Re: Cache stats like number of cache hits, misses, reads, write, avg

[aealexsandrov]

Hi,

DataStreamer depends on the allowOverwrite flag.

https://apacheignite.readme.io/docs/data-streamers#section-allow-overwrite

The default value is false to get the best performance. But it also means
that metrics will not be updated.

If you set allowOverwrite true then data streamer will work similar to usual
cache operation and metrics should work fine in this case.

BR,
Andrei

HI Andrei 

It worked after enabling metrics at both egionCfg and storageCfg and also
enabling cacheMetrics for the cache. 

Stats are getting captured when we insert it thru cache.Put/putall , not
getting captured the data inserted thru datastreamer

| CustomerCharsCache(@c11)| PARTITIONED | 6 | min: 5849433
(0 / 5849433)| min: 0   | min: 21 | min: 21  | min:
12891798|
| | |   | avg:
6789912.00 (0.00 / 6789912.00)   | avg: 0.00| avg: 47.17  | avg: 47.17  
| avg: 13579824.00 |
| | |   | max: 7441242
(0 / 7441242)| max: 0   | max: 79 | max: 79  | max:
14560907|

Below cache, we have inserted data thru data streamer, we dont see any stats
below

 CustomerEntCache(@c12)  | PARTITIONED | 6 | min: 85799090
(0 / 85799090)  | min: 0   | min: 0  | min: 0   | min: 0

| | |   | avg:

| avg: 0.00|
| | |   | max: 109158877
(0 / 109158877)| max: 0   | max: 0  | max: 0   | max: 0 
 
|
+-+-+---+---+--+-+--+--+

Also, we are using a cache-template like below, here I was trying to enable
cacheMetrics like below

 

**









Applying this template while definiting the cache like below, but still
statistics are not enables for cache.


 




So I had to add this to each cache to enable statistics at cache level. Cant
we just add it to the template and use this template where you need this
setting enabled.

Thanks

I guess I was doing the same.
Only change I could see is, you were enabling setMetrcis for both regionCfg
and storageCng

   regionCfg.setMetricsEnabled(true);
// Setting the data region configuration.
storageCfg.setDataRegionConfigurations(regionCfg);
storageCfg.setMetricsEnabled(true);

I have attached, wont be able to upload the files..

But here the content, server-config.xml we use to start the Ignite node
Begin serve XML ===

Hi,

I tested that it works. I attached my code for the server node and
configuration for the visor.

Could you please check it?

startActivate.java
  
default-config.xml
  

Run main class from startActivate.java and  visor cmd with provided config.
As a result I see:

visor> cache -c=cacheNam -a

  Total number of executions: 0
  Total number of failures:   0

Please check it and if it will work then try to check your config (or attach
it as a XML file because you provide only part of it).

BR,
Andrei
