Overview

Motadata AIOps introduces rule-based tagging, a feature designed to automate the assignment and removal of tags across various monitored entities, including Monitors, VMs, Applications, Processes, Services, IP SLA, and Interfaces. This functionality eliminates the manual effort traditionally required for tag management.

Rule-based tagging supports the application of static tags, key-value pair tags, and dynamic tags. Furthermore, it allows mulitple metric counter-based conditions. These conditions enable the precise application or removal of tags based on specific performance metrics, ensuring tags are applied only to devices that meet the defined criteria.

Navigation

Go to Menu. Select System Settings . After that, select Rule Based Tags. The configuration page for Rule Based Tags is now displayed.

Rule Based Tags Screen

You shall be able to view all the configured rules for tagging on this screen. Below is a gist for all the fields available:

Field	Description
Rule Name	Name of the rule.
Description	Description can contain either the purpose of the rule, types of devices it applies the tag
Operation	Displays if the rule is being used to assign or remove tags.
Used Count	The Used Count column will display the total number of devices which are associated with the rule.
Tag	This column will display the tag which will be assigned or removed using the particular rule.
Last Ran At	Displays the timestamp of when the rule was executed.
Actions	Below are the actions available for a rule: - Click on to execute the rule manually. - Click on and select Delete Rule to remove the specifc Rule.

note

Deleting a Rule will not remove all the Tags that have been applied using the specific rule. In order to remove the tags associated with the deleted rule, you will need to create a new rule to remove the tags.

Create a Rule

Click on the Create Rule option in the top right of the screen to start creating your custom Rule to automatically tag the devices. On the Create Rule screen, below configuration options will be available:

Field	Description
Rule Name	Enter the name of the rule.
Description	Enter information to explain the purpose of the rule or mention on what devices it will applicable.
Rule Applies to	Select a type of device using the monitor.
Tag Operation	Select Assign or Remove opeartion to perform the respective action using the rule.
Key	Specify the tag you want to assign. You can choose to a define a standalone tag or a key-value pair based tag. In case you are defining a key-value pair based tag, populate the value field as well.
Value	Value field allows to define static and dynamic tags. Mention the tag to define a static value. For dynamic tags, mention the counter name inside curly brackets {} (refer to the note below).
Condition	Check Configuring Condition section to know more about it.

note

To define a dynamic tag, mention the complete counter name inside the curly brackets {}. (For e.g. {instance.type})

Configuring Condition

You can specify multiple conditions based on metric counters that will ensure the filters are assigned or removed when the conditions are met. The condition block allows you to define multiple conditions.

Since there are multiple parameters that you can set, let's look at them individually:

Field	Description
Group Matching	This option will help you define if you want to include or exclude the devices matching the condition you have defined. Below is a gist: - Include: When selected, will include all the devices that match the defined condition. - Exclude: When selected, will exclude all the devices that match the defined conditions.
Counter	Mention the metric counter you want to set as the condition.
Operator	Select an operator from the dropdown.
Value	Enter the value that you want to equate against the metric counter.
AND/OR	This option will help you define intra-condition operation. Below is gist of the available options: - AND: When selected, tag will only apply to the devices satisfying both the conditions. - OR: When selected, tag will only apply to the devices satisfying either of the conditions.

Click on to add more conditions.

Rule Criteria

Rule Criteria will display the Rule Condition query in raw format in real-time. It will help you understand how the query is formed and executed in the backend.

• Click on Create Rule to apply the configuration and save.
• Click on Preview to see the list of devices that qualify for the defined rule condition.
• Click on Reset to clear all fields and start afresh.

Use-Case

For instance, you want to assign a Tag Environment:Prod to monitor having type as Linux that contains prod in its name. Let's understand the configuration required to achieve the above scenario.

Once you have provided the Rule name and description, ensure you select Monitor under the Rule applies to dropdown. The next step would be to choose Assign Tag under the Tag Operation field.

After that, mention Environment in the Key field and Prod in the Value field.

Now, the conditions will need to be configured to assign the tags only to Linux monitors containing prod in its name.

Select Include operation for Group Matching. Then, select object.type using the Counter field and choose Contains in the Operator dropdown. Finally, enter Linux in the Value.

Click on to add one more condition. Then select AND operator between two conditions.

Now, select object.name using the Counter dropdown and choose Contains as the Operator. Then, enter prod as Value.

You shall also be able to see the generated query under the Rule Criteria section.

Click on Preview to view the list of devices qualifying for the rule.

Click on Create Rule to apply and save the configuration.
