Monit can monitor qBittorrent and notify you if it stops running for some reason. Setting up a completely automated home server is awesome. But what if one of your apps fails and you did not even know? You may be waiting for your movie or episode to be downloaded but it never happens because the app has stopped functioning. Monit is an automatic monitoring, maintenance, and repair utility for Unix systems. If your qBittorrent WebUI fails, Monit can send you an email alert. It can even try to restart qBittorrent-nox (daemon). In this Monit tutorial, I will describe how to monitor qBittorrent with Monit system monitoring app. I am assuming that you have already installed and configured Monit following my previous guide.
On my recently built energy-efficient home server, I test and run several apps including qBittorrent. I use Monit to monitor several services listed below:
Monitor your home server with Monit:
- Home server system load monitoring (CPU, RAM, Swap)
- Server hard drive storage monitoring (HDD space)
- Motherboard temperature monitoring
- Processor or CPU temperature monitoring
- Monitor Hard drive SMART health and temperature
- Monitor file server status (Samba and NFS)
- Monitor web server status (Apache, NGINX, and MySQL)
- Monitor CouchPotato process status
- Monitor SickBeard process status
- Monitor SickRage process status
- Monitor SABnzbd process status
- Monitor Webmin process status
- Monitor qBittorrent process status
- Monitor Transmission process status
- Monitor ShellInABox process status
In this guide, I will show you how to monitor qBittorrent process status so that the automatic download system you setup keeps running as it should. Just another layer of automation for your home server.
Before enabling qBittorrent monitoring, it is required that you have a working Monit instance with a proper
/etc/monit/monitrc file. Monit configurations for various services are loaded from
1. Find qBittorrent Port
First, you will need to find what port your qBittorrent daemon setup is listening on. If you find this guide interesting, you probably already know your port. In case, you do not know your port number there are couple of ways to find it. If you installed qBittorrent using AtoMiC ToolKit then you can use the “Access Details” feature from within AtoMiC ToolKit qBittorrent submenu.
Alternatively, you can open qBittorrent settings file and look for the port. If you followed our qBittorrent WebUI installation guide then you can open settings file using the following command:
Then, look for the port number. Find the line similar to:
In this guide, we are going to assume you are using port 8086, which is the qBittorrent daemon default port.
Setup Monit qBittorrent Monitoring Script
To monitor qBittorrent with Monit, create a Monit configuration file using the following command:
Copy the following contents to it, save, and exit (press Ctrl X, press Y, and press ENTER).
check process qBittorrent matching "qbittorrent-nox" start program = "/etc/init.d/qbittorrent-nox-daemon start" stop program = "/etc/init.d/qbittorrent-nox-daemon stop" if failed host 127.0.0.1 port 8086 type TCP for 2 cycles then restart if 2 restarts within 3 cycles then unmonitor
If you are using qBittorrent behind SSL (HTTPS access) then use
TCPSSL instead of
TCP in the above code block. This code will make Monit send you an email alert when qBittorrent is not running. As example, the picture below shows 2 emails from monit: one when CouchPotato process was found to be not running and another after Monit successfully restarted CouchPotato.
A cycle is 1 monitoring period as set in
/etc/monit/monitrc. If 2 restarts occur within 3 monitoring cycles, Monit will stop monitoring qBittorrent process status instead of bombarding you with email alerts. You can customize the above rules as you please. [Read: What is Usenet and why is it better than Torrents?]
Test and Reload Monit
Once you make any changes you have to test Monit configuration:
sudo monit -t
You should see the following message: Control File Syntax OK. Then, check to see if Monit is already running using the following command:
sudo /etc/init.d/monit status
If Monit is running, reload Monit configurations using the following command:
sudo /etc/init.d/monit reload
If Monit is not running, then start it using
sudo monit command instead. The whole sequence of commands for testing and reloading Monit is shown in the picture below.
Now, fire up your web browser and visit one of the following URLs depending on how your Monit is configured (be sure to use the correct port number):
- http://IPADDRESS:2812 (local network IP)
- http://domain.com:2812 (if you have domain name pointing to your server)
Right now, I do not have qBittorrent running. If it was running, you should see qBittorrent process status in the Monit status shown in the picture below.
That is it for qBittorrent monitoring with Monit. As you can see Monit allows for automatic server monitoring, which can be a big help for system administrators. Monit Wiki page has several examples. More home server specific Monit examples to follow, so keep checking back.
