Deleting Trace Log

Warning

SingleStore 9.0 gives you the opportunity to preview, evaluate, and provide feedback on new and upcoming features prior to their general availability. In the interim, SingleStore 8.9 is recommended for production workloads, which can later be upgraded to SingleStore 9.0.

Tracelog files can be very useful to understand the root cause of specific issues and troubleshoot them, so SingleStore recommends to keep a copy of these files within or outside of your cluster. However, you may safely delete the tracelog files should disk space utilization become a concern. If you are deleting tracelog files, make sure to send a kill -SIGHUP to the memsqld process.

Example:

ps -ef|grep memsql
memsql 2462 1 0 Jan15 ? 00:00:01 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld_safe --defaults-file /opt/memsql/Lf1/memsql.cnf --user 1008 --auto-restart StagedEnable 
memsql 2474 2462 19 Jan15 ? 8-08:46:41 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld --defaults-file /opt/memsql/Lf1/memsql.cnf --user 1008
memsql 2624 2474 0 Jan15 ? 00:00:00 /opt/singlestoredb-server-7.6.8-ad67e74046/memsqld --defaults-file /opt/memsql/Lf1 memsql.cnf --user 1008
