cron snippet (Linux / macOS) bash

One-line crontab entry that runs heartbeat.sh every 5 minutes. Add via `crontab -e`.

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.)

# Every 5 minutes — site1.erralert.com heartbeat.
# Output silenced; failures still surface via capture.freshness on the server.
*/5 * * * * /opt/alerts/heartbeat.sh > /dev/null 2>&1

Recommended pairing

Add a capture.freshness check to this capture object.
Pair with max_silence ~10 min so a single missed cron pass still alerts.

What is the filename?

crontab-snippet.txt — this is the suggested name for the downloaded file. Rename freely if you prefer.
