Python script to monitor Linux Disk I/O matrix and save information in ClickHouse



Here is a sample Python script that monitors the disk I/O usage of Linux and saves the information in a ClickHouse database:

This script uses the psutil library to get information about the disk I/O usage and mysql.connector to connect and insert the information in a ClickHouse database. The script runs in an infinite loop, so it continuously monitors the disk I/O usage and saves the information in the database. You can add a sleep function to the loop to make it run periodically.

You will need to replace the <username>, <password>, <hostname>, <port>, <database> with the appropriate values for your ClickHouse setup.
Make sure that you have created the table disk_io_usage in the ClickHouse database before running the script, the table should have 4 columns read_count, write_count, read_bytes, and write_bytes
Also, you can use Grafana to visualize the data in the ClickHouse database to have a better analysis of the disk I/O usage.
