What precautions should be taken when using the Cacti tool?
When using the Cacti tool, it is important to keep in mind the following points:
- Confirming system requirements: The Cacti tool needs to run on systems that support PHP and MySQL, so it is important to ensure that the system meets these requirements before installation.
- Installation and configuration of the database: Cacti requires MySQL database to store data, so it is necessary to install and configure MySQL database beforehand and create a database specifically for Cacti.
- Install SNMP: Cacti relies on SNMP protocol to obtain data from network devices, so make sure SNMP is installed on the system and enabled on the target device.
- Installation and configuration of a web server: Cacti is a web-based tool, therefore it requires the installation and configuration of a web server (such as Apache) to run Cacti.

- Set up devices: Add and configure devices to be monitored in Cacti. This includes entering the device’s IP address and SNMP community string, and selecting the parameters to be monitored.
- Adjust polling interval: By default Cacti polls devices every 5 minutes, but the polling interval can be adjusted according to actual needs to balance monitoring accuracy and system resource consumption.
- Chart monitoring management: Over time, the charts generated by Cacti may become excessive, requiring regular deletion of unnecessary charts to reduce database and storage space usage.
- Regular backup and maintenance: Consistently back up the Cacti database and configuration files to prevent unexpected data loss, as well as perform system maintenance and upgrades to ensure system security and stability.
- Learning and mastering the features of Cacti: Cacti is a powerful monitoring tool that requires learning and mastering its various functions and characteristics in order to fully utilize its monitoring capabilities.
