Grouper Users - Open Discussion List

["Hyzer, Chris" <>]

I made a patch that has better grouper daemon specific logging.  This is a 
starting point.  Let me know what you think and if other things need to be 
logged or if things need not to be logged :)   Note, the threads that are 
involved in the loader make this complex, so I marked it as a high risk 
patch, though if you don't enable it, it shouldn't affect anything.  I am 
currently running this so I can see how it does.  Anyways, experimental at 
this point.

fixed in 2.3.0 api patch #77

https://spaces.internet2.edu/display/Grouper/Grouper+daemon+log

Note, if you are in an existing install, and you apply the patch, you need to 
add the two sections to the log4j.properties to enable this.

Thanks
Chris

Chad,

Thanks for the insights.

I will enable the two " grouper.app.loader.GrouperLoader [Config | Type ] " 
settings and see if those are more helpful.

My heartburn is that I think the other lines ( non ' session: start' ) are 
useful. But I appear to have to take 4 "bad lines" to get  1 "good one". ( 
Not a great trade off. And not clear as to why that is the current, default, 
condition.)
So I hate to lose the good to get rid of the bad. ( But it looks like I need 
to do that just to keep from filling up disks. :) )

Maybe the classes you pointed at will give me similar insights to what the 
loader is or is not doing. 
Thanks again.  ( I am still finding my way through the configuration and 
tuning.  I have a feeling that this will take a bit of time to polish....)

The default log4.properties has:

## Grouper Event Logging
## * Logs at _info_ only
log4j.logger.edu.internet2.middleware.grouper.log.EventLog        = INFO, 
grouper_event

We took that out for our loader. The log4j settings we currently have on our 
loader server are:

--------------------------
log4j.appender.R                           = org.apache.log4j.FileAppender
log4j.appender.R.File                       = ${log4j.filename.sync}
log4j.appender.R.layout                    = org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern  = %d{ISO8601}: [%t] %-5p 
%C{1}.%M(%L) - %m%n

log4j.rootLogger  = WARN, R

## All Internet2 (warn to grouper_error per default logger) 
log4j.logger.edu.internet2.middleware = WARN

log4j.logger.edu.internet2.middleware.grouper.RegistryInstall = INFO 

log4j.logger.edu.internet2.middleware.grouper.app.loader.GrouperLoaderType = 
DEBUG 

log4j.logger.edu.internet2.middleware.grouper.app.loader.GrouperLoaderConfig 
= DEBUG
--------------------------

The GrouperLoaderType DEBUG setting is pretty useful for summarizing some of 
the actual loader actions. The GrouperLoaderConfig DEBUG doesn't print out 
very much, just the LDAP settings periodically.

Maybe the EventLog logging of session starts can be changed to print at level 
debug instead of info? For a while, we had kept the level at info only in the 
UI, because there was no other way to see who was logging in. But we 
eventually turned it off in the UI as well, being too verbose.

Bump.

I am seeing 1G log files created per day.
        4721929 lines that have ' session: start'
        1153101 lines that do not.

That is 4.7M lines of logs that end up in our splunk system that provide no 
known useful information.

Does anyone else see this on their systems?
Does anyone use the Grouper Loader process? 

Any hints about how to make the logging better? ( Other than track down the 
line of code and wrapper it with an if block. )

questionable value....

I am trying to use the Loader process to sync some data into grouper from 
LDAP. ( That part is working as far as I can tell after I gave it enough ram 
to not fall over. :) )


However, in the grouper_error.log (for where the loader is logging) I am 
seeing a lot of lines like :
"
2017-08-16 14:25:04,783: [DefaultQuartzScheduler_Worker-7] INFO  
EventLog.info(156) -  - [9a3e8...c35b,'GrouperSystem','application'] session: 
start (0ms) "

And by a lot I mean ( Just from today's file...): 

$ wc -l grouper_error.log ; grep -c ' session: start' grouper_error.log; grep 
-vc ' session: start' grouper_error.log;
3135034 grouper_error.log  ( Total lines in the file)
2379686   ( Lines that are ' session: start' lines, 75% of the file!)
 755517    ( Lines that are not ' session: start' lines )

Can anyone tell me how to suppress ONLY those lines?
        I might be wrong but other lines that say things like "add member" , 
"delete member" (etc...) look like they are being logged from the same 
location. [ AKA: " INFO  EventLog.info(156)" ]

Could any explain why those log statements are there?
        I really don't understand what they are trying to communicate.
