How should zabbix and postgresql be configured so that Zabbix-server can easily handle more than 1500 hosts?

Question

PostgreSQL

Have zabbix-server on server machine 6 cores/12 threads, 12 gb ram, hdd 1 tb, and zabbix-server and posgresql are on the same machine, currently 1856 hosts, 45756 items and 19400 triggers, system feels pretty not bad, now there are problems with housepeeker - oh, (cleaner), actually the question is in the table of contents? little experience with this system, tell me how to tune the system?

Answer 1

Housekeeping when using postgres can be easily replaced by partitioning tables and then dropping them.
In general, on such a scale, it is probably more correct to use an SSD.
