Breakdown
Steps
In this example we can see two steps:
- db-prod1-no-space - checks db space of db prod1
- db-prod2-no-space - checkd db space of db prod2
Conditions
The action has two threshold conditions:
condition:
- type: threshold
value: "{{ steps.this.results }}"
compare_to: 90% # Trigger if more than 90% full
But now we’ve added an alias to each condition, so it’ll be easier to check it in the action itself.
Action (if statement)
The action now uses the if statement to alert if one of the databases has less than 10% disk space left.
We can use if: "{{ A }} and {{ B }}" to alert only if both databases has less than 10% disk space left.
Note that its the default behavior so you may achieve the same without specifying if statement.
