I know rrdtool (and the jrobin equivalent in java) can do it, but that's a
fairly low level tool. I was hoping to find some generic framework that could
accept either counter or gauge type values and do the rest for you including a
web graph display. I'd think this would be a common problem but I haven't found
any high-level tools that aren't married to snmp for the input.

hi, i am newbie to memcached. I need help in finding how to get
throughput stat.
I want to see how much throughput memcache is getting.
"stats" command
does not list any stat for through put (requests per sec).
Any idea on
how to go about getting that info? Does memcache keep track
of this
information?
It's rare to keep derived stats like that in general. It's usually
not interesting. Do you want average requests per second over the
lifetime of the process? Over the last second?, 60 seconds?
300, 900,
3600, etc...
Most of the time, this is easily observable from the outside.
Collect counters -- wait a bit, collect them again, then do your own
math. That'll give you exactly what you want.
It's a bit off topic for this list, but does anyone know if there
are good generic tools for that? There are quite a few designed to
convert SNMP 'COUNTER' types to rates, check thresholds and keep
history to graph the trends, but usually the SNMP sampling is
closely coupled to the rest of the logic. I think OpenNMS might do
it with values it can pick up with http requests but I'm not sure
how well it handles the spikes that would appear from restarts and
value rollovers.
