De un momento a otro he perdido la visual del monitoreo sintetico, Dynatrace ya no recibe datos de los mismos, aunque los servicios estan activos, despues de un rato, varios dias, se recupero el monitoreo de la mitad, pero la otra mitad sigue sin reportar

[_Edit from Moderator with Google translation:_

From one moment to the next I lost sight of the synthetic monitoring, Dynatrace no longer receives data from them, although the services are active, after a while, several days, monitoring was recovered for half, but the other half still does not report]

Hi,

This is so generic, without more information, I would say open a support case.

Best regards

Yes, I agree with Anton, the easiest way to investigate this would be over chat or with a support ticket. Please provide the link to the monitor in the chat/ ticket.

That said, for no data:

- Check for maintenance windows on the monitors and on the services they’re connected to.
- If it’s running on private locations,
  - Check that the locations are up and running.
  - Check for error messages in the&nbsp;[relevant logs](http://Useful%20Synthetic%20ActiveGate%20logs).

- If it’s on managed, check the Cluster ActiveGate that is used for routing traffic and any devices in between, like firewalls, etc, to confirm nothing is preventing the data from being returned to the cluster.
