Pure Storage FlashArray Monitoring

Pure Storage FlashArray develops all-flash data storage hardware and software products. LogicMonitor offers a suite to monitor performance statistics for Pure Storage arrays.

Compatibility

• The LogicModules in this package use the Pure Storage REST API. Refer to their documentation here.
• Overall array performance statistics are extracted using SNMP. Configuring only SNMP requires the module: PureStorage_Performance.

Setup Requirements

You will need a new or existing user with read-only access to the device. Depending on your PureStorage FlashArray configuration, this may be created locally on the device itself or externally through an Active Directory or LDAP integration.

Credentials

Create an API Token for the account using the Purity GUI or the CLI.

• In the Purity GUI, go to System > Users > Create API Token
• On the CLI, run the command: pureadmin create --api-token

Your token should look like: 523eb429-7432-3425-bb12-5fe45ba66416

Role	Description
purestorage.apitoken.pass	Pure Storage API token

Associate your PureStorage API Token with your device by adding it as a device property of the name purestorage.apitoken.pass. Refer to Pure Storage’s documentation for creating tokens here.

Ports

Enter the port(s) used by the technology suite.

Protocol	Ports	Description
TCP	443	REST service access
UDP	161	SNMP (Optional)

Considerations

The following PropertySources must be installed for modules in this package to work:

• addCategory_PureStorage
• PureStorage_ArrayInfo
• PureStorage_API_Versions​

Troubleshooting

This package contains a Troubleshooting module that should only be visible if there is a problem during setup. If there is a problem, the module should create a troubleshooting instance displaying problems.

Examples of setup issues include bad credentials or incompatible API versions (such as for older equipment).

LogicModules in Package

LogicMonitor’s package for Pure Storage FlashArray contains the following LogicModules. Please ensure that all of these LogicModules are imported into your LogicMonitor platform.

Name	Type	Description
addCategory_PureStorage	PropertySource	Adds system.categories=PureStorage to devices that return a login page when queried.
addERI_PureStorage	PropertySource	Sets Pure Storage ERI and StorageNode ERT for topology mapping purposes.
Volume Utilization	DataSource	PureStorage Volume Utilization as provided by REST API. Some systems do not return shared_space.
Volume Performance (Older API versions)	DataSource	PureStorage Volume Performance as provided by REST API.
Volume Performance	DataSource	PureStorage Volume Performance as provided by REST API.
Temperature Sensors	DataSource	PureStorage Temperature Status as provided by REST API.
PureStorage_ArrayInfo	PropertySource	Kept separate from the basic addCategory_PureStorage PropertySource deliberately.
PureStorage_API_Versions	PropertySource	Kept separate from the basic addCategory_PureStorage PropertySource deliberately. Finds supported API versions – mostly for possible future reference if data outputs change or versions are removed.
PureStorage Troubleshooter	DataSource	Visible if there is a problem with setup.
Drive Status	DataSource	PureStorage Array Performance as provided by REST API. Some systems do not return a ‘degraded’ value.
Component Status	DataSource	PureStorage Component Status as provided by REST API.
Array Utilization	DataSource	PureStorage Array Utilization as provided by REST API. Parity will be NaN if API is v1.7 or below.
Array Performance SNMP	DataSource	PureStorage Array Performance via SNMP.
Array Performance	DataSource	PureStorage Array Performance as provided by REST API. san_usec_per_read_op, san_usec_per_write_op will be NaN if API is v1.9 or below.
Array Controllers	DataSource	PureStorage Array Controller status as provided by REST API.
PureStorage_Topology	TopologySource	Generate Pure Storage topologies.

When setting static datapoint thresholds on the various metrics tracked by this package, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment.
