Crate mira 

Mira: OTLP in, immutable Arrow blocks out, one binary.

Modules

alert 🔒

Static-rule alerting: a KYAML document in, webhooks out.

api 🔒

The query API.

config 🔒

Deployment configuration: KYAML with OmegaConf-style interpolation.

json 🔒

OTLP/HTTP with a JSON body.

mcp 🔒

MCP, on the same port as everything else.

pipeline 🔒

The ingest path.

receiver 🔒

OTLP receivers.

telemetry 🔒

Mira storing Mira’s telemetry, in Mira.

term 🔒

A terminal, hand-rolled on libc.

tui 🔒

The terminal UI.

ui 🔒

The UI, compiled into the binary.

update 🔒

mira update — replace this binary with a release from GitHub.

Constants

DRAIN_GRACE 🔒

How long a stop is allowed to take before the process leaves without it.

USAGE 🔒

Statics

QUERIES 🔒

Queries served and what they cost, since start.

QUERY_MAX_NANOS 🔒

QUERY_NANOS 🔒

START 🔒

When the process started, so the counters below have a denominator. Forced in serve_with rather than left to first touch, or “uptime” would mean “seconds since someone first asked”.

Functions

check_source 🔒

The guards serve_with runs, for a mira mira --data-dir that maps exactly the same blocks with no server in front of it.

drain 🔒

Stop accepting, then let everything already in flight land.

first_stopped 🔒

Resolve as soon as any one flusher has returned.

health 🔒

Liveness, plus what the ingest path has refused so far.

json_ok 🔒

load 🔒

Precedence is flag > file > default. Hand-rolled: the flag set exists only to override the file, so a parser crate would be more code than the thing it parses.

load_from 🔒

load without the two flags that end the process, so it can be called.

main 🔒

ops_router 🔒

The three endpoints that answer for the process rather than for the data: liveness, readiness, and everything this node counts about itself.

peak_rss 🔒

High-water mark of this process’s resident set, in bytes.

ready 🔒

Readiness is one question: can this instance accept an export and make it durable? Everything else about the process is /health’s.

readyz 🔒

Readiness: 200 while exports can be made durable, 503 once they cannot.

replay 🔒

Push everything the log holds that no block claims back through the flushers, before the listeners open.

run 🔒

serve 🔒

serve_with 🔒

The server proper, with its stop edge passed in rather than taken from the process. A test can hold that edge; nothing else needs to.

shutdown 🔒

Resolve on the first stop signal.

stats 🔒

Everything this node knows about itself, in one document.

timed 🔒

Wrapped around the query router only, so OTLP writes and UI asset fetches do not land in the read latency an operator is reading.

tui_source 🔒

Where a mira mira invocation should read from.
