Overview

SNMP traps can be used to gain more details about the health state of your network devices. By adding event-based data to all the metrics reported in combination with dedicated SNMP extensions, you are able to diagnose the performance and availability issues even better.

Use cases

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 explaining metric anomalies
Unified visibility for metrics and traps

Get started

Simply enable the extension and configure your device, so that SNMP traps can reach the Dynatrace SNMP listener.

Details

This extension package contains:

Topology for SNMP Trap Devices that is derived from the IP address of the agent sending the traps.
A dashboard offering a monitoring overview for 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. This can be turned on or off by toggling the Events feature set in the monitoring configuration.

Compatibility information

SNMPv1, SNMPv2(c) and SNMPv3 support
No event forwarding

License Consumption

This extension collects a count of SNMP traps every minute. Once data is produced, this is ingested as metric datapoints and subject to license consumption. Whether you are on a Classic or DPS license model, 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 which gives you a number of metrics per feature set and 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.

Events 1 x SNMP Traps Devices

Assuming there is 1 SNMP Trap Device being monitored (1 metric x 1 SNMP Trap Device), it will ingest:

1 x 60 = 60 metric datapoints per hour
1 x 60 x 24 = 1,440 metric data points per day
1 x 60 x 24 x 365 = 525,600 metric data points per day

This extension also ingests trap events as logs. To calculate consumption, refer to the documentation depending on your licensing:

Troubleshooting

To troubleshoot this extension, use the guide in the Dynatrace Documentation.
