Usage

Checking Metrics

The following example checks that the count of running processes is between 150 and 300

• a warning message will be triggered if the count is below 150 or above 300
• a critical message will be triggered if the count is below 100 or above 350

check-dcos-metrics.rb -u 'http://127.0.0.1:61001/system/v1/metrics/v0/node' -m 'process.count' -w 150 -c 100 -W 300 -C 350

In some cases the metric name is not unique but you can filter metrics by tags using the --filter option followed by TAG_NAME:TAG_VALUE You can also check deltas, if you pass the -d option the plugin will keep the previous value in a daybreak db and compare the new value against it.

check-dcos-metrics.rb -m 'network.in.errors' -d -f interface:docker0 -C 2 -W 1

Run check-dcos-me.rb -h for all the options.

Check configuration example:

This is an example how to use this plugin to ship metrics to InfluxDB using the sensu-extensions-influxdb extension:

{
  "checks": {
    "dcos-host-metrics": {
      "type": "metric",
      "command": "/opt/sensu/embedded/bin/metrics-dcos-host.rb",
      "influxdb": {
        "templates": {
          "dcos\\..*\\.filesystem\\.": "source.type.measurement.field2.nil.nil.path*",
          "dcos\\..*\\.network\\.": "source.type.measurement.field2.nil.nil.interface*",
          "dcos\\.": "source.type.measurement.field*"
        },
        "tags": {
          "group": "node"
        }
      }
  }
}

Host Health Check

The check-dcos-ping.rb will return OK if the host reports itself as heathy or CRITICAL otherwize

check-dcos-ping.rb -h 'http://127.0.0.1:61001/system/v1/metrics/v0/ping'
