Render Alertmanager templates locally

Normally to test Alertmanager templates you need to restart running Alertmanager and wait for alerts to arrive to Slack or email. To speed up this process parts of templates could be rendered locally using predefined alerts data without the need of the actual Alertmanager.

What you still need in this case is amtool which is a part of Alertmanager delivery which could be downloaded here https://github.com/prometheus/alertmanager/releases

Some examples of templates rendering:

# navigate to the templates dir

Set GOPRIVATE to match your github organization

I keep fixing this up, but if it fails for you, check if these are better maintained https://tip.golang.org/cmd/go/#hdr-Configuration_for_downloading_non_public_code and https://golang.org/ref/mod#private-modules.

Cloning the repo using one of the below techniques should work correctly but you may still be getting an unrecognized import error.

As it stands for Go v1.13, I found in the doc that we should use the GOPRIVATE variable like so:

GOPRIVATE=github.com/ORGANISATION_OR_USER_NAME go get -u -f github.com/ORGANISATION_OR_USER_NAME/REPO_NAME

The 'go env -w' command (see 'go help env') can be used to set these variables for future go command invocations.

Intro

So your dashboard is slow? We are doing our best but maybe it's time to think if the issue isn't on your side.

Some of our dashboards looks like https://www.theworldsworstwebsiteever.com/. Are you sure you really need to see all the time all the data? Or do you really need to see data for last week or month all the time? How often do you use filtering by some of those variables in your dashboard?

Let's not end up as your mother saying:

But.. but.. I might need this in future so let's leave this icon on the Desktop.
