As the title says, I wanted to create a new project in VSTS / Azure DevOps, whatever you want to call it. Here is the code to do that. You need a Personal Access Token to authenticate with.

$User="[email protected]"
$PAT="YourPAT"
$Organization="YourOrg"
$base64authinfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $User, $PAT)))
$url="https://dev.azure.com/$Organization/_apis/projects?api-version=5.1-preview.4"
$body = @"
{
  "name": "FabrikamTravel",
  "description": "Frabrikam travel app for Windows Phone",
  "capabilities": {
    "versioncontrol": {
      "sourceControlType": "Git"
    },
    "processTemplate": {
      "templateTypeId": "6b724908-ef14-45cf-84f8-768b5384da45"
    }
  }
}
"@
Invoke-RestMethod -Method POST -ContentType application/json -Uri $url -Headers @{Authorization=("Basic {0}" -f $base64authinfo)} -Body $Body

Hope that helps someone?

I wanted to pull some data out of Azure Log Analytics using PowerShell and the REST API. Here is the code to Pull all errors in the Application event logs on VMs that are pushing their logs into Log Analytics via MicrosoftMonitoringAgent.

Hopefully this may help someone:

$SubscriptionId = "$($env:SubscriptionId)"
$TenantId       = "$($env:TenantId)" 
$ClientID       = "$($env:ClientID)"      
$ClientSecret   = "$($env:ClientSecret)"  
$TenantDomain   = "$($env:TenantDomain)" 
$loginURL       = "https://login.microsoftonline.com/$TenantId/oauth2/token"
$resource       = "https://api.loganalytics.io"         

$body           = @{grant_type="client_credentials";resource=$resource;client_id=$ClientID;client_secret=$ClientSecret}
$oauth          = Invoke-RestMethod -Method Post -Uri $loginURL -Body $body
$headerParams = @{'Authorization'="$($oauth.token_type) $($oauth.access_token)"}

$Workspacename="Your WS Name"
$WorkspaceId="Your WS ID"

$url="https://api.loganalytics.io/v1/workspaces/$WorkspaceId/query"
$body = @{query = 'Event | where EventLog == "Application" | order by TimeGenerated asc | project Computer,EventLog,Source,EventLevelName,EventID,RenderedDescription,TimeGenerated'} | ConvertTo-Json
$webresults=Invoke-RestMethod -UseBasicParsing -Headers $headerParams -Uri $url -Method Post -Body $body -ContentType "application/json"

Notes:

1. I keep my subscription information in Env Varaibles. It is easier for me to swtich to a different Tenant
2.  This returns the results in tables. To move the tables into an object look at this person’s code at line 60  https://blog.tyang.org/2017/11/14/searching-oms-using-the-new-search-language-kusto-rest-api-in-powershell/
3. My interpretation of code in #2

$resultsTable=$webresults.Content | ConvertFrom-Json
$count = 0
foreach ($table in $resultsTable.Tables) {
$count += $table.Rows.Count
}
$results = New-Object object[] $count
$i = 0;
foreach ($table in $resultsTable.Tables) {
    foreach ($row in $table.Rows) {
        # Create a dictionary of properties
        $properties = @{}
        for ($columnNum=0; $columnNum -lt $table.Columns.Count; $columnNum++) {
            $properties[$table.Columns[$columnNum].name] = $row[$columnNum]
        }      
        $results[$i] = (New-Object PSObject -Property $properties)
        $null = $i++
    }
}
$results

I have been provisioning machines over an over trying to learn all the VM Extensions. One of the extensions that I have been playing with is the DSC extension. Every time I provision with this extension, it adds an additional record into the State Configuration, resulting in many stale machines. I wanted to clear out all the old machines. I couldn’t find a way to do it in PowerShell, so I figure out how to do it via the REST API (and PowerShell).

Here is the code to remove all machines from Azure State Configuration (DSC)

$SubscriptionId = "$($env:SubscriptionId)"
$TenantId       = "$($env:TenantId)" 
$ClientID       = "$($env:ClientID)"      
$ClientSecret   = "$($env:ClientSecret)"  
$TenantDomain   = "$($env:TenantDomain)" 
$loginURL       = "https://login.microsoftonline.com/$TenantId/oauth2/token"
$resource       = "https://management.core.windows.net/"    
$resourceGroupName = "YourResourceGroupName "
$automationAccountsName ="YourAutomationAccountsName "

# get the OAUTH token & prepare header
$body           = @{grant_type="client_credentials";resource=$resource;client_id=$ClientID;client_secret=$ClientSecret}
$oauth          = Invoke-RestMethod -Method Post -Uri $loginURL -Body $body
$headerParams = @{'Authorization'="$($oauth.token_type) $($oauth.access_token)"}

# main query to find all the nodes
$url="https://management.azure.com/subscriptions/$SubscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Automation/automationAccounts/$automationAccountsName/nodes?api-version=2018-01-15"
$results=Invoke-RestMethod -Uri $url -Headers $headerParams -Method Get
# Loop through all the nodes and delete them all.
foreach ($node in $($results.value | Select-Object  -ExpandProperty properties | Select nodeid)){
$url="https://management.azure.com/subscriptions/$SubscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Automation/automationAccounts/$automationAccountsName/nodes/$($node.nodeId)?api-version=2018-01-15"
Invoke-RestMethod -Uri $url -Headers $headerParams -Method Delete
}

Notes:

1. I put all my SPN info into environmental varaibles (easier to switch of needed)
2. Put in your RG name and Auutomation Account Name
3. Warning. This will delete all nodes!
