Stats and Measurements
Read Tunna stats and measurements for latency, RTT, packet loss, data usage, chart ranges, node quality, and ZAP readiness.
Use this page when a node row or stats screen shows values, dots, colors, or chart ranges you want to understand before switching nodes.
What the numbers mean
Use these cards as a map of the visible labels in this view. Each card names one field, control, or status item and explains what it is for before you change it or rely on it.
Visible choices
These are controls, states, or measurements in the view. Read them as reference, not as feature claims.
Latency
Latency is the wait time for the test trip. Smaller usually feels better. Green means quick, yellow and orange mean slower, red means failed or timed out.
Probing and Timeout
Probing means Tunna is still collecting enough samples. Timeout means the latest checks did not get useful answers.
Round Trip Time
The stats chart groups recent checks by Hour, Day, Month, or Year and shows average, high, low, middle, and slow-tail results.
Data Usage
Usage shows how much data the selected node sent and received, plus the transfer rate over the selected time range.
Observability colors are measurements; Log colors are messages
Latency colors summarize probe outcomes: green is quick, yellow and orange are slower, and red means failed or timed out. Log colors summarize message severity: gray None, red Error, yellow Warning, green Info, and blue Debug. Use Observability for health trends, then use Log when you need the text behind a failed test.
