Adding ability to refresh counter every x minutes/hours #10

Closed zeugfr closed 9 years ago

zeugfr commented 9 years ago

Hi,

I would like to propose a little enhancement : is it possible to add an auto-refresh of all counters (like when I do a "counter list" in the console) in a regular time basis (every x minutes or hours) ? I have for example counters on SQL Server on databases (counter instance = *), so each time I create a new db, I have to refresh the counters to get the new db metrics.

Thanks for your great work !

This is a great idea. It is also needed if you want to monitor processes on the machine.

This feature is completed, but yet not pushed. It will be available from version 1.0.11. Then the instances will be refreshed on every read.

Refreshing on every read could perhaps be a problem for large amount of counters with relatively high frequencies (in my tests I got about 850 counters with most of them every 5 secondes and I see it cousumes some cpu resources). Not sure the best option would be (every x read, not more than once a minute, ...).

I was considering every x reads since it would be very easy to implement. I can add that.

From version 1.0.11 it is possible to set the attribute named RefreshInstanceInterval on CounterGroup level.
