Loggin IPMI Data to Sensu and InfluxDB

Accessing the Cisco servers is explained here in detail.

IPMItool Installation

You can access IPMI functionality through the command line with the IPMItool utility. To be able to use ipmitool, install it with the following

$ yum install OpenIPMI OpenIPMI-tools
$ chkconfig ipmi on
$ service ipmi start

You can also locate IMPItool and its related documentation on your Tools and Drivers CD image, or download this tool

After you install the IPMItool package, you can access detailed information about command usage and syntax from the man page that is installed. From a command line, type man ipmitool

Connecting to the Server With IPMItool

To connect over a remote interface you must supply a user name and password. The default user with admin-level access is root with password changeme.

On the NE cluster, the username and password credentials for the Cisco server OBMs are provided in the command ipmitool -I lanplus -H -U admin -P 73qtx8nVXa4c06 chassis status

Using IPMItool to Read Sensors

To get a list of all sensors in these servers and their status, use the sdr list command with no arguments. This returns a large table with every sensor in the system and its status.

The four fields of the output lines, as read from left to right are:

  1. IPMI sensor number
  2. IPMI sensor ID
  3. Sensor reading
  4. Sensor status, indicating which thresholds have been exceeded.

For example:

2 | /SYS/SLOTID | 0x02 | ok

3 | HOSTPOWER   | 0x02 | ok

4 | CMM/PRSNT   | 0x02 | ok

5 | PEM/PRSNT   | 0x02 | ok

This doc provides additional information including reading specific sensors.

Logging sensor readings into Sensu

After parsing the sensor data into “<host.sensor-name> ” format using this script, a sensu check picks up the output and logs it into the sensu server.

      "handlers": ["default","influxdb"],
      "type": "metric",
      "command": "/etc/sensu/plugins/check-sensor-t.rb -u admin -p 73qtx8nVXa4c6 -h",
      "interval": 30,
      "subscribers": [ "moc-sensu" ]

The influxdb handler stores the sensor data in inflxdb.
