Pure Replicated Arrays Test

The FlashArray enables connecting two arrays to provide high availability and data protection, and to prevent single point of failure. When the arrays are connected, the array where the data is being transferred from is called the source array, and the array where data is being transferred to is called the target array. After two arrays are connected, the target array must allow the connection from the source array to accept the data being transferred. If the connection is not established or lost between the arrays, the data will not be transferred to the target array. The very purpose of the high availability and data protection of the arrays may therefore, be defeated. To prevent such eventualities, administrators should continuously monitor the connection status between the source and target arrays. To achieve this, administrators can use the Pure Replicated Arrays test.

Target of the test : Pure Storage FlashArray

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the FlashArray being monitored.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
Port	The port at which the device listens. By default, this will be NULL.
API Token	The eG agent collects the required metrics from the Pure Storage Flash Array by executing API commands using Pure Storage REST API on the FlashArray and pulls out critical metrics. In order to collect metrics, the eG agent should be provided with a valid API token. To know how to determine the API token, refer to Pre-requisites for Monitoring the Pure Storage FlashArray. Specify the determined API token in the API Token text box.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 2:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Replicated Array Connection Status	Indicates the connection status of the replicated array.		The values reported by this measure and its numeric equivalents are mentioned in the table below: Measure value Numeric Value Connected 100 Not connected 0 Note: By default, this measure reports the Measure Values listed in the table above to indicate whether the replicated array is connected or not. The graph of this measure however is represented using the numeric equivalents only - 0 or 100. The detailed diagnosis of this measure reveals the name, ID and type of the replicated array.
