Take control of your Microsoft MSMQ environments with Nodinite. This page guides you through remote queue management, threshold configuration, and secure administrative actions—designed to keep your integration landscape healthy, compliant, and efficient.
With Nodinite for MSMQ, you gain:
✅ Remote threshold management for queue depth, age, and quota
✅ Secure queue management—no direct Windows Server access required
✅ Administrative actions for public, private, and system queues
✅ Full auditing and compliance for all queue operations
Note
Manage monitoring thresholds and perform administrative remote actions on Microsoft MSMQ queues and services.
[!TIP] For information about how Nodinite monitors Microsoft MSMQ and evaluates queue states, see Monitoring Microsoft MSMQ.
Overview of MSMQ resources managed by Nodinite in a self-service enabled Monitor View.
Delegate management of MSMQ queues and services to your application management team and business users — without granting direct Windows Server access. Fewer privileged accounts means fewer attack vectors and lower risk of disruption to mission-critical services.
| Application Management Team | IT Operations | Business |
|---|---|---|
| Let your AM team resolve problems with content on MSMQ queues | Stay in complete control, end to end, with access to everything | Give your business self-service control for Servicebus resources |
Tip
All sensitive operations are Audit Logged, providing a complete, tamper-evident record of every queue action.
