The performance of TESS is very slow, what performance parameters can be checked? How can the performance be improved?
If you find your CEM TESS (TIM Collector) to be performing slowly, check the following parameters and tune them to see if there is a performance improvement.
Check the size of CEMDB (APMDB). A large Postgres database size can cause a slow TESS (TIM Collector). if the database size is very large, run the manual Postgres Vacuum command to free up Postgres table space.
Increase the values of "Max-Fsm-Pages" in the postgres.conf file (/var/lib/pgsql/data/postgresql.conf )
Increase this setting to 24000000 and restart the database.
Check the following data retention settings on CEM and change to recommended values.
Once these changes are made, TESS (TIM Collector) will gradually start showing improved performance. If you still have performance issues, please contact CA APM Support by opening an issue at support.ca.com.
