This section shows the process for displaying system level information. The process consists of the following steps:

1. Authentication with PowerFlex Manager
2. Set the PowerFlex system name variable
3. Make a call to /api/types/System/instances/action/queryIdByKey endpoint using the PowerFlex system name variable in the body of the POST
4. Make a call to the /api/instances/System endpoint and pass the System ID.
5. Convert the output to JSON and write the output to a json file.

Authentication

Use the following code to authenticate with PowerFlex Manager and initialize variables.

#PFMP ingress

$PFMPhost = 'pfxm.powerflex.lab'

#System name

$SystemName = 'block-legacy-gateway'

#Authentication

$Headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"

$Headers.Add("Content-Type", "application/json")

$Headers.Add("Accept", "application/json")

$CredJson = "{`"username`": `"admin`", `"password`": `"Password`"}"

$Response = Invoke-RestMethod "https://$PFMPhost/rest/auth/login" -Method POST -Headers $Headers -Body $CredJson

$accessToken = $Response.access_token

#Create authentication header for use in API calls

$AuthHeader = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"

$AuthHeader.Add("Content-Type", "application/json")

$AuthHeader.Add("Accept", "application/json")

$AuthHeader.Add("Authorization", "Bearer $accessToken")

Get system id

The following code takes the PowerFlex system name defined in the $SystemName variable and queries for the system id.

#API Call for PowerFlex system id using the user entered system name

$SystemJson = "{`"name`":`"$SystemName`"}"

$SystemID = (Invoke-RestMethod -Uri "https://$PFMPhost/api/types/System/instances/action/queryIdByKey" -Method Post -Body $SystemJson -Headers $AuthHeader)

Get system information and write to file

Use the following code to get information for the PowerFlex system and save it to a file in JSON format.

#API call for PowerFlex system using the $SystemID variable

$SystemInfo = (Invoke-RestMethod -Uri "https://$PFMPhost/api/instances/System::$SystemID" -Headers $AuthHeader)

#Convert object to JSON and write to file.

$SystemInfo | ConvertTo-Json -Depth 4 | Set-Content -Path "C:\Users\Administrator\Desktop\PFsystem.json"
