RabbitMQ - Disk
The Nodinite RabbitMQ Monitoring Agent monitors the RabbitMQ disk usage on all configured Brokers.
- The Disk usage for RabbitMQ Brokers is listed in Nodinite as a resource where the name of the resource is
ClusterName@NodeName- 1 Resource per node in the cluster
- The
DiskResource Application name is associated with the name from the Display name property set by the Configuration - The Disk Resource is grouped by the Category Disk
Example of a Monitor View filtered by the 'Disk' category
What are the key features for Monitoring the RabbitMQ disk?
- Cluster support - Verifies that your disk usage for each node within the cluster is within user-defined thresholds
- Remote Actions - Support the execution of user-initiated remote actions
- State Evaluation - Monitors and evaluates the run-time state
What is evaluated for the RabbitMQ Disk usage?
The evaluation rules for Disk usage are provided in the table below:
| State | Status | Description | Actions | |
|---|---|---|---|---|
| Unavailable | Resource not available | Evaluation of the 'RabbitMQ Disk' is not possible either due to network or security-related problems | Review prerequisites | |
| Error | Disk usage error threshold is breached | If the used disk is above the user-defined Error usage threshold | Edit | |
| Warning | Disk usage warning threshold is breached | If the used disk is above the user-defined Warning usage threshold | Edit | |
| OK | Online | Disk usage is below user-defined thresholds, and no other problems are detected | Edit |
TIP: The evaluated state may be reconfigured using the Expected State functionality that exists on every Resource within Nodinite.
Disk Configuration
Actions
The Nodinite RabbitMQ Agent has support for Remote Actions. The following Actions are currently implemented for monitoring disk usage:
- Edit - Edit user-defined disk usage thresholds
Edit
It is possible to configure a specific evaluation for a certain RabbitMQ node. The specific evaluation has precedence over the global disk evaluation. The same options are available as in remote configuration for the disk.
You can manage the following properties:
- Description
The following dialogue is displayed when you select the Edit option from the 'Actions' button menu item:
Here it is possible to configure a specific evaluation for a certain node. The evaluation has precedence over the global settings. The same set of options are available as in the remote configuration for the disk.
Description
You can manage the user-friendly Description. This setting is unique for each node.
Disk usage
You can manage the thresholds for:
- Warning
- Error
- Evaluation Type
- None
- Fixed
None
Select the None evaluation type, to Disable Monitoring of the disk usage on the selected RabbitMQ node.
Fixed
Select the Fixed evaluation type to use an integer for monitoring the number of messages on the queue.
- Warning - The minimum free disk space before the RabbitMQ disk limit is reached and a Warning alert is triggered. E.g. RabbitMQ disk limit is 5GB, and the Warning Limit is 2GB will trigger the Warning alert when less then 7GB is free
- Error - The minimum of free memory before the RabbitMQ memory limit is reached and an Error alert is triggered. E.g. the RabbitMQ memory limit is 6GB, and the Error Limit is 1GB will trigger the Error alert when more then 5GB memory is in use
Save
You must click Save or click Save and close, for changes to be persisted. The new settings/thresholds are evaluated on the next synchronisation.
NOTE: Depending on the synchronisation interval set for the agent, there might be a delay before the Web Client reflects upon the change. You can choose to force the agent to synchronize from the configuration of the Monitoring Agents.
Save and close, save, and close the dialogue.
Cancel, close the dialogue without saving any changes.
