Re: [Nagios-users] Question regarding Availability Report

[Javier Garces Asensio]

¿Perhaps a timeout in the web server because the archive logs are too long
and the avail.cgi script needs a lot of time to process them?
Good luck

Asunto: [Nagios-users] Question regarding Availability Report

Hi,

we run Nagios for a some years now and only from time to time I had to
generate Host Availability Reports.

Now that I updated to the latest 3.4.4 (we hat 3.4.1 installed) I wanted to
generate some reports for host availability in 2012.

So I select the host, set "Report Period:" to "Last Year" and leave the
other options untouched.

Hitting the create report button fires up the avail.cgi on the nagios system
ad it is doing some work with up to 99% of CPU.

But after some time, the command is ended the webpage is still empty. No
report. No error or anything else.

So my question: What might be wrong? What might I check/adjust?

Thanks for any hint and suggestion. Regards . Götz

[Nagios-users] ADAPTIVE CHECK CHANGE_SVC_CHECK_COMMAND

[Javier Garces Asensio]

Hello everybody


I would like to use the external command change_svc_check_command to change
dinamically the warning and critical values of the checks. 
However it doesn´t work
I think the cause that it doesn't work is the modification introduced in the
version 3.0.6 (Disabled adaptive check and eventhandler commands for
security reasons ) as you can see in the URL:

http://www.nagios.org/projects/nagiosco ... ry/core-3x
 

I’m using the 3.2.1 version. 
In this version and also in the latest version 3.4.3, I can see the next
source code in the base/commands.c file

/* SECURITY PATCH - disable these for the time being */
switch(cmd) {
case CMD_CHANGE_GLOBAL_HOST_EVENT_HANDLER:
case CMD_CHANGE_GLOBAL_SVC_EVENT_HANDLER:
case CMD_CHANGE_HOST_EVENT_HANDLER:
case CMD_CHANGE_SVC_EVENT_HANDLER:
case CMD_CHANGE_HOST_CHECK_COMMAND:
case CMD_CHANGE_SVC_CHECK_COMMAND:
return ERROR;
}

I guess if I delete the above code, the external command
change_svc_check_command will work

Is not recommended to enable this external command?
Why was it disabled in the version 3.0.6? This is not resolved in the latest
version?
I haven´t found any official documentation about this

Thanks

Re: [Nagios-users] High check latency in a machine with low load

[Javier Vela Diago]

No, I don't stop mysql when I launch the optimize and repair. Should I?

In order to  launch mysqlcheck --repair and mysqlcheck --optimize, the 
database has to be started, no? I thougth that optimize and repair lock 
the tables by itself

Checks per second? I don't now for sure but 4000 services with 5 min of 
interval  gives us 14 checks/seconds. Moreover i know that i have a lots 
of times more than 80 concurrents checks at the same time (In the past i 
got some errors when reached the old limit of max_concurrent_checks=80)

Just to double check, are you locking your tables or stopping mysql when 
you do your repair runs?  You'll actually risk corrupting your DB tables 
which will tank your CPU if the tables are being written to while a 
repair run is occurring. 

As far as the checks go, how many checks per second is your machine 
running (on average)?

Re: [Nagios-users] High check latency in a machine with low load

[Javier Vela Diago]

Thank you for the advise, but due some problems in the past, I already 
have the mysql database in another machine with 2 cpus and 2GB of ram. 

Also, because of the problems I suffered, I have a script that every nigth 
optimizes and repairs the ndoutils database. My goal now is to change the 
engine from MyISAM to INNODB and apply some tunnig to the database. The 
engine change is because when  problems start, with MyISAM I have to 
truncate the database because optimize hangs out, but with InnoDB, in the 
tests I've made, works fine.

If ndoutils starts to create a heavy burden on the system you can also 
offload ndoutils/mysql to a second machine.  We wrote the below document 
for Nagios XI, but the doc has the info you'd need to make it work for 
Nagios Core as well.

Re: [Nagios-users] High check latency in a machine with low load

[Javier Vela Diago]

I have a lot of custom checks, written mostly in perl, bash and some in 
python. And some take a lo of time.

Nevermind, I think I found the solution, or at least one part. I 
configured to 1 the enable_large_instalallation_tweaks. This options, 6 
months ago, almost crashed my system, so i discarded it. Now, with bigger 
problems, is the last thing that I wanted to test, but finally this 
afternoon I tested  it.

When I restarted Nagios, the load has started to grow until 6-8,  and the 
latency problems dissapeared. I was sceptical about the utility of this 
options but when the load changes form 2,5 to 6, it means that the machine 
is doing a lot of work that before wasn't doing.

