CronPing Use Cases
See how developers use CronPing to monitor critical tasks and prevent silent failures
Database Backups
The Problem: Your nightly database backup runs at 2 AM. If it fails, you won't know until it's too late — potentially losing days of customer data.
The Solution: Add a single curl command to your backup script. If the backup fails or doesn't complete, CronPing alerts you immediately via email, Slack, or SMS.
Key Benefits:
- Never lose data due to silent backup failures
- Get alerted within 60 seconds of a missed backup
- Track backup history and success rates
- Peace of mind for compliance requirements
#!/bin/bash
# backup.sh - Nightly PostgreSQL backup
# Run backup
pg_dump -U postgres mydb > /backups/mydb_$(date +%Y%m%d).sql
# If backup succeeded, ping CronPing
if [ $? -eq 0 ]; then
curl -m 10 --retry 5 https://cronping.io/ping/abc123xyz
fiETL & Data Pipelines
The Problem: Your daily ETL job pulls data from APIs, transforms it, and loads into your warehouse. When it breaks, your analytics dashboard shows stale data and nobody notices for days.
The Solution: Monitor each stage of your pipeline with CronPing. Get instant alerts when data extraction, transformation, or loading fails.
Key Benefits:
- Catch pipeline failures before they affect business decisions
- Monitor each pipeline stage independently
- Reduce mean time to recovery (MTTR)
- Keep stakeholders informed with status pages
# etl_pipeline.py
import requests
import logging
def run_etl():
try:
# Extract data from API
data = extract_from_api()
# Transform data
transformed = transform_data(data)
# Load into warehouse
load_to_warehouse(transformed)
# Success! Ping CronPing
requests.get('https://cronping.io/ping/xyz789abc', timeout=10)
logging.info('ETL completed successfully')
except Exception as e:
logging.error(f'ETL failed: {e}')
# Don't ping CronPing - alert will trigger
if __name__ == '__main__':
run_etl()Server Maintenance Tasks
The Problem: Log rotation, disk cleanup, certificate renewals, and system updates run automatically. When they fail, disk space fills up or certificates expire, causing outages.
The Solution: Wrap maintenance scripts with CronPing monitoring. Get proactive alerts before small issues become production incidents.
Key Benefits:
- Prevent disk space outages from failed cleanup jobs
- Track maintenance task completion history
- Ensure compliance with scheduled maintenance windows
- Reduce emergency on-call incidents
#!/bin/bash
# cleanup.sh - Weekly disk cleanup
# Clean old logs
find /var/log -name "*.log" -mtime +30 -delete
# Clean temp files
find /tmp -type f -mtime +7 -delete
# Clean old Docker images
docker image prune -a --force --filter "until=168h"
# Ping CronPing on success

The Problem: Your marketing automation sends weekly newsletters, abandoned cart reminders, or digest emails. If the job silently fails, you miss revenue opportunities and customer engagement drops.
The Solution: Monitor your email jobs with CronPing. Know immediately if newsletters fail to send, ensuring consistent customer communication.
Key Benefits:
- Never miss a scheduled campaign send
- Track email job reliability over time
- Maintain consistent customer communication
- Protect revenue from abandoned cart reminders
// send-newsletter.js
const axios = require('axios');
const sendgrid = require('@sendgrid/mail');
async function sendWeeklyNewsletter() {
try {
// Get subscribers
const subscribers = await getSubscribers();
// Send newsletter
await sendgrid.sendMultiple({
to: subscribers,
from: 'newsletter@company.com',
templateId: 'd-xyz123',
});
console.log(`Sent to ${subscribers.length} subscribers`);
// Success - ping CronPing
await axios.get('https://cronping.io/ping/ghi789jkl');
} catch (error) {
console.error('Newsletter failed:', error);
process.exit(1); // Don't ping - alert will trigger
}
}
sendWeeklyNewsletter();SSL Certificate Renewals
The Problem: Let's Encrypt certificates auto-renew via cron. When renewal fails, your site becomes inaccessible and customers see scary security warnings, damaging trust and revenue.
The Solution: Monitor certbot renewal jobs with CronPing. Get advance warning before certificates expire, with time to fix renewal issues.
Key Benefits:
- Prevent website downtime from expired certificates
- Avoid customer trust issues from security warnings
- Ensure PCI compliance with valid certificates
- Sleep better knowing renewals are monitored
#!/bin/bash
# certbot-renew.sh - SSL certificate renewal
# Attempt to renew certificates
certbot renew --quiet --deploy-hook "systemctl reload nginx"
# Check if renewal succeeded
if [ $? -eq 0 ]; then
echo "Certificates renewed successfully"
curl https://cronping.io/ping/jkl123mno
else
echo "Certificate renewal failed!"
exit 1
fiWebsite Health Checks
The Problem: You want to ensure your website, API, or service is accessible and returning correct responses. Manual checks are tedious and you need automated monitoring.
The Solution: Create a simple cron job that checks your endpoints and pings CronPing on success. Get alerted if health checks fail.
Key Benefits:
- Monitor uptime without complex tools
- Verify APIs return expected responses
- Check multi-step workflows (login, checkout, etc.)
- Complement existing monitoring with custom checks
#!/bin/bash
# health-check.sh - Every 5 minutes
# Check if website is up and returns 200
HTTP_CODE=$(curl -o /dev/null -s -w "%{http_code}" https://myapp.com/health)
if [ "$HTTP_CODE" -eq 200 ]; then
# Site is healthy - ping CronPing
curl https://cronping.io/ping/mno456pqr
else
echo "Health check failed with code: $HTTP_CODE"
exit 1
