- Threshold Alerts- Tabular reports- Weathermaps- Dashboards

The Future (Scalability)

Cacti goes large scaleMultiple installations > 100,000 data sourcesBiggest known > 1,000,000 data sources

required resources:BOOST plugin, predecessor of rrdcachedfast bulk rrd updates (disk performance!)Use of MySQL memory tables

55thecompleterrdtoolbasedgraphingsolutionthecompleterrdtoolbasedgraphingsolutionCactiCacti

The Future (Integration; 0.8.8, 0.8.9)

0.8.8 (current): Built-in Plugin Architecture, finally!0.8.9 (soon): Command Line Interface

Completely rewritten CLI support to e.g. allow interfacing a CMDBWorks on Data queries, Devices, Graphs, TreesUser and permission supportTemplate Import... and more ...

56thecompleterrdtoolbasedgraphingsolutionthecompleterrdtoolbasedgraphingsolutionCactiCacti

The Future (Full RRDTool Support; 0.8.9)

0.8.9 (soon):support almost any available RRDTool feature

Right axis, manual/automatic scaling, grid-fittingEvery colortag, full font support, watermarks, ...Templated x-grid support (time axis)Dash support, borders, font smoothing, pango markupCOMPUTE data source

57thecompleterrdtoolbasedgraphingsolutionthecompleterrdtoolbasedgraphingsolutionCactiCacti

The Future (AJAX and CSS; 0.8.9, ...)

jQuerye.g. Colorpicker, jQuery UI

Improved admin performance via AJAXAutocomplete fields to avoid loading e.g. 100s devices in a dropdownDrag 'n' drop item reordering

Tabbed views, Re-sizable menu and columnsnew tree design