Now the problem is that NDOUtils is causing  some latency because of 
MYSQL, but well, at least I know what to optimize. Some tips will be 
apreciated :)

Thank you and sorry for your time.

I think you have the enable_high_latency option enabled J  j/k
 
Do you have any particular checks that are taking a long time?  i.e. can 
you watch top and see checks taking a while?

Hi, 

I have a Nagios 3.2.3 deployment with 1000+ Hosts and 3000+ services. This 
Nagios runs together with NDO and PNP (in bulk mode) in a server with 4GB 
of Ram and 4 cpus. 

One day I realized that the check delay in the performance CGI was very 
high (300-400 seconds). It was very strange so I took the tunning guide 
form nagios (http://nagios.sourceforge.net/docs/3_0/tuning.html) and 
applied all the points I could. In particular I adjusted the 
max_concurrent_checks to zero (no limit): 

max_concurrent_checks=0 

The reaper event: 

service_reaper_frequency=5 
max_check_result_reaper_time=15 

and checked that the host checks where not forced. In addition I 
configured 15 seconds of host check cache. 

cached_host_check_horizon=15 

But the problem remains. And the load of the server is not very high. Load 
of 2,5, 2 GB of free memory and an average utilization of disc of 7%. I 
disabled NDO and PNP but it was useless. After the first round of checks, 
the delay returns, while the load of the server doesn't grow. 

I have searched in google but all the problems area because of the load in 
the server, but here this is not the main problem. So my question is ¿what 
can I do now?¿There is some variable that shows me where to look? I'm a 
bit lost right now and I don't know how to find the problem. 

¿Or maybe the only way is to configure a master-slave nagios in order to 
maximize the server utilization? 

In addition, I have pretty big timeouts (60 seconds) because of the high 
latency on the network. All your help is appreciated. Thank you in 
advance.

Re: [Nagios-users] CPU performance with Nagios 3.2.3

[Javier González]

Thank you Yueh-Hung Liu,

Is it possible to discover what´s the problem with the Load, which processes
take all the CPU time periodically ???

Could i do something to improve the CPU usage ?

[Nagios-users] Fwd: Monitoring unmounted partition

[Javier Rivera]

  
  
  Good Morning, 

Im having a problem with check_nrpe. Im monitoring a partition
/mnt/2 f.e. If i dont have this partition mounted, it just
returns the value of "/" witout sending any error. 

How can i get an alert when the partition isn`t mounted.

Thanks in advance.

Sorry for my english. I write it also in spanish, if u use a
translator maybe u understand me better.

Estoy teniendo un problema con check_nrpe. Estoy monitorizando la
partición /mnt/2 por ejemplo. Si no tengo esta partición
montada, me devuelve la información de "/" y no da ningún error. 

¿Como puedo hacer para que salte alerta cuando no esta montada?.


Gracias

[Nagios-users] Advanced notifications configuration questions.

[Javier Domingo]

Hi everybody:
I'm working hard with Nagios 3.0.4 on Debian Lenny.
I have some questions. I can't find any information about these issues.
I have hosts with a first_notification_delay of 60 minutes.
And I have the whole day a Nagios controlling the same hosts. It's good to
know if the same host is turned on during the night, but my work period
begins at 10:00 am and it finish at 22:00 pm, I'm not a lucky boy [?]  So I
have configured a notification Period to 10:00 am to 22:00 pm.

Question 1: If a host goes into hard state CRITICAL, I know that Nagios
waits 60 minutes to send a notification, but What happens if the host
recovers before the first_notification_delay period ( for example, 30 min
before)?
Does it send the recovery notification or not?
Question 2: If a hard state happens at 21:59. Does Nagios wait until the
10:00 am of the day after to send the notification?
If the host recovers at 9:00 am of the day after is the notification message
cancelled?

Thanks a lot in advantace.

Re: [Nagios-users] RECOVERY in advanced notifications configuration questions.

[Javier Domingo]

Hi everybody:
 I'm working hardly with nagios 3.0.X over Debian Lenny.
 I have any questions. I don't find information about these issues
 about notification issues.
 I have any hosts with a first_notification_delay of 60 minutes.
 Question 1: If a host goes in hard critical state I know that
 nagios waits 60 minutes to send the notification CRITICAL, but , What
 happens if host RECOVERS before the first_notification_delay? It send
 the RECOVERY notification or not?

