MS Teams alert card does not show info on mobile interface

[jpds]

What did you do?

Configured Alertmanager to send alerts to a chat in Teams with the Workflows webhook. I'm also using the patch at: #3921

What did you expect to see?

An alert description sent to the monitoring chat, this is fine on desktops, but on mobiles - currently on the alert title is displayed.

What did you see instead? Under which circumstances?

Just the alert title, there's no other alert information included which makes it hard for mobile users to action alerts.

Environment

• System information: NixOS 24.05

• Alertmanager version: 0.27.0.

• Prometheus version: 2.53.1

Hello! 👋 Does this happen on official Alertmanager releases, or just custom builds using #3921? If the latter, please close this issue and let's bring the discussion to the PR instead.

[jpds]

It's on both.

[grobinson-grafana]

On the official Alertmanager release, how are you using Power Automate workflows? Are you using one of the workarounds suggested in #3920? Can you also test with Office365 connectors to see if it's still broken?

[jpds]

On the official release - I was using the old webhooks functionality - that is broken in the same way (as with the PR code + Power Automate).

But it works on desktop? Could you share a screenshot of the same message on both desktop and mobile?

[jpds]

Of course, here's what it looks like on a desktop with all the extra info in place:

And here it is on the mobile app:

There's also nothing else available on a mobile when it is pressed/held down.

I think this is a bug in Microsoft Teams app, not Alertmanager.

Could you please try to change the version of your card? Try version 1.4

@fabriciodf Thanks for the suggestion, I've adjusted the value at:

• https://github.com/prometheus/alertmanager/pull/3921/files#diff-0e06d07cf4972aad8c889cb25bdb906e6b7901d2839a932ad4fccc7e60005490R154

Will see what the next alert shows in the 📱 app.

Sadly no change. @zhan9san would you happen to have any ideas about this?

@jpds

Thank you for reaching out to me.

If I understand correctly, both Alertmanager and Power Automate are responsible for sending the request with the appropriate payload. If the message does not display the information as expected, I don't believe the issue lies with Alertmanager.

Hello. Do you fix this issue?

@khanhnt99

I am afraid I have answered the question in my previous reply. #3943 (comment)

Do you still have any concerns?
