goprecords - Global uptime records

goprecords is a Go command-line program that generates uptime reports for hosts based on the input record files from uptimed. It supports importing records into SQLite and querying for reports, reporting directly from a stats directory, or (optionally) running as an HTTP server that exposes the same reports and authenticated uploads.

Features

• Supports multiple categories: Host, Kernel, KernelMajor, and KernelName
• Supports multiple metrics: Boots, Uptime, Score, Downtime, and Lifespan
• Output formats available: Plaintext, Markdown, Gemtext, and HTML
• Provides top entries based on the specified limit

Whereas:

• Boots: Total count of system boots.
• Uptime: Total hosts uptimes.
• Score: A meta score, calculated combining all other metrics.
• Downtime: Total hosts downtimes.
• Lifespan: Downtimes plus uptimes.

Usage

• -version — Print version and exit.
• import — Import .records files into a SQLite database (repeatable: replaces existing data).
  • -stats-dir (required): Directory containing *.records files.
  • -db: Database path (default: goprecords.db).
• query — Generate reports from an existing SQLite database.
  • -db: Database path (default: goprecords.db).
  • -category, -metric, -limit, -output-format, -all, -include-kernel, -stats-order (same as below).
• No subcommand — Generate reports directly from a stats directory (no DB).
  • -stats-dir (required): The uptimed raw record input dir.
  • -category: One of Host, Kernel, KernelMajor, KernelName (default: Host).
  • -metric: One of Boots, Uptime, Score, Downtime, Lifespan (default: Uptime).
  • -limit: Max entries (default: 20).
  • -output-format: Plaintext, Markdown, Gemtext, or HTML (default: Plaintext).
  • -all: Generate all reports except Kernel.
  • -include-kernel: Include Kernel when using -all.
  • -stats-order: Comma-separated Category:Metric order for -all.

Example usage

# Build (or use mage)
go build -o goprecords ./cmd/goprecords

# Import then query (repeatable)
./goprecords import -stats-dir=~/git/uprecords/stats -db=goprecords.db
./goprecords query -db=goprecords.db -category=Host -metric=Uptime -limit=10 -output-format=Markdown

# Or report directly from files
./goprecords -stats-dir=~/git/uprecords/stats -all -stats-order="Host:Uptime,Host:Boots"

Daemon mode (HTTP API, plain HTTP)

Backward compatibility: import, query, and no-subcommand reporting from -stats-dir behave as before. The HTTP server is additional; CLI-only workflows are still supported with no intentional behavior removal.

goprecords serves plain HTTP only (Go net/http without TLS). Terminate TLS externally—Kubernetes Ingress, a reverse proxy (nginx, Caddy, …), or a load balancer—when clients require HTTPS.

goprecords --daemon -stats-dir="$HOME/git/uprecords/stats" -listen=":8080"

(-daemon and --daemon are equivalent.)

Stats directory vs databases

• Stats tree — -stats-dir (required) or GOPRECORDS_STATS_DIR: uptimed files (HOST.txt, HOST.records, …). The daemon builds GET /report responses from this directory only; it does not read the import / query SQLite file (-db, default goprecords.db).
• Listen address — -listen or GOPRECORDS_LISTEN (default :8080).
• Upload auth database — -auth-db: SQLite file holding per-client API key hashes (default <stats-dir>/goprecords-auth.db). This is separate from the aggregates DB used by import / query.

Endpoints

• GET /health and GET /livez — Liveness (200, body ok).
• GET /readyz — Readiness: checks the stats directory is readable/writable (and the auth DB parent directory when auth-db is outside the stats tree). Returns 503 if not ready.
• GET /report — Same report options as query and no-subcommand mode (aggregated from the stats directory). Only GET is supported (other methods → 405). Query parameters use the same names and defaults as the CLI flags; you can also use the aliases Category, Metric, and OutputFormat:
  • category, metric, limit (default 20)
  • output-format / OutputFormat: Plaintext, Markdown, Gemtext, or HTML (default Plaintext); the response Content-Type matches (e.g. text/html for HTML)
  • all, include-kernel: booleans (true / false, 1 / 0, yes / no)
  • stats-order: comma-separated Category:Metric list when all is true
• PUT /upload/{HOSTNAME}/{kind} — Writes one file under the stats directory; 204 on success. The HOSTNAME path segment must match the hostname the client key was issued for when auth is enforced.

