Reset JMX counters for monitoring without restarting
Hi,
I am putting together some montitors for various things.
The counters seem to be ... from the beginning of the process.
This makes many of them not so useful for long term monitoring and alerting.
Is there a way to rest the counters without restarting solr or reloading a
core?
For instance: these seem to be from the time the process started.
java -jar /opt/scripts/pkg/cmdline-jmxclient-0.10.3.jar - localhost:9010
solr/collection1:id=org.apache.solr.handler.component.SearchHandler,type=/select
$NAME
avgTimePerRequest.value 363.66010984870064
medianRequestTime.value 1240.4161144999998
75thPcRequestTime.value 1614.2324915
95thPcRequestTime.value 3048.378881099999
99thPcRequestTime.value 5930.183086690001

In cloud mode, using CoreAdmin (which is how you reload a core) is not
recommended at all. The entire collection (all cores) can be reloaded
with the Collections API, and that is how it should be done.

Thanks,
I was hoping there was a way without a core reload.
Do you know what is different with cloud? I need to do this in both.

Some of the information you find in statistics might indeed go back to
the last Solr start.
The specific stats that you have indicated are most useful over a long
period of time, ideally for the entire time Solr has been running, but
if you do want to reset them, you can do so with a core reload. If
you're running cloud (doesn't look like you are), then you would reload
the whole collection, probably not the core.
Thanks,
Shawn

Hi Jeff,
With info that Solr provides in JMX you have to keep track of things
yourself, do subtractions and counting yourself.
If you don't feel like reinventing that, see
