HPE H3C Switch extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Monitor your HPE H3C switches using SNMP.
Get started
Overview
The HPE H3C extension leverages SNMP to gather performance and health metrics from your H3C switches every minute. This data is seamlessly integrated into Infrastructure & Operations, offering quick, actionable insights at a glance.
Use cases
- Quickly identify problematic interfaces that are dropping or corrupting packets.
- Pinpoint hardware faults, misconfigurations or congestion issues affecting performance or reliability.
- Track real-time and historical bandwidth usage to understand traffic patterns.
- Monitor memory consumption on H3C switches to detect potential leaks or resource exhaustion.
Compatibility information
- SNMP v2c or SNMP v3
- Dynatrace version: 1.310 or higher
- ActiveGate version: 1.310 or higher
Activation and setup
Activate the extension in your environment Web UI using the Dynatrace Hub. Provide the necessary device configuration, and Dynatrace will automatically deploy the extension and begin monitoring.
For more details, see Manage SNMP extensions.
Details
The extension package contains:
- SNMP data source configuration for metric ingestion
- Topology definitions for HPE H3C switches
- Dashboards offering monitoring overviews
- Infrastructure & Operations entries for each created entity
The extension is built on top of the SNMP data source that is part of the Dynatrace Extensions framework. For more details, see Extensions.
Licensing and cost
Calculations are based on the assumption that you monitor all metrics for every feature set every minute:
DDUs: (4 + (8 * n_interfaces)) * 525.6 DDUs/year, per switch
DPS (Metric data points): (4 + (8 * n_interfaces)) * 525,600 metric data points/year, per switch
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.
