Trying out ElasticSearch PMDA for the first time

[Chandana De Silva <chandana@xxxxxxxxxxxxx>]

Hello All
I am trying out the ES pmda, and not having much luck.

The error in the PMCD log says:
[Thu Apr  2 06:20:40] pmcd(2564) Warning: pduread: timeout (after 5.000 sec) while attempting to read 12 bytes out of 12 in HDR on fd=21
[Thu Apr  2 06:20:40] pmcd(2564) Info: CleanupAgent ...

This is what I have:
