install the plugins no matter  
what you decide.

As Marc broke down the sed line I will break down the line above, the #
character is indeed a comment character, but only to PERL. PERL is not
what tries to load the file initially, the shell tries to load the file
as a compiled program(like /bin/ls is the compiled program that lists
the files in a directory: I ran this on my nagios server as an example):

[EMAIL PROTECTED] nagios]$ file /bin/ls
/bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for
GNU/Linux 2.4.0, dynamically linked (uses shared libs), stripped
[EMAIL PROTECTED] nagios]$

But since a PERL script is interpretted and not compiled (technically
that isn't true either but it might as well be), the loader normally
doesn't know what to do with it, so the gods of UNIX decided that the
characters #! Would have special signifigance to the loader at the
beginning of the file. They indicate the program that will interpret the
script. So when the loader sees it it then looks for the /usr/bin/perl
program and execs it with the -w command and the script path so that it
will interpret the script. If /usr/bin/perl does not exist you will have
problems. To verify the existence of it just "ls /usr/bin/perl". Most
systems have it there, but a few do not, instead they keep it in
/usr/local/bin/ so you might need to change that line to
"#!/usr/local/bin/perl -w" instead. But only if it is in that location,
if it isn't you will need to find it. Which may not be so hard since
nagios probably found it when you installed it and if you do a "file *"
in the plugin directory and then type "head " and the name of a perl
script you should see where it really is.

Hope this he

Bummer.  I made the change and did not get any errors, however I am
still getting the same error in the nagios.log:

[1216757322] Warning: Attempting to execute the command
"/usr/local/nagios/libexec/send_mail.pl -n "SERVICE PROBLEM" -h
"jwilliamspc" -s "CRITICAL" -a "10.10.113.51" -i "PrintSpooler -
Spooler: Stopped - check_nt!SERVICESTATE!-d SHOWALL -l Spooler" -d "Tue
Jul 22 13:08:42 PDT 2008" -e "[EMAIL PROTECTED]"" resulted in
a return code of 126.  Make sure the script or binary you are trying to
execute actually exists.

I am not sure if it is permissions or not.  The user nagios is the owner
of this file and should have access.  I ran this from the command
prompt, but realize the $wildcards$ will have no meaning from here.

[EMAIL PROTECTED]:/usr/local/nagios/libexec# 
/usr/local/nagios/libexec/send_mail.pl -n "HOST $NOTIFICATIONTYPE$" -h 
"$HOSTNAME$"  -s "$HOSTSTATE$" -a "$HOSTADDRESS$" -i "$HOSTOUTPUT$" -d 
"$LONGDATETIME$" -e "$CONTACTEMAIL$"
bash: /usr/local/nagios/libexec/send_mail.pl: Permission denied

-d "$LONGDATETIME$" -e "$CONTACTEMAIL$"
sudo: /usr/local/nagios/libexec/send_mail.pl: command not found

The first attempt was run as logged in user (zlocaladmin) which does not
have rights.  Not sure why it still gave permissions error since I ran
sudo - long before in that session and everything else I can run without
the sudo command.  Anyhow when run with root access I get the command
not found error.  I'm stumped.

[Nagios-users] Issues with timeperiods

[Fulton, David]

I was attempting to setup an on call rotation per the directions on the
website and have run into a little snag that I am not sure really is a
snag. My timeperiods file looks like this:

define timeperiod{
timeperiod_name cbakeroncall
alias   Charles Baker on call weeks
2008-07-21  00:00-24:00
}
# timeperiods.cfg - Config file for Nagios (www.nagios.org)
#
# Written by Nawui 0.1.5-dev. Manually editing this file is a bad idea
since Nawui will
# overwrite it. 
#
# Exported at 11:54:47 - 01 Apr 2004
#


define timeperiod {
timeperiod_name 24x7
alias   24 Hours A Day, 7 Days A Week
sunday  00:00-24:00
monday  00:00-24:00
tuesday 00:00-24:00
wednesday   00:00-24:00
thursday00:00-24:00
friday  00:00-24:00
saturday00:00-24:00
}

