Remote Access VPN Log Formats
The Cisco Secure Access remote access virtual private network (VPN) logs show the VPN session connection events, which are managed by the Secure Access VPN services. Some relevant fields to aid debugging and trouble-shooting VPN sessions include:
- Display Username for Failed Events – Significantly improves how quickly issues can be tracked and addressed.
- ASA Syslog Message ID Extraction Support – Offers detailed insights by identifying the specific sys-log messages used in the remote access logs.
- Device ID – Includes the device ID with every event, providing critical help to network administrators in numerous ways.
- Failed Events for Posture – Provides vital information for effective triage during failed connection attempts.
