Basic Usage
|
|
***********
|
|
|
|
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;

How can i remove perfdatas ?
|
|
----------------------------
|
|
|
|
For example, i check tcp connections from a linux in SNMP with following command:
|
|
::
|
|
|
|
$ 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;
|
|
|
|
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':

How can i set threshold: critical if value < X ?
|
|
------------------------------------------------
|
|
|
|
"centreon-plugins" can manage nagios threshold ranges: https://nagios-plugins.org/doc/guidelines.html#THRESHOLDFORMAT
|
|
|
|
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 to use memcached server for retention datas ?
|
|
-------------------------------------------------
|
|
|
|
Some plugins need to store datas. Two ways to store it:
|
|
|
|
* File on a disk (by default)
|
|
* Memcached server
|
|
|
|
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.
|
|
|
|
------------------------------------
|
|
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:
|
|
::
|
|
|
|
$ 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
|

Troubleshooting

SNMP

|
|
|
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:
|
|
|
|
* Don't have network access to the target SNMP Server (a firewall can block UDP 161)
|
|
* Wrong SNMP community name or SNMP version set
|
|
|
|
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:
|
|
|
|
* 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
|
|
|
|
Seems that process check is not working well for some arguments filter
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
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.
|
|
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.
|
|
The mapping between 'snmpwalk' options and centreon plugin options:
|
|
|
|
* -a => ``--authprotocol``
|
|
* -A => ``--authpassphrase``
|
|
* -u => ``--snmp-username``
|
|
* -x => ``--privprotocol``
|
|
* -X => ``--privpassphrase``
|
|
* -l => not needed (automatic)
|
|
* -e => ``--securityengineid``
|
|
* -E => ``--contextengineid``
|

I use an option but it doesn't seem to work
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Before opening a ticket on the forge, please use the option ``--sanity-options``. It checks if you have misspell an option:
|
|
::
|
|
|
|
$ perl centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=traffic --hostname=127.0.0.1 --snmp-version=2c --snmp-community=public --interface='.*' --name --regex --verbose --skip --skip-speed0 --sanity-options
|
|
Unknown option: regex
|
|
|
|
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
|
|
|
|
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:
|
|
|
|
* 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
|
|
|
|
I can't see help messages
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
"centreon-plugins" files must unix format (no windows carriage returns). You can change it with the following command:
|
|

|
|
|
|
$ find . -name "*.p[ml]" -type f -exec dos2unix \{\} \;
|
|
|
|
