Oracle DBs: Monitoring the alert.log

We're currently testing Hyperic HQ as monitoring-tool for our oracle databases. We want it to scan the alter.log files for ORA- errors periodically and, if a new one is found, report the error through mail.

The current method we're using is this:

We set up a New Platform Service for the Server hosting the DB. Resource Type is Process. We set it up to querry the oracle smon process (State.Name.eq=oracle,Args.*.eq=ora_smon_INSTANCE) and enabled the service.log tracking.

service.log_track.include ORA-
service.log_track.files /ora/app/oracle/admin/INSTANCE/bdump/alert_INSTANCE.log

Then we set up an alarm.

If Condition: Event/Log Level(ANY) and matching substring "ORA-"
Enable Action(s): Each time conditions are met.

When we enable this monitor and insert a ORA- error into the .log file, Hyperic HQ sends us a Mail reporting an ORA- error happened and lists the -first- ORA- error that appears in the log. If we insert more errors Hyperic only reports the -total number- of errors that appear in the log, but no specifics, just a number.

- Triggering Condition(s):
If Event/Log Level(ANY) and matching substring "ORA-"
Log: /ora/app/oracle/admin/INSTANCE/bdump/alert_INSTANCE.log: Message 'ORA-' repeated 21 times

So, our question basicly boils down to: Is there a better/right way to do what we want to do?

Are you sure that the raw log file doesn't report this the same way? Some mail logs I've viewed will actually say "message repeated n times". Can you confirm what is listed in the raw logs?

Yes, the log reports every ORA- Error seperatly. Here are some excerpts:

Thu Feb 7 09:44:40 2008
Errors in file /ora/app/oracle/admin/INSTANCE/udump/instance_ora_19929.trc:
ORA-00600: internal error code, arguments: [17182], [0x0B6F41C08], [], [], [], [], [], []

Thread 1 advanced to log sequence 10531
Current log# 2 seq# 10531 mem# 0: /u01/oradata/INSTANCE/redo02m1.dbf
Current log# 2 seq# 10531 mem# 1: /u01/oradata2/INSTANCE/redo02m2.dbf

Errors in file /ora/app/oracle/admin/INSTANCE/bdump/instance_arc1_9854.trc:
ORA-16038: log 3 sequence# 10532 cannot be archived
ORA-19504: failed to create file ""
ORA-00312: online log 3 thread 1: '/u01/oradata/INSTANCE/redo03m1.dbf'
ORA-00312: online log 3 thread 1: '/u01/oradata2/INSTANCE/redo03m2.dbf'

So for every "event" it lists the date, some additional info i.e. where the error occured and the errorcode(s) itself (if it's an error that got loged), each in a seperate line. There's no summary like the one we get sent by Hyperic HQ anywhere in the logfile.
