Understanding Response Time Charts

Understanding Response Time Charts

Response time charts show how quickly your monitored sites are responding over time.

Reading the Chart

  • X-axis — time (varies based on selected period)
  • Y-axis — response time in milliseconds (ms)
  • Each line — represents one monitor's response time trend

Interacting with Charts

  • Hover over the chart to see exact values at any point in time
  • Click legend items to toggle individual monitors on or off
  • Hidden monitors appear with a greyed-out, strikethrough label in the legend
  • The Y-axis automatically rescales when you toggle monitors, so you can focus on specific ones

What Response Times Mean

Response Time Rating
Under 200ms Excellent
200-500ms Good
500ms-1s Acceptable
1s-3s Slow
Over 3s Poor — investigate

Tips

  • Sudden spikes often indicate server load issues or network problems
  • Gradual increases may suggest growing database queries or memory leaks
  • Consistent high times from one region may indicate geographic latency
