Send 1000 values for trapper item with preprocessing, each 1 MB
See that 771 MB is consumed until malloc_trim is called
771.17 Mb ./sbin/zabbix_server: preprocessing manager #1 [queued 1, processed 3 values, idle 5.154571 sec during 5.155190 sec]
Check diaginfo and see that there is no helpful information:
== preprocessing diagnostic information == Cached items:5 pending tasks:0 finished tasks:0 task sequences:0 time:0.000530 Top.sequences:
Expected, it should be possible to identify items that received many values at once to identify what causes such high peak memory usage
== preprocessing diagnostic information == Cached items:5 pending tasks:0 finished tasks:0 task sequences:0 time:0.000530 Top.sequences: Top.peak: 1278554:20241127:154042.942 itemid:47740 tasks:1000
Actual:
It is only possible to identify such items when they are being processed for example:
== preprocessing diagnostic information == Cached items:5 pending tasks:165 finished tasks:0 task sequences:1 time:0.010465 Top.sequences: itemid:47740 tasks:168
This could help when diagnosing issues as ZBX-25050
