Why is net.udp.listen getting ZBX_NOTSUPPORTED?

[Mitch]

There are a lot of keys that are supposed to be supported that returning ZBX_NOTSUPPORTED

For instance

zabbix_server$ zabbix_get -s {our_dns_server} -k 'net.udp.listen[53]'
ZBX_NOTSUPPORTED


zabbix_server$ zabbix_get -s {our_web_server} -k 'net.tcp.listen[80]'
ZBX_NOTSUPPORTED

zabbix_server$ zabbix_get -s {our_ldap_server} -k 'net.tcp.service[ldap,127.0.0.1,389]'
ZBX_NOTSUPPORTED


Both server and agent are 1.8.3 on Centos5 (linux 2.6.18 kernel)

i believe net tcp & udp listen items will be supported on linux starting with 1.8.4...

1.8 documentation....

I thought that according to this 1.8 documentation, all these were already supported on the Linux 2.6 platform:

http://www.zabbix.com/documentation/...ed_by_platform

If it's only in 1.8.4, is their more granular documentation?

You need to go down one section to 4.19.4 and read the Comments section for net.udp.listen[port] where it says: "Supported since Zabbix agent version 1.8.4."

http://www.zabbix.com/documentation/1.8/manual/config/items#zabbix_agent


Edit: If it's any consolation, you could use net.tcp.port[,53] and/or net.tcp.port[127.0.0.1,80]

currently only completely new items have information about which version they appeared in. additional supported platforms are not documented separately at this time, and 1.8 documentation always is supposed to refer to latest 1.8

that's a very good point as well
although in some other cases supported platform changes wouldn't be that easily to deduce, here next table gives a very specific hint as of which version item is expected to be working
