- Browse messages to diagnose processing failures—view message conte
🧹 Remote Queue Management
- Purge test queues after failed test runs—remove thousands of messages with one click instead of manual MQ Explorer purge
- Browse messages to diagnose processing failures—view message content, headers, properties without altering queue
- Clear dead letter queue after identifying undeliverable messages—prevents DLQ disk space exhaustion
- Edit queue thresholds based on observed traffic patterns—adjust depth/age limits without queue manager restart
Example: After test run generates 5,000 junk messages in TEST.ORDERS queue, tester purges queue via Nodinite web interface in 10 seconds vs. opening MQ Explorer, connecting to queue manager, navigating to queue, selecting messages, confirming purge.
Complete Feature Reference
The IBM MQ Monitoring Agent provides comprehensive monitoring across six IBM MQ resource types—each with specialized capabilities for alerts, metrics, and remote actions:
| MQ Resource | Monitors | Remote Actions | Key Features |
|---|---|---|---|
| [Monitoring queues][] | Queue depth (current/max), oldest message age, input/output counts | Clear queue · Browse messages · Edit thresholds | Prevent backlogs and aging messages; monitor local, remote, and alias queues |
| [Monitoring channels][] | Channel state (running/stopped/retrying), message count, status | View details · Edit monitoring | Track sender/receiver/server/cluster channels; detect connectivity failures |
| [Monitoring listeners][] | Listener state (running/stopped), protocol, port | View details · Edit monitoring | Ensure queue manager accepts connections; monitor TCP, LU62, NetBIOS listeners |
| [Monitoring client connections][] | Active connections, client identifiers, channel name | View details · Edit monitoring | Track application connectivity; identify connection leaks |
| [Monitoring queue managers][] | Queue manager status, uptime, resource availability | View details · Edit monitoring | Overall health of queue manager instances |
| [Managing IBM MQ][] | Remote queue management and operations | Purge queues · Browse messages · Clear DLQ | Delegate control without MQ Explorer access |
Note
One License, Unlimited Queue Managers: Monitor all your IBM MQ environments (on-premises, cloud, z/OS) with a single Nodinite license—no per-queue-manager fees.
Get Started
| Step | Task | Description |
|---|---|---|
| 1 | [Review Prerequisites][Prerequisites] | Confirm IBM MQ client libraries, network connectivity to queue managers, MQ user credentials with appropriate permissions (mqm group or equivalent), SSL/TLS certificates (if using secure channels). |
| 2 | [Install the Agent][Installation] | Download the IBM MQ Monitoring Agent installer, run on Windows Server or Linux, configure queue manager connection details (host, port, channel name, queue manager name), and register with Nodinite Core Services. |
| 3 | Configure Monitored Resources | Add queue managers as [Resources][], configure queue monitoring (depth and age thresholds), channel monitoring (state alerts), listener monitoring, client connection tracking based on business needs. |
| 4 | Set Up Alerts | Define alert thresholds (queue depth >500 messages, message age >30 minutes, channel STOPPED/RETRYING, listener STOPPED); configure notification channels (email, Teams, ticketing systems). |
| 5 | Create Dashboards | Build custom dashboards in Nodinite [Web Client][] showing queue depth trends, message age heatmaps, channel status overview, dead letter queue growth—tailored for MQ admins, operations, and application teams. |
| 6 | Delegate Access | Use [Role][Roles]-based access to grant operations teams permission to view [Monitor Views][], purge queues, browse messages—without granting mqm group membership or MQ Explorer access. Full audit trails log all actions. |
Common Questions
Q: Do I need to install IBM MQ server on the monitoring agent host? A: No. The IBM MQ Monitoring Agent only requires IBM MQ client libraries (not full MQ server installation). Install MQ client, configure connection details (queue manager name, host, port, channel), and the agent monitors remotely via MQ client-server protocol.
Q: Can I monitor multiple queue managers from one agent? A: Yes. A single IBM MQ Monitoring Agent can monitor unlimited queue managers—on-premises, cloud (IBM Cloud, AWS MQ, Azure), z/OS, distributed platforms. Configure each queue manager as a separate [Resource][] with its own connection details and credentials.
Q: What permissions are required to monitor IBM MQ? A: Minimum: Read-only access to queue manager (DISPLAY authority for queues, channels, listeners). For remote actions (purge queues, clear messages): CHANGE authority. For full management: mqm group membership. See [Prerequisites][] for detailed permission requirements per feature.
Q: How do I monitor MQ over SSL/TLS connections? A: The agent supports SSL/TLS for secure queue manager connections. Configure SSL certificate keystore, specify cipher suite in channel definition, and provide SSL configuration in agent settings. See [Prerequisites][] for SSL/TLS setup guidance.
Q: Can I monitor IBM MQ on z/OS mainframe? A: Yes. The agent connects to z/OS queue managers using MQ client-server protocol (same as distributed platforms). Configure z/OS queue manager name, host, port, and SVRCONN channel—agent monitors queues, channels, and listeners regardless of platform.
Q: How do I prevent alerts for temporary queue depth spikes? A: Configure per-queue thresholds with appropriate limits for each queue's normal operating range. High-volume queues can have higher thresholds (e.g., alert if depth >5,000) while error queues have strict thresholds (e.g., alert if depth >10). Adjust thresholds based on historical queue depth patterns.
Q: What happens if the agent loses connectivity to a queue manager? A: The agent detects connectivity failure during next monitoring cycle, marks the queue manager resource as "Error" with connectivity failure message, and triggers alerts. When connectivity restored, agent resumes normal monitoring automatically—no manual intervention required.
Q: Can I monitor the SYSTEM.DEAD.LETTER.QUEUE? A: Yes—treat dead letter queue like any other queue. Monitor depth and message age with strict thresholds (e.g., alert if DLQ depth >0 or >5 messages). Undeliverable messages in DLQ indicate delivery failures requiring investigation—proactive DLQ monitoring prevents silent message loss.
Q: How do I grant operations teams access to clear queues without MQ Explorer? A: Use Nodinite [Roles][] to define permissions (e.g., "MQ Operations" role can purge test queues, browse production queues). Assign users to roles, create [Monitor Views][] filtered to approved queues—users perform actions from [Web Client][] with full audit trails, no MQ Explorer or mqm group membership required.
Q: Can I visualize queue depth trends over time? A: Yes. Queue depth metrics are stored in Nodinite [Resources][] with timestamps. Build dashboards showing queue depth trends (hourly/daily/weekly), message age heatmaps, peak depth periods. Export metrics via [Web API][] to Power BI [Reports][] for advanced analytics.
