Abakus Status Checks

This package is used together with Sensu. Checks is managed with Puppet and reported to our #devops channel on Slack.

Supported checks:

• CPU percent
• Load

Create a new check

• Create a new file in the abakus_checks/checks directory
• Import abakus_checks.utils.check.StatusCheck and use this as a base for your check.
• Give the check a name, decription and options

name = 'load'
description = 'Trigger errors based on load threshold. Load is divided by core count.'
options = [
    click.option('--warning', default='2,1.5,1', type=str),
    click.option('--critical', default='3,2,1.5', type=str),
]

• Implement the run method. Call self.ok, self.warning, self.critical with a message based on the

result.

• Register the check in abakus_checks/cli.py. Import the check in the check import block and

register the check.

from .checks import load
register_check(load.LoadCheck)

• You can use the tests.test_case.CLITestCase to test the check. This TestCase has a .invoke

method you can use to call the check.

class LoadCheckTestCase(CLITestCase):

    @mock.patch('os.getloadavg', return_value=(0, 0, 0))
    def test_load_ok(self, mock_loadavg):
        result = self.invoke(['load', '--warning /'3.2.1/''])
        self.assertEquals(result.exit_code, 0)
