Recommend Performance monitor for interface

[urvininocente]

Hi,

I am configuring my network monitoring application to monitor my Cisco Routers and I am looking for recommended (best practice) thresh hold values for following the interface parameters (Ethernet interface):

Bandwidth Utilization (%)

Error rate (%)

Package discarded (%)

Any help, documents or advice  would be appreciated

Regards,

Here is my 2 cents

Don't think there is a one size fits all

Trunks and other connection between network devices

Bandwidth  Utilization 60% on full duplex 40% on half

Error rate  0

Package discarded 0

These interface should be absolutely clean, and you beter check Transmit load and Receive Load rather then Utilization

Userports

Bandwidth  Utilization 60%  on full duplex 40% on half

Error rate  5

Package discarded 5

Server ports

Bandwidth  Utilization 60%  on full duplex 40% on half

Error rate  1

Package discarded 1

I would say it is pointless to poll and monitor all ports for bandwith utilisation all the time.

Using rmon or something else to set (a couple of) thresholds and monitor that  is a much better idea

Not sure about a tool that could used for that however.

Cheers
