LATENCY GRAPH draws the spikes recorded for one event as a text chart you can read in a terminal: a heading with the highest and lowest spike shown and the all-time worst, then one bar per spike, oldest first, labelled with how long ago it happened and its duration. Bars are scaled to the highest spike shown. The event name is case-sensitive.

Return value

Section titled “Return value”

The chart as text: a bulk string in RESP2, a verbatim string (txt) in RESP3. An event with no spikes, or an unknown name, gets ERR No samples available for event '<event>'.

Redis 7 and Valkey 8 have the same command but draw a different chart (vertical, with time on the horizontal axis). Use LATENCY HISTORY if you need the numbers.
