Seq from Powershell POC

Example.ps1

Import-Module Seq

# Specify the Seq server URL; an -apiKey can also be provided.
# Any properties set here will be attached to all events.

$seq = Open-Seq "http://my-seq" -properties @{ Machine = $env:ComputerName }

# Simple information method

Send-SeqEvent $seq "Hello from PowerShell"

# Specify additional properties and a level value (Verbose, Debug, Warning, Error and Fatal are allowed)

Send-SeqEvent $seq "Something is broken!" -level Error -properties @{ User = $env:Username }

# Use the -template switch if the message is a Serilog-style template

Send-SeqEvent $seq "Leonard is {Age}" -properties @{ Age = 42 } -template

Seq.psm1

function Open-Seq ([string] $url, [string] $apiKey, $properties = @{})
{
  return @{ Url = $url; ApiKey = $apiKey; Properties = $properties.Clone() }
}

function Send-SeqEvent (
    $seq,
    [string] $text,
    [string] $level,
    $properties = @{},
    [switch] $template)
{
  if (-not $level)
  {
    $level = 'Information'
  }
  
  if (@('Verbose', 'Debug', 'Information', 'Warning', 'Error', 'Fatal') -notcontains $level)
  {
    $level = 'Information'
  }

  $allProperties = $seq["Properties"].Clone()
  $allProperties += $properties

  $messageTemplate = "{Text}"

  if ($template)
  {
    $messageTemplate = $text;
  }
  else
  {
    $allProperties += @{ Text = $text; }
  }

  $body = "{""Events"": [ {
    ""Timestamp"": ""$([System.DateTimeOffset]::Now.ToString('o'))"",
    ""Level"": ""$level"",
    ""MessageTemplate"": $($messageTemplate | ConvertTo-Json),
    ""Properties"": $($allProperties | ConvertTo-Json) }]}"

  $target = "$($seq["Url"])/api/events/raw?apiKey=$($seq["ApiKey"])"

  Invoke-RestMethod -Uri $target -Body $body -ContentType "application/json" -Method POST
}

I actually really like this. I might use this in something i was working on! :)

Awesome :) --- just added it to the Seq docs: https://getseq.atlassian.net/wiki/display/SEQ10/Writing+events+from+PowerShell --- patches/enhancements accepted!
