The Problem
How do you keep track of static Thresholds in a changing
environment?
A changing environment
Day 1
Server Bob
Specs:
4 CPU Cores
2 HDDs
1 Network interface
Server Alice
Specs:

Day 2
Server Bob
Specs:
2 CPU Cores

Solution
Let software like Ansible, Puppet, Chef do it for you.
Example
Example
object Host "awx.mw-krz-swd.de" {
import "CentOS7"
display_name = "AWX Server"
address = "10.194.29.136"
vars.hdds = [ "/dev/sda1" ]
vars.load_cload1 = 2
vars.load_cload15 = 1.5
vars.load_cload5 = 1.75
vars.load_wload1 = 1.75
vars.load_wload15 = 1
vars.load_wload5 = 1.5
}

// Picture of Changing infrastructure.
Where can they be used
Almost anywhere. Flexible Thresholds are designed for Storagenodes
and databases.
Why should I use them
Early alerting
