Hi there.

Monitoring a osx "server" with observium. To get it to see the NF shares I added this to snmpd.conf:

skipNFSInHostResources 0 storageUseNFS 2

This worked and I now see the shares. The large NAS is reported with wrong sizes though. Expected is this:

df -ah |grep midskog filmddn:/ddnnas0/midskog 958Ti 193Ti 765Ti 21% 7479476 692520524 1% /Volumes/midskog

Reported in observium is: Size: 208GB Used: 915GB Free: -707GB

I actually think this could be an net-snmp bug in OSX but I'm not sure. When I snmpwalk locally I see this for that particular mount:

HOST-RESOURCES-MIB::hrStorageType.61 = OID: HOST-RESOURCES-TYPES::hrStorageFixedDisk HOST-RESOURCES-MIB::hrStorageDescr.61 = STRING: /Volumes/midskog HOST-RESOURCES-MIB::hrStorageAllocationUnits.61 = INTEGER: 512 Bytes HOST-RESOURCES-MIB::hrStorageSize.61 = INTEGER: 436207616 HOST-RESOURCES-MIB::hrStorageUsed.61 = INTEGER: 1920024576

Any one that had similar issues and found a solution?

Next issue is that i try to monitor a process called 'nsd'. I have added it so snmpd.conf and when i walk the device locally I see it:

filmserver01:snmp filmserver01$ snmpwalk -c public -v2c localhost UCD-SNMP-MIB::prTable UCD-SNMP-MIB::prIndex.1 = INTEGER: 1 UCD-SNMP-MIB::prNames.1 = STRING: nsd UCD-SNMP-MIB::prMin.1 = INTEGER: 0 UCD-SNMP-MIB::prMax.1 = INTEGER: 1 UCD-SNMP-MIB::prCount.1 = INTEGER: 1 UCD-SNMP-MIB::prErrorFlag.1 = INTEGER: noError(0) UCD-SNMP-MIB::prErrMessage.1 = STRING: UCD-SNMP-MIB::prErrFix.1 = INTEGER: noError(0) UCD-SNMP-MIB::prErrFixCmd.1 = STRING:

But observium doesn't pick it up. Is this something that isn't supported or am I missing something?

Cheers and thanks.

This is due to bugs with the snmp daemon.

You need to run a more recent version.

New subject: Monitor OSX system. Problem with reported size for NFS share and monitor processes

We don't have any support for net-snmp's process table.

The disk space issue is very, very well known, and requires a fairly new version of net-snmp to fix.

Hi Adam

Gotcha. And no plans for process monitoring?

Mmm. Upgraded now but now it ignores my settings in snmpd.conf so instead it reports loads of disks as networkDisks and hence skip them in observium.

hrStorageType.59 = hrStorageNetworkDisk

hrStorageType.60 = hrStorageFixedDisk

hrStorageType.61 = hrStorageNetworkDisk

hrStorageType.62 = hrStorageNetworkDisk

Looking at the debug I can see them being skipped to guess the system now reports them badly.

Hello

Short answer... Don't want to mess with the GPFS cluster and server.

The snmpd config has an option to treat NFS disks as fixedDisks but actually seems like a but in current release that makes it fail. Saw the disks with 5.6 but then with wrong size. In 5.7.3 the disks are ignored.

Investigating and think it's an old bug that's reintroduced. Will try to apply that patch and rebuild it.

Cheers

We don't have any support for net-snmp's process table.

The disk space issue is very, very well known, and requires a fairly new version of net-snmp to fix.

This is due to bugs with the snmp daemon.

You need to run a more recent version.

I actually think this could be an net-snmp bug in OSX but I'm not sure. When I snmpwalk locally I see this for that particular mount:

Any one that had similar issues and found a solution?

Next issue is that i try to monitor a process called 'nsd'. I have added it so snmpd.conf and when i walk the device locally I see it:

But observium doesn't pick it up. Is this something that isn't supported or am I missing something?

Cheers and thanks.

New subject: Monitor OSX system. Problem with reported size for NFS share and monitor processes

You should be aware that collecting data from network file systems in the poller can cause some nasty issues if the filesystems become unavailable.

In general as Tom said, these should be monitored from the server.

Hello

Short answer... Don't want to mess with the GPFS cluster and server.

The snmpd config has an option to treat NFS disks as fixedDisks but actually seems like a but in current release that makes it fail. Saw the disks with 5.6 but then with wrong size. In 5.7.3 the disks are ignored.

Investigating and think it's an old bug that's reintroduced. Will try to apply that patch and rebuild it.

Cheers

They are network disks, aren't they? So they're doing it right.

But Observium is configured by default to ignore network disks (monitor them on the server, not on 20 clients simultaneously!) so you might have to fix that :-)

Gotcha. And no plans for process monitoring?

Mmm. Upgraded now but now it ignores my settings in snmpd.conf so instead it reports loads of disks as networkDisks and hence skip them in observium.

hrStorageType.59 = hrStorageNetworkDisk

hrStorageType.60 = hrStorageFixedDisk

hrStorageType.61 = hrStorageNetworkDisk

hrStorageType.62 = hrStorageNetworkDisk

Looking at the debug I can see them being skipped to guess the system now reports them badly.

SQL[SELECT * FROM `storage` WHERE `device_id` = '24' AND `storage_index` = '60' AND `storage_mib` = 'host-resources-mib']

31 -> host-resources-mib

33 -> host-resources-mib

Will sleep on it and attack it tomorrow again. =)

Adam,

I don't know if you saw my post from late last year:

With RH 6.5 onwards I've found that putting

realStorageUnits 0

in snmpd.conf appears to provide a fix for file systems at least as large as 36TB.

It's noted in bug BZ#654384 here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/htm...

That gives correct disk space reporting with net-snmp 1:5.5, and looks as if it was incorporated into the svn net-snmp trunk in 2011, look at the message dated 2011-02-18 14:49:05 in this post to a net-snmp mailing list:

http://sourceforge.net/p/net-snmp/mailman/message/26988027/

It may be worth amending the FAQ ?
