Generic Cisco Device extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Monitor Cisco devices using SNMP to feed Dynatrace with metrics and alerts.
Get started
Overview
Cisco devices are a critical component in your network infrastructure. The Generic Cisco Device monitoring extension allows for remote monitoring of your Cisco network devices via the Simple Network Management Protocol (SNMP).
Use cases
- Monitor resource usage of network components
- Detect and alert on issues with critical protocols such as BGP
- Identify problems with network interfaces
Requirements
- Minimum Dynatrace environment and ActiveGate version 1.310
- ActiveGate must be able to communicate with the target devices via SNMP
- Review the SNMP data source documentation for details on support-levels and authentication
- The monitored devices must support a given Management Information Base (MIB) file in order to collect it's data
- Not all Cisco devices support all MIBs
- Some Cisco devices may only partially support a given MIB
Compatibility information
This extension is designed to generically provide visibility into a wide variety of Cisco network devices. Only products still supported by Cisco will be officially supported but it can be used to monitor any devices that meet the requirements for SNMP connectivity and support the MIBs and OIDs used.
Activation and setup
Find 'Generic Cisco Device' in the in-product Extensions App or Hub page and activate (if offline you can download the extension from the Hub page in the 'Release notes' section and install as a custom extension).
Monitoring configurations
You can add multiple target devices to a given monitoring configuration (recommended). Review the SNMP data source documentation for details on the configuration fields for SNMP device monitoring.
After adding the monitored devices you can select which feature sets to enable which will determine what the extension will query for.
Details
Metrics
Review the list of feature sets to see which metrics are collected. Not all feature sets will be applicable to all devices. You can enable or disable feature sets as needed based on the types and versions of devices you are using and your unique monitoring requirements.
Some metrics are required and cannot be disabled. These metrics will be in the "default" feature set. Take extra caution configuring devices and interfaces for which you are collecting data. Make use of Interface filters to limit the number of interfaces, otherwise, all interfaces on the device will be collected.
In case you do not wish to collect interfaces on your device, enter $eq(!) in the Interface filter field.
Licensing and cost
License consumption is based on the number of metric data points ingested. Below is a breakdown of metrics by feature set metrics collected once per minute.
There are two metrics in the default feature set that are collected at a 30 minute interval for the Generic SNMP Cisco Device entity and as such are not included due to a minimal impact on the estimation:
-
default: 20
- 7 x Generic Network Interface
- 3 x Generic Network Device
- 8 x Generic SNMP Cisco Device

Approximate yearly datapoints = <metrics> * 60 minutes * 24 hours * 365 days data points per year
Classic licensing
In the Dynatrace classic licensing model, metric ingestion will consume Davis Data Units (DDUs) at the rate of .001 DDUs per metric data point.
Multiply the above formula for annual data points by .001 to estimate annual DDU usage.
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.
