Telegraf agent ping checks on RHEL 9 fail to report metrics and show a red status in Aria Operations

Products

• VMware Aria Operations (formerly vRealize Operations) 8.x

Issue/Introduction

- Ping check availability metrics drop to 0% and the object status turns red in the Operations Manager console

- The availability value could return to 100 when edit the object and save without any change

- Default Telegraf ping parameters lack explicit "Timeout" and "Deadline" values

 

Environment

VMware Aria Operations 8.18.x

Resolution

Update the Ping Check settings in the Manage Telegraf Agents UI with explicit values for each agent:

- Count: 3 (Sends 3 ICMP packets per check)

- Ping Interval: 1.0 (1 second between packets)

- Timeout: 3.0 (Time in seconds to wait for a reply)

- Deadline: 10 (Hard ceiling in seconds for the entire ping execution to terminate)
