How can I create a filter to show me the agents that need to be updated - those that are not up to date on the latest version?
There are a couple of tricks to this, firstly, the agent version, such as 188.8.131.52 is a string, and so trying to use less-than or greater-than operators on strings often provides unexpected results.
For this reason, the agent version is actually stored as a number, which each of the dots being represented as a 0, thus
184.108.40.206 becomes 8000003 and 220.127.116.11 becomes 60300019.
This allows us to do less than operations.
Please see the attached screenshot showing how to filter on agents with a lower version than 18.104.22.168
