Hi MKumar,

you can read and filter the logs stored on your hard disks via TMSH.

To become able to read logs older than the last 8 days you have to increase the logrotate.logage sys-db variable, so that your logfile are not getting auto-deleted after 8 day.

root@(f501)(cfg-sync Standalone)(Active)(/Common)(tmos) list /sys db logrotate.logage
sys db logrotate.logage {
    value "8"
}
root@(f501)(cfg-sync Standalone)(Active)(/Common)(tmos) modify /sys db logrotate.logage value 14
root@(f501)(cfg-sync Standalone)(Active)(/Common)(tmos) list /sys db logrotate.logage
sys db logrotate.logage {
    value "14"
}
root@(f501)(cfg-sync Standalone)(Active)(/Common)(tmos) 

Cheers, Kai
