Re: getAverageGetTime/getAveragePutTime APIs of CacheMetrics always return 0

[Denis Magda]

Eventually I could reproduce your issue:
https://issues.apache.org/jira/browse/IGNITE-6966 


It will be fixed as a part of this endeavor:
https://cwiki.apache.org/confluence/display/IGNITE/IEP-6%3A+Metrics+improvements
 


Thanks for your patience and support in reproducing the bug.

Thanks for the example! Works fine when running IgniteMetricsExample#main
with the provided conf.

One difference to "my" configuration was that I was running the node
accessing the cache in client mode. 

If I start a node with the configuration provided in your example and then
run IgniteMetricsExample#main in client mode the statistics are 0.

Hi,

"Set CacheConfiguration.setStatisticsEnabled(boolean) to true for every
cache you want to collect the metrics for."

I've done that (see post from Nov 7).

"Pass a particular EventStorageSpi interface implementation into
IgniteConfiguration.setEventStorageSpi(...) method. You can use
MemoryEventStorageSpi provided out-of-the-box ."

Was hoping to get the metrics exposed via JMX to work.

Regards,
Per

Hi,

In addition to that you need to enable cache metrics calculation:
To enable cache metrics gathering:
Set CacheConfiguration.setStatisticsEnabled(boolean) to true for every cache 
you want to collect the metrics for.
Pass a particular EventStorageSpi interface implementation into 
IgniteConfiguration.setEventStorageSpi(...) method. You can use 
MemoryEventStorageSpi provided out-of-the-box .

Take from here: https://apacheignite.readme.io/v2.3/docs/cache-metrics

In the upcoming releases we plan to simplify cache metrics activation 
experience:

Hi,

Changed to 2.3.0 and added

Hi,

You need to enable metrics per data region 
(DataRegionConfiguration.setMetricsEnabled(true)). This is how it’s done in 
Ignite 2.3:
https://apacheignite.readme.io/docs 

If you prefer to stay on 2.2 then change the documentation version to see how 
to achieve this with the previous version.

Hi,

Using 2.2.0 and looking at the JMX stats, AverageGetTime and AveragePutTime
are always 0 (other stats, like CacheGets, are updated as expected)

Using cache configuration as:

Hello, BIren.

I think the impact on performance is minimal, but I don't have exact figures.

Thank you Pavel!!. I have not enabled statistics. Do you know what would be
performance impact on enabling it?

Hello, Biren.

Did you enable statistics in the cache configuration?

getAverageGetTime/getAveragePutTime APIs of CacheMetrics always return 0

[Biren]

We are investigating performance issue on our cluster of 2 nodes. We are
trying to understand time it takes to get or put a cache entry from/to the
cache. We are looking at out of box metrics for a cache . Both
getAverageGetTime and getAveragePutTime apis of CacheMetrics are always
giving value 0. 

Is this a bug or are we looking at wrong metric?
