Monitoring Basics for Owners Without a DevOps Team | Operations And Monitoring Field Guide

Your server went down at 9pm. Nobody noticed until the office opened at 8am. That's 11 hours of downtime. Eleven hours of no email, no customer orders, no nothing.

This happens because businesses don't monitor their systems. They wait for someone to complain.

Monitoring fixes this. It tells you when things break before your customers do.

What this solves

Faster problem detection. Find out about issues before customers report them.

Reduced downtime. Quick detection means quicker fixes.

Historical context for troubleshooting. What happened? When? Why? Monitoring data answers these questions.

Visibility into system health. Are things getting worse over time? Is a hard drive failing? Is bandwidth maxed out?

Accountability. Someone broke something at 3am. Monitoring shows who and what.

What can go wrong

No monitoring at all. Systems fail silently. Customers call to complain. You have no idea what happened.

Too many alerts. You get 500 emails a day about non-issues. You start ignoring everything. Real problems get lost.

Nobody watching the alerts. Monitoring without someone responsible for responding is just expensive logging.

Monitoring that only checks if systems are up. You're watching the gauges but not the engine. A server can be "up" but performing so poorly it might as well be down.

Vendor monitoring gaps. "The vendor is monitoring it" might mean they're watching their own dashboards, not yours.

What you should be monitoring

Server health:

CPU usage
Memory usage
Disk space and disk health (SMART status)
Temperature (if applicable)
Service status (is the database running? The web server?)

Network:

Bandwidth utilization
Uptime of firewalls, switches, routers
VPN connections
DNS resolution

Applications:

Are your key applications responding?
Response times
Error rates
Database connections

Security:

Failed login attempts
Unusual outbound traffic
Firewall blocks
Antivirus status

What it costs (honest ranges)

DIY monitoring (built-in tools, scripts): $0 in software, but requires time to set up and maintain.

Uptime monitoring services (UptimeRobot, Pingdom): $10-$50/month for basic HTTP and port monitoring. Catches "totally down" but not "slowly dying."

Comprehensive monitoring tools (Datadog, New Relic, SolarWinds): $50-$500/month for small business. Depends on number of hosts and data retention.

MSP monitoring: Usually bundled into managed services, $500-$2,000/month for small business depending on environment.

Hidden cost of no monitoring: Average SMB pays $5,000-$50,000 per hour of preventable downtime. Eleven hours (like the example above) could cost $55,000-$550,000.

Minimum viable implementation

Set up uptime monitoring. Use a free or cheap service to check if your public-facing systems are reachable. Get an alert when they're not.
Enable disk space alerts. Most server outages from "mysterious causes" are actually disk full. Set alerts at 80% and 90%.
Monitor backup completion. You have backups (right?). Make sure they're actually running. Set an alert for backup failures.
Check antivirus status daily. Make sure endpoints are reporting in and definitions are current.
Assign alert responsibility. Decide who gets called when an alert fires. Make sure that person knows what to do.

Vendor questions (copy/paste)

Ask your IT vendor or MSP:

What do you monitor in our environment?
What alerts do we get, and how?
Who responds to alerts outside business hours?
Can we see your monitoring dashboards?
What's your average time to respond to a monitoring alert?

Ask yourself:

Do I know when our systems go down?
Does anyone check the server on weekends?
When was the last time we had a problem that nobody noticed immediately?

When to hire help

You don't know what you're monitoring. A consultant can assess your environment and implement appropriate monitoring.

Alerts are being ignored. If monitoring exists but nobody acts on it, you need better processes or better tools.

You're growing. More systems mean more failure points. Monitoring needs to scale with you.

You've had unexplained outages. If you can't explain why something went down, you need better visibility.

Monitoring isn't about watching dashboards. It's about knowing something is wrong before your customers do. The goal is to fix problems during business hours, not discover them when customers call the next morning.