HTTP API reference with curl

• GET /health
  • Purpose: basic liveness probe.
  • Success: 200 OK, body ok.
  • Example:

curl -i "http://127.0.0.1:8080/health"

• GET /livez
  • Purpose: Kubernetes-style liveness probe (same semantics as /health).
  • Success: 200 OK, body ok.
  • Example:

curl -i "http://127.0.0.1:8080/livez"

• GET /readyz
  • Purpose: readiness probe (verifies required directories are readable and writable).
  • Success: 200 OK, body ok.
  • Not ready: 503 Service Unavailable.
  • Example:

curl -i "http://127.0.0.1:8080/readyz"

• GET /report
  • Purpose: generate reports from the daemon stats directory.
  • Method: only GET (405 for other methods).
  • Main query parameters:
    • category: Host, Kernel, KernelMajor, KernelName
    • metric: Boots, Uptime, Score, Downtime, Lifespan
    • output-format: Plaintext, Markdown, Gemtext, HTML
    • limit: integer (default 20)
    • all, include-kernel: booleans
    • stats-order: comma-separated Category:Metric
    • aliases: Category, Metric, OutputFormat
  • Content types:
    • Plaintext/Markdown: text/plain; charset=utf-8
    • Gemtext: text/gemini; charset=utf-8
    • HTML: text/html; charset=utf-8
  • Examples:

curl -fsS "http://127.0.0.1:8080/report?category=Host&metric=Uptime&limit=10&output-format=Plaintext"
curl -fsS "http://127.0.0.1:8080/report?category=Kernel&metric=Boots&output-format=Gemtext"
curl -fsS "http://127.0.0.1:8080/report?Category=Host&Metric=Score&OutputFormat=HTML&limit=5"
curl -fsS "http://127.0.0.1:8080/report?all=true&include-kernel=true&output-format=Markdown"

• PUT /upload/{HOSTNAME}/{kind}
  • Purpose: upload host files into the daemon stats directory.
  • Method: only PUT (405 for other methods).
  • Success: 204 No Content.
  • Auth behavior:
    • If no keys exist in auth DB: upload is accepted without Authorization.
    • If one or more keys exist: requires Authorization: Bearer <token>.
    • Missing/invalid header: 401 Unauthorized (with WWW-Authenticate: Bearer ...).
    • Wrong host/token pair: 403 Forbidden.
  • Examples:

# without auth (works only when no client keys exist in auth DB)
curl -i -X PUT --data-binary @./myhost.records \
  "http://127.0.0.1:8080/upload/myhost/records"

# with auth (required when keys exist)
TOKEN="..."  # from --create-client-key
curl -i -X PUT --data-binary @./myhost.records \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/records"

• Create upload client key (CLI companion flow)
  • This is not an HTTP API endpoint. Key creation is intentionally CLI-only.
  • Command examples:

goprecords --create-client-key myhost -stats-dir="$HOME/git/uprecords/stats"
goprecords --create-client-key otherbox -auth-db=/var/lib/goprecords/goprecords-auth.db

GET /report examples

curl -fsS "http://127.0.0.1:8080/report?category=Host&metric=Uptime&limit=10&output-format=Markdown"
curl -fsS "http://127.0.0.1:8080/report?OutputFormat=HTML&limit=5"

For kind in the upload URL, the server creates or overwrites this file in the stats directory:

kind in URL	File created
txt	HOSTNAME.txt
cur.txt	HOSTNAME.cur.txt
records	HOSTNAME.records
os.txt	HOSTNAME.os.txt
cpuinfo.txt	HOSTNAME.cpuinfo.txt

Per-client keys — When the auth database has at least one key, each upload must send Authorization: Bearer <token> where <token> is the secret printed once by goprecords --create-client-key HOSTNAME (or -create-client-key). The token is validated for that HOSTNAME only (same string as in the upload path). You need -stats-dir (to derive the default auth DB path) or -auth-db:

goprecords --create-client-key myhost -stats-dir="$HOME/git/uprecords/stats"
goprecords --create-client-key otherbox -auth-db=/var/lib/goprecords/goprecords-auth.db

Creating a key for a hostname that already has one replaces the previous secret.

