Metric values are not correct in New Relic #24

Open foobarnum opened 10 years ago

foobarnum commented 10 years ago

We have both datastax opscenter and the 3 legs plugin installed. Were weighing NewRelic as a cassadra monitoring option because it ties in to our alert messaging while this is a paid feature in datastax. Unfortunately the nubers we're getting with the 3legs plugin don't really make sense while the datastax monitoring is largely accurate. Is there tweaking that needs done on our end with the plugin, or is there a bug in the way numbers are gathered and calculated. In the picture below the right pane is datastax and can be taken as a close representation of what is actually going on.

I believe the read metric discrepancy is at least partially fixed by https://github.com/threelegs/newrelic-plugins/pull/29.

Another change that made an even larger improvement is in https://github.com/threelegs/newrelic-plugins/pull/31

@foobarnum Out of interest, are you using C* 2.x? We're currently evaluating New Relic and I'd also like to have C* monitoring in place. From the README it sounds as if only 1.2.x would be supported,...
