Number of consumer threads that the collector will create. By default, collector will create as many threads as there are consumers in the event hub.

Parameters marked as "Mandatory" are required for the collector's configuration. Optional parameters can be omitted or removed if not used, but they provide additional customization and control over the collector's behavior.

Event Hubs Tagging Configuration

Event Hubs supports multiple tagging parameters and formats to categorize and manage event data efficiently. Below are the configuration options for overriding, auto-categorizing, and extending tags.

The default configuration of the tag mapping can be found in this article.

Override tag

Advanced setting. Please consult to Devo support before use advanced tag map.

To customize the default tag behavior, users can configure the override_tag parameter within the Event Hub queue configuration. This parameter allows either a simple tag string or a more advanced tag mapping structure to be applied to all records.

The advanced tag map structure follows this format:

default_tag: A fallback tag applied to all records not matched by any tag_map entry.
tag_map: A list of tag entries, each containing a tag value and a JMESPath expression to match specific records.
jmespath_refs: Reference variables that can be used within JMESPath expressions in the tag_map. These act as reusable values within the tag map's matching logic.

override_tag:
 default_tag: "tag_value"
 tag_map:
 - tag: "tag_value"
 jmespath: "[?condition]"
 - tag: "tag_value"
 jmespath: "[?condition]"
 ...
 jmespath_refs:
 jmespath_ref_1: "{jmespath_expression_1}"
 jmespath_ref_2: "{jmespath_expression_2}"
 ...

"override_tag": {
 "default_tag": "tag_value",
 "tag_map": [
 {
 "tag": "tag_value",
 "jmespath": "[?condition]"
 },
 {
 "tag": "tag_value",
 "jmespath": "[?condition]"
 }
 .......
 ],
 "jmespath_refs": {
 "jmespath_ref_1": "{jmespath_expression_1}",
 "jmespath_ref_2": "{jmespath_expression_2}"
 }
 ........
 }

Auto-Category Tagging

From version 2.4 onwards, Auto Category is always enabled

Auto-category automatically appends pre-defined tags to the default tag (or the override_tag, if specified), enabling Azure events to be mapped dynamically to the appropriate Devo tag.

The system attempt to extract both the resource ID and the event category from the Azure event. If an event does not match any preconfigured tag mappings, it will be categorized under the following format: cloud.azure.{resource_id}.{category}.{queue_name}.

Auto-category tags are evaluated before the default or override tags.

Extend tag

Users can further customize tags by using the extend_tag parameter in the Event Hub queue configuration. This feature allows for the extension or updating of various tag properties. If override_tag is being used, the extend_tag will modify it; otherwise, it will extend the default tag.

The extend_tag parameter offers the following options:

default_tag: Replaces the existing default tag.
jmespath_refs: Adds or updates JMESPath substitution values.
tag_map: Adds or updates entries in the existing tag map. If an extend_tag entry matches an existing tag or JMESPath expression, that entry is replaced; otherwise, the new entry is appended.

Here is an example of extend_tag configuration:

Please note that the actual internal tag structure is not displayed in this guide as it is subject to change.

If the original, internal tag structure looks like this:

And the extend_tag configuration is applied, the resultant tag will be:

On Premise

The collector should not be run on premise.

Structure

The following directory structure will be required as part of the setup procedure (it can be created under any directory):

Devo credentials

In Devo, go to Administration → Credentials → X.509 Certificates, download the Certificate, Private key and Chain CA and save them in <any_directory>/devo-collectors/azure/certs. Learn more about security credentials in Devo here.

Editing the config.yaml file

In the config-azure.yaml file, replace the <app_id> , <active_directory_id>, <subscription_id> and <secret> values and enter the ones that you got in the previous steps. In the <short_unique_identifier> placeholder, enter the value that you choose.

Download the Docker image

The collector should be deployed as a Docker container. Download the Docker image of the collector as a .tgz file by clicking the link in the following table:
