Fujitsu Siemens ServerView and SNMP Monitoring

monitoringsnmp

I want to monitor the temperature of a couple of our servers, and since they're Fujitsu Siemens servers with ServerView installed I decided to check if SNMP was an option, and apparently it was.

However, I can't seem to figure out which OID to get, or even in which MIB to look for this information. As usual, the documentation seems to be pretty scarce or at least vague.

Concrete information on this case would be welcome, more than anything, but if you would have tips on how to look for the right OIDs in general that would probably help me on my way as well as I don't have a clue how to properly go about it right now.

Thanks

What monitoring software are you using (Cacti, Munin, Nagios, Zabbix, other)? It may have built-in or community-contributed templates for your particular server.

Have a look on the manufacturer's website for MIBs relating to the hardware sensors (disk, CPU etc. are normally reported by the OS) - otherwise, snmpwalk a server and see if you can find anything that might correspond to temperature, keeping in mind the units may not be what you expect.

Router – Monitoring router bandwidth usage via Nagios and SNMP

I did this with a cron script, stores current value in a temp file then next time uses it to calculate bandwidth utilization since last run.

#!/bin/bash

email_address=""
router_ip=""

# 80% BANDWIDTH [ (384000bps) 48,000Bps ] - 20% = 38,400 Bps
alertBW="76800"

lastBWFile="/var/log/ciscoGW.log"
lastBW=`cat $lastBWFile | awk '{print$2}'`
lastTime=`cat $lastBWFile | awk '{print$1}'`

curBW=` snmpget  -c snmap_name -v 1 $router_ip IF-MIB::ifOutOctets.2  | awk '{print$4}'`

let diffBW=$curBW-$lastBW
#echo "Diff BW: $diffBW"
timeNow=`date +%s`
let diffTime=$timeNow-$lastTime
let alertBW=$alertBW*$diffTime

echo "$timeNow $curBW" > $lastBWFile

if [ $diffBW -gt $alertBW ]; then
#       echo "Over limit!"
        echo "Bandwith used over $diffTime seconds: $diffBW" | mail -s "BANDWIDTH OVER LIMIT!!!!" $email_address
fi

Since I was more interested in actual peaks I've since moved to using rrdtool:

#start 15 minutes ago
#end 5 minutes ago since rrdtool queries every 5 minutes 
rrdtool fetch $FROM MAX -s -900 -e -300

SNMP Bandwidth Monitoring – Billion Router

Instead of using snmp, you might get more information out of netflows. If your device can't generate netflows, you can generate your own if you can port-mirror the interesting interface on your router (presumably, the inside or trust interface).

Here are my notes on installing fprobe and nfsen, which in this configuration generates and then analyzes netflow information.

However you still won't be able to get specific target URL information out of this configuration. For that you need a proxy or some software that reads the network stream and can pick URLs out of the passing requests. (If anyone knows of such software, I would be very interested in hearing about it!)
