On UCMDB server, thread dumps are created every minute. These files can be found under /hp/UCMDB/UCMDBServer/runtime/log
What is the reason that these thread dumps are getting created so frequently?
This is UCMDB functionality. It is working as per the design.
Logon to JMX Console ->Settings Services -> Run the method: showSettingsByCategory
Check the JVM settings
|Setting Name||Value||Default Value||Factory Value||Type||Is Global||Refresh Rate||Display in UI||Display Name||Description|
|jvm.thread.dump.log.rotate.time||60||60||60||number||Yes||Immediate||true||Log rotation time criteria||A time period (in seconds). Designates a period after which the log files in thread dump become obsolete and are zipped.|
|jvm.thread.dump.log.rotate.zip.cleanup.time||432000||432000||432000||number||Yes||Immediate||true||Log rotation zip cleanup time||A time period (in seconds) after which the zipped logs will become obsolete and will be removed from the file system.|
|jvm.thread.dump.timeout||30||30||30||number||Yes||Immediate||true||Thread Dump logging trigger time||A time period (in seconds) to trigger the thread dump|
|jvm.thread.dump.zip.freq||30||30||30||number||Yes||Immediate||true||Thread Dump zip rotation time period||A time period (in seconds) to trigger the thread dump zip rotation|
Thread dump files are generated depending on the setting jvm.thread.dump.timeout, and log files get zipped based on jvm.thread.dump.log.rotate.time which will be deleted by jvm.thread.dump.log.rotate.zip.cleanup.time.
If this frequency needs to be changed, use setSettingValue JMX method.
