Alert log messages and errors are not collected or seen in the Oracle dashboard (4302023)

Oracle alert log drilldown page is not collecting many of the alert log messages and errors.

The customer created an alert log filer which included brackets ("[]") with a server name within them. The filter functioned as a regular expression and caused all Oracle alert log lines with even just one of the characters matching to be filtered from the drilldown.

For example, the following filter would ignore any alert log lines containing the characters "T", "e", "s", "t", "v", "e", "r", "0", and "1"

.*[Testserver01].* enabled, any Oracle error lines which included a character listed between the square brackets in the filter were ignored.

RESOLUTION 1

Disable the Alert log filter containing the brackets

RESOLUTION 2

Delete the Alert log filter containing the brackets

RESOLUTION 3

Change the bracket characters to another character to avoid using the wildcard functionality in the regular expression.