 I have 7x24 monitoring Nagios about the same hosts. It's useful
 because I can know if they are turned on during the night. But for me
 is very important that those hosts must be turned on from 10 to 22
 during the day. I have configured a Notification Period to
 10:00-22:00.
 Question2: if a host goes to CRITICAL STATE at 21:59 Nagios will wait 60
 minutes to send me a notification but, will Nagios wait until the to 10
 of the day after to send the notification? If host Recovers at 9:00 in
 the morning of the day after, nagios will cancel the CRITICAL/RECOVERY
 notifications messages?

 Thanks a lot in advance. Sorry about my English.

It seems to be something in the way Apache handles PHP.  Since there's 
no PHP code in the index.php page, we've found here that just renaming 
it to index.html brings back the old behavior.

Re: [Nagios-users] newbie questions

[Javier]

hello,

thanks in advance for your kind andwers..

here's what i did on the websphere:

a created a new command definition

# 'check_http_websphere' command definition
define command{
command_namecheck_http_websphere
command_line$USER1$/check_http -H $HOSTADDRESS$ -p 9080 -u
http://172.18.52.141:9080/eibs_bancoagricola/
}

and i created a new command for the tcp as well:


# 'check_tcp_websphere' command definition
define command{
command_namecheck_tcp_websphere
command_line$USER1$/check_tcp -H $HOSTADDRESS$ -p 9060  $ARG1$
}

here's the thing, websphere answers in the 9060 for the management
console, and on the 9080 for the appl, but it redirects to the 9043
(ssl)

is it ok so far what im doing?, i think i'm checking the url in the
hhtp command... should i created a new command for the 9043 port?

[Nagios-users] newbie questions

[Javier]

Hello,

i have installed nagios yesterday and i have a check_ping on 4
servers, a check_http on an apache server and a check_mysql on another
one

but i have a lot of websphere servers and i would like to add them to
my nagios platform, they answer on the 9080, 9043 and 9060 ports, is
there a plugin for websphere?, or do i have to modify only the
commands.cfg for websphere?

i also have another question, if i want to check a socket on iseries
(as400), is it ok to use the check_tcp plugin?, has anyone use it
before?

Re: [Nagios-users] newbie questions v. 2.0

[javier rojas]

for example, i only have localhost configured on nagios, and it had
the same path

and it's working, but i really tried that before

#cfg_file=/usr/local/nagios//etc/hosts.cfg
#cfg_file=/usr/local/nagios/etc/hosts.cfg

# Command definitions
cfg_file=/usr/local/nagios//etc/commands.cfg

# Host and service definitions for monitoring this machine
cfg_file=/usr/local/nagios//etc/localhost.cfg

[Nagios-users] newbie questions v. 2.0

[javier rojas]

Hello,

i know that probably this is a low level questions but i have read the
documentation of nagios and still have some questions...

i have created a hosts.cfg file in order to place my servers, and i
started it with a w$ 2k3 vmware virtual server on my machine heres
the file:

define host{
host_name   testserver
alias   test server windows
address 192.168.0.5
parents
check_command   check-host-alive
max_check_attempts  5
check_period24x7
process_perf_data   0
retain_nonstatus_information0
contact_groups  nagios-admins
notification_interval   30
notification_period 24x7
notification_optionsd,u,r
}

here's my question:

i can resolve hte name from my mahcine of the server, i did not
created a nagios-admins group, and i have the original command.cfg
file, and when i insert in my nagios.cfg the line so it should search
for hosts on the new file i cant restart nagios and i get an error
CONFIG ERROR!  Start aborted.  Check your Nagios configuration

heres the line:
cfg_file=/usr/local/nagios//etc/hosts.cfg

just below object configuration file

i have checked according to the docs, the files and it's order...but i
really can't find the error, i would really like to know how to add
hosts and services to nagios...

Re: [Nagios-users] problem installing nagios 2.6

[javier rojas]

sorry to trouble again folks, but i cannot seem to be able to make it work...

i've tried make install-config before and after make install-init and
in both cases i have the same problem

it actually creates the /etc folder but inside its only:
cgi.cfg-sample  commands.cfg-sample  localhost.cfg-sample
nagios.cfg-sample  resource.cfg-sample

and when i try to browse to localhost/nagios
i get a server error because theres no:
/usr/local/nagios/etc/htpasswd.users

on my /etc directory

i know im a newbie but i really followed the instructions and couldn
get it to workso if anyone can see my istake i would really
appreciate it

[Nagios-users] SOLVED: RE: Plugin error: Remote cisco command via SSH notworking

[Javier Castillo Alcibar]

Hello,

I think I solved the problem. Notice this command in my perl script: 
"$ENV{'HOME'} = '/var/lib/nagios';"
 
