To set up all scripts in the current directory run this:

Just use it like this in a cronjob:

The first parameter is the healthcheck uuid instead of the script file you can als pass the command to execute directly after the uuid. The pipe to put all output to a log file is also optional.

Place a .gotify file in the same direction as the script and put the application token in. Append the following line to /etc/pam.d/sshd:

session optional seteuid /path/to/


Add the following in crontab:

*/5 * * * * /root/exporter/ "<your_dir_pattern>" "<your_key>" | sponge /path/to/textfiles/directory-size.prom
* * * * * /root/exporter/ | sponge /path/to/textfiles/active-sessions.prom

Add the textfiles dir as param to node_exporter:

node_exporter /path/to/textfiles ...
