Fast-LTA Volumes/Silent Bricks not recognized

**CMK version:**Checkmk Pro 2.5.0p7
OS version: Debian 12

Hi there,

I already posted this in the german section but I would like to post it here too.

If I should delete one of these posts, please let me know.

We got a Fast-LTA (Version 2.67.0.7) and I would like to monitor it via snmp.

The disks, general info, uptime etc are found but what is missing are the “special things” - like Silent Bricks, Volumes…

I´m not sure if the fastlta plugin gets triggered.

Is there a way to find out if this snmp query is done with the fastlta plugin enabled?

If I do a snmpwalk this is the output of sysDescr

SNMPv2-MIB::sysDescr.0 = STRING: Linux wiarchivbrick2 6.11.7-gentoo-FAST #2 SMP PREEMPT_DYNAMIC Thu Feb 26 14:11:11 UTC 2026 x86_64

Or am I missing something?

Any help is appreciated.

Thanks

Can you share the snmpwalk?

snmpwalk -v3 -l authPriv -u -a SHA -A -x DES -X -Onqet .1.3.6.1 >/tmp/snmpwalk.txt

If it has some sensitive information, you can mask it.

Sure thing - thank you for looking into it

At the end this is the cli output

Did you used the command to generate the walk?

The walk should look like this:

1.3.6.1.4.1.8072.1.9.1.1.3.10.103.114.112.99.104.101.99.107.109.107.0.3.3.6.110.111.116.105.102.121 “none”

.1.3.6.1.4.1.8072.1.9.1.1.4.10.103.114.112.99.104.101.99.107.109.107.0.3.3.5.119.114.105.116.101 4

Maybe, if the device is already added in Checkmk, then you could also download the walk from the GUI?

Sorry - here you go:

As you use SNMPv3 and the complete enterprise tree is missing inside the snmpwalk i would say that the used account has not the correct view assigned.
You can make a test with SNMPv2 to see if the data exists and if yes you should modify the SNMPv3 view settings for the user.

For a manual test you should query the OID .1.3.6.1.4.1.27417 with your SNMPv3 user.

First of all - thank you all. I really appreciate it.

If I query the given OID I get

.1.3.6.1.4.1.27417 No Such Object available on this agent at this OID

No matter the snmp version.

I´m not sure if I can configure anything inside the Fast-LTA.

Is SNMP is the way to go with this system? Or is there a better way I don´t know of (kind of like redfish for ilo).

Maybe check the Access Control / Views settings. The community string or user you are querying with is likely restricted to a generic view (often called systemview).

Have you checked if the view permissions are restricted ? or to add access specifically to the .1.3.6.1.4.1 (enterprises) subtree.If there is a toggle for “Enable Enterprise Storage MIB Extensions” or similar vendor specific options, ensure it is turned on.

That SNMP subtree is needed:


snmp_section_fast_lta_headunit = SNMPSection(
    name="fast_lta_headunit",
    detect=all_of(
        startswith(".1.3.6.1.2.1.1.2.0", ".1.3.6.1.4.1.8072.3.2.10"),
        any_of(exists(".1.3.6.1.4.1.27417.2.1"), exists(".1.3.6.1.4.1.27417.2.1.0")),
    ),
    fetch=[
        SNMPTree(
            base=".1.3.6.1.4.1.27417.2",
            oids=["1", "2", "5"],
        )
    ],
    parse_function=parse_fast_lta_headunit,
)
