Why Performance Monitoring? (1)
Start with Fault Management
Machines up and running?
Services up and running?
Metrics ok (thresholds)?
...
current timestamp
“ok” or “not ok”

“good looking”

No system was down, but
“bad looking”

zoom in to get exact timeframe

history
matters!

DB
outage!
filesize
increases!
trend

rrdrrdrrd
PBX

Single server setup, agent-less
Browser based
Fast, extensible data collector
Template engine
Plugin Ecosystem
Scalable → 1,000,000 data sources

Data Input Method (script) fetches data, e.g. temperature
Data Query fetches tabular data e.g. Interface stats
Data Template storage pattern for data == rrd file
Graph Template defines graphical layout for display
Host Template groups graph templates
Plugin add new functionality to Cacti:
- Threshold Alerts
- Tabular reports
- Weathermaps
- Dashboards

English, Bulgarian, French, German, Spanish, Swedish,
Russian, Japanese, Trad. Chinese,
Translators welcome!
Automatic language detection
Time zone support
Support for i18n for plugins

Cacti - Teaser

The Future (Integration)
Built-in Plugin Architecture, finally!
Command Line Interface
Completely rewritten CLI support
to e.g. allow interfacing a CMDB
Works on Data queries, Devices, Graphs, Trees
User and permission support
Template Import
... and more ...

The Future (Full RRDTool Support)
support almost any available RRDTool feature
Right axis, manual/automatic scaling, grid-fitting
Every colortag, full font support, watermarks, ...
Templated x-grid support (time axis)
Dash support, borders, font smoothing,
pango markup
COMPUTE data source

The Future (AJAX and CSS)
jQuery
e.g. Colorpicker, jQuery UI
Improved admin performance via AJAX
Autocomplete fields
to avoid loading e.g. 100s devices in a dropdown
Drag 'n' drop item reordering
Tabbed views, Re-sizable menu and columns
new tree design

The Future (Scalability)
Cacti goes large scale
Multiple installations > 100,000 data sources
Biggest known > 1,000,000 data sources
required resources:
BOOST plugin, predecessor of rrdcached
fast bulk rrd updates
(disk performance!)
Use of MySQL memory tables
