Installation
SimpleMonitor is available via PyPi:
pip install simplemonitor
Tip
You may want to install it in a virtualenv, or you can use pipx which automatically manages virtualenvs for command-line tools.
Create the configuration files: monitor.ini
and monitors.ini
. See
Configuration.
Warning
I know the configuration file names are dumb, sorry.
Running
Just run:
simplemonitor
SimpleMonitor does not fork. For best results, run it with a service management tool such as daemontools, supervisor, or systemd. You can find some sample configurations for this purpose on GitHub.
SimpleMonitor will look for its configuration files in the current working
directory. You can specify a different configuration file using -f
.
You can verify the configuration files syntax with -t
.
By default, SimpleMonitor’s output is limited to errors and other issues, and
it emits a .
character every two loops. Use -H
to disable the latter,
and -v
, -d
and -q
(or -l
) to control the former.
If you are using something like systemd or multilog which add their own
timestamps to the start of the line, you may want --no-timestamps
to
avoid having unnecessary timestamps added.
