zabbix_agentd reponds, zabbix_get returns ZBX_NOTSUPPORTED

[DSpencer]

Zabbix Server version 1.8.8 on CentOS 6
Zabbix Agentd 1.8.3 on CentOS 6

I am working on cleaning up our zabbix monitoring. I am checkingitems on templates and there are a number host that report the items as "Not Supported".

Most I have figured out most, but vm.memory.size[shared] had got me puzzled.

Running the zabbix_agentd on the host vm.memory.size[shared] returns [u|0] which is correct for this host.

Running the zabbix_get on the zabbix server vm.memory.size[shared] returns ZBX_NOTSUPPORTED.

I cannot figure out why zabbix server is unable to check vm.memory.size[shared]. All other modes work fine except for shared. I ran into similar problems with vfs.file.cksum[/foo/bar] and found it was a permission issue on the file being checked, but i cannot find the file or documenation about any specific file that vm.memory.size item checks. I did look into the /proc/sys/vm and systrl but did not find any answers.

Any help or suggestions would be greatly appreciated!

Puzzled about vm.memory.size[shared]

DSpencer,
I was scratching my head about this also and not sure if yours is the same issue but after researching it and finding the latest docs in the zabbix site I see that the vm.memory.size support for the parameter "shared" only works with the linux kernel 2.4. I'm running 2.6.

Hi DSpencer,

Please try to restart the zabbix agentd in your monitored server.

Actually I have same problem with you, when I trying to zabbix_get from my server the value is always 0.
