A large number of items are : ZBX_NOTSUPPORTED

[velda]

Both server and client are CentOS6U5.
On both agent is 2.2.5.
Server is also 2.2.5.

For many (crucial) items, when testing directly on client OR server I get :
# zabbix_agent -t "system.cpu.load[<cpu>,<mode>]"
system.cpu.load[<cpu>,<mode>] [m|ZBX_NOTSUPPORTED]
# zabbix_agent -t "system.cpu.util[<cpu>,<type>,<mode>]"
system.cpu.util[<cpu>,<type>,<mode>] [m|ZBX_NOTSUPPORTED]
# zabbix_agent -t "system.sw.os[<info>]"
system.sw.os[<info>] [m|ZBX_NOTSUPPORTED]
# zabbix_agent -t "vm.memory.size[<mode>]"
vm.memory.size[<mode>] [m|ZBX_NOTSUPPORTED]
# zabbix_agent -t "net.tcp.service[service,<ip>,<port>]"
net.tcp.service[service,<ip>,<port>] [m|ZBX_NOTSUPPORTED]

And as per matrix they should work, but they don't.
In both cases Zabbix agent is connected (green letter "Z").

What am I doing wrong?

"as per matrix they should work" - what matrix do you mean?

When zabbix_agent -t is run, it launches a new copy of zabbix_agent, tries to get item value and exits. The thing is, that some values, e.g. cpu load, can not get obtained in that way - they require zabbix_agent to run for some time and observe the system. That's probably why you are getting NOTSUPPORTED values here.

Silly question: I hope you are using the real words for <cpu> and for <mode>, not their substitution from example?

like

system.cpu.load[percpu,avg1] (real example) instead of

system.cpu.load[<cpu>,<mode>] (general description from documentation)

Also take a look on page Items supported by platform, because some Items doesn't work on all platforms in the same way.

Thank you

THNKS for replies.
I have not solved this, but have found a workaround.
I remove Template zabbix agent from the host, and add Template Linux OS, and get all the items that I need.
PS those two Templates can not coexist on the same host (collision of items).

I believe by default the zabbix agent template is linked to the Template Linux OS, which is why you can't (and don't need) to apply them both.

Thank you.
I have not found that mentioned anywhere.
I must confess that I am rather disappointed by the Zabbix documentation....

The documentation is actually pretty good, though it's not the easiest to navigate. Honestly like with most things in IT I find google/bing to be the best way to find out how to do what I need to do.
