Monitoring ASG from Nagios through SNMP

Hi,

anyone configured Nagios to monitor ASG (120) through SNMP?

I enabled SNMP on ASG, and tried to query with snmpwalk from my external Nagios box, and it works.

Then I tried with some snmp plugins to check disk and load but it failed.

Anyone knows some working plugins for Nagios to monitor ASG through SNMP?

Thanks.

Hi Cassolo,

I've written a simple check script which needs some more development but works for me.

You need ssh root access with key authentication from the nagios user.

#!/bin/bash



. /usr/local/nagios/libexec/utils.sh



if [ $# -lt 2 ];

then

	echo "UNKNOWN - missing Arguments."

        echo "Usage:"

        echo " $(basename $0)  "

	echo ""

	exit $STATE_UNKNOWN

fi



HOSTNAME=$1

VPNNAME=$2



PREFIX="S_REF_IpsSit"

IPSECCONFIG="/var/sec/chroot-ipsec/etc/ipsec.conf"



CONNECTIONS_CONFIGURED=$(ssh root@$HOSTNAME "grep 'conn ${PREFIX}${VPNNAME}_' $IPSECCONFIG" | wc -l)

CONNECTIONS_UP=$(ssh root@$HOSTNAME "ipsec status " | grep "${PREFIX}${VPNNAME}_" | grep "IPsec SA established" | grep "newest IPSEC" | wc -l)



if   [[ "$CONNECTIONS_CONFIGURED" -eq "0" ]]; then

	echo "UNKNOWN - VPN $VPNNAME not found!"

	exit $STATE_UNKNOWN

elif [[ "$CONNECTIONS_UP" -eq "0" ]]; then

	echo "CRITICAL - No tunnel up! ($VPNNAME)"

	exit $STATE_CRITICAL

elif [[ "$CONNECTIONS_UP" -lt "$CONNECTIONS_CONFIGURED" ]]; then

	echo "WARNING - Only $CONNECTIONSUP of $CONNECTIONS_CONFIGURED tunnels up! ($VPNNAME)"

	exit $STATE_WARNING

elif [[ "$CONNECTIONS_UP" -eq "$CONNECTIONS_CONFIGURED" ]]; then

	echo "OK - $CONNECTIONS_UP of $CONNECTIONS_CONFIGURED tunnel(s) up."

	exit $STATE_OK

else

	echo "UNKNOWN - Error testing tunnels!"

	exit $STATE_UNKNOWN

fi
