Display Monitor Groups in Mail Subject

📑 I have found these related issues/pull requests

Similar to #4384 I want to request a new Tag {{MONITOR_GROUP}} or just {{GROUP}} that would translate to the monitor group of a monitor or just an empty string if a monitor isn't part of a particular group.

🏷️ Feature Request Type

Change to existing notification-provider

🔖 Feature description

I would like to use a {{MONITOR_GROUP}} tag in my custom mail subject to better differentiate my self hosted apps.

✔️ Solution

{{MONITOR_GROUP}} or {{GROUP}} should translate to the group a monitor belongs to or an empty string if the monitor isn't part of any group.

❓ Alternatives

I have considered either including the monitor group name in the application name, making my naming a bit redundant.

I also could setup multiple SMTP Notification providers. One for each Monitor Group, than I could write the group name into the custom subject.

📝 Additional Context

I'm using monitor groups heavily to bundle up my hosted applications and their dependencies. For example i have a Nextcloud Setup with 3 containers (database, redis, app). In Uptime Kuma I created a Monitor Group called "Nextcloud" and it's children are called "App", "Database", "Redis" and "Reverse Proxy" (to check if the reverse proxy is working correctly). And I used this structure for other services as well (Forgejo, Rustdesk, etc.) So I have multiple Monitors called "Database" each belonging to a different group.

If I now receive a Mail for a service that goes down it just says "[Database] [🔴 Down] Request failed with status code 404" which makes it hard to know what database exactly went down because it could have been the one from the Nextcloud or Forgejo Groups.

In v2.0 the entire monitorJSON is included in the request
=> you can customise your template as needed (not just the weird Regex-replacements in v1.0):

• Feature: SMTP-templating of customBody and customHeader via liquidjs #3414

=> this issue is already resolved in master, see #4500 for the status of said release.

For other monitors, this is tracked in:

• notifications which group a child is in #4258
• Implement Templates for Notifications #646

Oh I didn't know, thanks for clarifying that.
