- Add labels on this root message, like “order:12”, “url
- Add reply for each label you want to rewrite

Compute color and bg-color

Example for compute label “color”:

#label:color:08f1f4:0:10,ce352c : if value is >= 0 and value <= 10, color will be #08f1f4, else color will be #ce352c
#label:color:08f1f4:0:10,ce352c:11:20,fa6800 : if value is >= 0 and value <= 10, color will be #08f1f4, else if value is >=11 and value <= 20, color will be #ce352c, else color will be #fa6800

This reply : #TatDashing #label:0:value #value:0:/Internal/Alerts?tag=CD&notLabel=done&onlyMsgRoot=true will :

compute label “value” by
count messages from /Internal/Alerts with tag=CD and notLabel=done and onlyMsgRoot=true to avoid counting exclude alert replay.
