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':
|
||||
::
|
||||
|
||||
$ 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

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 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