define timeperiod {

tuesday 08:00-18:00
wednesday   08:00-18:00
thursday08:00-18:00
friday  08:00-18:00
}

define timeperiod {
timeperiod_name nonworkhours
alias   Non-Work Hours
sunday  00:00-24:00
monday  00:00-09:00,17:00-24:00

friday  00:00-09:00,17:00-24:00
saturday00:00-24:00
}

define timeperiod {
timeperiod_name none
alias   No Time Is A Good Time
}

# This says some guy named Nawui is gonna overwrite this file if I put
this here.
# Well, I'm just that crazy.
define timeperiod {
timeperiod_name non_netapp_maintenance
alias   Always except NetApp Maintenance cronjobs
sunday  00:00-01:00,05:00-24:00
monday  00:00-01:00,05:00-24:00
tuesday 00:00-01:00,05:00-24:00
wednesday   00:00-01:00,05:00-24:00

friday  00:00-01:00,05:00-24:00
saturday00:00-01:00,05:00-24:00
}

Now, the problem is at the top of the file, if I look at the timeperiods
config in the CGI it looks like this:

Time Periods

friday  08:00:00 - 18:00:00 

Notice the date in the config file is 2008-07-21 and the date the CGI
reports is 2008-05-21. So my question is this, is this just a matter of
the CGI being broken and not being able to correctly interpret the
configuration, or is it nagios itself that is broken. If it is just the
CGI I will be perfectly okay with that. If not, I would like to put it
in as a bug.

Thanks

Correction. It should have been send_mail.pl, not check_sendmail.pl.

Thank you for that breakdown.  

I am still having the same error in my nagios.log:

"[1216749581] SERVICE NOTIFICATION:
nagiosadmin;jwilliamspc;PrintSpooler;OK;service-notify-by-email;Spooler:
Started
[1216749581] Warning: Attempting to execute the command

10:59:41 PDT 2008" -e "[EMAIL PROTECTED]"" resulted in a
return code of 126.  Make sure the script or binary you are trying to
execute actually exists..."

The top line in the send_mail.pl script is indeed "#!/usr/bin/perl -w".
I am not sure what it does though.  Doesn't the # mean it is remarked?
I guess my confusion is that there is no such file on my system called
check_sendmail.pl or check_mail.pl.  I was unable to locate any of them.
There is only a check_mailq.  That is why when you state:

#!/usr/bin/perl -w : what the previous match will be replaced with

I get lost.

Ok. sed 101.

sed -i '1s,.*,#!/usr/bin/perl -w,' check_sendmail.pl

The above is a sed 1-liner. It performs an immediate action and then  
exits. What action? Let's break it down --

sed : this is the command to be executed
-i : this tells sed that it's going to be editing an existing file
1s : the start of the actual sed script. This means we're going to be  
doing 1 substitution
.* : this is what we're going to be looking for, essentially any  
content on the line
#!/usr/bin/perl -w : what the previous match will be replaced with
check_sendmail.pl : The file that sed is going to be editing

The end result is that sed would replace the entire first line of the  
file check_sendmail.pl, located in your current directory, with the  
text '#!/usr/bin/perl -w'.

Your confusion is that the filename should have been check_mail.pl,  
not check_sendmail.pl.

Hi Brent,

It doesn't have to be a software firewall.  I assume if you're running 
public-facing services, your servers are firewalled in some way, be it 
hardware, software or router-based?  If not then you've got a bigger 
worry than NRPE being compromised.  And if you are, well where's the 
harm in adding another rule to it?

allowed_host does do the job, but it rejects the connection after it 
hits NRPE (i.e. it's rejected from within NRPE.)  The firewall adds an 
extra layer of security, and prevents connection attempts from even 
reaching NRPE.  I don't believe NRPE is by default tcpwrapped, see here: 
http://www.nagios.org/faqs/viewfaq.php?faq_id=101.

Regards,

Andy

This is incorrect. It should be 'perl', not 'pearl'. That's what  
they've been trying to get you to correct. Edit the file and fix it.

