RRD (Round Robin Database) file data types

There is a standard set of rrd databases containing stats for journal, system, shell. For each activity there is an independent rrd database which tracks a standard set of parameters, the details for which are listed below.

journal.rrd

  • active
  • creates
  • deletes
  • updates
  • uptime

system.rrd

  • diskfree
  • uptime

shell.rrd

  • active
  • friends
  • uptime

activity.<bundle_id>.rrd

  • active
  • buddies
  • instances
  • new
  • resumed
  • uptime

Factors affecting network bandwidth

The two primary factors affecting the network bandwidth are:

  • the size of the RRDs being synced
  • and the sync frequency.

RRD size

  • This is primarily controlled through RRA (parameters). I will upload more notes on this as I get to know RRD's better. (Anish)

Sync frequency

  • This is controlled by the update-timeout parameter in the sugar-client configuration.

Caution: The default RRD parameters and the sync frequency don't quite match up. The RRDs track usage statistics for around 8-10 days and the sync frequency is one hour! This needs to be tweaked appropriately while deploying in a production environment to save on bandwidth.