Example curl uploads with the Authorization header:

TOKEN="…"   # output of --create-client-key

curl -fsS -X PUT --data-binary @./myhost.records \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/records"

curl -fsS -X PUT --data-binary @./myhost.txt \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/txt"

curl -fsS -X PUT --data-binary @./myhost.cur.txt \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/cur.txt"

curl -fsS -X PUT --data-binary @./myhost.os.txt \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/os.txt"

curl -fsS -X PUT --data-binary @./myhost.cpuinfo.txt \
  -H "Authorization: Bearer $TOKEN" \
  "http://127.0.0.1:8080/upload/myhost/cpuinfo.txt"

Setting up a new upload client

Use the same HOSTNAME everywhere: the argument to --create-client-key, each PUT /upload/HOSTNAME/{kind} URL, and (by convention) the basename of your uptimed files under the stats directory. Pick a stable short name (for example the first label of hostname -f).

1. Issue a token on the server (where the daemon’s stats tree and auth DB live). The plaintext token is printed once; store it only on the client.

# Daemon on this host; auth DB defaults to <stats-dir>/goprecords-auth.db
goprecords --create-client-key myhost -stats-dir=/var/lib/goprecords/stats

# Or pass auth DB explicitly
goprecords --create-client-key myhost -auth-db=/var/lib/goprecords/goprecords-auth.db

If goprecords runs in Kubernetes, run the same subcommand in the pod (adjust namespace and stats mount if needed):

kubectl exec -n services deployment/goprecords -- \
  goprecords --create-client-key myhost -stats-dir=/data/stats

Re-running --create-client-key for the same hostname replaces the previous token; update the client immediately after rotation.

2. On the client, keep the token in a root-owned or user-private file (for example mode 600) and use curl with Authorization: Bearer as in the examples above. Set the base URL to your daemon (plain HTTP behind the pod or https:// behind ingress).

3. Source files — Typical uptimed locations: /var/spool/uptimed/records (many Linux distributions and FreeBSD pkg installs), /usr/local/var/uptimed/records (macOS/Homebrew), /var/db/uptimed/records (some other BSD layouts). The upload client checks those paths in that order. Use uprecords from the uptimed package to regenerate txt and cur.txt-equivalent content when you upload those kinds. os.txt and cpuinfo.txt are often /etc/os-release and /proc/cpuinfo on Linux.

4. Automate (optional) — A oneshot systemd service can call a small script that **PUT**s each present file; a systemd.timer (for example OnCalendar=hourly) triggers it. For a user timer, enable lingering if uploads should run while no graphical session is active:

sudo loginctl enable-linger "$USER"

If there are no keys in the auth database, uploads are accepted without Authorization (useful for local testing only).

Excluding hosts from /metrics alerts

Hosts that no longer send updates can be marked as excluded so Prometheus alert rules can filter them out. Excluded hosts still appear in /metrics with excluded="true".

Exclude a host

# daemon on Kubernetes — auth DB lives on the stats PVC
kubectl exec -n services deployment/goprecords -- \
  goprecords exclude -db=/data/stats/goprecords-auth.db -reason="decommissioned" myhost

# local daemon
goprecords exclude -db=/var/lib/goprecords/goprecords-auth.db -reason="decommissioned" myhost

List excluded hosts

kubectl exec -n services deployment/goprecords -- \
  goprecords list-excluded -db=/data/stats/goprecords-auth.db

Remove an exclusion manually

kubectl exec -n services deployment/goprecords -- \
  goprecords unexclude -db=/data/stats/goprecords-auth.db myhost

Auto-unexclude

When a host resumes sending uploads its records file mtime becomes newer than excluded_at. On the next /metrics scrape the daemon detects this and automatically removes the exclusion — no manual intervention needed.

