Asked on XI about the ability to monitor the availability of all nodes in a hostgroup. A few of our hostgroups define clusters, therefore need to know how much of the cluster is up, and alert on too many nodes being down. Also need to see history over time of %nodes up. Sam took up the challenge and within a week developed this plugin. Very flexible command parameters. Fills our need to know condition of hostgroups, be notified and have a record of same. Thanks very much!
