Alerts are sent to telegram topics - but the image-renderer breaks it

[tonypowa]

What happened?

Hello!

Grafana 10.4.2 - thanks for the opportunity to send telegram alerts to individual topics.

In our team we use image-renderer. And when distributing alerts across topics, everything breaks down - pictures are sent as messages to the General or Main channel. Can anything be done about this?

After all, the meaning of the whole idea with topics in this case is lost

The ability to receive alerts on topics with images

Summary: The issue, opened by user tonypowa, reports a problem where alerts with images sent to individual Telegram topics in Grafana 10.4.2 are being incorrectly routed to the main channel due to an issue with the image-renderer, thereby defeating the purpose of having topic-specific alerts.

Hi @tonypowa, thank you for reporting the issue with image-renderer and telegram alerts in Grafana 10.4.2. To better understand the problem and work towards a solution, could you provide us with some additional information? Below is a list of questions and items that would be very helpful in addressing this issue:

• Could you provide the steps to reproduce the issue in a bit more detail? Specifically, what configuration steps or operations lead to the alerts being sent incorrectly?
• Have you configured any specific settings related to the image-renderer or Telegram notification channels that might affect the behavior?
• Is there any error message or log output that could illustrate what goes wrong when the images are sent to the main channel instead of the specified topic?
• Could you provide screenshots showing the configuration of your Telegram notification channels and the results when the alert is triggered?

Hi @tonypowa, it seems like you are experiencing an issue with Grafana's alerting functionality and image rendering when using Telegram as a notification channel. I believe this issue is relevant to the Alerting project. The team responsible for alerting features may have insights into how alert images can properly behave with topic-based notifications in Telegram. I recommend transferring this issue to their attention for further assistance.
