Check Cluster Table

-------------------

This is a variation on the check_cluster nagios check. It's mainly useful for

low power devices, or very busy machines that continuously run at a high load.

Reasoning and info available here:

*INSTALL*

Example:

----

wget https://raw.githubusercontent.com/mclarkson/check_cluster_table/master/check_cluster_table

chmod +x check_cluster_table

mv check_cluster_table /usr/lib/nagios/plugins/

----

*EXAMPLE OUTPUT*

----

CLUSTER OK: 0 warning, 1 critical. | 'cluster problems'=1;

CLUSTER WARNING: Match for '1,0,1'. 1 warning, 1 critical.  | 'cluster problems'=2;

CLUSTER CRITICAL: Match for '1,1,1'. 1 warning, 2 critical. | 'cluster problems'=3;

$ ./check_cluster_table -h

check_cluster_table - Check a number of results against a table.

Usage: check_cluster_table (-s | -H) (-t col1[,col2,..,colN])*

    -c NUM -d col1[,col2,..,colN]

 -h      : Display this help text.

 -S      : Check services.

 -H      : Check hosts.

 -t STR  : Valid statuses. Use one or more times. Comma delimited.

           Use 1 or 0 only.

 -d STR  : The current service or host statuses. Comma delimited.

 -c NUM  : If the number of criticals in the '-d' option exceeds

           NUM then this plugin will return critical. Default 2.

           For Host checks this option relates to the number of

           host that are in a non-OK state.

Examples:

If -d option represents Load, CPU, Swap Activity then the following

will NOT alert when cpu and load are both warning/critical nor when

CPU usage alone is warning/critical.

 ./check_cluster_table -S -t 1,1,1 -t 0,1,1 -t 1,0,1 -t 0,0,1 \

    -d 0,1,0
