Are there a large number of patch panels between the switch and the server? Are the cables between devices and patches hand made? Are the interfaces on the server and the switch free of errors, dropped packets overruns collisions etc? Is there a speed or duplex mismatch?

Switch model is 3560. Actually Im monitoring: Cpu usage. Memory usage. Enviroment parameters Interface status (only up and down ports) with check_ifstatus. So, is there any other pluging to add to my schedule? Something I can use to figure out what the problem is ? Is there any other plugin to check ethernet link quality? like packets, arp table problems .... Any suggestion will be nice, Thank you in advance, bye Leo. ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
