Monitoring unavailable events

A monitoring unavailable event indicates a widespread monitoring interruption, where the majority of your installed OneAgents lose their connection with the Dynatrace server.

Monitoring unavailable events

Symptoms

This usually manifests itself as a lack of visibility in terms of both availability and performance monitoring. In case of a monitoring interruption:

  • Dynatrace automatically suppresses all individual Host unavailable problems and alerts you to the monitoring interruption.
  • All hosts are set to the availability state Unmonitored for the duration of the monitoring outage.

Probable causes

Monitoring interruptions can have different root causes depending on the type of Dynatrace deployment you're running:

  • Dynatrace SaaS environments are administered by the Dynatrace DevOps team, who post all operational issues to dynatrace.status.io.
  • For environments running in Dynatrace Managed deployments, it's most likely that the monitoring interruption is caused by an issue within your own data center or network configuration.
