Features
Graphs
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.
Auto-Padding support to make sure graph legend text lines up.
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
Data sources can be created that utilize RRDTool's "create" and
"update" functions. Each data source can be used to gather local or remote
data and placed on a graph.
Supports RRD files with more than one data source and can use an RRD file
stored anywhere on the local file system.
Round robin archive (RRA) settings can be customized giving the user
the ability to gather data on non-standard timespans while store varying amounts
of data.
Data Gathering
Contains a "data input" mechanism which allows users to define custom scripts
that can be used to gather data. Each script can contain arguments that must be entered
for each data source created using the script (such as an IP address).
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. An example of this
would be populating a list with IP interfaces or mounted partitions on a server. Integration
with graph templates can be defined to enable one click graph creation for hosts.
A PHP-based poller is provided to execute scripts, retrieve SNMP data, and update
your RRD files.
Templates
Graph templates enable common graphs to be grouped together by templating. Every
field for a normal graph can be templated or specified on a per-graph basis.
Data source templates enable common data source types to be grouped together
by templating. Every field for a normal data source can be templated or specified on a
per-data source basis.
Host templates are a group of graph and data source templates that allow you to define
common host types. Upon the creation of a host, it will automatically take on the properties
of its template.
Graph Display
The tree view allows users to create "graph hierarchies" and
place graphs on the tree. This is an easy way to manage/organize a large
number of graphs.
The list view lists the title of each graph in one large
list which links the user to the actual graph.
The preview view displays all of the graphs in one large
list format. This is similar to the default view for the 14all cgi
script for RRDTool/MRTG.
User Management
User based management allows administrators to create users and assign different
levels of permissions to the cacti interface.
Permissions can be specified per-graph for each user, making cacti suitable for
co location situations.
Each user can keep their own graph settings for varying viewing preferences.
