[mrtg] Sql user connections

[Dijk, Sebastian van]

As i am getting a bit more familiar with the "snmp troubles" i am now
trying to monitor our "SQL user connections" :)
 
With GETIF i found that i need to use ".1.3.6.1.4.1.311.1.4.1.1.2.1.16"
to monitor the amount of "sql user connections'.
 
When i enter this ID in snmp walk i get a bit weird result (you should
only expect the value that's been read)
 
D:\snmpwalk>snmpwalk ipadres community .1.3.6.1.4.1.311.1.4.1.1.2.1.17
--> ENTER
.iso.3.6.1.4.1.311.1.4.1.1.2.1.17.12.83.81.76.95.83.69.82.86.69.82.48.49
= Gauge
: 111
 
So it does work, it measures 111 SQL user connections.
However what is that strange ID i get on the 2nd line ?
If i use that one with snmp walk i get no result.
 
I tried to use the "good ID" in MRTG : 
 
Target[SQL_USERS_SQL01]:
.1.3.6.1.4.1.311.1.4.1.1.2.1.16&.1.3.6.1.4.1.311.1.4.1.1.2.1.16:read_vec
ozo at 192.168.10.30 
 
Then i started it :
D:\BEHEER\MRTG\mrtg-2.11.1\bin>perl mrtg test.txt
This gave me this result : 
 
SNMP Error:
