NSCA Client

This is a technical module to send passive alerts to your favorite NSCA daemon (Nagios, Shinken...). This module is based on the Odoo cron system and requires a NSCA client installed on the system to satisfy the /usr/sbin/send_nsca command.

Installation

To use this module, you need to install a NSCA client.

On Debian/Ubuntu:

$ sudo apt-get install nsca-client

Configuration

To configure this module, you need to:

  • Configure your server and a passive service in your monitoring tool (e.g service Odoo Mail Queue on host MY-SERVER).
  • Declare your NSCA server in the menu Configuration / Technical / NSCA Client / Servers
nsca_client/static/description/server.png
  • Create NSCA checks in the menu Configuration / Technical / NSCA Client / Checks
nsca_client/static/description/check.png
  • Code the methods which will be called by the NSCA checks.

Such methods must return a tuple (RC, MESSAGE, PERFORMANCE_DATA) where RC is an integer, MESSAGE a unicode string AND PERFOMANCE_DATA is a dictionary. RC values and the corresponding status are:

  • 0: OK
  • 1: WARNING
  • 2: CRITICAL
  • 3: UNKNOWN

PERFORMANCE_DATA is not mandatory, so it could be possible to send (RC, MESSAGE). Each element of PERFORMANCE_DATA will be a dictionary that could contain:

  • value: value of the data (required)
  • max: Max value on the chart
  • min: Minimum value on the chart
  • warn: Warning value on the chart
  • crit: Critical value on the chart
  • uom: Unit of Measure on the chart (s - Seconds, % - Percentage, B - Bytes, c - Continuous)

The key of the dictionary will be used as the performance_data label.

E.g:

class MailMail(models.Model):
    _inherit = 'mail.mail'

    @api.model
    def nsca_check_mails(self):
        mails = self.search([('state', '=', 'exception')])
        if mails:
            return (1, u"%s mails not sent" % len(mails), {
              'exceptions': {'value': len(mails)}})
        return (0, u"OK", {'exceptions': {'value': len(mails)}})

On the example, the performance data will use the label exceptions and the value will be the number of exception of mails.
