Hello @Krishna Reddy Malem,

The logs are stored in memory and you should sent them to a remote syslog server. They are typically stored in memory, and the router may have limited storage capacity for logs. The logs are accessible through the CLI. 

To archive logs and send them to a remote location, you can set up a syslog server for log collection. The remote syslog server will collect and store logs as configured. 

logging x.x.x.x (where x.x.x.x is the IP address of your syslog server)
logging trap <severity_level> (specify the log severity level)

Thanks.
I have setup the syslog server and followed the above steps and able to see logs(tried deleting the VRF and saw one entry in log file).
Can you please let me know how we can see all the logs, for example:
ERROR logs, faulty Hardware messages, high usage of CPU and memory messages, core dumps, configurations messages etc.
Thanks in advance.
