petascope NioEventLoop TRACE logs

[Dimitar Misev]

The startup log can be improved, here's a suggestion: ​https://www.diffchecker.com/K2KSwtdk

Below, 66 what? ms? I would word it as rasql query executed in 66 ms.

 DEBUG [11:42:46] RasUtil@229: Total time for rasql: 66

Here I see three identical logs for the rasql query basically. Only one is enough (RasUtil@142 I guess), the others should be removed:

 DEBUG [11:42:49] KVPWCSProcessCoverageHandler@114: Executing rasql query: SELECT encode(c[0:885,0:710], "png" , "{\"geoReference\":{\"crs\":\"EPSG:4326\",\"bbox\":{\"xmin\":111.975,\"ymin\":-44.525,\"xmax\":156.275,\"ymax\":-8.975}
}}") FROM test_mean_summer_airtemp AS c

er_airtemp AS c'.

There are too many of these logs, they should be blocked somehow (e.g. configure properly log4j of the libraries used in petascope):

 TRACE [11:42:49] NioEventLoop@46: instrumented a special java.util.Set into: sun.nio.ch.EPollSelectorImpl@771e28cb
 ...
 DEBUG [11:42:49] PoolThreadCache@81: Freed 1 thread-local buffer(s) from thread: threadDeathWatcher-3-2

There's duplication about the 'coverage id read from cache' (I think that log statement could be completely removed, it's not very useful at all):

 DEBUG [11:42:50] PetascopeController@90: Received request: coverageId=test_mean_summer_airtemp&format=image/png&request=GetCoverage&service=WCS&version=2.0.1
 DEBUG [11:42:50] AbstractHandler@90: Found the request handler: petascope.controller.handler.service.KVPWCSServiceHandler

This should not be INFO:

  INFO [11:40:17] TypeRegistry@202: Succesfully initiated the type registry. Contents: {RGBSet...

best split it like this (notice also some fixed typos!):

  INFO [11:40:17] TypeRegistry@202: Successfully initialized the type registry. 
  TRACE [11:40:17] TypeRegistry@202: Contents: {RGBSet...
