HAProxy (Prometheus)HAProxy (Prometheus)
Monitor HAProxy Load balancer using prometheus to feed Dynatrace with metrics.
Extension
- Product information
- Release notes
Overview
The HAProxy (Prometheus) uses Prometheus to collect data remotely. Every minute, data is collected from HAProxy devices and is continuously analyzed by the Dynatrace platforms. The new framework allows you to go beyond simple metrics and apply a topology-first approach to monitoring.
This is intended for users, who:
-
Would like to 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.
This enables you to:
-
Monitor infrastructure with a comprehensive dashboard
-
Use Prometheus as the data source
-
Take pre-emptive measures to avoid service degradations
Compatibility Requirements
HAProxy devices using Prometheus exporter
Details
Metrics collected:
- Throughtput / Connections
- Queues
- Request / Responses
- Sessions
- Cache / Compresor
- Status
- Process
The extension package contains:
- Prometheus data source configuration for metric ingestion
- Overview dashboard template
- Topology for servers
- Unified Analysis screen for server entity
This extension is built on top of the new Extension 2.0 Framework
More information can be found in the Product News Blog: https://www.dynatrace.com/news/blog/new-snmp-platform-extensions-provide-observability-at-scale-for-network-devices/
Get started
Simply activate the extension in your environment using in-product Hub, provide the required device configuration and you’re all set up.
