Release Notes - 0.8.6

What's New?

Graph Zoom and Timespan features enable you to focus on different times on the graph by zooming in on a particular area or using one of the many provided timespan presets. It is now possible to select custom graph timespans using the DHTML calendar control. Users that rely on Cacti's bandwidth summation and 95th percentile features will appreciate the added ability to calculate a sum or 95th percentile over an arbitrary timespan.

Several Tree-Related Features including the ability to auto-sort any branch or tree itself and the ability to group any host item by data query index rather than graph template.

A Revamped Poller Architecture which supports variable log levels, multiple log destinations, auto data query recache detection, and host availability sensing. Cacti is now capable of spawning multiple simultaneous poller threads to increase the efficiency of the polling process. Most aspects of the poller (cmd.php and cactid) can be configured from the new "Poller" tab on the Cacti Settings page. For current users of Cacti, be sure to read below for important upgrade instructions regarding the new poller architecture.

Multiple Log File Destinations including syslog (Unix), Event Log (Windows), and a standard log file. Syslog/Eventlog support makes it easy to get notified when critical poller events occur. Various levels of log verbosity and detail settings allow you to choose exactly which events Cacti should store in its log making it easier to spot problems when they occur.

Upgrade Notes

IMPORTANT: Crontab/Scheduled Task Change

The file that is executed every 5 minutes to populate the graphs has been changed. Unix users will have to change their crontab entry and replace cmd.php with poller.php. The updated line will look something like:

*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1

(Windows update instructions go here)

Separate Cactid Distribution

For security and maintainence reasons, cactid will now be distributed separately from the main Cacti distribution.

New Default Log File Path

The new default log file path in Cacti is log/cacti.log. You will need to update anything you have looking at the old location or update the log file path under Settings -> Paths -> Cactid Poller File Path.

Beta Tester Thanks
