Symptoms

Observing the following behaviour where the scheduler for "ha_dg_target_summary" metric on the primary rac database target is disappearing

Restart EM agent (primary server) and run status agent scheduler for metric 'ha_dg_target_summary', we see metric scheduled

./emctl status agent scheduler |grep ha_dg_target_summary
2020-02-12 20:08:52.825 : rac_database:<TARGET_NAME1>:ha_dg_target_summary
2020-02-12 20:10:45.461 : rac_database:<TARGET_NAME2>:ha_dg_target_summary
2020-02-12 20:11:39.532 : rac_database:<TARGET_NAME3>:ha_dg_target_summary

After few minutes we see metric automatically disappeared from schedule

./emctl status agent scheduler |grep ha_dg_target_summary

<no output>

When restarting EM agent (primary server) and the scheduled metric is back

./emctl status agent scheduler |grep ha_dg_target_summary
2020-02-12 22:19:19.945 : rac_database:<TARGET_NAME1>:ha_dg_target_summary
2020-02-12 22:19:24.185 : rac_database:<TARGET_NAME2>:ha_dg_target_summary
