# 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

```bash
# 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.

```bash
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.

**`GET /report` examples**

```bash
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`**:

```bash
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:

```bash
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"
```

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

## Test

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

```bash
./goprecords test
```

Or run Go unit tests:

```bash
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
```

... to generate something like the following:
