irasnyd/cacti repository overview

⁠Introduction

Dockerized version of Cacti⁠, the complete rrdtool-based graphing solution.

The web interface is available at two different URLs simultaneously, to allow for the easiest migration path for both new and old users. You can access it both at the / and /cacti/ URLs.

⁠Environment Variables

You can customize the behavior of this container using these variables. They all correspond directly to variables in the /etc/cacti/db.php configuration file.

• DB_TYPE - Set the database type (default: mysql)
• DB_NAME - Database name (default: cacti)
• DB_HOST - Database host (default: localhost)
• DB_USER - Database username (default: cactiuser)
• DB_PASS - Database password (default: cactiuser)
• DB_PORT - Database port (default: 3306)
• DB_SSL - Use SSL to connect to database (default: false)
• CACTI_SESSION_NAME - Cacti session name (default: Cacti)

⁠Database

Cacti requires the following database permissions (grants):

GRANT ALL PRIVILEGES ON cacti.* TO cacti@'%' IDENTIFIED BY 'cacti';
GRANT SELECT ON mysql.time_zone_name TO cacti@'%';

The Cacti source code has been patched to disable persistent connections. This change helps Cacti avoid opening too many concurrent connections to the database, swamping other user's ability to connect.

⁠Example
