Log monitoring

[stefano]

Hi all,

I'm trying to use zabbix to monitor log files of oracle creating a trigger everytime log file has ORA- line.
I've created, as from manual, an item with key
log[/opt/oracle/admin/TDW/bdump/alert_TDW2.log]

type: ZABBIX agent (active)
update interval: 5
status: active

Then I've created a trigger defining expression:
{itsm-cldb1c:log[/opt/oracle/admin/TDW/bdump/alert_TDW2.log].str(ORA)}=1
severity: high.

If I make
echo "ORA-93197 DEMO" >> /opt/oracle/admin/TDW/bdump/alert_TDW2.log
no alarm is generated from zabbix.

How can I debug?
Agent is active:
22008:20070925:163600 zabbix_agentd started. ZABBIX 1.4.2.
22009:20070925:163600 zabbix_agentd collector started
22010:20070925:163600 zabbix_agentd listener started
22011:20070925:163600 zabbix_agentd listener started
22012:20070925:163600 zabbix_agentd listener started
22013:20070925:163600 zabbix_agentd active check started [serverip:10051]


Thanks
Stefano
