SNMP and Snapshots

itacticam — Thu, 05 Jun 2025 07:27:30 GMT

Hi guys,

Does anyone know if it is possible to use snmp (custom traps) to get the amount of snapshots per volume?

Greetings,

Hans Oele

You should be able to get this info using the following found in the traps.dat

slVNumber snmp.1.3.6.1.4.1.789.1.5.5.2.1.8.1

####explanation found in netapp.mib####

    slVNumber                       OBJECT-TYPE
    SYNTAX                          Integer32
        MAX-ACCESS                      read-only
        STATUS                          current
    DESCRIPTION
            "Number of snapshots for this volume / aggregate."

Hi Allen,

Thanks for you're response.

I tried it and I know that I'm sort of a noob on the snmp part so excuse me for that.

When I execute the snmp get on our netapp I get the following

SNMP>
SNMP> o 1.3.6.1.4.1.789.1.5.8.1.2.10

SNMP> g 1.3.6.1.4.1.789.1.5.5.2.1.8.10
iso.org.dod.internet.private.enterprises.netapp.netapp1.filesys.snapshot.slVTable.slVEntry.slVNumber.1 = (null)
SNMP> g 1.3.6.1.4.1.789.1.5.5.2.1.8.10
iso.org.dod.internet.private.enterprises.netapp.netapp1.filesys.snapshot.slVTable.slVEntry.slVNumber.10 = (null)
SNMP>

Don't know if you can give me a hint or a link to some extra info maybe.

The reason I want this is to let the monitoring tools report an event as soon as there are 250 snapshots on a volume. So that in case of a failure to remove snapshots or any other reason the support team can take any actions to solve the issue. Now the only thing I have are event messages as soon as it is to late.

Kind regards,

Hans

P.s. the o 1.3.6.1.4.1.789.1.5.8.1.2.10 is a lun with snapshots on it.

Hi Hans,

Here is a kb from the NOW site that explains the setup of the snmp traps.