I am guessing (with all my vast linux experience...that's sarcasm) that
perhaps the send_mail.pl wrapper does not know how to find the actual
senmail file which is located in /usr/lib.  I don't see anything in the
send_mail.pl script that indicates it is looking for it though.  Here is
the send_mail.pl file contents:

I ran that command and got nothing.  No response.  See below:

[EMAIL PROTECTED]:/usr/local/nagios/libexec# locate check_sendmail.pl
[EMAIL PROTECTED]:/usr/local/nagios/libexec# 

The libexec directory does have the send_mail.pl file (not sendmail.pl).

Are you in the correct directory?

Try running the following:

locate check_sendmail.pl

then cd to the directory that it gives you and run the sed command
provided earlier.

It was about time I changed the subject line of my e-mail since the
NSClient++ service restart issue is fixed thanks to you guys.  I am
reposting this since my last e-mail on Friday which is at the bottom of
this thread.  I was hoping to verify the syntax of this command:

 

sed -i '1s,.*,#!/usr/bin/perl -w,' check_sendmail.pl

 

It returns this:

 

sed: can't read check_sendmail.pl: No such file or directory

I'm guessing the output was actually
#! /usr/local/bin/perl -w
which is quite different from what you wrote, but I'll have to
assume that the output you gave me is actually correct (who in
their right minds would give false info to someone who's trying
to help them??), so here it goes:

* There's your error right there. To begin with, you probably
don't
have a binary named "pearl" anywhere on your system.
* There's "#!" in front of the name of the script interpreter,
so
the kernel has no idea what to do with it.

Run this command and it'll magically start working:

sed -i '1s,.*,#!/usr/bin/perl -w,' check_sendmail.pl

Note that "similar" hardly ever cuts it, especially if you want
more help and don't paste the "similar" command you actually
used along with the output it produced. copy-paste is your
friend.

Got it...as far as the top posting goes...makes sense.  Thanks.
And yes
there was a #! In front as you said.  I did say similar just
because the
OP who was helping me said I would get something similar to
#!/usr/bin/perl .  My output was similar to that,
but not
exact.  Thanks for the response. I ran the following:


sed -i '1s,.*,#!/usr/bin/perl -w,' check_sendmail.pl

return:

sed: can't read check_sendmail.pl: No such file or directory


 

I been following  your Emails on this issue and it looks like this must
be some simple mistake somewhere, for example runtime Libexec is not the
directory your using, FIlemames mispellings, things missing from the
path or some other unkown issue.

 

Try running some normal shell script that just gives a date or pwd to
validate the Libexec directory you are copying files to is the one
nagios is run from.

 

In the above command was it suppose to be sendmail.pl instead of
check_sendmail.pl ? (I am not sure I did not think hard about what the
command does) but most of the prior emails mentioned only sendmail.pl
while check_ is common prefix of most common nagios plugins.

 

Last in prior posts I noticed the -n in the command has a space between
the - and the n is it really there or is it just my email reader? if it
is there should it be there?

 

Tony (Author of NC_net)

(I actually prefer reading Top posted msg - but I understand Andreas
point on Bottom posting or inline posting)

 

 

Good question Tony.  There is no such file called check_sendmail on my
system.  Other scripts are running fine out of
/usr/local/nagios/libexec.  I am not sure if perhaps the send_mail.pl
script is perhaps looking for the pearl binary in the wrong folder
/usr/bin/perl as opposed to /usr/local/bin/perl?  I am not at work now
but will dig in later tonight.  I am a victim of my own lack of Linux
experience here I admit, but I'm learning.  I have a feeling if any of
you were looking at everything I have here it would jump out at you.
I'm going to team up with a colleague of mine here who is a good Linux
guy and get his input as well.  

 

As usual thanks again for your time and expertise.

Please post the host Status Information (click on the host in the GUI)  
when this is happening. Verify that you do not have multiple nagios  
daemons running at the same time. Make sure that you do not have  
is_volatile set for the services.

They may be displayed as CRITICAL, and they are, but no alerts are  
sent for them.

Not really. Nagios is primarily a service monitor and services are  
central to it's check logic. If a service reports a non-OK state,  
Nagios will check the status of the host. If the host reports a non-OK  
state, notifications for services are suppressed but will continue to  
be checked. The service checks are necessary because Nagios uses them  
to determine when the host has recovered. Bear in mind that the normal  
and recommended operation of nagios is without regularly scheduled  
active host checks. In such a configuration, a host recovery would  
never be noticed if service checks were disabled.

