How to install the Autonomous Anomaly Detector.
This page describes StackState version 4.3.
The StackState 4.3 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.3 version range to upgrade to a more recent release.
Overview
Anomaly detection identifies abnormal behavior in your fast-changing IT environment. This helps direct the attention of IT operators to the root cause of problems or can provide an early warning.
Installing the Autonomous Anomaly Detector StackPack will enable the Autonomous Anomaly Detector (AAD). The AAD analyzes metric streams in search of any anomalous behavior based on its past. Upon detecting an anomaly, the AAD will mark the stream under inspection with an annotation that is easily visible in the StackState user interface. An
Metric Stream Anomaly Event for the incident will also be generated which can be inspected at on the Events Perspective.The AAD requires zero configuration. It is fully autonomous in selecting the metric streams it will apply anomaly detection to and the appropriate machine learning algorithms to use for each.
Installation
Prerequisites
The AAD StackPack can only be installed within a Kubernetes setup. Please make sure that this is supported by your StackState installation.
If you are not sure that you have a Kubernetes setup or would you like to know more, contact StackState support.
Install the Autonomous Anomaly Detector (AAD) StackPack
To install the AAD StackPack, simply press the install button. No other actions need to be taken. The AAD will need to train on your data. The first results of the AAD can be expected within an hour.
Frequently Asked Questions
How does the AAD decide what to work on?
The AAD scales to large environments by autonomously prioritizing metric streams based on its knowledge of the 4T data model and user feedback. The metric stream selection algorithm ranks metric streams based on the criteria below:
- Components in views that have the most stars by the most users are ranked highest.
- From those components, the metric streams with the highest priorities are ranked highest. See how to set the priority for a stream.
- Metric streams with a configured baseline will not be selected at all. See anomaly detection with baselines.
You cannot directly control the stream selected, but you can steer the metric stream selection of the AAD by manipulating the above mentioned factors.
Can I get alerted based on anomalies?
Yes. The AAD itself does not alert on anomalies found, but anomaly health checks can be placed on components to automatically change the health status of the component to
DEVIATING. This health state change event can then trigger notifications via event handlers.How fast are anomalies detected?
The AAD ensures that prioritized metric streams are checked for anomalies in a timely fashion. Anomalies occurring in the highest prioritized metric streams are detected within about 5 minutes.
How do I know what the AAD is working on?
The status UI of the AAD provides various metrics and indicators, including details of what it is currently doing (see troubleshooting).
Uninstall
To uninstall the AAD StackPack, simply press the uninstall button. No other actions need to be taken.
