Switching Printing using CUPS

Applications Infrastructure Monitoring
1

Hello,

I have installed CUPS on 2 RHEL 9 instances and accessing them using Load Balancer under Azure Cloud,
my /var/spool/cups file system is shared between 2 servers.
I want to configure, my pending print queue's to be printed from 2nd printer if first server goes down.
says, my primary server has 100 spool queues, and it went down after printing 50 queues, how I can restart printing on my secondary print server for remaining Queues?

Normally, sys admins write scripts for these kind of tasks with functions like:

  • Monitor the network / servers for up / down / delay / etc
  • Log the results of monitoring (optional, but generally a good idea)
  • Take action based on results of monitoring
  • Log the results of taking actions (optional, but also generally a good idea)

How you decide the monitor your network / hosts is up to you.

How you wish to reconfigure CUPS based on your monitoring rules is up to you.

The programming language and approach is also up to you and your own skill level and experience.

Generally speaking, many write these types of scripts using bash. Some might use python. Others might use ruby or whatever their favorite programming / scripting language happens to be.
