[rrd-users] Re: [OT] - Get versus Getnext

[Serge Maandag]

Is the error coming from the snmp agent or from the snmpget binary
you're using?

You can b.t.w. call a script from mrtg. Then do a snmpgetnext in your
script.

Subject: [rrd-users] [OT] - Get versus Getnext



Afternoon, all...

Apologies for the slightly off-topic post...

Using MRTG I would like to query the MSSQL mssqlSrvInfoUserConnections
OID
(.1.3.6.1.4.1.311.1.4.1.1.2.1.16)

Doing a walk / getnext on the above OID using (insert your favourite MIB
browser here) I get a reponse along with a system specific OID:

[user at host]$ snmpgetnext -v2c <hostname> <community>
.1.3.6.1.4.1.311.1.4.1.1.2.1.16
enterprises.311.1.4.1.1.2.1.17.8.72.69.65.84.95.83.81.76 = Gauge32: 43

Using the OID in the reponse, I assume that I should be able to perform
a
simple snmp get on it to get the data I require.

BUT:

[user at host]$ snmpget -v2c <hostname> <community>
.1.3.6.1.4.1.311.1.4.1.1.2.1.16.8.72.69.65.84.95.83.81.76
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: enterprises.311.1.4.1.1.2.1.16.8.72.69.65.84.95.83.81.76


Two questions: 

1. Does anyone have any idea as to why this is the case?

2. Can I make MRTG do a getnext instead of a get? (I think I know that
this
is a no).

I have tried both SNMPv1 and v2c.
I have tried appending .0 .1 .2 etc to the end of the OID.

Please help!!

Many thanks in advance for any insight anyone may give me.

Kind Regards,

SM
