Filebeat Azure Module Issue

willemdh · January 16, 2020, 10:49am

Hello,

We seem to have issues getting the Filebeat Azure module to connect to our configured Azure namespace. Filebeat version is 7.5.1.

Filebeat logs:

We have no idea why it doesn't want to connect to mynamespace.servicebus.windows.net:443

Filebeat configuration:

- module: azure
  activitylogs:
    enabled: true
    var:
      namespace: "mynamespace.servicebus.windows.net:443"
      eventhub: "Activitylog"
      consumer_group: "dgfilebeat"
      connection_string: "Endpoint=sb://mynamspace.servicebus.windows.net/;SharedAccessKeyName=ActivityLog;SharedAccessKey=mykey;EntityPath=activitylog"

Hi! Just to confirm, I notice what looks like a typo in your connection string (mynamspace instead of mynamespace)... is that a real configuration typo, or just a placeholder for the sake of public posts?

Otherwise, I notice the namespace field which shouldn't be needed here: this module only requires eventhub and connection_string (and optionally consumer_group). Also, your connection string looks potentially wrong, see this description -- you shouldn't have an EntityPath at the end, as that should be added by the module itself based on the value of the eventhub field.

Hopefully one of those things will help If not feel free to follow up with more details.

Thanks for the fast response, the mynamespace is indeed just a placeholder. I'll look asap into your other suggestions. Could be Monday. Grtz

Hey Fae,

Tried some of your suggestions, but the problem remains the same.

You say

"I notice the namespace field which shouldn't be needed here: this module only requires eventhub and connection_string (and optionally consumer_group )"

But the docs say:

- module: azure
  activitylogs:
    enabled: true
    var:
      namespace: "obseventhubs.servicebus.windows.net:9093"
      eventhub: ["insights-operational-logs"]
      consumer_group: "$Default"
      connection_string: ""

We created a custom consumer_group for Filebeat, called dgfilebeat.

I removed the EntityPath and restarted Filebeat, but I get the same issue.

- module: azure
  activitylogs:
    enabled: true
    var:
#      namespace: "mynamespace.servicebus.windows.net:443"
      eventhub: "Activitylog"
      consumer_group: "mynamespace"
      connection_string: "Endpoint=sb://mynamespace.servicebus.windows.net:443;SharedAccessKeyName=ActivityLog;SharedAccessKey=myaccesskey"

Results in:

Checked our perimeter firewall and we do not see anything blocked / denied.

Hey Fae,

Just got it working. We mistakenly assumed we could choose a port and as we have other stuff connecting to Azure over 443,we also set this in the namespace.

So it does work with:

namespace: "mynamespace.servicebus.windows.net:9093"

Found in https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-faq
that Kafka is only accessible over 9093. Maybe interesting to mention this in https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-module-azure.html#_module_configuration?

Grtz

Willem
