Cisco ASA logs view

[Raheel qaiser]

Hello,

 I have Cisco ASA 5510 , i can access and monitor Real time Logs in it but i am unable to get old (Previous Months) logs.

Please guide me to get its old logs in it.

Thanks

The ASDM is not the right tool for long-time analysis of events. You have to setup a syslog server in your network and configure your ASA to send the logs to that server.

As Karsten noted... plus you appear to have more verbose logging enabled (informational level 6 events shown). That will make the local log buffer fill up even more quickly. You can adjust the local buffer size but it's not really designed to be used for historical reporting or forensic analysis

Unless you are troubleshooting or have a legal / regulatory requirement, it's recommended to log only up through level 4 or 5 (warnings and notifications respectively)
