I'm running Heartbeat using the official Heartbeat docker image. Ever since updating from 7.4.2 to 7.5.0, none of my HTTP monitors appear to be getting run. I have around 300 monitors configured with their schedule set to "0 0 \*/2 \* \* \* \*" (every 2 hours). I've tried changing it to "0 \*/5 \* \* \* \* \*" (every 5 minutes) and get the same result where no monitors are getting run. I then tried running only 3 monitors with schedule "0 \*/5 \* \* \* \* \*". Voila! Monitors are getting run.
So, there appears to be some kind of bug in 7.5.0 that when a large number of monitors are configured, then they just don't get run.
PS: No errors are appearing in the heartbeat logs when I've got the ~300 monitors configured.

[SOLVED]: False alarm. The problem was with the machine I was running heartbeat on. It wasn't powerful enough to handle ~300 monitors. After upgrading to better hardware, heartbeat 7.5.0 works as intended.

FYI, the scheduler fix in [https://github.com/elastic/beats/pull/14959](https://github.com/elastic/beats/pull/14959) should make heartbeat able to scale better. I'm hoping we can release this as early as 7.5.1

Looks like it'll be 7.6.0
