Monitor HAProxy Load balancer using Prometheus to feed Dynatrace with metrics.
1 of 10
Get started
Overview
Monitor the HAProxy load balancer using Prometheus to collect data remotely and analyze it in Dynatrace using a topology-first approach to monitoring with the 
HAProxy (Prometheus) extension.
Use cases
- Monitor the performance of an edge proxy or ingress proxy.
- Focus on Kubernetes calls for supporting the most popular services of this kind in Kubernetes.
- Monitor infrastructure with a comprehensive dashboard.
- Use Prometheus as the data source.
- Take pre-emptive measures to avoid service degradations.
Requirements
HAProxy devices using the Prometheus exporter.
Activation and setup
Find the extension in Dynatrace Hub to start the installation.
For more information on the related Prometheus extension, see Dynatrace Prometheus Extension Documentation.

Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
