Fix Processes KeyError issues with ZenDMD

We would occasionally have problems with our Processes which resulted in a 'KeyError' error. Usually running the following commands via the zendmd command would fix these errors:

> reindex()

> commit()

However there are cases where that doesn't work.  The script listed below attempts to fix that (in a very quick and dirty way).

Based on information found in the thread: http://community.zenoss.org/message/43380  I found that we had Orphaned entries in the Process list tables.  A working entry would be listed as:

'/zport/dmd/Devices/Server/Linux/devices/server.company.com/os/processes/httpd'

where a broken entry would be listed as:

'httpd'

or

'httpd AAAAAAAA000000'

Note that the working entry has a full path  where as the broken one doesn't.

The following code will go through and remove anything without a full path.

import Globals
from Products.ZenUtils.ZenScriptBase import ZenScriptBase
from transaction import commit

dmd = ZenScriptBase(connect=True).dmd

#CHANGEME
# to get the path navigate to the problem area in your browser and
# look at the URL.  So for:
#  http://zenoss.yourcompany.com/zport/dmd/Processes/Apache/osProcessClasses/httpd
# Your path will be
#  dmd.Processes.Apache.osProcessClasses.httpd

fixpath = dmd.Processes.Apache.osProcessClasses.httpd

ind = 0

print "--- "
for i in fixpath.instances():
    thispath = i.getPrimaryId()
    if thispath.find('/zport') != 0:
        print "   Deleting: %i  %s" % (ind , thispath)
        fixpath.instances._remove(i)
    ind = ind + 1

print " ** Committing changes"

# Uncomment the line below to actually save the changes. 
# commit()
