Can you give some example output from the ceph -s command

I have a JSON parser that takes simple JSON and makes it parsable for bash scripts. Then you could use an external command wrapper and parse the output in Nagios style..

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.

You can transform "ceph -s -f json" output to standard Zenoss json format and then you can use Zenoss JSON parser http://wiki.zenoss.org/JSON_Parser. Data related to cluster can be easy parsed. Problem can be with data for nodes. You can hardcode node metrics in cluster template or standard solution is that you create another "component" template for cluster components - nodes.

I haven't actually found the json parser, nor how to implement the parser into my environment. I only have auto, cacti, nagios, and the other zenoss specific parsers in my drop down menu. If i had the json parser, it seems easy enough to format it with json and have it parse it out very easily. I just can't seem to find the parser or how to implement it into zenoss.

Yep, JSON parser is only in newer versions. Anyway you can download and use it:
http://dev.zenoss.org/trac/browser/tags/zenoss-4.2.5/Products/ZenRRD/par... - just download/upload and restart Zenoss.
