“centreon-plugins” is a free and open source project to monitor systems. The project can be used with Centreon and all monitoring softwares compatible with Nagios plugins.
You can monitor many systems:
- application: Apache, Asterisk, Elasticsearch, Github, Jenkins, Nginx, Pfsense, Tomcat, Varnish,...
- database: Informix, MySQL, Postgres, Oracle, MS SQL
- hardware: printers (rfc3805), UPS (Powerware, Mge, Standard), Sun Hardware, Cisco UCS, SensorIP, HP Proliant, HP Bladechassis, Dell Openmanage, Dell CMC,
- network: Aruba, Brocade, Bluecoat, Brocade, Checkpoint, Cisco AP/IronPort/ASA/Standard, Extreme, Fortigate, H3C, Hirschmann, HP Procurve, F5 BIG-IP, Juniper, PaloAlto, Redback, Riverbed, Ruggedcom, Stonesoft,...
- os: Linux (SNMP, NRPE), Freebsd (SNMP), AIX (SNMP), Solaris (SNMP)...
- storage: EMC Clariion, Netapp, HP MSA p2000, Dell EqualLogic, Qnap, Panzura, Synology...
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;
