Plotting graphs for MYSQL

Question

I was executing following command

mysqladmin ext -i1 -c3600

It produces valuable output but I want to use the output to plot graphs so that I can visualize inserts, updates, buffer and other stuff.

Anyone has any idea on how to use the output to plot graphs ?

Answer 1

There are values that you need to graph with absolute values, such as

• Innodb_buffer_pool_bytes_dirty
• Threads_connected
• Threads_running

There are also values whose delta needs to be calculated and graphed, such as

• Queries
  • Com_select
  • Com_delete
  • Com_update
  • etc ...
• Incoming and Outgoing Traffic
  • Bytes_received
  • Bytes_sent

You should consider using Nagios XI or MONyog to do all that for you.

If you want to be a hero, use Google Charts

• Google Chart API - A Real World Example
• Sample Chart You Need to Craft in a Bash Script Using the Deltas and Absolute Values

I used Google Chart a few times and got away from it. It does work, but you have a lot of coding to store the absolute values and calculate deltas for specific variables. Then, you script the URL from the values and render the URL in a browser.
