Monitoring, Logging, and Troubleshooting
Monitoring, logging, and troubleshooting
This domain tests how you find and prove the cause of a runtime problem in ACE. The main tools are the event log, administration log, service trace, user trace, monitoring events, and statistics or accounting data. The exam rewards a deliberate evidence sequence, not random restarts.
Core rules
- Start with the event log and the BIP message number. The text explains the condition; the inserts identify the flow, node, or resource.
- Service trace records internal processing and is enabled for a server or flow at a trace level. User trace records flow-level activity. Both add overhead, so enable them narrowly and disable them afterward.
- Monitoring events are configured through a monitoring profile and can publish business or operational data for dashboards and SLAs. They are not a replacement for debug trace.
- Statistics and accounting data show throughput, elapsed time, and resource use; use them to distinguish a functional failure from a performance problem.
- The activity log can show the path and state of a transaction across flows and resources.
Worked example
An intermittent flow fails only under load. Check the event log first for connection-pool or timeout BIP messages. Enable service trace at debug level for that integration server and flow, reproduce with a small load, read the trace, then disable it. If the trace shows pool exhaustion, raise the pool size in policy or server configuration and confirm with statistics that elapsed time falls. Record the BIP code and correlation ID in the incident notes.
Traps
Leaving debug trace enabled degrades performance and fills logs. Confusing user trace with service trace sends you to the wrong file. Restarting before capturing evidence destroys the state you need. Treating a monitoring event as an error log misses the actual exception.
