Arista extension
- Latest Dynatrace
- Extension
- Published Aug 10, 2026
Monitor your Arista devices using SNMP to track interface health, bandwidth, and CPU/memory usage to detect performance issues and resource exhaustion.
Get started
Overview
The Arista extension uses SNMP to gather performance and health metrics from your Arista devices every minute. This data is integrated into 
Infrastructure & Operations to offer Network and Ops Administrators visibility into device health and performance.
Use cases
- Identify problematic interfaces that drop or corrupt packets.
- Pinpoint hardware faults, misconfigurations, or congestion issues affecting performance or reliability down to the TCP/UDP level.
- Track real-time and historical bandwidth usage to analyze traffic patterns.
- Monitor CPU and memory consumption on Arista devices to detect memory leaks or resource exhaustion.
Compatibility information
- SNMP v2c or SNMP v3
- Dynatrace version 1.341+
- ActiveGate version 1.333+
Activation and setup
Activate the extension in your environment web UI using Dynatrace Hub. Provide the necessary device configuration, and Dynatrace automatically deploys the extension and begins monitoring.
Read more in our SNMP extension documentation.
Details
The extension package contains:
- SNMP data source configuration for metric ingestion
- Topology definitions for Arista devices
- Dashboards offering monitoring overviews
- Infrastructure & Operations entries for each created entity
The extension builds on the SNMP data source that is part of Dynatrace's Extensions 2.0 framework.
Licensing and costs
There is no charge to use the extension. You are only charged for the data that the extension ingests.
The Arista extension ingests custom metrics, which consume Davis Data Units (DDUs) (Dynatrace classic license) or Metrics powered by Grail (DPS), according to your license model.
Calculations are based on the assumption that you monitor only recommended metrics for every feature set every minute. Metric data points per minute per device:
8.2 + (9 * n_interfaces)
Dynatrace Platform Subscription
In the Dynatrace Platform Subscription, metric ingestion consumes Metrics powered by Grail according to the number of ingested metric data points.
To calculate the approximate yearly consumption, apply the following calculation: <metric data points per minute> * 60 minutes * 24 hours * 365 days.
Dynatrace classic license
In the classic licensing model, metric ingestion consumes 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.
The DDU cost above does not include any possible log events or custom events that are triggered by the extension. For more information, see DDU events.
Feature sets
When activating your extension using a 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.
