During an InTrust Gathering job the following warning is experienced, "Some events not collected because the Ignore Events option was selected"
The "Ignore Events" option is enabled on event log in question on the gathering policy in use.
Clear the "Ignore Events" checkbox on the datasource mentioned in the warning under the Gathering policy used by the Gathering job.
The InTrust Agent will collect from the point last collected from in the log. The option mentioned above should not be used in scheduled gathering jobs to avoid the chance of missing events.
