Support description annotation which is used by newer alerts

[runningman84]

I am not 100% sure if this works please double check...

The current template lacks description support and the duration could also be hidden if there is no end date? In my tests it is "-" until the event is solved.

Thanks for taking a look at this. Maybe for completeness we could also add summary too?

It was summary & description in Prometheus for a fair amount of time then we pivoted towards simply using message, as summary and description more than often were super similar.

[runningman84]

I have added the summary too...

Btw. do you know why the duration is - until it is closed?

[metalmatze]

Thanks!

Hi @metalmatze
Could you please, update docker image, probably it is outdated from current master.

I use 0.4.2 and have the same massage like here:
#79 (comment)

[metalmatze]

I need to cut another release for a docker image to be built and pushed. :)

[runningman84]

any news here?

While you're waiting for the release, you can easily add the template yourself with the TEMPLATE_PATHS environment variable. Create a directory with the template and mount it in your docker container, then set the value of the TEMPLATE_PATHS environment variable to that directory.

hi, tcassaert
How to create template, please send me the guide to create template.

[tcassaert]

@nguyencuong1990 you create a file for your template, let's say /opt/template.tmpl. The content of that file is an adapted version of https://github.com/metalmatze/alertmanager-bot/blob/master/default.tmpl, according to your needs.

Then when you start the telegram-bot, you can pass an environment variable TEMPLATE_PATHS=/opt/template.tmpl.

Thanks for reply

[tcassaert]

@nguyencuong1990, in your rules file, your annotation Summary is written with a capital S, while the template is looking for a summary with a regular s. That's probably why it's not included in the alert message.

Hi @tcassaert
When I add template.paths
--template.paths=/data/default.tmpl

Thank you so much!
