Filter or modify displayed syslog?

[PutnamCountyIT]

My syslog on all nodes is basically page after page of:

Dec 12 13:03:27 putsproxp10 corosync[3147]: [KNET ] pmtud: Starting PMTUD for host: 7 link: 0 Dec 12 13:03:27 putsproxp10 corosync[3147]: [KNET ] udp: detected kernel MTU: 1500 Dec 12 13:03:27 putsproxp10 corosync[3147]: [KNET ] pmtud: PMTUD completed for host: 7 link: 0 current link mtu: 1397


Is there a way to filter or modify what is displayed so I can scroll and see either more relevant messages or errors?

cat /var/log/syslog | grep --invert KNET| more or tail -100 /var/log/syslog | grep --invert KNET?
