Your users know when your site is down. The question is whether you find out from your monitoring system or from angry tweets. Uptime monitoring answers the most basic question in operations: is it working?
Networks are invisible until they break—then nothing else matters. Network monitoring watches the paths between systems so you can find problems before users do.
Your application runs on something. Servers, networks, disks—the invisible foundation that either holds steady or crumbles. Infrastructure monitoring lets you see what's happening beneath your code before it becomes your code's problem.
Your servers can report perfect health while users suffer. APM reveals what infrastructure metrics hide: where time actually goes when a human clicks a button and waits.
Logs capture the stories metrics can't tell—the specific errors, the exact sequence, the context that turns 'something broke' into 'here's what happened and why.'
Traditional monitoring asks 'is this working?' Security monitoring asks 'is someone hiding in here?' The difference shapes everything—from what you watch to how you interpret silence.
Your site could be broken right now. Synthetic monitoring runs scripted tests around the clock to find problems before your customers do.
Real User Monitoring captures what actually happens when real people use your application—the slow loads on budget phones, the rage clicks on unresponsive buttons, the errors that only appear in Safari. It's the difference between knowing your kitchen is clean and knowing your customers enjoy the meal.
