how to limit collector-gc.log creation under /var/log/ambari-metrics-collector

mike_bronson7 — Wed, 15 Aug 2018 14:59:41 GMT

Under ambari-metrics-collector we have many files as ollector-gc.log

how to limit the number of this files to 5 max ?

as I know we can set the follwing syntax in ambari configuration ( I guess ams-env )

-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=4K

but I am not sure on which variable in ams-env we can set it ?

/var/log/ambari-metrics-collector

Hi @Michael Bronson ,

Adding the below parameters for AMS_COLLECTOR_GC_OPTS in ams-env template and SERVER_GC_OPTS in ams-hbase-env template via ambari

-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=4K

Helped me.

I hope this is your query.

you might need to add it in this two places to control collector-gc.log and gc.log

Hope this helps.

can I add the syntax on the end of the line - so the final line should be like this ?

export AMS_COLLECTOR_GC_OPTS="-XX:+UseConcMarkSweepGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:{{ams_collector_log_dir}}/collector-gc.log-`date +'%Y%m%d%H%M'` -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=4K"
