One thing I noted was that I consistently have 6% of samples with
buffer fullness of zero while playing a song overnight.
I _think_ this is when we're playing out the end of the song during
playout_play or playout_stop.
I suggest that we not sample when in those playmodes since it's
acceptable to have an arbitrarily low buffer fullness when we're at
the end of a song.
Does this make sense?

Tomorrow's 6.2 nightly should include an extra plugin which collects
data on network and server health. Please try it and let me know what
you think. [Should appear in "settings" section of the home page]
The plugin collects data on key network and server metrics in the form
of logging the number of samples that fall within a certain range,
together with max, min and average values.
The Summary section attempts to summarise the health of a player by
looking at the data collected. This is based on thresholds build into
the plugin which decided whether for example the signal strength is
good or poor or intermittent. These need tuning - please let me have
your feedback on this.
The Player and Server performance sections below this show graphs of
all the data recorded.
Information gathered at present:
Per player:
- signal strength
- buffer fill
- congestion on control connection [user interface connection to
player]
Server:
- reponse time of server
- accuracy and length of timer tasks *
- length of scheduled tasks *
[* probably only of interest in diagnosing server issues within
plugins
and to developers etc]
Feedback definately appreciated - especially on the text descriptions
and on the thresholds used to trigger the summary status.
Data collection is only enabled if you turn it on via the plugin or
start the server with --perfmon. However I don't expect there to be
any noticable performance penalty of leaving it enabled.
Thanks to kdf for the help with the web page.
