Tag Filtering

[prsf1233]

Hi Jan, as discussed I would like to implement tag filtering on the AWS-EC2 dashboard. My end users do not know the InstanceId of their environment but I do tag each instance with a friendly name. I would like to be able to use the Name Tag for selecting the graphs rather than the InstanceId but so far have not been able to make it work. I can see the Tags but not been able to get the correct syntax.

Any suggestion on whether this is possible?

Thank you for idea and example. Tag filtering will be useful definitely. Let me investigate and test it.

[jangaraj]

There will be visualization problem with ec2_instance_attribute($region, Tags, {}) if EC2 instance has more than 1 tag, example:

I would like to have 1st variable (query) which will return all tags keys and then 2nd variable (query), which will return tags values based on selected tag key (1st variable). Is it possible?

Probably we need to wait for grafana/grafana#8307

[prsf1233]

Cool, for my use case only one Tag exists but yes I am sure others would need to filter on multple.

@prsf1233 Check out my comment on that PR: grafana/grafana#8307 (comment)

This is how I handle the 'friendly name' issue internally.

hi @jangaraj, i wanted to submit a branch and pr for this issue, but i obviously get a 403. how can i do this?

[jangaraj]

Hi @pax-awitt, that's correct. You can push the code only to the repos, where you have write permission. Please fork this repo first and then create the pull request based on your forked and modified repo. Github help can be the useful doc for you.

What about something like that: ec2_instance_attribute($region, Tags.Name, {}). I have checked it on 4.6.0 version.

[jangaraj]

@tomislater That's filtering is by one tag key (Name). It's OK for simple tagging. But it can be more complicated. For example, if you have blue/green deployment. Then the Name tag value is not unique and you need to filter by additional key (Colour) as well. The best general solution for the dashboard is to have ad-hoc filters similar to Elasticsearch ad-hoc filters:

Feel free to open feature/pull request for CloudWatch plugin. Some function, which will return all available tag keys and tag values in the selected AWS "space" (ec2, ebs, emr, ...) must be implemented.

If EC2 instances don't have a Name tags, then Tag Name: All and use classic Instance ID variable to select instance.

Hi,

We have imported latest change done by you but still not working.

[jangaraj]

It looks like a IAM problem in your case. Do you have:

"ec2:DescribeTags", "ec2:DescribeInstances"
