perf logging:
. improve the integration with eZ5 non-pure-legacy mode:
  . test again logging on pages which do redirects: does it work or not?
      - redirects done via the Sf stack
      - redirects/terminations done via the Legacy stack
  . better documentation of the kernel hacks / config changes needed (or not) in new-stack mode (ex: how to log module_result/*)
. self-contained db logging
  . direct-to-db logging
  . import parsed data to db (and aggregate it to a data-cube)
  . module/views to display data from db
  . fetch functions to retrieve data when it's in the db
. more KPIs in std logger
  . allow module_result/* and content_info/* for ezp >= 5.0
  . add mail-sending tracers for all other versions than ezp 4.7
. more logging targets
  . allow using snmp traps as target
  . yoochoose trackers?

. improve existing logging targets
  . allow csv output to use comma instead of dot for float numbers
  . create a custom plugin for piwik to better visualize our data, and possibly store it in dedicated tables
    (see http://openelibrary.org/development/piwik-custom-data-tracking/)
  . for statsd logger: prepend url parameters to key name; use an (ini) default value instead of null for key name tokens
. improve php api
  . add new perf. measurement functions: increment/decrement value, measure time?
  . add new perf. measurement functions: flush to log now

. script to wget and measure a whole site
. add to extension some sample spreadsheets where to copy data into, that come with pre-made formulas to show eg. view-cache relevancy
. add some nice tutorial with common usecases and advanced features (usage of mod_unique_id to reconcile access logs and perf data if kept separate,
  site crawling via httrack + graphing with excel, logstash integration, ...)

. scripts to coalesce csv files with a given time slice (eg. 1 data point every N minutes) to facilitate producing graphs
. use eZDebug::appendTop(Bottom)Report for adding report info instead of using preg_stuff...


xhprof:
. fix typeahead find in "view" view
. fix: "invalid sort key" error in "view" view
. allow sorting by url (or other?) of view listing all xhprof runs
. cache parsed xhprof data when viewing same trace again
. add support for picking 2 runs for comparison (in 'list' view)
. avoid generating hkprof trace when viewing another trace
. push to upstream xhprof lib all our patches
. avoid fatal error if xhprof is off and startlogging is called
. show warning in gui if xhprof is disabled
. include xhprof.io / rewrite GUI on top of it (then declare it as dependency in composer.json)


munin:
. add to php script support for installing the munin plugin on its own
. take care about integer overflow when reporting page size (avg or plain sum)
. avoid parsing the log file 10 times in a row when there are 10 variables graphed
. improve eZ module/view which displays munin graphs:
   - better vertical sizing of iframe
   - use eZ as reverse proxy (needs better support for custom auth as well)
. munin multigraph to zoom in on single urls?


other tools:
. support cacti, collectd (see http://collectd.org/documentation/manpages/collectd-exec.5.shtml), dim_stat, mrtg, ganglia, ...
