Heartbeat monitor auto reloading does now work

According to heartbeat documentation, heartbeat supports automatically reloading the monitor files periodically. In my installation of heartbeat, I have enabled this:

heartbeat:
  config:
    monitors:
      path: /etc/heartbeat/monitors.d//*.yml
    reload:
      enabled: true
      period: 5s

However, this does not work and I have to restart the heartbeat service every time I create new monitors or change existing ones.

This is how the heartbeat process looks like:

root      9883 14.1  1.1 1146752 97348 ?       Ssl  09:55   7:40 /usr/share/heartbeat/bin/heartbeat -environment systemd -e -d elasticsearch -c /etc/heartbeat/heartbeat.yml -path.home /usr/share/heartbeat -path.config /etc/heartbeat -path.data /var/lib/heartbeat -path.logs /var/log/heartbeat

The heartbeat monitors have the following permissions:

-rw-r--r-- 1 root root 324 Sep 10 11:05 monitors.d/twmn.elasticsearch.yml

and the folder containing the monitors:

drwxr-xr-x 2 root root 102400 Sep 11 09:55 monitors.d/

Am I doing sth wrong?

Hi, what version of Heartbeat are you using?

Also, could you run Heartbeat with logging.level: debug set in your heartbeat.yml, then change a monitor or create a new one, and post the Heartbeat logs for the following 10 seconds or so?

Thanks,

Shaunak

I am using version 7.8.1. I remember it being this way with a few previous versions as well. Here is what journalctl says. I run journalctl -f first, then edit a monitor from enabled: False to disabled: True, wait for half a minute and then restart the service manually to have it loaded. I remove many lines that simply count the events reported.

Looking at the last three lines of the logs it looks like, for some reason, Heartbeat doesn't like the monitor configurations. Would you mind posting those here (with any sensitive information redacted)?

Thanks,

Shaunak

Did notice you have an extra / in your path probably not the issue but it is extraneous
