Error description
PROBLEM DESCRIPTION: The MIRROR Tivoli Enterprise Monitoring Server will exhibit a spike in CPU utilization every three (3) minutes. The duration of the spike increases over time until the TEMS performance is impacted servicing its functionality RECREATE INSTRUCTIONS: 1. Install two (2) TEMS with FTO enabled. 2. Install OS Agent on endpoint 3. Add 623 FP2 UM Agent to HUB TEMS Depot 4. Execute 100 tacmd updateAgent -t UM -v 062302000 -n <endpoint:LZ> 5. Monitor CPU utilization of Backup HUB. 6. Observe duration of CPU Utilization increases every three (3) minutes over 1 hour time.
Local fix
1. Apply workaround solution IZ52198 supplied by IBM Support to RTEMS, HUB and MIRROR TEMS. 2. Enable automated cleardeploystatus capability for 1 hour intervals.
Problem summary
The mirror monitoring server will exhibit a spike in CPU utilization every three (3) minutes. The duration of the spike increases over time until the monitoring server's ability to function normally is impacted. The algorithm that executes on the mirror monitoring server acquires the list of deploy transactions contained on each remote monitoring server from the hub monitoring server every three minutes. The algorithm incorrectly treats the hub monitoring server as a remote and includes the deploy transactions from the hub in its list. As a result, the number of deploy transactions that are evaluated every three minutes doubles in size and takes increasing CPU cycles to process.
Problem conclusion
Revise the algorithm processing on the mirror monitoring server to exclude the hub monitoring server from its list. The fix for this APAR is contained in the following maintenance packages: | fix pack | 6.2.3-TIV-ITM-FP0005
Temporary fix
Execute the tacmd cleardeploystatus command frequently to reduce the number of deploy transactions that are on the list.
