.SYNOPSIS
|
|
Windows ADFS Prometheus Metrics Exporter
|
|
.DESCRIPTION
|
|
Prometheus exporter for Active Directory Federation Services - token request
|
|
counts, authentication success/failure, relying party trusts, certificate
|
|
expiry, extranet lockout events, and WAP health. Exports metrics as
|
|
Prometheus-compatible text format.
|
|
.PARAMETER Mode
|
|
Output mode: 'stdout' (default), 'textfile', or 'http'
|
|
.PARAMETER Port
|
|
HTTP port for http mode (default: 9635)
|
|
.PARAMETER TextfileDir
|
|
Directory for textfile collector output (default: C:\ProgramData\node_exporter)
|
|
.PARAMETER InstallScheduledTask
|
|
Switch to create a scheduled task for auto-start on system boot
|
|
.PARAMETER TaskIntervalMinutes
|
|
Interval in minutes for the scheduled task (default: 2)
