Release Notes - 0.8.6e

Important Security Fixes

Additional checks have been added to prevent potential SQL injection attacks from unchecked user input. Additionally, two security holes regarding potential cross site scripting attacks have been closed. Both of these vulnerabilities have been disclosed by the iDEFENSE security group.

Important Bug Fixes

The minimum and maximum value fields for data sources now allow unknown values (U) which can be used to represent an undefined upper or lower bound.

Data input method field checking is now handled properly for data templates. This bug was responsible for causing the infamous "Duplicate data source" error in previous versions.

When running a poller with many concurrent processes, gaps would appear on the graphs for certain users. The code responsible for this bug has been removed from the poller.

Multiple issues with RRDtool 1.2 support were addressed related to the graph zoom feature, fonts, and graphs using the STACK item.

What's New?

Basic filtering functionality has been added to the devices screen which should make it more manageable for large installations.

Additional support for RRDtool 1.2 fonts has been added to both the global and user settings screens.

When deleting a device, if data sources are kept, they are now disabled to prevent issues with the poller. In addition, the ability to enable and disable data sources has been added to the user interface.

Upgrade Notes

This version introduces multiple SQL changes that users should be aware of. While none of these changes are major, creating a backup of your Cacti database prior to upgrading is always recommended. The individual changes are listed below.

  • Quite a few unused indexes have been dropped for performance and storage reasons.
  • Changes have been made to the graph and data source tables to allow for logarithmic upper and lower bounds.
  • A few indexes have been added to the graph tree tables to help improve the rendering time of the graph tree.
  • A few indexes have been added to help the performance of the "Clear Poller Cache" function.

Update 06/22/2005: For users of RRDtool 1.2, version 1.2.2 or higher is required in this version. This is due to additional support that has been added for RRDtool 1.2.
