RRD Preferences

Changes here will take effect when the plugin is started.

ItemDescription and Notes
Dump Interval seconds
Specifies how often data is stored permanently.
Throughput Granularity seconds
Specifies how often throughput data is stored permanently.
Note: if you change this value the throughput stats will be reset and past values will be lost. You've been warned!
Dump Hours
Specifies how many hours of 'interval' data is stored permanently.
Dump Days
Specifies how many days of hourly data is stored permanently.
Dump Months
Specifies how many months (30 days) of daily data is stored permanently.
WARNING: Changes to the above values will ONLY affect NEW rrds
RRD Update Delay
Specifies how many ms to wait between two consecutive RRD updates. Increase this value to distribute RRD load on I/O over the time. Note that a combination of large delays and many RRDs to update can slow down the RRD plugin performance

RRD Files Path
NOTE:
  • The rrd files will be in a subdirectory structure, e.g. /var/lib/ntop/rrd?/interfaces/interface-name/12/239/98/199/xxxxx.rrd to limit the number of files per subdirectory.
  • Do not use the ':' character in the path as it is forbidded by rrd
File/Directory Permissions
  • Private - means that ONLY the ntop userid will be able to view the files
  • Group - means that all users in the same group as the ntop userid will be able to view the rrd files.
    (this is a bad choice if ntop's group is 'nobody' along with many other service ids)
  • Everyone - means that everyone on the ntop host system will be able to view the rrd files.

WARNING: Changing this setting affects only new files and directories! Unless you go back and fixup existing file and directory permissions:
  • Users will retain access to any rrd file or directory they currently have access to even if you change to a more restrictive setting.
  • Users will not gain access to any rrd file or directory they currently do not have access to even if you change to a less restrictive setting. Further, existing directory permissions may prevent them from reading new files created in existing directories.
