Pavel,
Take a look a the plugins in $ZENHOME/Products/DataCollector/plugins/
zenoss/snmp/HRSWInstalledMap.py for and example. Here are some high
level points though:
Define the type map you will be using the target class type the
relationship name and the component name. here we are populating the
relation dev.os.software with Sofware objects. This is most likely
what you want.
maptype = "YourSoftwareMap"
modname = "Products.ZenModel.Software"
relname = "software"
compname = "os"
To get a table returned with named columns defined a tuple of
GetTableMap objects at the class level.
snmpGetTableMaps = (
GetTableMap('swTableOid', '.1.3.6.1.2.1.25.6.3.1',
{'.1': 'snmpindex',
'.2': 'setProductKey',
#'.4': 'type',
'.5': 'setInstallDate',
}
),
)
In the method process you will be building a list of ObjectMaps that
go into a RelMap. One confusing thing in this method is the way a
software instance is stored. Most of the data (ie the name) goes
into the class object. This is found by the zenoss backend using the
setProductKey method. This key is used to find the software product
for the instance you have collected (the product is under a
manufacturer in the /Manufacturers root). If none is found a new one
is created in the /Unknown manufacturer.

I need to write custom data collector plugin.
I found that doc on wiki si in fact just skeleton. Can you at least
provide some high-level steps? I just need to query the system for
software installed (i.e. patches, versions etc) which are populated
over enterprise mib. Therefore need to use custom one.
I tried to undestand code, but maybe providing some guidance with
reference to code will help.
Thx. p.