Nagios process was executing the plugin with HOME env varible set to "/root" 
¿?¿?.  This made ssh fails when trying to read $HOME/.ssh/config files 
(root folder is not readable by other users)

Finally, my contribution to nagios world: check_cisco_ping_ssh (ping from cisco 
routers, using ssh):

#!/usr/bin/perl
# Net::SSH de http://www.stupidfool.org/perl/net-ssh/
#
# Use: usr/local/sbin/check_cisco_ping_ssh  
 
#
use strict;

use Net::SSH::Perl;

$ENV{'HOME'} = '/var/lib/nagios';
 
my $router=$ARGV[0];
my $port=$ARGV[1];

my $user=$ARGV[2]; 
my $pass=$ARGV[3]; 

my $ip=$ARGV[4]; 

my $warn=$ARGV[5]; 
my $crit=$ARGV[6]; 



my $sesion_ssh = Net::SSH::Perl->new($router, protocol=>1, cipher=>'DES', 
port=>$port, debug=> 'false'); 
$sesion_ssh->login($user, $pass);

my $comand="ping $ip";

my($output, $output_error, $value_exit) = $sesion_ssh->cmd($command);

$output =~ /Success rate is (\d*) (.*)/;

my $rate=$1;

if ( $rate <= $crit ) {
print "PROBLEM: Rate=$rate%\n";
exit 2;
}

if ( $rate <= $warn ) {
print "WARNING: Rate=$rate%\n";
exit 1;
}

if ( $rate <= 100 ) {
print "OK: Rate=$rate%\n"; 
exit 0;
}

exit 3;

 

Enjoy it.

Have you compiled nagios with embedded perl support? If so, use /usr/bin/perl 
/path/to/your/script.pl

instead of just

/path/to/your/script.pl

in the command definition.

Other than that, make sure that the nagios-user has access to execute the 
script and try it from the command-line *as the nagios user*. If that works, 
you've made some mistake in your configuration.

Re: [Nagios-users] Plugin error: Remote cisco command viaSSH notworking

[Javier Castillo Alcibar]

Pherhaps.. Do you know how to run a plugin from nagios like root. My nagios 
process run as nagios user. (Debian/Sarge)

But, if I run the plugin from a command line, and with user nagios (su - 
nagios), the plugin works as expected.

I am confused.

thx

Asunto: [Nagios-users] Plugin error: Remote cisco command via SSH
notworking

Hello all,
 
I have some cisco routers that can only be managed using SSH. I wrote an
script, to do remotely some PING's from these routers, integrated in
nagios.

My problem is very strange:
- if a execute this script from the command line by myself, it
works as expected.
- if nagios process executes the script, it does not work. It
looks like ssh process didn't return anything

I think it's a problem related with ttys.but I'm not sure.

This is my (perl) script:

#!/usr/bin/perl
#
# Uso: usr/local/sbin/check_cisco_ping_ssh
   # use Net::SSH::Perl;

$router=$ARGV[0];
$port=$ARGV[1];
$user=$ARGV[2];
$pass=$ARGV[3];
$ip=$ARGV[4];
$warn=$ARGV[5];
$crit=$ARGV[6]; 

my $sesion_ssh = Net::SSH::Perl->new($router, protocol=>1,
cipher=>'DES', port=>$port); $sesion_ssh->login($user, $pass);

$command="ping $ip";

my($output, $output_error, $val_exit) = $sesion_ssh->cmd($command);

$output =~ /Success rate is (\d*) (.*)/; $rate=$1;

if ( $rate <= $crit ) {
print "PROBLEM: PING Rate=$rate%\n";
exit 2;
}
if ( $rate <= $warn ) {
print "WARNING: PING Rate=$rate%\n";
exit 1;
}
if ( $rate <= 100 ) {
print "OK: PING Rate=$rate%\n"; 
exit 0;
}
exit 3;


Any help is welcome!!.

Thx in advance.
Regards

[Nagios-users] Engaging nagios notifications and helpdesk software

[Javier Palacios]

Hello,

I'm working to integrate notifications into our helpdesk. It looks
promising and the initial work has been quite successful. The
notification command creates a ticket using a webservice, and  writes
an acknoledgement upon successful creation. This setup is functional,
but does not satisfy me because nagios and helpdesk are quite
decoupled.

I might prefer to get a two direction communication, basically to only
ACK the problem when some human being actually works on the ticket,
and also to close the ticket (the proper one) if the service recovers.
One of the problems I see is how to assign a unique identifier to a
nagios alarm, which might solve most of my problems as our helpdesk is
designed to cooperate with external helpdesk applications.

I would like to get feedback and comments for people who has (or not)
such a setup.

Javi
