I am looking for a solution to gather, correlate and graph large sets of
data.
The data is gathered from several hundred servers (going upto multi-1000
within 12 month).
Requirements are:
* 1 minute resolution of data
* individual graphs of a single value stream (e.g. IOPS for a given
block device)
* Graphs over a bunch of value streams (e.g. max IOPS per minute on
100ish block devices together)
* Data Retention in this resolution for 90 days
Commercial, not free, not open source, but... the data handling and
correlation part sounds like a job for Streambase. Graphing would be a
separate matter.
