Hi All, I have just started learning and working with Ignite and I'm about to rise IGNITE JIRAs for next requirements. Could you please check maybe there are already exists. Would it be significant overhead for a cluster?
#1 For tuning system performance it'd be great to get detail information about memory and IO that using for cache and partition level. For example, it's possible to save (or share via bean ?) every 15-30-60 minutes "metric report" with main checkpoints: > * How many DataPages and IndexesPages are exist in memory and LFS? > * How many pages were evicted, loaded since last report (cluster start)? > * How many pages were presented in every free list? > * How many MIN, AVG, MAX direct, indirect counters are in pages? > * How many entities are in the cache, partition and what size they are? > * How many get, put, update operations were executed? #2 With information from "metric report" it'd be possible to analyse memory consuming and estimating system limits. For example, WebConsole can show information for every cache: > how fast has it grown? > how long it'd be possible to keep all data in memory? > when should be added new hard disks? Thanks a lot, Sergey
