 Description   

After installing the new version of the pre-zabbix-2.1.0-30326 stopped working an item with dynamic indices that use macros.

not working example SNMP OID
IF-MIB :: ifHCInOctets ["index", "IF-MIB :: ifDescr", "{$ SNMP_IFDESCR}"]

в старых версиях работало

Comment by Victor Bashkirov [ 2012 Sep 27 ]

worked in the pre-zabbix-2.1.0-29194
noticed what does not work in pre-zabbix-2.1.0-29445

Comment by Eric Gearhart [ 2012 Sep 28 ]

Are you sure this isn't a duplicate of https://support.zabbix.com/browse/ZBX-4793 ? Dynamic indexes seem to be broken for a bunch of folks (me included)

Comment by Victor Bashkirov [ 2012 Sep 28 ]

I think problem in file src\libs\zbxserver\expression.c
function substitute_simple_macros(
...............................................
else if (macro_type & MACRO_TYPE_ITEM_KEY)
{
if (0 == strncmp(m, "{$", 2)) /* user defined macros */
DCget_user_macro(&dc_item->host.hostid, 1, m, &replace_to);
else if (0 == strcmp(m, MVAR_HOST_HOST) || 0 == strcmp(m, MVAR_HOSTNAME))
replace_to = zbx_strdup(replace_to, dc_item->host.host);
else if (0 == strcmp(m, MVAR_HOST_NAME))
replace_to = zbx_strdup(replace_to, dc_item->host.name);
else if (0 == strcmp(m, MVAR_HOST_IP) || 0 == strcmp(m, MVAR_IPADDRESS))

{ if (INTERFACE_TYPE_UNKNOWN != dc_item->interface.type) replace_to = zbx_strdup(replace_to, dc_item->interface.ip_orig); else ret = FAIL; }

else if (0 == strcmp(m, MVAR_HOST_DNS))

{ if (INTERFACE_TYPE_UNKNOWN != dc_item->interface.type) replace_to = zbx_strdup(replace_to, dc_item->interface.dns_orig); else ret = FAIL; }

else if (0 == strcmp(m, MVAR_HOST_CONN))

{ if (INTERFACE_TYPE_UNKNOWN != dc_item->interface.type) replace_to = zbx_strdup(replace_to, dc_item->interface.addr); else ret = FAIL; }

}
...............................................
can not understand the logic of the function
Why test the type of interface?

Confirmed. Broken by:

.......PS. ZBX-5397 fixed resolving of

{HOST.IP}

,

{HOST.DNS}

and

{HOST.CONN}

macros in item key parameters

Changed priority to Blocker.
