Zabbix Pollers and service issue

[Yousif282]

Hello
I Have a problem with my zabbix environment.
My setup consist of two physical zabbix server running as active passive using pacemaker
the servers specs are

40 Core Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
126 GB RAM

My database is a master-master mysql.
it also consist of two physical server, their specs are

40 Core Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
256 GB of RAM
18 TB of SSD storage

I have about 13,000 hosts and over 780,000 items
my NVPS is 5300

My problem is that my data pollers and unreachable pollers are always High
My unreachable pollers are stuck at 100% and data pollers are above 95 %

the other problem is that when i try ot fail over to my second zabbix server with pacemaker
the zabbix-server service on the fist one does not shut down properly and it get stuck and the only way to fail over to the second server is to shut down the server so the pacemaker can start the service on the other server.

Here's the My config file for zabbix server and mysql
also you can view the attached images for the performance graphs for a 1 month period

My zabbix version is 4.4.4 and i have one proxy server for testing.

I'd break up this two zabbix servers physical machines into VMs and have myself a bunch of proxies to separate the collect and preprocessing workload.

If anything more it helps to find issues in data collection with some segmentation.

Such change does not make any sense. All wjhat needs to be done is:
1) stop monitoring anything relse than zabbix server themeselv over zabbix server and add proxies
2) swiitch from zabbix agent passive monitoring to active one

What I said, mean the same as what you write about "stop monitoring anything relse than zabbix server themeselv over zabbix server and add proxies", but I took into account the size of the servers he has, and his need to keep a HA environment. I'm just trying to make myself clear, you don't need to reply to this.

Thanks for the reply,
I will try to move on to zabbix proxies
and change the zabbix-agent to passive checks
