Hi There everyone I am trying to monitor our SAN uplinks as we suspect that we have a bottleneck. I have set up MRTG to monitor the 4 switch ports in question, but I am seeing some strange results in the max and average bandwidth fields. I would expect the max data value to be constant for all the graphs daily, weekly, monthly yearly. Instead I have daily=96MB, weekly= 24.6 MB monthly = 11.4MB - this can't be right??? Im currently sampling every minute I am trying to use snmpv2c as they are gigabit interfaces - have I set this up right??? I have turned off scaling for all the graphs except for yearly as we need to pick up the spikes in bandwidth usage and a sample section for my config file is below. All the monitored ports are the same config as the one port shown below # Created by # /usr/bin/cfgmaker xxx.xxx.xxx.xxx ### Global Config Options # for UNIX # WorkDir: /home/http/mrtg # for Debian WorkDir: /var/www/mrtg # or for NT # WorkDir: c:\mrtgdata ### Global Defaults # to get bits instead of bytes and graphs growing to the right Options[_]: growright, bits EnableIPv6: no ###################################################################### # System: xxxx # Description: ProCurve J8693A Switch 3500yl-48G, revision K.13.63, ROM K.12.17 (/sw/code/build/btm(t3a)) # Contact: Infrastructure_Team # Location: T0_Equipment_Room ###################################################################### ### Interface 41 >> Descr: '41' | Name: '41' | Ip: '' | Eth: '00-17- a4-89-a2-57' ### Target[xxxxxx_41]: 41:[email protected]:::::2 SetEnv[xxxxxxxxx]: MRTG_INT_IP="" MRTG_INT_DESCR="41" MaxBytes[xxxxxxxxx]: 1250000000 Unscaled[xxxxxxxxxx]: mwd Title[xxxxxxxxxxxx]: Traffic Analysis for 41 -- sst0b PageTop[xxxxxxxxxx1]: <h1>Traffic Analysis for 41 (ge/0) -- sst0b</h1> <div id="sysdetails"> <table> <tr> <td>System:</td> <td>sst0b in T0_Equipment_Room</td> </tr> <tr> <td>Maintainer:</td> <td>Infrastructure_Team</td> </tr> <tr> <td>Description:</td> <td>41 sct0c-ge0 </td> </tr> <tr> <td>ifType:</td> <td>ethernetCsmacd (6)</td> </tr> <tr> <td>ifName:</td> <td>41</td> </tr> <tr> <td>Max Speed:</td> <td>125.0 MBytes/s</td> </tr> </table> </div>
Can someone help explain where I have gone wrong?
