Discussion

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process logs as required. Log processing failures include software/hardware errors, failures in the log capturing mechanisms, and log storage capacity being reached or exceeded. Notification of the storage condition will allow administrators to take actions so that logs are not lost. This requirement can be met by configuring the application server to utilize a dedicated logging tool that meets this requirement. Satisfies: SRG-APP-000359-AS-000065, SRG-APP-000360-AS-000066
