Performance Values
The following counters are returned by the STATS command:
QueueLength (unsigned 64bit integer)
Number of nodes currently enqueued in the update queue.
UpdatesReceived (unsigned 64bit integer)
Number of UPDATE commands received.
FlushesReceived (unsigned 64bit integer)
Number of FLUSH commands received.
UpdatesWritten (unsigned 64bit integer)
Total number of updates, i. e. calls to rrd_update_r, since the daemon was started.
DataSetsWritten (unsigned 64bit integer)
Total number of "data sets" written to disk since the daemon was started. A data set is one or more values passed to the UPDATE command. For example: 1223661439:123:456 is one data set with two values. The term "data set" is used to prevent confusion whether individual values or groups of values are counted.
TreeNodesNumber (unsigned 64bit integer)
Number of nodes in the cache.
TreeDepth (unsigned 64bit integer)
Depth of the tree used for fast key lookup.
JournalBytes (unsigned 64bit integer)
Total number of bytes written to the journal since startup.
JournalRotate (unsigned 64bit integer)
Number of times the journal has been rotated since startup.
