zabbix agent2 oracle monitoring always connects to oracle 1521 (default) port

[[email protected]]

Hi, I have oracle server set up on non-default port, wanted to have it monitored by zabbix agent2 installed on the same machine, however it always connects to standard 1521.
Macro setup on zabbix server:
{$ORACLE.CONNSTRING}=tcp://localhost:52482
{$ORACLE.USER}=ZABBIX
{$ORACLE.PASSWORD}=<mypassword for ZABBIX oracle user>
{$ORACLE.SERVICE}=kalypso

Fatal NI connect error 12541, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhos t)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ORA)(CID =(PROGRAM=zabbix_agent2)(HOST=kalypso)(USER=zabbix )))(CONNECT_TIMEOUT=3)(RETRY_COUNT=0))
TNS-12541: TNS:no listener

agent log: [Oracle] Connection failed: ORA-12541: TNS:no listener.

can anyone help?

i was configuring macros for oracle on server instead of host, i.e. in Administration->General->Macros menu. When i set those up in host definitions (Macros tab) everything started to work perfectly
