[rrd-users] Minimum resolution for fetching data

The minimum resolution you can fetch is the minimum resolution of all the RRAs which completely cover the time window you are asking for.

The minimum resolution of an RRA is 1 interval, and the minimum interval is 1 second.  Both of these are set at RRD creation time, and have an implication on data collection and update frequency.

If you are only getting 1 minute resolution data, I suspect you have a 1minute Interval on your RRD with a count-1 RRA.

Subject: [rrd-users] Minimum resolution for fetching data

Hello list,

I googled this but could not come up with anything definitive, so I
thought I'ld ask here.

I work for a client that uses Citrix a lot. This means that it sometimes
is important to get graphs in one second resolution. I cannot seem to
get rrdtool to do so, the minimum resolution it will come up with is 1

My question, is this my mistake somehow, or is this RRD design? If
needed I'll post details about how I create the RRDs and how I fill them.
