I have FAS8020 with Ontap 8.3.2.
I try to set up snmp to monitor volume free space.
I download mib version 2.4.2 and can see it undr netapp-0 for volumeFull and volumeNearlyFull with OID 184.108.40.206.4.1.789.0.82 and 85.
However, I got "No data available in this sub-tree" by snmpwalk.
Actually I got this message for all the objects under netapp-0.
As for objects under netapp1, i have no issue at all.
Does anyone know what's going on?
The .220.127.116.11.4.1.789.0 OID tree is essentially a list of traps that OnTAP can send out (assuming you have a traphost defined).
You cannot access it using snmpget/snmpwalk etc.
Your monitoring system should be able to extract the information out of the MIB file so that it can decode any traps that it receives from the filer.
If you want to do some 'active' monitoring of the volumes , have a look at the data under .18.104.22.168.4.1.722.214.171.124.1.
You can also use the data to track space utilisation over time if you want.
Hope this helps.
According to your suggestion, I have tried the OID but still cannot get it.
The message show as below.
[root@zabbix-corp2 zabbix]# snmpget -v 2c -c xxxxx 172.16.60.23 .126.96.36.199.4.1.7188.8.131.52.1.5
SNMPv2-SMI::enterprises.7184.108.40.206.1.5 = No Such Instance currently exists at this OID
I am using the zabbix to monitor my system.
You are getting that error because you are using snmpget instead of snmpwalk.
Try running 'snmpwalk -v2c -c xxxxxx 172.16.60.23 .220.127.116.11.4.1.718.104.22.168.1'
But, before you do that, you need to download and install the NetApp MIB file for the version of OnTAP you are running.
Otherwise your SNMP client won't be able to translate the data received from the filer.
Just go to the NetApp support site and search for 'mib file download'.
