how to set sensu check defaults and override them per client as needed instead of defining whole check on client side , so ultimately this way the only checks than need to be defined on client side are standalone checks

client side

/etc/sensu/conf.d/checks/thresholds/logstash-elasticsearch.json

{
  "client": {
    "params": {
      "cpu": {
        "warning": 80,
        "critical": 90
      },
      "iowait": {
        "warning": 50,
        "critical": 70
      }
    }
  }
}

server side

/etc/sensu/conf.d/checks/cpu.json

{
  "checks": {
    "check_cpu": {
      "command": "/etc/sensu/plugins/check-cpu.rb -w :::params.cpu.warning|70::: -c :::params.cpu.critical|90::: --sleep 30",
      "interval": 60,
      "occurrences": 3,
      "subscribers": [ "common" ],
      "handlers": [ "default" ]
    }
  }
}

/etc/sensu/conf.d/checks/iowait.json

{
  "checks": {
    "check_iowait": {
      "command": "/etc/sensu/plugins/check-cpu.rb -w :::params.iowait.warning|30::: -c :::params.iowait.warning|50::: --iowait --sleep 30",
      "interval": 60,
      "occurrences": 3,
      "subscribers": [ "logstash-elasticsearch", "graphite", "mysql" ],
      "handlers": [ "default" ]
    }
  }
}
