Nagios plugin to check the status of a Sun Cluster for Solaris (version 3.2 or greater).
The 3.2 release of Solaris Cluster introduced an all-new Command Line Interface for managing the cluster. These are the equivalences between the previous and the new commands used to get the cluster status:
+------------------+-----------------+-------------------------+
| | Sun Cluster 3.1 | Sun Cluster 3.2 |
+------------------+-----------------+-------------------------+
| Nodes | scstat –n | clnode status |
| Quorum | scstat –q | clqorum status |
| Transport info | scstat –W | clinterconnect status |
| Resources | scstat –g | clresource status |
| Resource Groups | scstat -g | clresourcegroup status |
+------------------+-----------------+-------------------------+
In your Nagios plugins directory (in one of the nodes of the Sun Cluster) run:
git clone git://github.com/rafacas/nagios-plugin-sun-cluster.gitEdit your commands.cfg in your Nagios server and add the following (we are using NRPE to connect to the nodes):
define command {
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
The plugin uses the command clnode status to get the node status:
$clnode status

The following are the possible states of a node:
+-------------+---------------+
