Filter notification report

[Bloopps]

I recently discovered the WATCHTOWER_NOTIFICATION_REPORT option.
I really like the little summary provided after each scan, but since Watchtower runs every hour, I get a lot of notifications just to report the scans.

It would be nice to be able to filter them and only receive a message when there is something other than a scan without any major action. I don't think I saw an option for this when I looked through the documentation. Let me know if I missed something.

I am in the same boat and tried to set WATCHTOWER_NOTIFICATIONS_LEVEL. On info, there are way too much infos, on error there are none (maybe on a fail, but not on successful updates AFAIK. So I tried warn, since I thought this would tell me when something happened (also when containers where updated) but not when "nothing happened". I could not really tell the difference what warn exactly does, but not that. :D Any ideas on how to "only get reports if something happened"?

Updates on my own post:
WATCHTOWER_NOTIFICATIONS_LEVEL onyl controls whats ending up in the log and has nothing to do with reports. If you want to reduce notifications, you have to change the notification template. This is "solving" my problem (I only want notifications if something was updated or something went wrong). Maybe this helps somebody else.

      WATCHTOWER_NOTIFICATION_TEMPLATE: |
        {{- if .Report -}}
          {{- with .Report -}}
            {{- if (or .Updated .Restarted .Failed) -}}
              {{len .Scanned}} Scanned, {{len .Updated}} Updated, {{len .Restarted}} Restarted, {{len .Failed}} Failed
              {{- range .Updated}}
        - {{.Name}} ({{.ImageName}}): {{.CurrentImageID.ShortID}} updated to {{.LatestImageID.ShortID}}
              {{- end -}}
              {{- range .Restarted}}
        - {{.Name}} ({{.ImageName}}): {{.State}}
              {{- end -}}
              {{- range .Failed}}
        - {{.Name}} ({{.ImageName}}): {{.State}}: {{.Error}}
              {{- end -}}
            {{- end -}}
          {{- end -}}
        {{- end -}}
