I have MRTG with RRDTool configured to monitor the bandwidth on a switch, it is set to measure the traffic in bits. For the interface I need monitored it is showing this:
Description: GigabitEthernet2/0/25 ifType: ethernetCsmacd (6) ifName: Gi2/0/25 Max Speed: 1000.0 Mbits/s
Which is correct, it is a gigabit switch. However, on the graph it is showing 84.938Mbps out, which is not accurate, it is more like 849.38Mbps.
How do I get it to display the proper values?
I am using MRTG + RRDtool to monitor the bandwidth on each switchport of a Cisco Catalyst 2950 via snmp. Is MRTG capable of generating an hourly graph? With RRDtool I was able to set the interval to 1 minute in hopes of getting a more detailed graph, but the shortest timeframe the graph is 'Daily' graph (5 Minute Average) and the image is too small.
What I am looking to get out of this: I am looking to be able to visually monitor all of the switch ports and tell when port begins to have unusually high traffic, in real time (1 minute interval of snmp poll, graphs generated, and page refreshed).
I have a server with Adaptec HostRaid controller. It has 2x 2TB drives. If I go to create a RAID0 array (striped), it will set the array's capacity to 2TB, when I go to create a RAID1 array (mirrored, and what I want to use), it sets the array's capacity to 1023GB instead of something closer to 2TB. The utility shows both drives as 1.8TB, what do I need to do to create a ~1.8TB RAID1 array?
