Cacti is an open source, web-based frontend to RRDtool, the industry standard, high performance data logging and graphing system for time series data.
Cacti stores all of the necessary information to create graphs and populates them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain graphs, data sources, and round robin archives in a database, Cacti handles the data gathering.
There is also SNMP support for those used to creating traffic graphs with MRTG.
Key Features
- Unlimited number of graph items can be defined for each graph optionally utilizing CDEFs or data sources from within Cacti.
- Automatic grouping of GPRINT graph items to AREA, STACK, and LINE[1-3] to allow for quick re-sequencing of graph items.
- Graph data can be manipulated using the CDEF math functions built into RRDTool. These CDEF functions can be defined in cacti and can be used globally on each graph.
- Support for all of RRDTool’s graph item types including AREA, STACK, LINE[1-3], GPRINT, COMMENT, VRULE, and HRULE.
- Data sources can be created that utilize RRDTool’s “create” and “update” functions.
- Supports RRD files with more than one data source.
- Customization of Round robin archive (RRA) settings.
- Define custom scripts that can be used to gather data.
- Built in SNMP support that can use php-snmp, ucd-snmp, or net-snmp.
- Ability to retrieve data using SNMP or a script with an index.
- PHP-based poller is provided to execute scripts, retrieve SNMP data, and update your RRD files.
- Auto-Padding support to make sure graph legend text lines up.
- 95th percentile.
- User based management allows administrators to create users and assign different levels of permissions to the cacti interface.
