How to access service bus queues metrics in Azure Metrics Exporter

Byna, Gayathri 0

I'm sending Azure metrics to Prometheus and setting up prometheus alerts. I'm able to send Azure Metrics for all Azure resources through resource id, but when trying to access Azure metrics for Service bus queues, i'm getting 400 error.

I'm using Robust Perception for Azure Metrics exporter.

Any suggestions on this topic will be really helpful.

Ensure that the resource_id for the Service Bus queue is correctly specified.

The resource_id format for Service Bus queues is:

/subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/Microsoft.ServiceBus/namespaces/{namespace-name}/queues/{queue-name}

Check your configuration in azure.yml. You should have something like:

resource_groups:

resource_group: "your-resource-group" resource_types:

"Microsoft.ServiceBus/namespaces"

metrics:

name: "Messages"

name: "ActiveMessages"

name: "DeadletteredMessages"

Make sure you have the correct permissions set up:

The service principal needs "Monitoring Reader" role

For Service Bus specifically, you might also need "Azure Service Bus Data Owner" or "Azure Service Bus Data Reader"

Verify the metrics you're trying to collect are available through the Azure Monitor API. Common Service Bus metrics include:

ActiveMessages

DeadletteredMessages

IncomingMessages

OutgoingMessages

ScheduledMessages

Hi Zafer,
Thanks for the reply, the azure.yml configuration is correct. I will cross verify the permissions.

Another question: In the Solution you mentioned,
resource_groups:

resource_group: "your-resource-group" resource_types:

"Microsoft.ServiceBus/namespaces"

metrics:

name: "Messages"

name: "ActiveMessages"

name: "DeadletteredMessages"

where do you apply the filter for EntityName?

I have the following configuration in azure.yml

targets:

resource: "resource-id" (ex: resourceGroups/{resource-group-name}/providers/Microsoft.ServiceBus/namespaces/{namespace-name}/queues/{queue-name})

metrics:

name: "Messages"

Hi,

The filter for EntityName can typically be applied within the azure.yml configuration under the metrics section by specifying the relevant dimensions or filters.

In your configuration, since you're specifying a resource directly (e.g., resource-id including the queue name), the metrics retrieved will already be scoped to that specific entity. If you need additional filtering (e.g., for specific entities like queues or topics within a namespace), ensure you use the dimensions provided by Azure Monitor for that metric.

For example:

metrics:

name: "Messages" dimensions:

name: "EntityName" value: "your-queue-name"

Hi,
I just tried adding dimensions to the azure.yml file, but im getting an error " Error parsing config file: unknown fields in config: dimensions"

Seems like dimensions is not being recognized.

Any other suggestions is really appreciated as I have been trying a lot on this topic.

Hi,
I just tried with configuration you mentioned above. I'm getting error as "Unknown fields: dimensions"

Seems like dimensions is not being recognized.

It seems the dimensions field might not be supported in your current configuration or setup.

Instead, if you are targeting specific entities like a queue or topic, you might need to ensure that the resource field includes the full path to the specific resource (e.g., queue or topic) you're monitoring. For example:

resource: "resourceGroups/{resource-group-name}/providers/Microsoft.ServiceBus/namespaces/{namespace-name}/queues/{queue-name}"

metrics:

name: "Messages"

This approach scopes the metrics directly to the specific entity without needing additional filters like dimensions.

If the issue persists, it might be worth reviewing the Azure Monitor or metric configuration documentation for the specific integration you are using.

Hi,

thanks, that doesn't work too. May be I should try a different configuration with different docker image and set up.
