Re: [pcp] Trying out ElasticSearch PMDA for the first time

Nathan and Paul,

Many thanks and the cat api looks very nice. It will even help us work out some performance issues ( > 300k events per minute).

I will try and look through the PMDA and work out which of the GET's are failing, looking at the pminfo output it seems all of them are. So it is possible that they have been removed from the API, as Paul says.

I will try and locate the GET API doc. Paul if you know it off the top of your head, let me know
