Hello,

it looks like Zabbix is compiled without the redis plugin.

From /usr/share/doc/zabbix-frontend-php/templates/db/redis/README.md.gz
Test availability: `zabbix_get -s redis-master -k redis.ping`

# `zabbix_get -s redis-master -k redis.ping`
zabbix_get [2264555]: Get value error: cannot resolve [redis-master]

And the template indeed doestn't work.

Would be nice to have redis support enabled.

No, it looks like there is no special support for Redis in zabbix-agent.

You probably need (Golang-based) Zabbix Agent 2, which is not provided
by Debian package (yet).

That error indicates that your network have no "redis-master" host
(or that there is no DNS record for it).

That's hardly a surprise if "redis master" don't resolve...

Thanks for your fast reply.
So what's missing to enable Agent 2?

Whoops. So I didn't read the docs fully.
But now I get a different error:

zabbix_get [2294402]: Check access restrictions in Zabbix agent
configuration

Well this isn't a support channel, so I'll try to find it out myself,
what's now wrong.

Thanks again for your answer.

I think Agent 2 is not the issue.

Agent will only respond to requests from hosts listed in "Server=".

In the docs it's listed for Agent 2:

https://www.zabbix.com/documentation/5.0/manual/config/templates_out_of_the_box/zabbix_agent2

So I guess it's needed?
127.0.0.1 was allowed:

# zabbix_get -s 127.0.0.1 -k redis.ping
