NethServer Version: 7.9
Module: Zabbix 5.0
If your nice zabbix 5.0 tells you that the ValueCache is insufficient for the configuration and you cannot optimize any of the settings (lots of thing could be done for that) you can still increase you ValueCacheSize.
As default config, value is not specified. Currently I don’t know which is the default cache size.
Therefore, after copying from the custom template and this post about other things, there’s my little howto…
Do you already have a custom template for Zabbix?
If you’re unsure, you can access to ssh/terminal on your installation, go to / and fire up find -iname zabbux_server.conf
If the output is exactly like this
./etc/e-smith/events/nethserver-zabbix-update/templates2expand/etc/zabbix/zabbix_server.conf
./etc/e-smith/templates/etc/zabbix/zabbix_server.conf
./etc/e-smith/templates-custom/etc/zabbix/zabbix_server.conf
./etc/zabbix/zabbix_server.conf
with the directory /etc/e-smith/templates-custom/etc/zabbix/zabbix_server.conf already existing, you already have a custom template.
So verify your custom-template which is, edit (maybe backup?) the existing file and add the line
ValueCacheSize=64M
then launch the usual
signal-event nethserver-zabbix-update
If you don’t have any existing template
Thanks for sharing Mr Markuz
Create custom template dir:
mkdir -p /etc/e-smith/templates-custom/etc/zabbix/zabbix_server.conf
Create /etc/e-smith/templates-custom/etc/zabbix/zabbix_server.conf/90custom with following content:
# 90custom - additional settings
ValueCacheSize=64M
(or any value you consider suitable)
Apply config:
signal-event nethserver-zabbix-update
And checkup your install. Maybe… the value need some more tweaking.
