Sample Use Case for Google Cloud Platform- Auto Remediation for GCP Instance

Here’s a sample workflow to demonstrate the use of the Orchestration app to automate remediation of GCP instance.

Executing self-healing workflows based on alerts coming from the monitoring tool(New Relic), to fix the problems through resetting the instance to its original state and making the GCP instance available. 

Assumptions

• New Relic alert profile must be integrated with Freshservice 

• Alert rules to tag the relevant instances. For this use case, we’re assigning the tags

  • P0_alert 

  • instance-1 

  • us-central1-a 
    
    

We’ll use these tags within the app action node to reset the correct instance.

Note: To integrate New Relic APM with Freshservice Alert Management, follow the documentation provided. 

Workflow configuration

1. Create the Event when an Incident is raised. Followed by a condition node to check whether the incident is p0 priority. 

2. You can then pull in the App Node which will have the following configurations:
   App Name: GCP - Orch

App Action: Reset Instance

Note while configuring inputs:

To specify the name and zone, we have to use liquid templates to map ticket tags and to fetch the appropriate value.

For example,

Placeholder for the name will be, 

 {% assign value = ticket.tags | split: ", " %}{{value[1]}}

Placeholder for the zone will be, 

{% assign value = ticket.tags | split: ", " %}{{value[2]}}

3. To validate whether the instance reset is successful or not a condition node is added with a check for status code as 200.

4. Finally, add a public note with a confirmation message
