what agent did you use ?

fausp · March 20, 2021, 4:04pm

stephdl · March 20, 2021, 4:08pm

systemctl edit zabbix-agent2.service

then add

[Service]
RuntimeDirectory=zabbix
RuntimeDirectoryMode=0755

systemctl daemon-reload
systemctl start zabbix-agent2

stephdl · March 20, 2021, 4:12pm

zabbix-agent2 is not installed, you are using zabbix-agent

Yes I know but the zabbix-agent doesnt work just on one server… I would like to know why… I will install/test zabbix-agent2 later…

stephdl · March 20, 2021, 4:36pm

upstream bug that you have to patch yourself

mrmarkuz · March 21, 2021, 12:53pm

Maybe there’s an older testing version installed, you may try to reinstall nethserver-zabbix-agent with

yum reinstall https://mrmarkuz.dynu.net/mirror/devtest/nethserver-zabbix-agent-0.0.1-1.ns7.noarch.rpm

EDIT:

Thanks to @stephdl who patched the agent to create the needed directory /var/run/zabbix/ and the server (removing old agent config) so if possible reinstall both to test the most recent versions.

There is another problem:

BDW, it worked on a fresh installed server:

# Install mrmarkuz repo:
yum -y install https://mrmarkuz.dynu.net/mirror/mrmarkuz/7/noarch/nethserver-mrmarkuz-0.0.1-5.ns7.noarch.rpm

# Install Zabbix 5.0 LTS repo:
yum -y install https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

# Install Zabbix agent/agent2:

config setprop zabbix-agent2 status enabled

# Copy your plugins to the new folder of zabbix-agent2 (if you get custom plugins in your agent)
cp /etc/zabbix/zabbix_agentd.d/* /etc/zabbix/zabbix_agent2.d/

# The agent needs to know its server:
config setprop zabbix-agent2 ServerZabbix <my-server-ip-with-zabbix-agent-2>
signal-event nethserver-zabbix-agent-update

It seems nethserver-zabbix-agent is not installed.
Please try with yum install instead of yum reinstall.

You may need to enable the zabbix repo.

yum --enablerepo=zabbix install https://mrmarkuz.dynu.net/mirror/devtest/nethserver-zabbix-agent-0.0.1-1.ns7.noarch.rpm

Everything is green, thank you! -

fausp · March 22, 2021, 6:30pm

@stephdl - Please tell me what templates do you use on Nethserver with zabbix-agent2? I use these atm:

stephdl · March 22, 2021, 6:32pm

I use

ping (but not necessary)
module linux generic

I do not see the systemd template, you have to import it manually

fausp · March 22, 2021, 6:44pm

Got it, thank you!

mrmarkuz · April 9, 2021, 10:09pm

Released. Thanks for testing.

pike · April 10, 2021, 1:55pm

IDK, maybe this post

should be put there?
