I want to monitor a list of Netapp Volume. In the documentation of NetApp, i found this :

1. Poll the "dfFileSys" OID to determine the Index number for each aggregate and volume on the filer.

bash-3.2$ snmpwalk -v 1 -c public filer1 .1.3.6.1.4.1.789.1.5.4.1.2
SNMPv2-SMI::enterprises.789.1.5.4.1.2.1 = STRING: "aggr0"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.2 = STRING: "aggr0/.snapshot"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.3 = STRING: "/vol/vol0/"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.4 = STRING: "/vol/vol0/.snapshot"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.5 = STRING: "aggr1"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.6 = STRING: "aggr1/.snapshot"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.7 = STRING: "/vol/vol1/"
SNMPv2-SMI::enterprises.789.1.5.4.1.2.8 = STRING: "/vol/vol1/.snapshot"

2. Once the Index values are known, poll the "dfPerCentKBytesCapacity" OID:

bash-3.2$ snmpwalk -c public filer1 .1.3.6.1.4.1.789.1.5.4.1.6
SNMPv2-SMI::enterprises.789.1.5.4.1.6.1 = INTEGER: 71
SNMPv2-SMI::enterprises.789.1.5.4.1.6.2 = INTEGER: 15
SNMPv2-SMI::enterprises.789.1.5.4.1.6.3 = INTEGER: 4
SNMPv2-SMI::enterprises.789.1.5.4.1.6.4 = INTEGER: 0
SNMPv2-SMI::enterprises.789.1.5.4.1.6.5 = INTEGER: 2
SNMPv2-SMI::enterprises.789.1.5.4.1.6.6 = INTEGER: 2
SNMPv2-SMI::enterprises.789.1.5.4.1.6.7 = INTEGER: 31
SNMPv2-SMI::enterprises.789.1.5.4.1.6.8 = INTEGER: 0

I need to link the first value with the second. Can I make this with a sensor snmp ? Or i need to use the XML Custom EXE/Script Sensor for making that ?

Hello,

if it's the Integer-Values, you could use two SNMP Custom Sensors and then one Sensor Factory Sensor.

best regards.

I have a String in the first OID, and a Interger in the second OID.

I have make a test. I have create a sensor SNMP Custom String. In the OID I have write : "1.3.6.1.4.1.789.1.5.4.1.2"

But it doesn't work. I have "No such instance (SNMP error # 223)"

But if I test the same OID with snmputil on the server PRTG it's work. I obtain :

Variable = .iso.org.dod.internet.private.enterprises.789.1.5.4.1.2.102
Value    = String /vol/bk_brcfi_lnx_02/.snapshot

So, I don't think it's a network problem, a community problm. I am making something wrong ?

I have test with your Paessler SNMP Tester 3.2. I have found the problem I think. The OID is not a single value, but under the OID, I have a table with the value

If I test the OID : 1.3.6.1.4.1.789.1.5.4.1.2 I have SNMP error #223
If I test the OID : 1.3.6.1.4.1.789.1.5.4.1.2.2 I have Value : aggr0/.snapshot

Under the first OID I have something like that :
1.3.6.1.4.1.789.1.5.4.1.2.0 : Value 1
1.3.6.1.4.1.789.1.5.4.1.2.1 : Value 2
1.3.6.1.4.1.789.1.5.4.1.2.2 : Value 3

The idea is simple, I want every line is a channel. How can I do that ?

Only with singe Custom SNMP Sensors that request one value each and then combining them into one with the Sensor Factory.
