What is Anomaly Detection for roles?

The Anomaly Detection for roles function uses machine learning to detect and notify users via alerts when load tendencies deviate from the norm. The function uses about 2 weeks worth of metrics as learning data and recognizes the difference between daytime and nighttime load trends and weekday and holiday load trends. For example, the following conditions would be determined as anomalies.

  • When there’s a sudden load increase at night when the load is usually low.
  • When only one host in a role has a low load during the daytime when the load should be high

As described above, Anomaly Detection for roles can catch abnormalities that are not easily detected with general fixed threshold settings.
