README

This program provides the ability to limit the notifications sent by icinga2 per recipient. A limit is defined as the maxmimum number of notifications in a specified time interval (e.g. 100 notifications per hour).

BUILD

Requirements

  • pybuilder

Build

pyb

INSTALLATION (example)

Program

cd  target/dist/icinga2_notification_limit-<VERSION>/dist
tar -xzf icinga2_notification_limit-<VERSION>.tar.gz
cd icinga2_notification_limit-<VERSION>
python setup.py install

Database

CREATE TABLE icinga_notification_limits (
    id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    maximum INT UNSIGNED NOT NULL,
    timerange INT UNSIGNED NOT NULL,
    PRIMARY KEY (id)
);


CREATE TABLE icinga_notification_counters (
    id INT UNSIGNED AUTO_INCREMENT,
    recipient VARCHAR(50) NOT NULL,
    limitId INT UNSIGNED NOT NULL,
    counter INT UNSIGNED DEFAULT 0,
    updated TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    PRIMARY KEY (id),
    FOREIGN KEY (limitId) REFERENCES icinga_notification_limits(id)
);

CONFIGURATION (example)

Database

  • The maxmimum field of the *_limits table represents the maximum number of notifications for the limit.
  • The timerange field of the *_limits table represents the time interval in seconds for the limit.
  • The recipient field of the *_counters table represents an identifier of the targeted recipient (e.g. email address for mail notification).
  • The limitId field of the *_counters table links the recipient to a limit. By now, only one limit per recipient is supported!
INSERT INTO icinga_notification_limits (maximum, timerange) VALUES (100, 60);

INSERT INTO icinga_notification_counters (recipient, limitId) VALUES ('jucker@gyselroth.com', 3);

USAGE

The program itself does not invoke any notification. Instead, the program returns a value of 0, if the notification should be send and a value of 1 if the notification should not be send. Therefore the program can be used in any script. Tip: Look at the shellscript examples for usage with the default mail-notification-scripts in examples folder.
