Hope this helps!

FYI: I found that the Primary server has all the information if you do an snmpbulkwalk -v2c -c public IP-of-server1 or 2 .1 >FILENAME The size of the file is very large for the online server compared to the offline server. I did the command above for both servers and then did a diff of the 2 files. I then looked for the Virtual IP address using: grep -I "<virtual-IP>" *

If you find a better alternative, please let me know.

I currently use the Juniper .cgi web page in the Xymon bb-hosts line to verify that there is a response. Both return the identical screen so you cannot tell which is online from this testing.

This is what I am looking to do and then I want to toggle RED/YELLOW/GREEN icons on the same Xymon display line. The only device that seems to have the virtual IP address in the MIB is the live device.

STRING=public # Set to your RO string #----------------------------------

Loop through each Juniper SSL-VPN

#---------------------------------- for IP in IP-of-server1 IP-of-server2 do #-------------------------------------- # Get the sysName - either IVE1 or IVE2 #-------------------------------------- NAME=/usr/bin/snmpget -v2c -c $STRING $IP SNMPv2-MIB::sysName.0 2>&1 | \ awk -F'=' '{print $2}' | \ awk -F':' '{print $2}'

    #-------------------------------------------------------------
    # Get the ipAdEntAddr - <Virtual-IP> or 'No Such Instance ...'
    #-------------------------------------------------------------
    VIRT=`/usr/bin/snmpget -v2c -c $STRING $IP

IP-MIB::ipAdEntAddr.<Virtual-IP> 2>&1 |
awk -F'=' '{print $2}' |
awk -F':' '{print $2}'` if [ "$VIRT" = "" ]; then VIRT=" off-line" fi echo -e "IP: $IP NAME: $NAME Virtual IP: $VIRT" done

Hello Tom,

I am using a MIB check to verify that a device (in a set of HA devices) is the current one using the virtual IP address.

I can tell from my scripting that the device has switched to the other

of the HA pair.

(A Juniper SSL-VPN pair).

I will be using NET-SNMP on the XYMON server to gather the info using a crontab script.

Which MIB variable (OID) can be used to determine which device is the one using the virtual IP address?
