Users monitoring IBM MQ on Mainframe (z/OS) systems via Piggyback encountered crashes and missing data following the changes in Werk #18303.
The following problems have been resolved:
Crash: "ValueError: Cannot render negative timespan": ibm_mq_queues check crashed with a ValueError when the IBM MQ system clock was ahead or due to parsing precision differences. Use absolute time difference to prevent negative timespans and crashes.
Data Merging: Users reported duplicate section definition errors or missing service details when monitoring Mainframe queues. The agent receives split information for QUEUE and QSTATUS.
The plugin now parses and merges QUEUE and QSTATUS outputs correctly. This merge combines the mq data into a single service. This resolves the crash and populates all metrics correctly.
Parsing of Empty Values: The parser now handles empty values in the agent output correctly. Previously, strict parsing logic led to incomplete data parsing or missing services.
Before this fix, you might have seen crashes in the ibm_mq_queues check or missing queue metrics. After updating, monitoring will be stable and complete without needing any changes to your configuration.
