SNMP Traps extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Supplement network monitoring with event-based data reported via SNMP traps.
Get started
Overview
Use SNMP traps to gain more details about the health state of your network devices.
Add event-based data to all metrics reported in combination with dedicated SNMP extensions. This lets you diagnose performance and availability issues even better.
Use cases
- Topology for SNMP trap devices, derived from the IP address of the agent that send the traps.
- A dashboard that offers a monitoring overview for the SNMP traps that are received by the extension.
- A Unified Analysis page for SNMP trap devices.
- Log ingestion for SNMP traps. SNMP Traps are received immediately and ingested as logs.
- Track number of traps reported by their types, so that you can enable alerting for issues such as port flapping.
- Review individual events reported by the SNMP devices, so that you have more details that explain metric anomalies.
- Get unified visibility for metrics and traps.
Compatibility information
- Supports SNMPv1, SNMPv2(c), and SNMPv3.
- Event forwarding is not supported.
Activation and setup
To enable the extension, find SNMP Traps in the Dynatrace Hub.
To enable log ingestion, select the Events feature set in the monitoring configuration.
Details
Licensing and cost
This extension collects a count of SNMP traps each minute. Events are ingested as
- Metric datapoints
- Logs
Metrics
Once data is produced, this is ingested as metric datapoints and subject to license consumption. The measurement unit for metric ingestion is based on metric datapoints.
To estimate the amount of metric datapoints produced by your extension configuration, use the following list. This gives you
- a number of metrics per feature set.
- a multiplier value depending on which entity the metric is split by.
Add all of these up and you will have the number of datapoints produced every minute.
Events1 * SNMP traps devices
Assuming there is one SNMP trap device being monitored (one metric * one SNMP trap device), you will ingest:
1 x 60 = 60metric datapoints per hour1 x 60 x 24 = 1,440metric data points per day1 x 60 x 24 x 365 = 525,600metric data points per day
Logs
This extension also ingests trap events as logs. To calculate consumption, refer to the appropriate section according to your license model:
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.
Events
| Metric name | Metric key | Description |
|---|---|---|
| Traps count | com.dynatrace.extension.snmp-traps-generic.traps.count | Number of traps received. |
