zOS Agent Health dashboard

zDC CPU

This dashlet shows the zDataCollector (zDC) CPU usage, which is an aggregated measure of zDC and zLocalAgent CPU consumption. Typically, the CPU usage reflects the amount of work the zDC needs to manage the performance data generated by the underlying connected agents.

Connected CICS and IMS Agents

This dashlet shows the number of CICS and IMS agents connected to a zRemoteAgent. In steady state this measure should remain constant. A reduction or lack of the connected agents may indicate a connection problem due to:

  • zDC - zRemoteAgent connection
  • "CICS Transaction Server" sensor configuration
  • "IMS Control Region" and "IMS Application Region" sensor configuation

zDC - Dropped Buffer

This dashlet shows the total number of buffers unavailable for performance data processing in zDataCollector (zDC). The total buffer (shortage) count is an aggregate measure of SMO and Transaction buffers that are unavailable for zDC. Buffer shortage in zDC would cause missing or incomplete purepaths. This metric could be used for "Capacity Planning" related to:

  • SMO or Transaction Buffer count being small for the workload
  • Network Performance issues - network delays can cause event messages take longer time to get to the zRemoteAgent / Collector / Server
  • zDC CPU contention
  • zDC ZIIP contention
  • Excessive SubAgent event messages than the system capacity

zRemoteAgent CPU

This dashlet shows the CPU percentage used by zRemoteAgent per core/CPU. The CPU usage reflects the amount of work the zRA needs to process the performance data received from zDataCollector.

zRemoteAgent - Data Received

This dashlet shows the performance data received by zRemoteAgent from zDataCollector. This metric is measured in KB/Second.

SubPaths by zRemoteAgent

This dashlet shows the total number of subpaths (Start-Path events) processed by each zRemoteAgent.

DLI Calls by zRemoteAgent

This dashlet shows the total number of DLI calls processed by CICS/IMS Agents connected to each zRemoteAgent.

MQ API Calls by zRemoteAgent

This dashlet shows the total number of MQ API calls processed by CICS/IMS Agents connected to each zRemoteAgent.

DB2 SQL Calls by zRemoteAgent

This dashlet shows the total number of DB2 SQL calls processed by CICS Agents connected to each zRemoteAgent.
