Grid Control monitoring a particular logfile

Question

Hi all,
I have a doubt, is it possible to Grid Control monitor a specific log file?
I have a log file where a register a script execution status, is it possible to raise an alert on Grid control just keeping the eyes on this file ?
Thanks in advance,
Regards,

Yes.
Create an external table for that logfile, then create a user defined metric that queries the table to retrieve the execution status results, and define key values in that metric to raise warning or critical alerts based on the execution status.
For example, checking for success on a data pump job (admittedly contrived and inefficient) with a logfile called 'impdp.log' sitting in /tmp:
sqlplus / as sysdba
create or replace directory TEST_EXTERN_DIR as '/tmp';
grant read on directory TEST_EXTERN_DIR to someuser;
exit;
sqlplus someuser/somepassword
create table myextern ( string varchar(255) )
organization external ( default directory TEST_EXTERN_DIR
access parameters ( records delimited by newline ) location ( 'impdp.log' ) );
select * from myextern where string like 'Job%completed%';Then create the user-defined metric, in this case as a string metric run by someuser with a comparison operator of CONTAINS with a warning value of 'error' and a critical value of 'fail', set the metric to run as frequently as necessary along with any response actions necessary if desired.
