Hi!
I've noticed that sometimes I don't receive a notification for a triggered alert, meaning the action isn't triggered.
I checked the cluster logs and saw this:
I've noticed that these errors often appear on both of my monitors. That is, these monitors sometimes send alerts correctly, and sometimes they don't, and I can't figure out what's causing this.

I'd like you guys to look at my monitors and suggest how I can improve them or "lighten" them. Because one of the monitors has over 3,000 hits. I don't know if this is correct or not.
I pinned 2 txt files (my both JSON monitors) please look at this.
