[regression] SNMP missing disks in hrStorageTable

[Eric Desrochers]

[IMPACT]

It has been brought to me the following:

Some hosts have started to cause UNKNOWN return values in Nagios for checks on their disks. This is because these hosts are no longer reporting their disks as part of the SNMP table hrStorageTable (1.3.6.1.2.1.25.2.3.1 ) - only memory devices are being reported. The affected hosts that I have investigated received updates for SNMP:

Upgrade package libsnmp-base 5.7.3+dfsg-1.8ubuntu3.1 to 5.7.3+dfsg-1.8ubuntu3.2
Upgrade package libsnmp30 5.7.3+dfsg-1.8ubuntu3.1 to 5.7.3+dfsg-1.8ubuntu3.2
Upgrade package snmpd 5.7.3+dfsg-1.8ubuntu3.1 to 5.7.3+dfsg-1.8ubuntu3.2

It seems likely that this package update is the cause.

As debug info, you can see the difference between 2 nearly identical servers, one of which received the SNMP updates, and one which did not. You can see that the one without the update is returning disks in the SNMP output:

# snmpwalk -v2c -cpublic arcprsmt01 1.3.6.1.2.1.25.2.3.1.3
iso.3.6.1.2.1.25.2.3.1.3.1 = STRING: "Physical memory"

iso.3.6.1.2.1.25.2.3.1.3.258 = STRING: "/run/user/1000"

The other, which received SNMP updates, is returning only memory devices, such as swap and shmem:

# snmpwalk -v2c -cpublic arcprsmt02 1.3.6.1.2.1.25.2.3.1.3
iso.3.6.1.2.1.25.2.3.1.3.1 = STRING: "Physical memory"

iso.3.6.1.2.1.25.2.3.1.3.7 = STRING: "Cached memory"
iso.3.6.1.2.1.25.2.3.1.3.8 = STRING: "Shared memory"
iso.3.6.1.2.1.25.2.3.1.3.10 = STRING: "Swap space"

[Test Case]

* Install snmp snmpd
* Configure /etc/snmp/snmpd.conf by adding the following:
 view systemonly included .1.3.6.1.2.1.25.2.3.1.3
* Restart snmpd
* Use snmpwalk:
 ** snmpwalk -v2c -cpublic localhost 1.3.6.1.2.1.25.2.3.1.3

Expected behavior is to see the disk as follow:
"
iso.3.6.1.2.1.25.2.3.1.3.1 = STRING: "Physical memory"
iso.3.6.1.2.1.25.2.3.1.3.3 = STRING: "Virtual memory"

Status changed to 'Confirmed' because the bug affects multiple users.

We have a similar problem with the Nagios:

Need this too if you haven't included it...

[Eric Desrochers (slashd)]

Thanks Joseph for your contribution on this, good catch on the missing ().

I will build a new test package and will make it available in the next hour.

[Joseph Gooch (whitemystic)]

Docker test case attached - if you untar this, and
cd DockerTestCase
docker build .

It'll run through, download the pkg from your PPA and illustrate that OIDs above 30 are missing.

I also tested the test package, 5.7.3+dfsg-1.8ubuntu3.2+testpkg20190906b3, in a direct-mapped autofs environment that was the basis for the fix that caused this regression.

The test package does fix the original autofs "mount everything" issue and allows for snmpwalk to monitor the mounted disks as well.

I even tested it with a single autofs directory mounted and it worked with that as well.

[Joseph Gooch (whitemystic)]

Confirmed testpkg20190906b3 fixes the issue for me as well.

I imagine there will need to be a xenial backport too?

[Eric Desrochers (slashd)]

Uploaded in active devel release "Eoan". Will do the SRU (X/B/D) once it lands in -release.

Hi,

I see there is at least 26 ppl impacted by this regression according to the LP bug.

Please feel free to test the -proposed package and provide positive feedback. If we have enough feedback by Thursday, I'll do my best to have an early release.

Eric
