It can be very useful to see how many active connections you have on your SharePoint server. This can be easily done using PowerShell to look at the IIS performance counters.
As is mostly the case with scripting, somebody has already done a much better job than I ever could. Here is a script which creates a PowerShell function Get-WebServiceConnections.
I created a PowerShell script called CurrentConnections.ps1 with the following content and can now run it whenever needed:
function Get-WebServiceConnections()
{
$results = @{}
$perfmon = new-object System.Diagnostics.PerformanceCounter
$perfmon.CategoryName = "Web Service"
$perfmon.CounterName = "Current Connections"
$cat = new-object System.Diagnostics.PerformanceCounterCategory("Web Service")
$instances = $cat.GetInstanceNames()
foreach ($instance in $instances)
{
$perfmon.InstanceName = $instance
$results.Add($instance, $perfmon.NextValue())
}
write-output $results
}
Get-WebServiceConnections
