Ian,
That looks like the right idea. Its zenmodeler that you need to run
to kick of a collection. To debug your plugin do this:
zenmodeler run -d YOURBOX --collect UCDHardDiskMap
You can put break points in the code to see what's going on. It
would be nice to get the drive name (like /dev/hda). When I walk
that oid on my boxes I get nothing back. :(

Erik,
You mean something like this:
Products/DataCollector/plugins/zenoss/snmp/UCDHardDiskMap.py
----
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 :

om.id = self.prepId( om.id)
om.snmpindex = oid
rm.append(om)
return rm

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. But I can not get the harddisks added to
Hardware page of a device
automaitcally.

do. You need to write a collector plugin to get the
list of disks. There are examples of this in the $ZENHOME/Products/
DataCollector/plugins directory.