Nagios automagically suppresses alerts for services on down/ 
unreachable hosts already. No special configuration is necessary other  
than a host check_command that works correctly.

Pending status means that no services on the host have been checked  
yet. No special action necessary there.

Re: [Nagios-users] Temporarily changing thresholds of an NRPE driven service check

[Sean McAfee]

I believe you're right - you'd have to schedule two checks, each using a 
custom time period. 

This can simplified by using the exclude and use directives:

define timeperiod{
timeperiod_name vignette_backup
sunday  20:00-23:00
monday  20:00-23:00
tuesday 20:00-23:00
wednesday   20:00-23:00
thursday20:00-23:00
friday  20:00-23:00
saturday20:00-23:00
}

define timeperiod{
timeperiod_name vignette
use 24x7
exclude vignette_backup
}

The standard check would then have check_period as vignette, while the 
one you'd like to run during your backup window would use vignette_backup.

[Nagios-users] host/service dependencies

[Assaf Flatto]

Hello 

I'm trying to figure out a way or logic of service /host dependency .
In today's dependency logic - there is no correlation between host failure and 
the host services , 
even if the host is down - services are still being checked and reported as 
critical .

there is a need to designate a specific dependency check for services and then 
it will only "learn" 
of the down status .

Is there a way to tell nagios that once a server is down - not to check the 
services assigned to 
this server ? to me it seems like this 

define dependency {
host_name   foo
dependent_service_description *
execution_failure_criteria  d,p,u
notification_failure_criteria   d,u,p
}
So once the host is down/unknown/pending , all the services on the server are 
not checked and do not 
send alerts .

anyone knows on a way to implement it now ? or is such a logic being developed 
for later versions ?

[Nagios-users] Temporarily changing thresholds of an NRPE driven service check

[Jim . Melin]

Good morning.

We have a vignette content management server that every night syncs its content 
to a backup volume for nightly 'snapshot' purposes. This runs about 2
hours. The service check that runs is NRPE driven, and we're using simple NRPE 
config where the ok, warn, critical values are coded on the target
systems nrpe.conf file (we intend to change this when we convert to Nagios 
version 3).

Given this structure is there a good way to be able to tell nagios from 20:00 
to 23:00 use a diff service check? I figure it has to be something to do
with a custom time period, but I'm really not sure what all I would need to do 
to make it work correctly.

Any insights appreciated.

We use Nagios to monitor a number of servers running Xen, and to  
monitor the Xen VMs. There's no question of installing Nagios in each  
VM, just as you don't need to install Nagios on each real server you  
monitor. Instead, you have to install something which can respond to  
Nagios queries on each VM. We choose to run snmpd on each VM but you  
can use other methods too.

If you instead don't want to run anything on the VMs then you'd be  
restricted to running some scripts on the hos which tell you the  
status of the VMs - perhaps somebody already has a plugin to do that.





Kindest regards,



Niall  O Broin

[Nagios-users] Best practice for monitoring virtual machine (OpenVZ)

[howard chen]

Hello,

We have servers hosting virtual machines (around 10-20 per real
server), we are using OpenVZ (a kind of container based VM), we are
very satisfied with the VM performance currently.

Now, we are planning to add monitoring to each VM as well as the host
itself, this come to a problem, because if I install each VM with
their own nagios, seems there will be quite a lot of overheads in
total..

So I want to ask if anyone here is using nagios with VM and can share
about some tricks in deployment?

Thanks.

Re: [Nagios-users] Monitor log file for inactivity?

[Sean Carolan]

I just tested my log file and it updates the time stamp in more or
less real time.  The check_file_age will probably work perfectly for
my needs.  There are in fact instances when logging is still working
but the application is misbehaving, but at least this will take care
of those times when it is completely stuck and not logging at all.

I have heard that check_by_ssh can cause a lot of overhead on large
networks where there are many checks going on at the same time.  Can
anyone give some practical numbers here?  I have about 160 machines
that need to be monitored, most of them will simply have the basic
CPU/Disk/Memory monitoring.  I would think that on a small network
like this it should not be a major problem.

