[Nagios-users] using check_snmp_ifstatus.pl plugin for windows servers

[Dhaval Thakar]

hi,

i am using check_snmp_ifstatus.pl downloaded from
http://shawnflynn.com/2008/08/13/nagios-plugincheck_snmp_ifstatuspl/

this is very good tool to monitor interface utilization.
i want to use it in the replacement of mrtg.

this works fine for the linux systems (as in interface i need to mention
only eth0/eth1)

whereas i am unable to configure this tool to check windows interface

i am getting proper result for linux based server
snmpwalk -v 2c -c public 172.20.20.4 ifDescr
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0
IF-MIB::ifDescr.3 = STRING: eth1
IF-MIB::ifDescr.4 = STRING: sit0

./check_snmp_ifstatus.pl -H 172.20.20.4 -C public -i eth0
OK: eth0 is UP at 1Gbps. RX=56.87Kbps (0%), TX=443Kbps

for windows based server

RTL8139/810x Family Fast Ethernet NIC"
CRITICAL: Could not match Realtek RTL8139/810x Family Fast Ethernet NIC

kindly guide me the proper way to utilize this plugin for windows based
servers.

Re: [Nagios-users] Initial problems

[Taylor Dondich]

First off, the Nagios output states it is Nagios 3.0.1, not Nagios
2.x.  This is fine, just refer to the Nagios 3 documentation as some
things have changed, such as the first couple of warnings.

First off, it looks like you have a permissions issue on the
/usr/local/nagios/log directory.  Make sure the directory exists, and
it's contents are writable by the Nagios user.

Second, the fatal error states that the object property in
minimal.cfg, line 60 is invalid.  It may be a directive that is no
longer allowed in Nagios 3 or has been renamed (it has a habit of
doing that).  The book you described is great to understand the basics
of Nagios, but try to be aware there are differences and you should
verify it by looking at the Nagios 3 docs at
http://nagios.sourceforge.net/docs/3_0/

[Nagios-users] Initial problems

[scott]

Greetings

   I am just starting to use nagios and it looks promising.  Along with 
the documentation supplied, I am also using the text from the book Pro 
Nagios 2.0 by James Turnbull. 

   The version of nagios is 2.0 February 06, 2006 as this came with the 
SuSE Linux 11.0.

   Tried starting nagious and get these messages in the start:
nagios /usr/local/nagios/etc/nagios.cfg

   Suggestions on how to resolve these errors would be appreciated.

Re: [Nagios-users] ndoutils Query optimisation

[Simon Finch]

Hi Alan,
 
Up to yesterday I had a similar problem with our NDO db on the same spec box as 
yours.
 
Are your tables primarily type innodb like mine ?
I am asking as my NDO db was created by Centreon's install script and not the 
normal way, if so then the following may help.
Your initial post showed no setting for innodb_buffer_pool_size if you are 
using lots of innodb tables then this needs to be as big as you can afford.
Second is innodb_flush_log_at_trx_commit which defaults to 1, which is safe, 
but slow, it commits after every transaction.
 
I have 9 Nagios servers feeding data from 2500 hosts into 1 NDO db, when I 
started Mysql was reported by top as using 300 - 350% of cpu and the whole 
system was virtually unusable, now cpu usage is 10 - 50% with occasional peaks 
of 90% and all is good.
 
These are the settings I am using:
 
key_buffer_size=64M
thread_cache_size=32
innodb_buffer_pool_size=512M
innodb_flush_log_at_trx_commit=0
innodb_log_file_size=32M
read_buffer_size=256k
tmp_table_size=64M
join_buffer_size=8M
query_cache_size=32M
table_cache=1024
I am still fiddling with settings, but these seem good for now. I am not a dba, 
only a sysadmin who had to make it work. Hopefully I can help others with 
similar problems.
 
Thanks and regards,

[Nagios-users] external command to enable all active service checks

[Robert Anderson]

I am setting up a failover nagios instance as described here.

http://nagios.sourceforge.net/docs/3_0/redundancy.html#scenario_2

I have looked through the external commands but cannot find one that will
enable or disable all active service checks. Am I missing something? I have
found external command that apply to a single service, servicegroup or host,
but none that apply to all services. Please help.

Thanks,

I had a similar issue. I tried excluding a time slot between 0300, and
0600 due to large DB loads causing website performance issues
(backups, indexing, and such).  When the start of the exception rolled
around, nagios would just stop checking that service, and would only
restart on a forced manual check, or restart of the nagios service.  I
ended up changing the theory to continue checking 24x7, but only alert
when outside the exception.  Not that it helps the issue, but it
stopped the symptoms.  I never got around to really digging into the
issue any deeper.  It did give me the added benefit of knowing when
the server was actually down during the maintenance window, and when
it was just being slow.  This was handy for management purposes so
they could calculate if they need more head count.

The permissions on your mail queue directory for your mailer are  
probably more open on the boxen that work.

The alternative is to add the nagios user to a group that has read  
permissions to your mail queue or generally more open permissions for  
all users on the mail queue in general. The former may be comparable  
to the sudo approach and the latter is definitely less secure than  
either.

I'm not sure if this applies to your system or not, but you might be  
able to get away with just adding the 'nagios' user to the correct  
group to be able to read the mail spool directory, possibly /var/spool/ 
mqueue.  Again, not sure if it'll work on your system, but it's  
something to check.

Re: [Nagios-users] nrpe and check_mailq

[Kevin Freels]

Okay, I started to go down the sudo path until I realized I have other
systems that check_mailq works just fine on without having to be root.
The difference is that the system it works on is a FreeBSD and the
system  that's choking is Linux.

check_mailq on the working system is running as the same user ('nagios')
as the Linux box, so neither of them are root. The perms/owners for
check_mailq are the same for both systems.

