Legend¶
Click the Legend button in the bottom-left corner to see the meaning of the current lines, circles, and colors.
Services are represented by circles, and the color of the circle indicates the health status of the service:
- Healthy (Gray): Error rate = 0 and latency does not exceed 100 ms.
- Warning (Orange): 0 < Error rate <= 5% or 100 ms < Latency <= 200 ms.
- Critical (Red): Error rate > 5% or latency > 200 ms.
- Unknown (Dotted Line): No metric data available.
Service Metrics Information¶
Click any service to open a sidebar that displays relevant metrics based on the protocol type:
- HTTP Protocol: Error Rate (%), Request Rate (RPM), Average Latency (ms)
- TCP Protocol: Connection Count, Receive Throughput (B/s), Send Throughput (B/s)
