Hi , can I reboot the host server using the Zabbix script, please I need to add a script that will reboot the host server.

[@initmax1]

Yes you can via actions. But firstly you need to create script in Alert > Script first.

I must disagree with you, the process is different from version to version and it is complicated. I have been using Zabbix since version 4. and everytime i get into upgrade it gets into firefighting mode.
this time from 6.0 to 7.0. Repos are not complete for ubuntu 20.04 I had to upgrade to 22.04 to be able to install, then i ran into a database error [Z3005] query failed: [1118] Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs [alter table `media_type` add `provider` integer default '0' not null].
without a known solution.
So sorry to say no it is not the same. for now, I will leave 6.0 as is to avoid the firefighting again.

I spun up a vm with ubuntu 22 on it to test out zabbix 7 with a fresh install. The agent crashed every five minutes, until I downgraded the agent on the server to 6, then it (the agent) became stable. Mostly 7 runs fairly well, however the vm has super high cpu load, and very little cpu usage. Out of the box 4 gigs ram, 4 cores, and 50 gigs of HD space, the exact same environment as my zabbix 6 server, but I already have had to delve into the weeds to fix performance issues.
I am now burning the vm running 7 to the ground and sticking with my functional and much less headache free server 6 setup. In a year or so I'll give 7 another chance, but I don't get a big enough budget to waste my time with this level of bug fixing.
