You can only improve what you measure. But too many metrics drown the essentials. This guide helps you identify the truly important indicators.
These metrics form the minimum dashboard to understand your services' health and measure your progress.
MoniTao automatically calculates most of these metrics. Focus on analysis and improvement, not collection.

Frequently Asked Questions
What's the most important metric?
Uptime for availability, MTTR for operations. But it's the combination that matters.
How to reduce MTTD?
Finer monitoring, more sensitive alerts, content verification. MoniTao can check every minute.
How to reduce MTTR?
Runbooks, automation, trained team, regular postmortems. MTTR drops with documented experience.
What to do about low MTBF?
Analyze root causes. Frequent incidents indicate a systemic problem to solve.
Should I measure p99 latency?
Yes. P50 hides extreme cases. 1% of slow requests can impact many users.
How to avoid false positives?
Well-calibrated thresholds, double verification before alerting, monitoring from multiple regions.
