There's opinion about statistics which already implemented (memcache, apc)
I've try to make eAccelerator stats but stucked with uptime and hits ...
Suppose apc and memcache stats are wrong ( total values are per backend not BIN)
Idea to count stats in backend keys (what todo with DB ?)
1) check 'bin_first' key for first request if non then write current time() - store $bin_first
2) uptime = time() - $bin_first
3) sets should be counted in 'bin_set'
4) gets should be counted in 'bin_hit' and 'bin_miss'
5) Other values can be counted from previous
In comments I'll try to post code

Suppose there's no clean solution

slantview commentedI got some ideas for this now, and I am going to be implementing them soon. Keep an eye out.

nick_vhDuring Drupalcon DC I took quite some time to figure out cacherouter and its statistics.
I made some statistics available for the DB mode and planning to do more for the other engines.
So what changed?
- added stats function in the base class
- added first cache item/ last cache item
- implemented memory in use by cache (in KB)
- implemented memory available (extra disk parameters)
- implemented how many sets
- some overall statistics smalltalk
- fixed whitescreen in admin (theme issue thanks to John Van Dyk, don't know his nickname altough he's a famous guy :) )
If you guys have any questions or comments, shoot!

nick_vhAnd we should seriously think about the effects of some statistics we would like to implement. This is not possible for all the engines and the way it's implemented now is not flexible enough to give more engine specific details.
Would like to see more seperated details.

andypostWhy not implement internal data structures (maybe in apc xcache eacc if avail) to count hits|misses

Comment #8
nick_vhIs there any update on this. Is this still required? Did not follow cacherouter for a while but I am willing to do something about it if somebody wants to write a roadmap about what is necessary?

andypostStatistics now live in different module #760056: Steal this module - Cache Router Statistics