Manual upload client (all operating systems)

The unified script scripts/goprecords-upload-client.sh works on FreeBSD, Linux, and OpenBSD as root or a regular user. A copy is also kept in contrib/ for backward compatibility.

Full per-OS installation instructions (token setup, cron/systemd automation, test runs) are in docs/upload-client.md.

Test

Run the test subcommand (fixture comparison and import/query parity):

./goprecords test

Or run Go unit tests:

go test ./...
# or: mage test

End-to-end usage

Use uptimed to produce uptime statistics

First, you need to generate uptime statistics from all hosts by installing and running uptimed. There's a package available for most common Linux and *BSD distributions nowadays. It's also available for macOS (Darwin) via Homebrew. For example, under Fedora, run sudo dnf install uptimed. https://github.com/rpodgorny/uptimed

Collect all uptime records to a central location

Second, you must collect the records files produced by uptimed. Which are the raw uptime statistic files continuously updated by uptimed. Depending on the operating system used, the location of the records file can vary. It is advisable to store all the record files in a central git repository.

An example records file looks like this:

11175544:1658053426:OpenBSD 7.1
10033984:1669229566:OpenBSD 7.2
7701011:1642849465:OpenBSD 7.0
3900089:1650550947:OpenBSD 7.1
3573912:1654452258:OpenBSD 7.1
2132201:1640713822:OpenBSD 7.0
88762:1640625045:OpenBSD 7.0
18452:1640603646:OpenBSD 7.0
3408:1642846040:OpenBSD 7.0
2315:1640622113:OpenBSD 7.0
1190:1654451052:OpenBSD 7.1
334:1650550601:OpenBSD 7.1
310:1669229245:OpenBSD 7.2
310:1640624443:OpenBSD 7.0
261:1640624769:OpenBSD 7.0
144:1669229090:OpenBSD 7.2

... whereas the first number is the total uptime since boot, and the second is the boot time. The last column identifies the operating system and kernel version.

guprecords does not provide any out-of-the-box solution for the collection part. I use a quick-and-dirty Makefile in a uptimes.git repository, where I can run make push to manually collect and push the uptime statistics of the current host to the git repository. I log in to all my machines anyway, sooner or later, and I also automatically run a shell script (via my login RC file) to re-collect the stats when they weren't collected for a week or so. So this solution is "just good enough" for me for now:

manual:
    records_path=/var/spool/uptimed/records; \
    test -f /usr/local/var/uptimed/records && records_path=/usr/local/var/uptimed/records; \
    test -f /var/db/uptimed/records && records_path=/var/db/uptimed/records; \
    cp $$records_path ./stats/$$(hostname | cut -d. -f1).records
    uprecords -a -m 100 > ./stats/$$(hostname | cut -d. -f1).txt
    uprecords -a | grep '^->' > ./stats/$$(hostname | cut -d. -f1).cur.txt
    git add ./stats/*
    git commit -a -m 'new uptime
push: manual
    git add ./stats/$(hostname)*
    git commit -a -m 'new stats'
    git pull origin master
    git push origin master

Generate global uptime stats

Third, import and query (or report from files):

./goprecords import -stats-dir=$HOME/git/uprecords/stats -db=goprecords.db
./goprecords query -db=goprecords.db -all

Or without a database:

./goprecords -stats-dir=$HOME/git/uprecords/stats -all

Host names have a one-character status marker: * means the latest uptime record is within 90 days; + means the host uploaded within the last 24 hours, but its latest completed uptime record is stale or has not yet been written. The latter commonly occurs during the first hour after boot when uptimed uses LOG_MINIMUM_UPTIME=1h.

... to generate something like the following:
