Hi Dariusz,
Thanks for the information.
So as you mentioned the Alert is a basic service monitor
Also the service is set to startup type automatic
I would suggest you to check and perform the below.
Check if there is any override set to the monitor using the override summary.
Also is the monitor working fine on other Agents (Are the alerts appearing when the service is stopped on other agents)
Can you check the health state what you have set ? It should be like the below.
Also if the above mentioned is correct, Monitor is configured correctly and No overrides are set and the alert appears on other agents when the service stops there then try the below.
Login to the Agent.
Stop the healthservice
Go to C:\Program Files\Microsoft Monitoring Agent\Agent
Here rename Health service state folder to Health service state_old
Start the Healthservice
Post doing the above a new Health service state folder will be created forcing a new alerting configuration.
Wait for some time and check the Health explorer and also by stopping the service to see if the alert appears then or not.
Post me the re
