Monitoring error(Missing metric)

• 
  Hello friends.

  We're having trouble with Sql Monitor. Missing metrics on different servers and I can't see requests.
  For example: Today at 10:00 AM I restarted the Base Monitor service, later at 15:11 PM on one server the metrics disappeared. However, I did not receive any alerts.

  At this time, the SqlMonitor and Database server was available, I did not see any errors there.

  
  

  How can I fix this?

  Hello everyone.

  We're having trouble with Sql Monitor. Missing metrics on different servers and I can't see requests.
  For example: Yesterday at 10:00 AM I restarted the Base Monitor service, later at 15:11 PM on one server the metrics disappeared. However, I did not receive any alerts.

  At this time, the SqlMonitor, Database server was available and metrics collected on other servers.

  I didn't find any errors in the logs.

  After the service is restarted, the metrics are collected. Restarting the service every day is not an option.
  
  

  How can I fix this?

  Hi Abylay,
  
  As mentioned on the ticket you raised, looks to have been a sampling error from the Base Monitor and a restart of this service brought it back.
