Collected Metrics

List of collected metrics is described in METRICS.md.

Example

Example running ping collector and writing data to a file.

Make sure that your $SNAP_PATH is set, if not:

$ export SNAP_PATH=<snapDirectoryPath>/build

Other paths to files should be set according to your configuration, using a file you should indicate where it is located.

In one terminal window, open the snap daemon (in this case with logging set to 1, trust disabled and global configuration saved in config.json ):

$ $SNAP_PATH/bin/snapteld -l 1 -t 0 --config config.json

In another terminal window: Load ping plugin

$ $SNAP_PATH/bin/snaptel plugin load snap-plugin-collector-ping

See available metrics for your system

$ $SNAP_PATH/bin/snaptel metric list

Create a task manifest file (exemplary files in [examples/tasks/] (https://github.com/raintank/snap-plugin-collector-ping/blob/master/examples/tasks/)):

{
    "version": 1,
    "schedule": {
        "type": "simple",
        "interval": "1s"
    },
    "workflow": {
        "collect": {
            "metrics": {
                "/raintank/ping/*": {}
            },
            "config": {
            	"/raintank/ping": {
            		"hostname": "127.0.0.1"
            	}
            },
            "process": null,
            "publish": [
                {
                    "plugin_name": "file",
                    "config": {
                        "file": "/tmp/published_ping"
                    }
                }
            ]
        }
    }
}
