kiwi-simple-metrics

kiwi - simple, consistent, powerful

A lightweight monitoring solution for kiwi-scp, created with uptime-kuma in mind. Also on Docker Hub.

Quick start

The minimal config to add to one of your docker-compose.yml is this:

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:

metrics:
  image: yavook/kiwi-simple-metrics:0.1
  environment:
    METRICS__LOG__ENABLED: "True"
    METRICS__WEBHOOK__URL: "https://my.webhook.host/success?report={result}"
    METRICS__WEBHOOK__FAIL: "https://my.webhook.host/failure?report={result}"

• same metrics as above
• logs reports to stdout
• triggers webhooks ({result} 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 (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. 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.
