Pattern Anomaly Monitor

Monitor Pattern Anomalies in the Edge Delta web application.

Overview

The Pattern Anomaly Monitor alerts you about a threshold of anomaly spikes in a specific timeframe and for the configured source scope. You can use the alert to begin an investigation, such as by checking OnCall AI Analysis in the Logs - Anomalies page.

Create a Pattern Anomaly Monitor

To create a Pattern Anomaly monitor:

  1. Click Monitors and select Manage Monitors.
  1. Click + New Monitor and select Pattern Anomaly.

Configure Pattern Anomaly Monitor

The Pattern Anomaly Monitor evaluates the Pattern Anomaly count across all agents in the Fleet. In this example the anomaly count is grouped by namespace.

Monitor Scope

  • Source: Use autocomplete to select the sources you want to monitor. For example you can specify a number of agent tags. If you leave this blank all sources will be monitored.
  • Group by: You can group the monitored item by dimensions such as the agent tag, host, namespace etc. This option is required if you want to split notifications by group such as namespace.

Alert Conditions

Configure the thresholds that the monitored item should be evaluated against in this section.

  • You can choose to trigger when the evaluated value is Above, Above or equal to, Below or Below or equal to the thresholds.
  • You can select a warning and an alert thresholds. As you add the thresholds they are displayed in the graph relative to the current source’s values.
  • The Anomaly Multiplier is used to generate the pattern value, which is the number of spikes. The baseline value is determined for the preceding 4 hours. A lower multiplier will recognize and count more spikes, resulting in more alerts. As you change the Anomaly Multiplier you can view the number of spikes entering the warning and alert zones in the graph, and adjust accordingly.

Notification

See Monitor Notifications

To use source fields in the notification you must specify them in the Group By field in the Monitor Scope section and in the Group notifications by field in the Notifications section.
