Net-SNMP disk io mib is totally broken on every machine I have ever
tried :(

Hi Zenoss users,
I'm hoping to get Linux disk IO graphed with SNMP just like for the
Windows systems.
I add a performacne template of HardDisk in /Device/Server/Linux
just like in /Device/Server/Windows
diskIONRead .1.3.6.1.4.1.2021.13.15.1.1.3
diskIONWrite .1.3.6.1.4.1.2021.13.15.1.1.4
diskIOReads .1.3.6.1.4.1.2021.13.15.1.1.5
diskIOWrites .1.3.6.1.4.1.2021.13.15.1.1.6
And Graphs:
IO Bytes: diskIONRead_diskIONRead, diskIONWrite_diskIONWrite
IO Counts: diskIOReads_diskIOReads, diskIOWrites_diskIOWrites
Nothing show up, for the snmp index of the disks must be modeled.
I copied the InformantHardDiskMap.py to UCDHardDiskMap.py in
Products/DataCollector/plugins/zenoss/snmp/
and make some modification, which look like:
----
from CollectorPlugin import SnmpPlugin, GetTableMap
#from string import find
class UCDHardDiskMap(SnmpPlugin):
"""Map SNMP UCD-DISKIO-MIB sub-agent to HardDisk"""
maptype = "HardDiskMap"
modname = "Products.ZenModel.HardDisk"
relname = "harddisks"
compname = "hw"
snmpGetTableMaps = (
GetTableMap('diskIOEntry',
'.1.3.6.1.4.1.2021.13.15.1.1',
{
'.2': 'id',
}
),
)
def process(self, device, results, log):
return
"""collect snmp information from this device"""
log.info('processing UCD hard disks for device %s' %
device.id)
getdata, tabledata = results
dtable = tabledata.get("diskIOEntry")
if not dtable: return
rm = self.relMap()
for oid, disk in dtable.items():
om = self.objectMap(disk)
#if om.id == "_Total": continue
#if find(om.id,"hd") != 0 and find(om.id ,"sd") != 0 :
continue
om.id = self.prepId(om.id)
om.snmpindex = oid
rm.append(om)
return rm

If I have Zenoss-Plugins installed in the same system, this plugin
won't load.
After I removed Zenoss-Plugins, the plugin loaed without problem.
But nothing show in the target device's Hardware tab.
I managed to manually created a hda disk in ZMI. And I get the hda
in Hardware tab.
After I restarted zenperfsnmp from /About, the graph shows nan. And
some time later,
I see the graphic.
How can I make the modeler add the harddisks automatically? I can't
add do them all
manually?
I know very little about Python/Zope.
Thanks!
Ian
