We'll use a basic example to show you how to monitor a system. I have finished the install section and i want to monitor a Linux in SNMP.
First, i need to find the plugin to use in the list:
::
$ perl centreon_plugins.pl --list-plugin | grep -i linux | grep 'PLUGIN'
PLUGIN: os::linux::local::plugin
PLUGIN: os::linux::snmp::plugin
It seems that 'os::linux::snmp::plugin' is the good one. So i verify with the option `` --help `` to be sure:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --help
...
Plugin Description:
Check Linux operating systems in SNMP.
It's exactly what i need. Now i'll the option `` --list-mode `` to know what can i do with it:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --list-mode
...
Modes Available:
processcount
time
list-storages
disk-usage
diskio
uptime
swap
cpu-detailed
load
traffic
cpu
inodes
list-diskspath
list-interfaces
packet-errors
memory
tcpcon
storage
I would like to test the 'load' mode:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=load
UNKNOWN: Missing parameter --hostname.
It's not working because some options are missing. I can have a description of the mode and options with the option `` --help `` :
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=load --help
Eventually, i have to configure some SNMP options:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=load --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public
OK: Load average: 0.00, 0.00, 0.00 | 'load1'=0.00;;;0; 'load5'=0.00;;;0; 'load15'=0.00;;;0;
I can set threshold with options `` --warning `` and `` --critical `` :
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=load --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --warning=1,2,3 --critical=2,3,4
OK: Load average: 0.00, 0.00, 0.00 | 'load1'=0.00;0:1;0:2;0; 'load5'=0.00;0:2;0:3;0; 'load15'=0.00;0:3;0:4;0;

What can i monitor ?
--------------------
The option `` --list-plugin `` can be used to get the list of plugins and a short description.
Headers of the table mean:

How can i remove perfdatas ?
----------------------------
2015-01-06 11:48:40 +01:00
For example, i check TCP connections from a linux in SNMP with following command:
2014-12-18 17:34:53 +01:00
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=tcpcon --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public
OK: Total connections: 1 | 'total'=1;;;0; 'con_closed'=0;;;0; 'con_closeWait'=0;;;0; ' con_synSent'=0;;;0; 'con_established'=1;;;0; 'con_timeWait'=0;;;0; 'con_lastAck'=0;;;0 ; 'con_listen'=5;;;0; 'con_synReceived'=0;;;0; 'con_finWait1'=0;;;0; 'con_finWait2'=0; ;;0; 'con_closing'=0;;;0;
2015-01-06 11:48:40 +01:00
2014-12-18 17:34:53 +01:00
There are too many perfdatas and i want to keep 'total' perfdata only. I use the option `` --filter-perfdata='total' `` :
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=tcpcon --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --filter-perfdata='total'
OK: Total connections: 1 | 'total'=1;;;0;
I can use regexp in `` --filter-perfdata `` option. So, i can exclude perfdata beginning by 'total':
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=tcpcon --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --filter-perfdata='^(?!(total))'
OK: Total connections: 1 | 'con_closed'=0;;;0; 'con_closeWait'=0;;;0; 'con_synSent'=0;;;0; 'con_established'=1;;;0; 'con_timeWait'=0;;;0; 'con_lastAck'=0;;;0; 'con_listen'=5;;;0; 'con_synReceived'=0;;;0; 'con_finWait1'=0;;;0; 'con_finWait2'=0;;;0; 'con_closing'=0;;;0;
------------------------------------------------
How can i set threshold: critical if value < X ?
------------------------------------------------
2015-01-06 11:48:40 +01:00
"centreon-plugins" can manage Nagios threshold ranges: https://nagios-plugins.org/doc/guidelines.html#THRESHOLDFORMAT
2014-12-18 17:34:53 +01:00
For example, i want to check that 'crond' is running (if there is less than 1 process, critical). I have two ways:
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=processcount --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --process-name=crond --critical=1:
CRITICAL: Number of current processes running: 0 | 'nbproc'=0;;1:;0;
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=processcount --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --process-name=crond --critical=@0:0
CRITICAL: Number of current processes running: 0 | 'nbproc'=0;;@0:0;0;
------------------------------------------
How can i check a generic SNMP OID value ?
------------------------------------------
There is a generic SNMP plugin to check it. An example to get 'SysUptime' SNMP OID:
::
$ perl centreon_plugins.pl --plugin=snmp_standard::plugin --mode=numeric-value --oid='.1.3.6.1.2.1.1.3.0' --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public

How can i check ipv6 equipment in SNMP ?
----------------------------------------
To check ipv6 equipment, use the following syntax (`` udp6:[xxxx] `` ):
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --hostname='udp6:[fe80::250:56ff:feb5:6ae0]' --mode=storage --snmp-version=2c --snmp-community=public

