check_srx_cluster

Project Notes

This check plugin is intended to check Juniper SRX firewall cluster status. I needed this as I couldn't read the documented SNMP id (e.g. .1.3.6.1.2.1.15.3.1.2) as this is not present on my equipment somehow. (SRX240B)

This script is an expect script so you have to have expect and ssh installed.

Syntax of the script:
check_srx_cluster {HOSTADDRESS} {prompt} {loginuser} {loginpassword}
e.g.: ./check_srx_cluster 1.2.3.4 srxfw nagios verysecret
Hhere is the example for the prompt:
nagios@srxfw>
in this case {prompt} will be 'srxfw'

You need to configure a command in nagios:
define command {
command_name check_srx_cluster
command_line $USER2$/check_srx_cluster $HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$
}

And a service for the firewall host:
define service {
service_description CLUSTER_STATUS
host_name srxfw
use generic-service
check_command check_srx_cluster!srxfw!nagios!verysecret
check_interval 15
stalking_options o,w,c
}

Hope you enjoy this! :)
