HP ICF Switch extension
- Latest Dynatrace
- Extension
Monitor your HP ICF switches using SNMP
Get started
Overview
The HPE ICF extension leverages SNMP to gather performance and health metrics from your ICF switches every minute. This data is seamlessly integrated into Dynatrace’s Infrastructure & Operations app, offering Network and Ops Administrators 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 ICF switches to detect potential leaks or resource exhaustion.
Compatibility information
- SNMP v2c or SNMP v3
- Dynatrace version 1.310+
- ActiveGate version 1.310+
Activation and setup
Activate the extension in your environment web-UI using the Dynatrace Hub. Simply provide the necessary device configuration, and Dynatrace will automatically deploy the extension and begin monitoring.
Read more in our SNMP extension documentation.
For full visibility, you must install the SNMP autodiscovery extension in your environment. Creating a monitoring configuration for it is not required.
Details
The extension package contains:
- SNMP data source configuration for metric ingestion
- Topology definitions for HPE ICF 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 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 HP ICF Switch 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 all metrics for every feature set every minute. Metric data points per minute per switch:
4 + (8 * 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.
