Actions

Test a zabbix action or escalation

To test actions create a fake test trigger for your scenario (Host, Hostgroup, Severity).
We'll use the "vm.memory.size" from the Linux OS template to crate a fake trigger.

  • Configuration -> Hosts -> myhost.example.com -> Triggers
  • Add Trigger
    • Name: No more beer in the fridge {HOST.NAME} (Test Trigger)
    • Expression: {myhost.example.com:vm.memory.size[available].last()}>1
      • Note: This is usually always true, as the available memory is bigger than 1 byte
    • Severity: Desaster (or as you need to test your action)
    • Enabled: yes
    • "Update"

To disable, but retain the test trigger, change the expression to "<1", or disable the trigger completely.

 

Understanding and using Zabbix action operations

https://www.zabbix.com/documentation/3.0/manual/config/notifications/action/escalations?s[]=escalation

I found the operations tab quite confusing, especially "Default operation step duration" and the "Step" numbers.
Here is how it works:

  • Default operation step duration: e.g. 300sec (5)min
    • This is the "time" grid you choose. If you define "300" you'll operate in a 5 minutes grid.
  • "Step" Numbers
    • These are the numberd steps in your time grid. Example:
      Step1 starts immediately. Step2 starts after 5 minutes, Step3 after 10minutes.
    • The second value defines how often the step declaration will be repeated. "0" means infinitly.
      Example: 2-0 means the operation is first performed after 5 minutes, and then repeates every 5 minutes forever.
      Example: 2-2 means the operation is performed exactly 5 minutes after the incident.
      Example: 2-4 means the operation ist performed 5,10 and 15 minutes after the incident

 

Users

Create a new user with access to some data:

  • Create host group with desired hosts
  • Create group with read-only permission for host group
  • Create user with group
  •
