Batch / Cmd heartbeat batch

Download heartbeat.cmd

One-line heartbeat from cmd.exe — useful when you cannot enable PowerShell script execution. Calls powershell.exe inline to POST.

Placeholders only. Before running, replace YOUR_URL with your capture endpoint's POST URL . (Open this page from your capture object to have these auto-filled.)

@echo off
REM heartbeat.cmd — site1.erralert.com check-in from cmd.exe (no script-exec policy needed)
