+[![Build Status](https://github.drone.yavook.de/api/badges/yavook/kiwi-simple-metrics/status.svg)](https://github.drone.yavook.de/yavook/kiwi-simple-metrics)
+
+> `kiwi` - simple, consistent, powerful
+
+A lightweight monitoring solution for [`kiwi-scp`](https://github.com/yavook/kiwi-scp), created with [`uptime-kuma`](https://github.com/louislam/uptime-kuma) in mind. Also [on Docker Hub](https://hub.docker.com/r/yavook/kiwi-simple-metrics).
+
+## Quick start
+
+The minimal config to add to one of your `docker-compose.yml` is this:
+
+```yaml
+metrics:
+  image: yavook/kiwi-simple-metrics:0.1
+```
+
+- admittedly not useful, but it *does* run monitoring
+- every 600 seconds (10 minutes), metrics are evaluated
+- measures cpu, memory and swap, and disk usage at "/"
+- does not log to stdout
+- does not trigger any webhooks
+
+Every aspect of kiwi-simple-metrics can be tweaked by environment variables, so this is a more reasonable configuration example:
+
+```yaml
+metrics:
+  image: yavook/kiwi-simple-metrics:0.1
+  environment:
+    METRICS__LOG__ENABLED: "True"
+    METRICS__WEBHOOK__URL: "https://my.webhook.host/success?report={}"
+    METRICS__WEBHOOK__FAIL: "https://my.webhook.host/failure?report={}"
+```
+
+- same metrics as above
+- logs reports to stdout
+- triggers webhooks (`{}` is the placeholder for the result string)
+
+## Configuration
+
+These are the environment variables you most likely need:
+
+- `METRICS__INTERVAL`: Time in seconds between metrics evaluation (default: `600`, i.e. 10 minutes)
+- `METRICS__LOG__ENABLED`: If truthy, logs reports to stdout (default: `False`)
+- `METRICS__[M]__ENABLED`, `METRICS__[M]__THRESHOLD` (with `[M]` from `CPU`, `MEMORY`, `DISK`): Enable or disable each metric, and set its failure threshold
+- `METRICS__MEMORY__SWAP`: How swap space is handled in the "memory" report (default: `include`)
+- `METRICS__DISK__PATHS`: At which paths the disk usage is measured (default: `["/"]`)
+- `METRICS__EXTERNAL__ENABLED`, `METRICS__EXTERNAL__EXECUTABLES`: Setup for `external values`, as further defined in [`metrics/external.py`](./tree/master/kiwi_simple_metrics/metrics/external.py) (default: `False`, `[]`)
+- `METRICS__WEBHOOK__URL`, `METRICS__WEBHOOK__FAIL`: Which webhooks to push the reports to (default: `None`, `None`)
+
+All settings can be found in the `SETTINGS` variable defined by module [`kiwi_simple_metrics.settings` in `settings/__init__.py`](./tree/master/kiwi_simple_metrics/settings/__init__.py). For default values, refer to the respective python files.
+
+Example: The above `METRICS__LOG__ENABLED` refers to `SETTINGS.log.enabled`, defined by model [`LogSettings` in `settings/misc.py`](./tree/master/kiwi_simple_metrics/settings/misc.py).
