You register your targets with a target group and each target group is used to route requests to one or more registered targets. By default, the load balancer sends requests to registered targets using the port and protocol that you specified for the target group. You can override this port when you register each target with the target group.
Use OpsRamp AWS Public Cloud Integration to discover and collect metrics against the AWS Target Group.
Setup
To set up the AWS integration and discover the Target Group resources, do the following:
Create an AWS Integration if not available in your installed integrations. For more information on how to install the AWS Integration, refer to AWS Resources.
Create a discovery profile. For more information on how to create a discovery profile, refer to Create Discovery Profile.
Select
Target Groupunder the Filter Criteria in the Edit Discovery Profile page.
AWS Integration Discovery Profile
Save the discovery profile to make them available in the list of Discovery Profiles.
Scan to discover the resources at any time independent of the predefined schedule.
Once the scan is completed, you can view the Target Group resources under Infrastructure > Resources > AWS category.
- Create a template with collector type Google and applicable for Interconnect. See Create a Template for more information on how to create a template.
- Refer to Assign a Template on how to assign a template to a resource.
- Click the Metrics tab to view the monitoring data of the Target Group as shown below:
Event support
CloudTrail Event support
OpsRamp supports AWS Cloud trail events for the Target Group [CreateTargetGroup, DeleteTargetGroup]. Configure Stream CloudTrail messages in Opsramp AWS integration discovery profile.
CloudWatch Alarm support
OpsRamp supports AWS Cloud Watch Alarms for the Target Group.
