Code Examples

Basic ping

#!/bin/bash
# Add to end of any cron script

# Simple ping on success
curl -fsS --retry 3 https://haspulse.io/ping/YOUR_CHECK_ID

# With start signal
curl -fsS https://haspulse.io/ping/YOUR_CHECK_ID/start
# ... your script logic ...
curl -fsS https://haspulse.io/ping/YOUR_CHECK_ID

With error handling

#!/bin/bash
CHECK_URL="https://haspulse.io/ping/YOUR_CHECK_ID"

# Signal start
curl -fsS "$CHECK_URL/start"

# Run your job and capture exit code
/path/to/your/backup-script.sh
EXIT_CODE=$?

# Ping based on result
if [ $EXIT_CODE -eq 0 ]; then
    curl -fsS "$CHECK_URL"
else
    curl -fsS "$CHECK_URL/fail"
fi

exit $EXIT_CODE

How It Works

1
Create a check in Haspulse
Set your expected schedule (e.g., every 5 minutes)
2
Add the ping to your code
Ping the unique URL when your job runs successfully
3
Get alerted on failures
If a ping doesn't arrive on time, we notify you
