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
