Pull the metrics out of couchbase like QPS, gets/sec etc and plot them on the graph as Couchbase UI does .. As I have a personal program which continuosly can poll couchbase for all this data and plot them on a graph .. .
IS there an API call I can make to fetch these metrics for a specific bucket/server and plot them on the graph using my own program??
The location of cbstats is documented here: http://www.couchbase.com/docs/couchbase-manual-2.1.0/couchbase-admin-cmdline-cbstats.html
Also you can use the REST API to get some stats: http://www.couchbase.com/docs/couchbase-manual-2.1.0/couchbase-admin-restapi.html
