💖 latency-latest — the 3valkey manual page, but make it cute ✨

okay bestie, pull up a chair 🫶 this is a page from the Valkey Command Manual (that's the 3valkey manual, section 3, we love her) and she is here to tell you everything about LATENCY LATEST. it's giving observability. it's giving "why is my server slow" energy. let's go 💅

🌸 NAME 🌸

latency-latest — returns the latest latency samples for all events. that's it. that's the whole job. she's a reporter, not a fixer 💖

✨ SYNOPSIS ✨

LATENCY LATEST

that's it. no args. no options. she ate and left no crumbs 🎀

🦋 DESCRIPTION 🦋

so the LATENCY LATEST command reports the latest latency events that got logged. like, "hey bestie, here's what was slow recently" 💀

each reported event comes with these fields:

  • event name — who did it, basically. the name of the event.
  • unix timestamp of the latest latency spike for that event.
  • latest event latency, measured in milliseconds.
  • all-time maximum latency for this event.
  • sum of the latencies recorded in the time series for this event — this one was added in 8.1 ✨
  • number of latency spikes recorded in the time series for this event — also added in 8.1 ✨

now, "all-time" is doing a lot of work in that sentence, so let's be clear: it means the maximum latency since the Valkey instance was started, OR since the time that events were reset via LATENCY RESET — that's valkey-latency-reset(7) if you wanna look her up 🧚

not me casually resetting my trauma and calling it "all-time" 😭 anyway. facts are facts.

💜 REPLY 💜

per valkey-protocol(7), you get an Array reply: an array where each element is a four elements array representing the event's name, timestamp, latest and all-time latency measurements. iconic format. very demure, very mindful 🎀

🌈 COMPLEXITY 🌈

O(1)

constant time. she is fast. main character energy, zero effort, all vibes 👑