How to use memcached server for retention datas ?
-------------------------------------------------
Some plugins need to store datas. Two ways to store it:
2015-01-06 11:48:40 +01:00
* File on a disk (by default).
* Memcached server.
2014-12-19 11:27:01 +01:00
To use 'memcached', you must have a memcached server and the CPAN 'Memcached::libmemcached' module installed.
You can set the memcached server with the option `` --memcached `` :
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=traffic --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --verbose --skip --skip-speed0 --memcached=127.0.0.1
OK: All traffic are ok | 'traffic_in_lo'=197.40b/s;;;0;10000000 'traffic_out_lo'=197.40b/s;;;0;10000000 'traffic_in_eth0'=14539.11b/s;;;0;1000000000 'traffic_out_eth0'=399.59b/s;;;0;1000000000 'traffic_in_eth1'=13883.82b/s;;;0;1000000000 'traffic_out_eth1'=1688.66b/s;;;0;1000000000
Interface 'lo' Traffic In : 197.40b/s (0.00 %), Out : 197.40b/s (0.00 %)
Interface 'eth0' Traffic In : 14.54Kb/s (0.00 %), Out : 399.59b/s (0.00 %)
Interface 'eth1' Traffic In : 13.88Kb/s (0.00 %), Out : 1.69Kb/s (0.00 %)
.. tip ::
Local file is used if the memcached server is not responding.

------------------------------------
What does `` --dyn-mode `` option do ?
------------------------------------
With the option, you can used a mode with a plugin. It commonly used for database checks.
For example, i have an application which stores some monitoring information on a database. The developer can use another plugin to create the check (no need to do the SQL connections,... It saves time):
::
$ perl centreon_plugins.pl --plugin=database::mysql::plugin --dyn-mode=apps::centreon::mysql::mode::pollerdelay --host=10.30.3.75 --username='test' --password='testpw' --verbose
OK: All poller delay for last update are ok | 'delay_Central'=2s;0:300;0:600;0; 'delay_Poller-Engine'=2s;0:300;0:600;0;
Delay for last update of Central is 2 seconds
Delay for last update of Poller-Engine is 2 seconds
.. warning ::
A mode using the following system must notice it (in the help description). So you should open the file with an editor and read at the end the description.
2014-12-19 13:40:59 +01:00
------------------------------------
How can i check the plugin version ?
------------------------------------
You can check the version of plugins and modes with option `` --version `` :
::
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --version
Plugin Version: 0.1
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=storage --version
Mode Version: 1.0
You can also use the option `` --mode-version `` to execute the mode only if there is the good version.
For example, we want to execute the mode only if the version >= 2.x:
2015-01-02 11:03:44 +01:00
::
2014-12-19 13:40:59 +01:00
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=storage --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --verbose --mode-version='2.x'
UNKNOWN: Not good version for plugin mode. Excepted at least: 2.x. Get: 1.0

I get the SNMP error: 'UNKNOWN:.* (tooBig).* '
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following error can happened with some equipments.
You can resolve it if you set following options:
* `` --subsetleef=20 `` `` --maxrepetitions=20 ``
I get the SNMP error: 'UNKNOWN:.*Timeout'
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following error means:
2015-01-06 11:48:40 +01:00
* Don't have network access to the target SNMP Server (a firewall can block UDP 161).
* Wrong SNMP community name or SNMP version set.
2014-12-18 17:34:53 +01:00
I get the SNMP error: 'UNKNOWN:.*Cant get a single value'
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following error means: SNMP access is working but you can't retrieve SNMP values.
Very possible reasons:
2015-01-06 11:48:40 +01:00
* SNMP value is not set yet (can be happened when a SNMP server is just started).
* SNMP value is not implemented by the constructor.
* SNMP value is set on a specific firmware or OS.
2014-12-18 17:34:53 +01:00
Seems that process check is not working well for some arguments filter
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2015-01-06 11:48:40 +01:00
In SNMP, there is a limit in argument length of 128 characters.
So, if you try to filter with an argument after 128 characters, it won't work. It can happen with Java arguments.
2014-12-18 17:34:53 +01:00
To solve the problem, you should prefer a NRPE check.
Can't access in SNMP v3
^^^^^^^^^^^^^^^^^^^^^^^
First, you need to validate SNMP v3 connection with snmpwalk. When it's working, you set SNMP v3 options in command line.
2015-01-06 11:48:40 +01:00
The mapping between 'snmpwalk' options and "centreon-plugins" options:
2014-12-18 17:34:53 +01:00
* -a => `` --authprotocol ``
* -A => `` --authpassphrase ``
* -u => `` --snmp-username ``
* -x => `` --privprotocol ``
* -X => `` --privpassphrase ``
* -l => not needed (automatic)
* -e => `` --securityengineid ``
* -E => `` --contextengineid ``

2014-12-18 17:34:53 +01:00
I get the error: "UNKNOWN: Need to specify '--custommode'."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Some plugins need to set the option `` --custommode `` . You can know the value to set with the option `` --list-custommode `` . An example::
$ perl centreon_plugins.pl --plugin=storage::ibm::DS3000::cli::plugin --list-custommode
...
Custom Modes Available:
smcli
$ perl centreon_plugins.pl --plugin=storage::ibm::DS3000::cli::plugin --custommode=smcli --list-mode
2014-12-19 11:27:01 +01:00
I get the error: "UNKNOWN: Cannot write statefile .*"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You must create the directory (with write permissions) to let the plugin stores some datas on disk.
I get the error: "UNKNOWN: Cannot load module 'xxx'."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The problem can be:
2015-01-06 11:48:40 +01:00
* A prerequisite CPAN module is missing. You need to install it.
* The CPAN module cannot be loaded because of its path. Perl modules must be installed on some specific paths.
