@sudesh (Sudesh) posted a new topic, subject "False New Relic Infra Alert". It read:

   Recently, our server infra agent triggered “Host not reporting” alert, however, when we reviewed our server and application, we didn't see any signs of an outage on our server.
    
    Below is the message triggered from New relic.
    
    Infrastructure host reporting status  
    (https://infrastructure.newrelic.com/accounts/712228/alertLanding?violationId=987836763)
    
    Host Not Reporting at least once in 5 minutes on ‘MyEvalsApp'
    
    Could you please review and let me know why the alert was triggered when the host was actually online.
    
    Thanks!

    we saw the same issue back on friday 7/17 around 6pm ET

    Hi @sudesh
    
    Keep in mind that Host Not Reporting alert conditions are specifically about the Infrastructure agent reporting to New Relic. Once the Infrastructure agent stops reporting for any reason, New Relic has no way of knowing whether that is due to a brief internet outage, the agent unexpectedly stopping, a transient network issue, or the host actually crashing. If a Host Not Reporting alert condition is set up when this happens, a violation will open _even if the host is still active_.
    
    If you take a look again at the page you linked, you'll see that the Infrastructure agent lost connection a few minutes before that violation and regained connection just before the violation closed:

    @manoj.kumar.k, this is likely what happened in your case, too. If you have a link, that will help to verify whether this is the case, but take a look to see if the Infrastructure agent lost connection just before your Host Not Reporting violation opened.
    
    I hope this helps!

After which, @Fidelicatessen (Sean Henry) added

    Hi @manoj.kumar.k
    
    Thanks for posting that link! If you follow the link on that page that says `Go to msjompa2 overview`, it will take you to this page which shows that the host lost connection – that's what caused the Host Not Reporting violation.
