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 poller_output_boost table
Enables direct insert of records into poller output boost with results in a 25% time reduction in each poll cycle.
Boost Debug Log
If this field is non-blank, Boost will log RRDUpdate output from the boost poller process.
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
Calculate Peaks Stats in Addition to Average Stats
This option will double the data collection time. If will use the MAX consolidation function and calculate statistics from the max values in each of the respective time ranges.
Number of DSStats Processes
The number of concurrent DSStats processes to use to use to process all of the Data Sources.
Daily Update Frequency
How frequent should Daily Stats be updated?
Hourly Average Window
The number of consecutive hours that represent the hourly average. Keep in mind that a setting too high can result in very large memory tables
