Release Notes - 0.8.6h
Important Bug Fixes
Although not necessarily a bug in Cacti, numerous users reported that graphs break when a graph item of type AREA, STACK, LINE1, LINE2, or LINE3 with no color is specified. Note that this is due to additional checking added in RRDtool which will cause a graph to fail if legend text and no color is specified for the graph item.
Various issues related to invalid character handling have been addressed related to user management and template exporting.
The use of hostnames prepended with TCP: now work correctly, which is necessary when an SNMP agent is using TCP rather than UDP.
Additional checks have been added to the graph export code to prevent it from deleting non-Cacti related files before the export process is initiated.
What's New?
The graph template and data template pages now have full filtering and pagination support.
Support for MySQL 5.x-based servers has been added.
The 95th percentile functionality has been extended to support arbitrary percentages (Nth percentile). This enables a user to add an 80th percentile line to their graphs for instance. Also by popular request, the 'aggregate' variable type has been added which allows users to use 95th percentile on summation graphs.
Multiple command line scripts have been added for common repetitive or lengthy processes in Cacti. These include copying a user, rebuilding the data query index cache, and rebuilding the poller items cache.
Upgrade Notes
A few minor database tweaks have been made in this version, detailed below.
- The columns that store device uptime statistics have been converted from a floating point number to a decimal.
- The length of the IP column in the user log table has been extended to allow for IPv6 address.
- To address the RRDtool 1.2 empty color issue outlined above, all AREA, STACK, LINE1, LINE2, or LINE3 graph items with no color defined will have their legend text (text format) set to "".
