Monitoring Data Synchronizer using SNMP (like MRTG)


August 31, 2011 3:49 pm





You can graph the actual number of connected devices to your Data Synchronizer server(s) using a standard SNMP tool like MRTG (Multi Router Traffic Grapher), see: MRTG is part of the software portfolio of your OES/SUSE Server. Just use YaST to install and configure it.

  1. On your Data Synchronizer Server install & configure the product “net-snmp”.
  2. Open the firewall for 161 UDP (just for your monitoring machine)
  3. Allow access by adding a line like
    rocommunity public IPAddressOfMonitoringMachine

    to “/etc/snmp/snmpd.conf”

  4. Create a script “/root/bin/” like this:
    LINES=$(/bin/netstat -an | /bin/grep  -c ':443'  )
    echo $LINES
    exit $LINES


  5. Make it executable
    chmod +x /root/bin/
  6. Add an “exec” statement to the “/etc/snmp/snmpd.conf” using a free/unused OID (you can use the one in this example).
    exec /root/bin/


  7. Restart the snmpd
    rcsnmpd restart

Now you are ready to test it. Enter the following command on the Data Synchronizer Server

snmpwalk -Os -c public -v 1 localhost

You should get the number of devices, like:

extResult.1 = INTEGER: 73

Finally add a new section to your mrtg.cfg (or whatever tool you might use):

Title[]: DataSyncServer - Connected Devices
PageTop[]: <H1>DataSyncServer - Connected Devices</H1>
MaxBytes[]: 250
ShortLegend[]: %
YLegend[]: Connected Devices
Legend1[]: Connected Devices
LegendI[]: Connected
Options[]: gauge,growright,nopercent,noinfo
Unscaled[]: ymwd
