## Vue d’ensemble

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers, but due to its simplicity and small size can be used on embedded devices as well.


**Version incluse :** 3.15.0~ynh2

## Avertissements / informations importantes

### Upgrade

By default, a backup is performed before upgrading. To avoid this, you have the following options:
- Pass the `NO_BACKUP_UPGRADE` env variable with `1` at each upgrade. For example `NO_BACKUP_UPGRADE=1 yunohost app upgrade monitorix`.
- Set `disable_backup_before_upgrade` to `1`. You can set it with this command:

`yunohost app setting monitorix disable_backup_before_upgrade -v 1`

After that, the settings will be applied for **all** the next updates.

From command line:

`yunohost app upgrade monitorix`

### Backup

This application now uses the core-only feature of the backup. To keep the integrity of the data and to have a better guarantee of the restoration it is recommended to proceed as follows:

- Stop Monitorix service with this command:

`systemctl stop monitorix.service`

- Launch Monitorix backup with this command:

`yunohost backup create --app monitorix`

- Backup your data with your specific strategy (could be with rsync, borg backup or just cp). The data is generally stored in `/var/lib/monitorix`.
- Restart Monitorix service with theses command:

`systemctl start monitorix.service`

### 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

        disk            = y
        lmsens          = y

```

In this config we have :
- 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.
