This plugin checks the CPU load of AVAYA S8xxx media servers, accessing Avaya's SNMP agent with G3-AVAYA-MIB Version 5.1.1. It returns the total CPU usage and idle values in percent, checked against warning and critical threshold values. When called with the -f option, it returns additional CPU usage details in the performance data section.

It requires SNMP access to the Avaya media server, which is configured in the management console. The plugin depends on Perl's Net::SNMP package, i.e. perl-SNMP-

Usage: [-v] -H <host> -C <snmp_community> [-2] | (-l login -x passwd [-X pass -L <authp>,<privp>]) [-p <port>] -w <warn level> -c <crit level> [-f] [-t <timeout>] [-V]


-v, --verbose
      print extra debugging information

-h, --help
      print this help message

-H, --hostname=HOST
      name or IP address of host to check

-C, --community=COMMUNITY NAME
      community name for the host's SNMP agent (implies v1 protocol)

-2, --v2c
      Use snmp v2c

-l, --login=LOGIN ; -x, --passwd=PASSWD
      Login and auth password for snmpv3 authentication
      If no priv password exists, implies AuthNoPriv

-X, --privpass=PASSWD
      Priv password for snmpv3 (AuthPriv protocol)

-L, --protocols=<authproto>,<privproto>
      <authproto> : Authentication protocol (md5|sha : default md5)
      <privproto> : Priv protocole (des|aes : default des)

-p, --port=PORT
      SNMP port (Default 161)

-w, --warn=INTEGER
      warning level for cpu in percent

-c, --crit=INTEGER
      critical level for cpu in percent

-f, --perfparse
      Perfparse compatible output

-t, --timeout=INTEGER
      timeout for SNMP in seconds (Default: 5)

-V, --version
      prints version number

Plugin Definition Example:

Plugin Usage Example:

The plugin with its most basic use.

susie: ~ # cd /srv/app/nagios/libexec
susie: ~ # ./ -H -C SECro -w 75 -c 95
Avaya CPU: 9% used, 91% free : OK

The plugin with the -f option, returning additional performance data.

susie: ~ # cd /srv/app/nagios/libexec
susie: ~ # ./ -H -C SECro -w 75 -c 95 -f
Avaya CPU: 6% used, 94% free : OK | load_os=0; load_call=1; load_mgt=5; load_idle=94;
