Overview

Monitor your Pure Storage FlashArray fleet using this Dynatrace Extension 2.0 and the Pure Storage FlashArray OpenMetrics exporter. The integration can provide performance data at the array, host, volume and pod level, as well as high-level capacity and configuration information. Monitor multiple FlashArrays and aggregate these into a single dashboard, or group them together by customer defined environment. This integration requires the following: The Pure Storage OpenMetrics exporter is installed and running in a containerized environment. Refer to the GitHub repo for installation instructions. https://github.com/PureStorage-OpenConnect/pure-fa-openmetrics-exporter

This extension provides 2x integrated dashboards:

Pure Storage Overview (OpenMetrics) Dashboard

Monitor your fleet of FlashArrays in one simple view, displaying

Purity OS Version
Alerts & Criticality
Data Reduction Ratio
Capacity Utilization
Data Throughput
IOPS by type

Pure Storage Entity Overview Dashboard

Drill down into individual FlashArray configurations and components.

Feature Sets

Explore and select metrics from the following feature sets:

default (array details)
Alerts
Directories
Hosts
HW
Network Interfaces
Pods
Volumes

Use cases

This extension would be super useful for empowered Pure Storage Administrators and Site Reliability Engineers to capture metrics for FlashArray to utilize the awesome overview dashboard displaying high level fleet statistics and configuration.

Users will be able to:

View high level array configuration
Monitor performance metrics and configure alerts
Correlate FlashArray metrics with other platforms

Get started

To enable this extension, Dynatrace will need to connect to the Pure Storage OpenMetrics exporter. This exporter receives requests for exposed metric endpoints and sends the request to the FlashArray via the REST API client. The REST results are interpreted and sent back to Dynatrace in the OpenMetrics standard format for ingestion.

Please refer to Pure Storage OpenConnect GitHub repository for more information and the latest packages. https://github.com/PureStorage-OpenConnect/pure-fa-openmetrics-exporter

Check the compatibility section for latest information on specific Dynatrace prerequisites.

Details

NOTE: See Pure Storage OpenMetrics Exporter Configuration below for configuration dependencies. If using TLS, ensure URL is set to https. No further Dynatrace configuration is required if Skip ssl verification is enabled. Alternatively the ActiveGate will require the certificate to be added to the OS trust store and ActiveGate configuration.

Providing the Pure Storage FlashArray OpenMetrics Exporter has been deployed then the this extension can be configured.
At the top of this page, use the green button 'Add to environment'.
In the Configuration tab of the extension under the Versions section select Add monitoring configuration.
Monitoring source: Select Monitor remotely tab.
ActiveGates: Select the appropriate ActiveGate group and move to the Next step.

extension_select_activegates

Prometheus: Add configuration entries for each metric endpoint to be scraped. Refrain from scraping all metrics using /metrics as these are expensive queries in large environments.
1. Select 'Add endpoint' button.
2. URL: http://pure-ome-address:9490/metrics/array?endpoint=arrayname01
3. Authentication scheme: No authentication
4. Skip ssl verification: Enabled
Finaize configuration: Check config and select required metric feature sets to be ingested into Dynatrace and select Activate

extension_finalize_config

After a few minutes the configuration will appear with status Ok and metrics will be ingesting.

Metric Endpoints & Scrape Intervals

For performance metrics we wish to scrape as frequently as possible to

By default this extension scrape endpoints at predefined intervals as follows:

Feature Set	Device Metric Endpoint	Scrape Interval
default	/metrics/array	1 min
Alerts	/metrics/array	5 min
Directories	/metrics/directories	5 min
Hosts	/metrics/hosts	1 min
HW	/metrics/array	5 min
Pods	/metrics/pods	1 min
Volumes	/metrics/volumes	1 min

To customize these scrape intervals, contact your Dynatrace representative to configure a custom extension.

DDU Cost Calculation Per Array :

Information Needed:
- Number of Hosts
- Number of Pods
- Number of Volumes
- Number of NICs
- Number of Hardware Components
  - Number of Temp Sensors
  - Number of Power Supplies
- Number of Directories(Filesystems)

    (45 + (39 * Hosts) + (56 * Pods) + (38 * Volumes)) * 525.6)
    +
    ((10 * NICs) + Total Hardware Components + Temp Sensors + Power Supplies + (26 * Directories) + 2) * 105.12)
    = Total DDUs/Year for the one FlashArray

The first piece of the equation (45 + (39 * Hosts) + (56 * Pods) + (38 * Volumes)) * 525.6) are for metric polled every 1 minute

The second piece of the equation ((10 * NICs) + Total Hardware Components + Temp Sensors + Power Supplies + (26 * Directories) + 2) * 105.12) are for metrics polled every 5 minutes.

Compatibility information

Purity

Pure Storage FlashArray from Purity version 6.1.0 onwards. Some metrics may have been exposed in later versions of Purity REST API 2.x and Pure Storage OpenMetrics exporter.

Pure Storage OpenMetrics Exporter Configuration

Dynatrace requires secure connections when using any kind of authentication. Pure Storage OpenMetrics Exporter must be configured with either:

Insecure: http with API tokens.yaml file and no authentication
Secure: TLS https with bearer token

Dynatrace does not support Pure Storage OpenMetrics Exporter to be configured with standard http and bearer token.
