Get started
Overview
Track the health state and performance of your Juniper network infrastructure.
This extension uses SNMP to provide unified analysis capabilities for Ops, DevOps and IT admins.
Use cases
- Monitor health state and performance of their Juniper devices.
- Analysis support for Ops, DevOps, and IT admins.
- Monitor infrastructure with a comprehensive dashboard.
- Detect traffic anomalies and generate alerts based on these.
- Take pre-emptive measures to avoid service degradations.
Compatibility information
- SNMPv2c or SNMPv3
Activation and setup
To enable the extension, find Juniper Networks (SNMP) in the Dynatrace Hub.
Details
The extension package contains:
- The SNMP DataSource configuration.
- A dashboard template.
- A Unified Analysis screen template.
- Topology definition and entity extraction rules.

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.
