Node:Measured Properties, Next:Writing Clients, Previous:Membership visibility, Up:Top
The server measures a number of properties, and can return information
about them to a client via the
request. A server implementation may include experimental
properties, whose name should begin with
X-. All other
properties should be defined in this chapter.
Some of the properties that are suggested here might prove to be too
hard to measure efficiently, or might prove to expose too much
information. In that case, a server may select to not implement them.
Clients must be prepared to receive a
undefined-measurement error if they call
with a value that wasn't received from
For each measured value, both the levels and the ascent and descent rates are returned. See Stats, for more information.
Ascent and descent rates are always normalized to a number of events per 100 seconds.
