ZabbixProxy on VPS - Simple Checks fail
I have a problem whereby simplechecks and such do not seem to function from a Zabbix Proxy which is installed on a VPS.
ZabbixProxy1 = Installed on a VM (Virtual Machine)
ZabbixProxy4 = Installed on a VPS (Virtual Private System)
Both systems have Ubuntu 20.04 installed with all the latest updates.
The VM was installed using an official ISO image.
The VPS was installed using the supplied pre-install.
Doing a Zabbix “simple check” on the VM functions ok.
Doing a Zabbix “simple check” on the VPS fails. The HTTP and HTTPS services supposedly are down.
Doing a Zabbix “web scenario” on the VM functions ok.
Doing a Zabbix “web scenario” on the VPS fails with an error: “Timeout was reached”
For ZabbixProxies the same host was used to do the testing for.
On the commandline of both ZabbixProxies a wget command functions fine.
ICMP and “External check” do function on both ZabbixProxies.
I found out that “curl” was not installed by default on the VPS.
So I installed that too. It did not solve the “web scenario” though.
I suspect that there are packages missing on the VPS which ZabbixProxy needs. Therefore I compared the list of installed packages from both ZabbixProxies. There are differences, but I don’t know which packages could be needed to make it all function on the VPS.
The information in the documentation does not state which packages are needed:
https://www.zabbix.com/documentation.../debian_ubuntu
Is there a list available of all needed packages for a ZabbixProxy?
Or maybe someone knows what could be missing on the VPS ?
