Sensu System Profile Extension

This check extension collects Linux system metrics. This extension reads and parses /proc/stat, /proc/loadavg, /proc/net/dev, and /proc/meminfo to produce Linux system metrics in the Graphite plaintext format. Sensu can send the collected metrics to Graphite or another TSDB such as InfluxDB.

Installation

This extension requires Sensu version >= 0.26.

On a Sensu client machine.

sensu-install -e system-profile:1.0.0

Edit /etc/sensu/conf.d/extensions.json to load it.

{
  "extensions": {
    "system-profile": {
      "version": "1.0.0"
    }
  }
}

Restart the Sensu client.

sudo service sensu-client restart

Configuration

Edit /etc/sensu/conf.d/system_profile.json to change its configuration.

{
  "system_profile": {
    "interval": 30
  }
}

attribute	type	default	description
interval	integer	10	How often metrics will be collected and sent to Sensu
add_client_prefix	boolean	true	If the Sensu client name should prefix the Graphite metric path
path_prefix	string	"system"	The Graphite metric path prefix
prefix_at_start	boolean	true	If the path_prefix should be before the Sensu client name
handler	string	"graphite"	Handler to use for the Graphite metrics
