Learn how to use a website uptime checker to monitor your site around the clock. Compare tools, set up alerts, and ensure your website never goes down unnoticed.

False alerts waste time and erode trust. Learn what causes false downtime alerts and how to configure monitoring to minimize them without missing real issues.

99.9% uptime sounds impressive until you calculate the downtime. Learn what different uptime percentages actually mean and how to set realistic SLA targets.

A status page is a public webpage showing your service's current health. Learn what status pages do, when you need one, and how to set one up effectively.

Agent-based monitoring uses software installed on servers to collect metrics. Learn what it is, how it compares to agentless monitoring, and when to use each approach.

Agentless monitoring collects data without installing software on target systems. Learn how it works, when it's useful, and why it often fails for serious infrastructure monitoring.

Alert fatigue happens when too many alerts cause people to ignore them. Learn the causes, warning signs, and proven strategies to eliminate alert fatigue in your team.

Blackbox monitoring tests systems from the outside without knowing their internals. Learn how it works, when to use it, and how it complements whitebox monitoring.

A false positive alert is an alert that fires when there's no real problem. Learn why false positives happen, how they damage your incident response, and how to eliminate them.

Heartbeat monitoring tracks scheduled tasks by waiting for check-ins. If your cron job doesn't ping within the expected timeframe, you get alerted. Simple explanation with examples.

Infrastructure monitoring is the practice of collecting and analysing data from your servers, networks, and cloud resources to ensure they're healthy and performing well. Learn the basics.

Mean Time to Detect (MTTD) measures how long it takes to discover a problem after it starts. Learn how to calculate MTTD, why it matters, and how to improve it.

Mean Time to Resolve (MTTR) measures how long it takes to fix a problem completely. Learn how to calculate MTTR, what affects it, and strategies to reduce it.

A probe node is a server that performs health checks from a specific location. Learn how probe nodes work, why location matters, and how multi-location monitoring prevents false alerts.
