Before RRD On-demand Update Can be Cleared, a poller run must always pass
How Often Should Boost Update All RRDs
When you enable boost, your RRD files are only updated when they are requested by a user, or when this time period elapses.
Number of Boost Processes
The number of concurrent boost processes to use to use to process all of the RRDs in the boost table.
Maximum Records
If the boost output table exceeds this size, in records, an update will take place.
Maximum Data Source Items Per Pass
To optimize performance, the boost RRD updater needs to know how many Data Source Items should be retrieved in one pass. Please be careful not to set too high as graphing performance during major updates can be compromised. If you encounter graphing or polling slowness during updates, lower this number. The default value is 50000.
Maximum Argument Length
When boost sends update commands to RRDtool, it must not exceed the operating systems Maximum Argument Length. This varies by operating system and kernel level. For example: Windows 2000 <= 2048, FreeBSD <= 65535, Linux 2.6.22-- <= 131072, Linux 2.6.23++ unlimited
Memory Limit for Boost and Poller
The maximum amount of memory for the Cacti Poller and Boosts Poller
Maximum RRD Update Script Run Time
If the boost poller exceeds this runtime, a warning will be placed in the cacti log,
Enable Direct Population of Boost Table
Enables direct insert of records into poller output boost table with results in a 25% time reduction in each poll cycle.
Enable Boost Debugging
If set, Boost will log debug information directly to the Boost log file. Please note, enabling can cause a high I/O rate on the local file system.
Image Caching
Enable Image Caching
Should image caching be enabled?
Location for Image Files
Specify the location where Boost should place your image files. These files will be automatically purged by the poller when they expire.
Data Sources Statistics
Enable Data Source Statistics Collection
Should Data Source Statistics be collected for this Cacti system?
Data Collection Method
Data Source Statistics can use a legacy method where it will determine peak and average values, or an advanced mode which will calculated several additional statistical values in addition to peak and average. Using All Statistical Metrics can place additional CPU and IO load on the system.
Peak/Average Only
All Statistical Metrics
