At least in the context of Checkmk, what’s the difference between a rule and a parameter? They seem to refer to the same thing. If a distinction does exit, I’m basically looking for succinct definitions of each. Examples would be great, too.
take a look at the manual. There you will find a lot of information: https://checkmk.com/cms_wato_rules.html#The%20predefined%20parameters
Generally a Parameter is a part of a rule. For every rule you can define individually Parameters. For. With the Parameters you can configure a rule.
There is another useful information: https://checkmk.com/cms_wato_services.html#parameters
The best way to understand the Parameters is to create a rule.
You can take a look at this tutorial too.
That helps. Thanks Anastasios.
