Re: [Devmon] SNMP error noSuchName

[Johan S. <joh...@de...>]

Addition:

I get the error for all three custom OID:s on the hosts that don't work, not just the OID in my example.

Subject: [Devmon] SNMP error noSuchName

Hi.

I am creating a test for VMFS utilization in our ESX template. It consists on a client-side script that is executed by snmpd reporting volume label size and free space on three different OID:s.
It works fine if I use snmpwalk from the command-line on the devmon server, and it also works fine for 4 out of our 11 ESX hosts. One the other 7 I get the following error:

Received SNMP response with error code
  error status: noSuchName
  index 1 (OID: 1.3.6.1.4.1.6876.99999.2.3.101)
SNMPv2c_Session (remote host: "xxx.xxx.xxx.xxx" [xxx.xxx.xxx.xxx].161)
                   community: "public"
                  request ID: 339225935
                 PDU bufsize: 8000 bytes
                     timeout: 10s
                     retries: 10
                     backoff: 1)
at /usr/local/devmon/modules/dm_snmp.pm line 546

Does anyone have any idea why devmon gets this error for some of the hosts? All the hosts have the same configuration on the client side, and all of them work if I use snmpwalk.

Snmpd.conf:
dlmod cmaX /usr/lib64/libcmaX64.so
proxy -v 1 -c public udp:127.0.0.1:171 .1.3.6.1.4.1.6876
rocommunity public
exec .1.3.6.1.4.1.6876.99999.2.1 vmfslabel /usr/local/delta/vmfs_snmp.sh label
exec .1.3.6.1.4.1.6876.99999.2.2 vmfssize /usr/local/delta/vmfs_snmp.sh size
exec .1.3.6.1.4.1.6876.99999.2.3 vmfsfree /usr/local/delta/vmfs_snmp.sh free

vmfs_snmp.sh:
#!/bin/bash
OPTION=$1
VOLUMES=`ls /vmfs/volumes/ | grep -v :`

if [ $OPTION = "size" ]; then
for i in $VOLUMES;do
        VMFS=`/usr/sbin/vmkfstools -P /vmfs/volumes/$i`
        SIZE=`echo "$VMFS" | grep Capacity | awk '{print $2}'`
        echo $SIZE
done
fi
if [ $OPTION = "free" ]; then
for i in $VOLUMES;do
        VMFS=`/usr/sbin/vmkfstools -P /vmfs/volumes/$i`
        FREE=`echo "$VMFS" | grep Capacity | awk '{print $8}'`
        echo $FREE
done
fi
if [ $OPTION = "label" ]; then
for i in $VOLUMES;do
        VMFS=`/usr/sbin/vmkfstools -P /vmfs/volumes/$i`
        LABEL=`echo "$VMFS" | grep label | awk '{print $6}'`
        echo $LABEL
done
fi

Best Regards,
Johan
