The Opendelight IDE (Integrated Development Environment) is a web-based tool to develop and manage your application with the Opendelight. This tool is included along with the Opendelight download on its Download page.
The Opendelight IDE can be accessed at the URL,
<application_base_url>/ide; and it provides utilities to:
- View recently edited events and controllers apart from blog posts about the Opendelight on the Batoi website and links to the Opendelight documentation (in fact, each screen on the Opendelight IDE provides a link to documentation contextually)
- Manage Controllers and Events with each
- Manage Model (Application Classes, Script Includes, and Configuration Variables)
- Manage Users and their Roles
- Manage Lifestream
- View and edit Application Settings
- Change Admin Password
Application Settings refer to setup information that is used while installing the Opendelight, thus setting up the application with the Opendelight. This includes the application name, description, author name, email address of the admin user, URL of the application, and database settings. Database settings include DSN, Database Name, DB user and Password, and Table Prefix (the string that will be prepended to each table of the application including the Opendelight Database Tables).
You can edit the application settings on the Opendelight IDE. But you need to be careful about the Application Base URL as it may make the application dysfunctional. However, you can manage your Lifestream log (enabling and disabling) here apart from other aspects of the application. There is no facility to edit database settings for an application as there is a separate utility (currently under development) to help you migrate your application to different databases and different locations.
The Opendelight has an inbuilt capability to track access to the application created through it. This is enabled by default during the installation of the Opendelight. You can see the access log of the application in the section meant for Lifestream on the Opendelight IDE.
Each day log is stored in separate text files and creates a new row on the Lifestream page on the Opendelight IDE. The log files are stored in the directory
/log, and rows of log file look like the following (two lines of a successfully executed event have been presented for illustration):
25 March 2010, 7:10 am - Application accessed by user admin through URL /appl/index.php?ID=6 from IP 127.0.0.1. 25 March 2010, 7:10 am - Application executed in 0.1765148639679 sec.
The first line above describes the access by the user (if it is public access, no user information will be present), and the second line describes the successful execution of the event. In case of failure in the execution of an event, the second line will be absent in the log. As the log stores critical information like user, URL, IP from which access is done, and time for execution of the event, it is very useful to study the performance of the application.
The IDE has the utility to delete the log of any particular day, and also to remove the entire history of the access log.
NOTE: You may like to disable the Lifestream log (this can be done by editing the Application Settings) as it produces daily log files and thus consumes disk space. But it is advisable to keep it enabled and to remove the history periodically. The removal of history is extremely critical on high-traffic sites or applications.
