Monitoring System Log files

One way of monitoring system logs is using dmesg. This command helps you monitor messages logged by the linux kernel and its modules. We see the last few lines in the example below:

root@hostname:directory# dmesg
tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is on for TX and on for RX.
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
