Big true or false dot

Grafana
1

Hi! I need some help. I’m reading a logfile with Loki/Prometheus that looks like this:

21-10-2025 5:26  
a jour  

22-10-2025 5:28  
a jour

(a column for the date, a column “Line” for “a jour”)

My query is:

{filename="/var/logs/SyncTrimble/status_list.txt"}

I’d like to display a big green or red dot (or maybe a square or triangle — just something clearly visible) if there’s a line for today.

Any idea how to do that? Thanks for the help!