*AND* I can run check_mailq on the FreeBSD box as a mortal user (me),
but not on the Linux box. I did notice that version of Perl on the Linux
box is 5.8.0, while the working FreeBSD is 5.005. Perl on the FreeBSD is
also chgrp'd to wheel, not root.

Maybe somewhere in there lies the culprit?

I'm also not comfortable adding a generic user ('nagios') to sudo. I
realize I can restrict the commands the user can use, but still

BTW, thanks for the replies

My guess would be that your webbrowser is converting the character.

Which webbrowsers have you tried?

Re: [Nagios-users] checks, notifications don't work after time period exception

[Seth Simmons]

The system date is correct and Nagios is showing the correct day and
time on the status page.  If I stop Nagios, I don't see any other Nagios
processes running.  The two templates here have not been touched.  I
looked at both and have 24x7 for all times which is the default.  I just
modified the time definitions as you have it listed and I'll see what
happens tonight.  There are also no custom time settings in nagios.cfg;
all the settings related to time zone, etc are commented out.

When I start dealing with time problems with Nagios I have a small  
list that I try first just to it out.
* Check date/time of monitoring server and that it is the right  
timezone (UTC or whatever you want it as).
* Check that the Nagios web interface is displaying the time you  
expect it to (top left corner in most cgis).  In the nagios.cfg you  
may have set additional time information in there.
* Stop the nagios process, checking that there are are no other  
running instances left.  'service nagios stop' 'ps aux |grep nagios'
* Restart the nagios process.

Sometimes you can get duplicate Nagios daemons running and they can  
cause many odd problems like this.  Also I hope we are not dealing  
with any time translations with the "overseas" group.

So you are saying that "Server-A" is supposed to be checked in the  
timerange 24x7 minus 4:00am-5:30am each day, but when it stops at  
4:00am it will not start checking until the next day, unless you force  
it through an external command to start checking again?  It is  
possible that there could be a bug, but you seem to have a really  
common timeperiod definition type.  I normally suggest that users  
always run the checks 24x7 and then just modify the notification  
periods (like you did with 'Server-B).  But I would try it with a  
simple time definition first.

# Test timeperiod for the recycle service.
define timeperiod{
 timeperiod_name recycle
 alias   recycle
 sunday  00:00-04:00,05:30-24:00
 monday  00:00-04:00,05:30-24:00
 tuesday 00:00-04:00,05:30-24:00
 wednesday   00:00-04:00,05:30-24:00
 thursday00:00-04:00,05:30-24:00
 friday  00:00-04:00,05:30-24:00
 saturday00:00-04:00,05:30-24:00
 }


Also what does your "generic-service" and "local-service" templates  
look like?  There could be some settings that are following you  
through those templates.  Also you may have modified some settings in  
the nagios.cfg that makes changes to how nagios deals with time.

The difference between those are that they are using a different  
service template.  Server-B is using 'local-service'.

huh?
Why not?
I'we always thought of NRPE to be vastly superior to the NSClient 
protocol myself...

This is how I would have wrote the timeperiod definitions to make them  
more clear.  I've used the exclude method many times so I am sure that  
it works as you are expecting.

define timeperiod{
 timeperiod_name 24x7
 alias   24 Hours A Day, 7

NRPE? To check a Windows-Box? No, that's not really funny...

I found out, how it works:Windows Services always have 2 names, the internal
one is better, than the description-name.

[Nagios-users] checks, notifications don't work after time period exception

[Seth Simmons]

We have a qa group overseas that will work on our customer sites during
the US overnight.  To avoid false alerts, I added a time exception so
notifications are not sent out between 4am and 5:30am.  The problem is,
after the exception, Nagios (3.0.3) won't send notifications, neither
are checks performed for any sites with an exception.  If a site is in a
critical state either shortly after 4 or (if they start early) right
before 4, checks do not continue after 5:30.  When I look at Nagios
later, it shows it in critical and the last check was done at 3:58am
with the next check at midnight the next day.

 

Let me give some more specific examples:

Server-A is running abc.customer.com for us and our qa group takes the
site down at 3:55am, before the 4am exception.  Nagios will show as
critical until either midnight the next day, or you force a check on the
service.  So, say at 8am I look at it, the service is critical with last
check at 3:55am and next scheduled check at 12am tomorrow.  When I force
a check, it will continue on normal check schedule and send notice that
the service is ok.

 

Server-B is also running a site and tomcat is stopped at 4:10am.  This
service has notification period with the same time period with
exceptions from 4am - 5:30am.  After that it will not send
notifications.  At 8am it is still doing checks and saying is critical,
but when looking at the details it says it has not sent any
notifications.  When I force a check it still won't do it.  If I restart
Nagios then it does a check it will send first notice.  I don't see
anything wrong with my time period so not sure where the issue is.  Not
sure if anyone else has noticed this before.

 

Here is what I have for that time period and checks for the above
examples:

 

define timeperiod{

timeperiod_name   url-monitor

alias   url-monitor

sunday 00:00-23:59

monday   00:00-23:59

[Nagios-users] Checking Windows Services with stupid names.

[Klaus Umbach]

Hi,

I have a service on a windows-box to check, which has a "&" in the name.
(With check_nt and nsclient++)

with 'SERVICESTATE -l "Foo & Bar"' it checks for the services 'foo' and
'bar' , \&, \\\& and using ' instead of " did'n't help.

How do I check this?

Cheers
Klaus

I'm not surprised. Openntpd is designed to be a much more lightweight
version than bog-standard ntpd. Primarily to not have to haul around
refclock support to each and every installation.

If it's any relief though, ntpq *will* work on all stratum1 servers,
as only vanilla ntpd has refclock support.
