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;

FAQ
===
--------------------
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:
* Transport: The check has internal options for the transport
* Protocol: what is used to get the monitoring datas
* Experimental: The check is still in development

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':
::
$ 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 ?
------------------------------------------------
"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

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``
-------------
Miscellaneous
-------------
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
