Description

Coolify currently supports notifications through various channels, including Email, Slack, Telegram, and Discord. This is a great feature for monitoring deployments, cleanups, errors, and other events.

However, when using Telegram (my primary channel), notifications do not include any identifier for the specific server or project they originate from. My Telegram bot is connected to over 20 different projects/servers, and as a result, it's often unclear which server a notification refers to—especially in cases of errors, revivals, or failures. For example:

• Deployment failure messages like "Coolify: Deployment failed of mbozhik/example" do not consistently specify the server.
• Routine messages like "Forced Docker Cleanup Job executed successfully. Disk usage before: 17%, Disk usage after: 17%." or "Coolify: Your server 'localhost' is unreachable." appear without server context when multiple servers are involved.
• Error notifications, such as "CheckHelperImageJob failed with: cURL error 6: Could not resolve host: cdn.coollabs.io", also lack this detail.

This makes troubleshooting and monitoring more difficult, as I have to cross-reference the dashboard or logs manually. I haven't tested other channels like Email or Discord extensively, but the issue is particularly noticeable in Telegram, where a simple server token, name, or ID in the message body would help identify the source immediately.

If this is confirmed as a general problem affecting other users (and not just a configuration on my side), I am willing to contribute by creating a Pull Request (PR) to implement this feature.

Attached are screenshots of example Telegram notifications to illustrate the lack of server identifiers:

• Screenshot 1: Server revival notifications.
• Screenshot 2: Additional cleanup and successful deployment messages.
• Screenshot 3: Error and test notifications.

This improvement would enhance usability for users managing multiple servers via a single notification bot/channel.
