Production Monitoring Checklist: 10 Things Before Going to Production

Production Monitoring Checklist: 10 Things Before Going to Production

I’ve seen 3 production agent deployments fail this month. All 3 made the same 5 mistakes. Production monitoring is crucial, and skipping even one step could lead to major headaches down the line. So, here’s a checklist of the 10 things you must consider before going to production.

1. Set Up Application Performance Monitoring (APM)

APM tools give you real-time insights into your application’s performance. It’s essential to know where your application may struggle under load.

# Sample APM configuration for New Relic
newrelic.config.file: "/etc/newrelic/newrelic.cfg"

If you skip this step, you’ll be blind to performance issues, resulting in unhappy users and costly downtime. Do this today.

2. Implement Log Monitoring

Logs provide a window into the behavior of your application. Efficient log monitoring allows you to identify issues before they escalate.

import logging

logging.basicConfig(level=logging.DEBUG, 
 format='%(asctime)s - %(levelname)s - %(message)s')

If you skip log monitoring, diagnosing issues after the fact will be like finding a needle in a haystack. Do this today.

3. Set Up Alerting Mechanisms

You must know when things go wrong. Setting up alerts helps you to react before users start to feel the impact.

# Example of an alert configuration in Prometheus
groups:
- name: example
 rules:
 - alert: HighMemoryUsage
 expr: process_resident_memory_bytes > 500000000
 for: 5m
 labels:
 severity: page

Skipping alerts means you’ll be running around like a headless chicken when something breaks. Do this today.

4. Monitor Database Performance

Database problems can kill your app’s performance. Keeping an eye on query times and slow queries is essential.

# MySQL slow query log
SET GLOBAL slow_query_log = 'ON';

Neglecting this could lead to slow response times or crashes, as users get frustrated waiting. Do this today.

5. Ensure Proper Resource Monitoring

Monitoring resources (CPU, memory, disk) is a no-brainer. Without this, you’ll miss the signs of impending resource exhaustion.

# Shell command for checking CPU usage
top -b -n1 | grep "Cpu(s)"

If you ignore resource monitoring, well, good luck handling sudden spikes in traffic. Do this today.

6. Assess Security Monitoring

Security is not optional. Understanding if your app has vulnerabilities or unusual activities is crucial.

# Example configuration for OSSEC

 yes

Skipping security monitoring can bring your whole system down due to a breach. Nice to have, but seriously, just do it.

7. Check Service Health Monitoring

Make sure that all third-party services you depend on are up and running. Downtime can cripple your app.

# Example of service check using cURL
curl -f https://thirdpartyapi.com/health

If external services fail, your app could fall behind. This one’s a nice-to-have.

8. Configure User Behavior Tracking

Knowing how users interact with your app can help you improve it. Implement user behavior tracking to gather insights.

analytics.track('Signup', {
 plan: 'Pro',
 accountId: '12345'
});

If you’re not tracking user behavior, you’re essentially driving blind. This is a nice-to-have, but don’t forget it.

9. Setup Website Uptime Monitoring

Website uptime should be your priority. Regular checks help you know if users can actually access your site.

# Example using cron job for uptime
* * * * * curl -f -s --retry 5 https://yourwebsite.com || echo "Website is down!" | mail -s "Uptime Alert" [email protected]

Ignoring website uptime means potentially losing customers. Make this a nice-to-have.

10. Review and Optimize Your Monitoring Strategy

Keep improving your monitoring processes. Technology and best practices change over time, so your strategy should too.

# Run this periodically to review monitoring setup
tail -n 100 /var/log/monitoring.log

Failing to optimize your monitoring strategy means you’re operating with outdated methods. This is essential to have, but easily neglected.

If You Only Do One Thing…

If you take away just one task from this checklist, it should be implementing application performance monitoring (APM). Why? Because your app’s performance has a direct impact on user satisfaction and retention. You can improve logs, security, and everything else later, but if your application is slow or failing, nothing else matters. Trust me, I learned this the hard way – launching an app without monitoring led to a meltdown and a lot of angry users, and nobody wants to relive that disaster.

Frequently Asked Questions

What should I monitor for web applications?

Focus on performance metrics (latency and throughput), error rates, uptime, resource usage (CPU, memory), and user behavior.

How often should I review my monitoring setup?

At least once a quarter. As your app and user base grow, requirements will change.

Why does monitoring matter in production?

Monitoring helps you catch issues early, improving user experiences and helping prevent outages, which are costly.

Can I manage monitoring without third-party tools?

Yes, but it requires a lot of effort from your team. Home-grown solutions are often less reliable.

Are there any free monitoring tools?

Absolutely! Tools like Prometheus and Grafana are open-source and provide excellent capabilities without cost.
