Hatohol consolidates monitoring data from any number of running monitoring systems on one screen. This feature enables the integration of monitoring centers, even when these centers are in different places or are being monitored by different software.


Hatohol currently maintains the following information:

  • Items

    Monitoring items of targets, such as CPU load and free memory size.

  • Triggers

    The current status of monitoring items.

  • Events

    History of items' status changes. When an event detected, Hatohol can execute a defined user command (called an action).

Basic architecture

Hatohol consists of a server and a Web front-end. Hatohol server gathers monitoring information from monitoring servers such as Zabbix, Nagios, Ceilometer, and Fluentd. It then integrates gathered data and stores in the DB. The other programs can get the integrated data via Hatohol's REST API. A Hatohol Web front-end internally communicates with the server and creates a response page to see the consolidated data.


The architecture used, makes it easy to develop alternative clients. There is no internal complication in adding Android applications, iOS applications, Win32 native clients or Web applications with other frameworks.


  • Dashboard dashboard

  • Events events

  • Servers servers

Other pages are being constructed.
