Hello Vladimir,
(Your mail somehow went to the spam folder, thank god I checked the spam folder)
My data source has already a polling interval of 1 second.
By searching more, I found out that these samples from polling get averaged
from the rrd-tool into a 15 second resolution and I really don't want that.
Can I configure gmetad to make rrd's with step (or resolution) of 1-3 seconds
and hold data for a day max?
They will be stored in a processed form after I finish my tasks and I won't
need the ganglia service 24/7.
Thanks,
Theofilos Mouratidis.

Hi Theofilos,
by default gmetad polls gmonds every 15 seconds and inserts them
into RRDs. You can attempt to change that by adding the polling
interval e.g. 1-3 seconds in gmetad.conf. To do so you would add
it after the grid name e.g.
data_source "my grid" 50 1.3.4.7:8655
sets polling period of 50.
This all said polling period of 1 second may be a bit too
aggressive depending on the size of your cluster.

I have a cluster and I
want to get metrics every 1-3 seconds, to benchmark some
algorithms on spark.
I’ve set the data_source
“my cluster name” 1 hosts…. (multicast).
The UI on the hours tab,
gives me the results in every 12 seconds, that’s too chunky
for what I want to accomplish.
I used the rrdtool
export –step 1 etc… and I don’t get the results every
second.
What did I wrong?
