Template for Monitorying SSH

What to do not using template?​

We can add items to check for host.

Assuming the target host is already added to monitoring:

  • Find the target host in the Host list

  • Open Items of the host

  • Choose Create item:

    • Name: SSH Check
    • Type: Simple check
    • Key: net.tcp.service[ssh]
    • Type of information: Numeric (unsigned)
    • Update interval: e.g., 60 seconds
    • Add

And we have to add that to each host we want to use, so... let's use Template.

Create template​

Add template​

  • Go to Templates
  • Click Create template

    • Name: SSH is DOWN on {HOST.NAME}
    • Severity: e.g. “High”
    • Expression: sum(/SSH Monitoring/net.tcp.service[ssh],#3)=0 👈 This means: “Alert if, sum of the last 3 data is 0 (SSH was down for all three checks).”
    • Key: net.tcp.service[ssh]
    • Add
