I see messages like below in ES server 1.7.1 log:
[2015-10-27 12:20:07,669][INFO ][monitor.jvm ] [my_host] [gc][young][67][20] duration [721ms], collections [1]/[1.7s], total [721ms]/[4s], memory [285.6mb]->[291.8mb]/[1.9gb], all_pools {[young] [27mb]->[280.4kb]/[66.5mb]}{[survivor] [8.3mb]->[8.3mb]/[8.3mb]}{[old] [250.2mb]->[283.2mb]/[1.9gb]}
Let's take the old
gen: {[old] [250.2mb]->[283.2mb]/[1.9gb]}
or $A -> $B / $C
is $A = value post-gc, $B = value pre-gc and $C = capacity? Or did heap allocation really grow as result of GC?
Thanks,
