harvest counters

[maskajan09]

Hello

I'm new to the harvest and I'm really lost. I use Nabox with harvest 1.6 right now. I would like to know which counters (mainly IOPS, latency and throughput) are related to the frontend and which are related to the backend (aggregate). Is there anywhere list of collected counters with some explanation? And also the list of commands used by harvest to collect the counters.

Thank you

Jan

Hi Jan,

You can take a look at the template file, which lists the objects and counters that are collected by Harvest. E.g. open template/default/cdot-9.6.0.conf (or replace "9.6.0" with the version that most closely matches to your cDot).

Next, you can use the utility util/perf-counters-utility to get info of about the counters. E.g. to see the counters of object volume, run:

/util/perf-counters-utility -host HOST -user USER -pass PASS -f volume -c

(replace HOST, USER, PASS with the hostname, usename and password of your Cdot system).

You can also use this utility to explore objects / counters that are not collected by Harvest, add them to the template to make Harvest collect them.

Let me know if you need more help.
