Dell PowerStore extension
- Latest Dynatrace
- Extension
Monitor performance and health of Dell PowerStore arrays by ingesting metrics for clusters, appliances, volumes, and filesystems via the Dell PowerStore API.
The Dell PowerStore extension connects to the Dell PowerStore API through a Dynatrace ActiveGate, builds an entity topology for clusters, appliances, volumes, filesystems, NAS servers, and SMB/NFS shares, and surfaces performance anomalies in unified analysis views.
Get started
Overview
The extension runs as a Python module on an ActiveGate.
Use cases
- Analyze PowerStore storage performance and health using entity-specific unified analysis views
- Receive alerts on performance and health issues detected in your PowerStore infrastructure
- Take proactive actions based on anomalies detected in your PowerStore infrastructure before they affect your applications
Requirements
- A Dell PowerStore array with the REST API accessible from an ActiveGate in your Dynatrace environment.
- PowerStore API connection details: server IP, username, and password.
Activation and setup
Activate the extension via the in-product Hub, then provide the PowerStore connection details and a user account. The account needs the Operator role, which provides read-only access to the PowerStore APIs.
Details
The extension package contains:
- Python module for metric ingestion from the PowerStore API
- Entity topology model for physical and logical PowerStore entities
- Pre-built dashboard for PowerStore monitoring overview
- Unified analysis views for each entity type
The extension monitors the following entities:
- Cluster
- Appliance
- Volume
- Filesystem
- NAS Server
- SMB-Share
- NFS-Export
Licensing and costs
There is no charge to use the extension. You are only charged for the data that the extension ingests.
The Dell PowerStore extension ingests custom metrics, which consume Davis Data Units (DDUs) (Dynatrace classic license) or Metrics powered by Grail (DPS), according to your license model.
The following formula provides approximate data points ingested per <Metrics Collection Interval>, assuming all feature sets are enabled. This extension does not ingest logs.
( 4 * number of Clusters)+ ( 10 * number of Appliances)+ ( 8 * number of Volumes)+ ( 8 * number of Filesystems)+ ( 7 * number of NAS Servers)+ ( 5 * number of SMB-Shares)+ ( 7 * number of NFS-Exports)
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.
