Macro in item key

[otheus]

Error in documentation??

The 2.2 documentation https://www.zabbix.com/documentation...ed_by_location states that [tt]{HOSTNAME}[/tt] is depracated and [tt]{HOST.NAMEn}[/tt] should be used. But this is clearly wrong. With 3.0 server and 2.2 agent, the agent reports:

1232:20161118:001106.254 item [vfs.check_write[/archive/xlog/{HOST.HOST1}]] error: special characters "\, ', ", `, *, ?, [, ], {, }, ~, $, !, &, ;, (, ), <, >, |, #, @, 0x0a" are not allowed in the parameters

When I use [tt]{HOSTNAME}[/tt] in these items instead, everything works correctly. Note: these are custom items used in passive mode.

You should have used {HOST.HOST}, not {HOST.HOST1}. Neither {HOST.HOST1} nor {HOSTNAME1} will work in this context. The link you mentioned has some information on where macro index can be used.