Nice.  I really appreciate the help.  Nagios will soon be replacing
the feature-challenged monitoring software we are using now for Linux
machines.

I believe check_procs will do what you're looking for.

Im sure we the same, in that we run very minimalistic (kernel tweaking 
too) software installation / services (namely just http, ssh). But now I 
have to go write a ruleset all for blocking a port. I was hoping that 
the "allowed_host" (which from what I read is tcpwrapped), was good enough.

Or am I missing something.

Thanks

Hi,

We run NRPE on 4 public-facing servers.  All unnecessary ports are  
blocked by a firewall, port 5666 is limited to our Nagios server only,  
and NRPE is configured (through its config file) to only accept  
connections from our Nagios server.

Never had any issues.

We run it on some public-facing IP Addresses, however we use a firewall
such as shorewall to limit connections to port 5666 to only certain IP
addresses.

It's basically a firewall rule that states:

DROP EVERYTHING 
UNLESS:
IP ADDRESS IS AN AUTHORISED IP

Hope this helps,

[Nagios-users] check cpu - python process

[Tom Brown]

Hi

We have a, badly written, app that runs python and it regularly pins 1 
core to 100% cpu utilization. The utilization may drop for a short 
period but then get pinned again.  Is there any check out there that can 
check for a process consuming 100% of a core, even if overall CPU load 
is low eg in an 8 core box, and alert against that?

Hi,

I've got a strange problem with the nagios. Recently, for testing 
purpose we did install nagios server on a intel based pc and now we 
would like to move the nagios server to an high end machine like HP 
proliant DL 380.


The nagios server on Intel based pc works fine and it was able to 
monitor all the clients using check_nrpe plugin. I have now installed 
nagios server, nagios plugins and nrpe on a high end machine and 
copied all the configuration files from old server to here and then 
started nagios service. All looks ok except for scheduling checks.


The time on nagios server is ahead of the time displayed on the nagios 
interface for Next Scheduled Check. The Next Scheduled Check for some 
service shows,


Next Scheduled Check:  07-22-2008 09:31:04
Last Check Time:07-22-2008 09:37:53

but the time on nagios server is,
Tue Jul 22 09:40:06 GMT 2008

The time is not sync properly and when I refresh the page maually, it 
shows all services are in green which means all are working ok. but 
after few seconds when I refresh the same page manually, the services 
were in red color. tells me the error as , critical CHECK_NRPE: Socket 
timeout after 10 seconds


then if you refresh later some point, all service will show in green. 
why does this difference?


where do i change the settings so the time on the nagios interface 
will sync the time with the nagios server?


please help me!!!

Thanks

Hi,
you should be sure that all your servers(nagios server and the ones 
being checked) run the same time, for example by using a ntp server to 
synchronise your time. That will avoid any problems like different time 
in checks

Nagios reads the time on the server, is your server getting time from an ntp
server?

[Nagios-users] schedule check problem

[asam30]

Hi,

I've got a strange problem with the nagios. Recently, for testing purpose we
did install nagios server on a intel based pc and now we would like to move
the nagios server to an high end machine like HP proliant DL 380.

The nagios server on Intel based pc works fine and it was able to monitor
all the clients using check_nrpe plugin. I have now installed nagios server,
nagios plugins and nrpe on a high end machine and copied all the
configuration files from old server to here and then started nagios service.
All looks ok except for scheduling checks.

The time on nagios server is ahead of the time displayed on the nagios
interface for Next Scheduled Check. The Next Scheduled Check for some
service shows,

Next Scheduled Check:  07-22-2008 09:31:04
Last Check Time:07-22-2008 09:37:53

but the time on nagios server is,
Tue Jul 22 09:40:06 GMT 2008

all services are in green which means all are working ok. but after few
seconds when I refresh the same page manually, the services were in red
color. tells me the error as , critical CHECK_NRPE: Socket timeout after 10
seconds

then if you refresh later some point, all service will show in green. why
does this difference?

where do i change the settings so the time on the nagios interface will sync
the time with the nagios server?

please help me!!!
