[Official Tutorial] Monitoring Linux Server Statistics 2

Posted by Hans Scharler,

ThingSpeak can be used to easily monitor CPU usage %, memory usage %, and disk usage % on any Linux machine connected to the internet.

First, create a new Channel, and fill out the field names as follows: Field 1 = “CPU Usage (%)”, Field2 = “Memory Usage (%)”, Field 3 = “Disk Usage (%)”.

ThingSpeak Channel Settings

Next, add the open-source server statistics script to your server, which can be found at: https://raw.githubusercontent.com/iobridge/thingspeak/master/lib/server_stats.sh

Inside the script there’s an API Key variable, which should be replaced with your specific Channel’s API Key (leave the single quotes, and only replace the X’s): api_key='XXXXXXXXXXXXXXXX'

For the script to work properly, install the “bc” package via: sudo apt-get install bc

Then make the script executable: chmod +x server_stats.sh

Finally, edit your crontab file: crontab -e

Make the script execute every minute by adding this line to your crontab (make sure you use the proper path to the script): * * * * * /path/to/server_stats.sh

The script will then automatically POST server stats to the Channel specified by the API Key every minute.

You can see some of the ThingSpeak server statistics here:

For the right guidance for the monitoring of the Linux can also be guided by the Apple Support Number for the actual need to the guidance and the solution of the others problem regarding the Apple device.
