Remove

Due of the backup core only feature the data directory in /var/lib/monitorix is not removed. It must be manually deleted to purge user data from the app.

More sensor

If you want to see the temperature of some sensor you can install the lm-sensor packet. For disk temperature you can instal the hddtemp packet.

Custom config

If you want do custom the monitorix config for more personnal information you can add a file in /etc/monitorix/conf.d/. This config file will be overwritte the original config in /etc/monitorix/monitorix.conf.

You will have a full complete documentation for monitorix config here : https://www.monitorix.org/documentation.html

By example you can extends the basic config by this :

priority = 5

In this config :

• We set the process priority to 5 (which mean that it will be lower priority than the other process).
• We get the lmsensor sensor data.
• We get some sensors data not accessible with lmsensor (with gensens)
• We check the disk health and send an email if any error happens. For that you need to make some script. An example is available in /usr/share/doc/monitorix/monitorix-alert.sh.
• We check the filesystem.
• We check the traffic in the network card.
• We check some process.
• We send every day, week, month and year a rapport.
