Background

This is Kells Kearney's ZenPack.community.mib_utils ZenPack, updated to work with Zenoss 3. It has been tested with Zenoss 3.1 and with Firefox 3.6.13 and 4.0b12. No functional enhancements have been made and the testing emphasis has been on the MIB Browser functionality, rather than any other features.

To make this ZenPack work with Zenoss 3.2 or Zenoss 4.2 you need to reverse some standard code "updates":

I have just upgraded from 4.2.3 to 4.2.4 without de-installing the fixed MIB Browser ZenPack. The manual changes of the 4 files have been overwritten (though my backup .orig files are still present). Re-replacing these 4 files again makes it work again with 4.2.4. Read the README on GitHub for Zenoss 5 details.


I believe I have a way to make this ZenPack work with 3.2.x. Basically you revert 4 Core files back to the 3.1 level of code. Zenoss development kindly provided a patch to do this but I have found that their 3.2.1 patch didn't work on my system - I think it was built from a slightly later build. I will provide their patches and also document here what actually needs to change in case the patches don't work for you either. The manual patch also worked for me on Core 4.2. See the documentation page for this ZenPack for the oldmib_3.2.1.patch and oldmib.patch.

oldmib.patch worked for me on a 3.2.0 system. oldmib_3.2.1.patch did NOT work for me on a 3.2.1 system (neither did the oldmib.patch)

If you want to try the patches, copy them to $ZENHOME and change directory there. Run:

patch -p 0 < oldmib.patch

to apply a patch. To undo it and restore to original, use:

patch -R -p 0 < oldmib.patch


You will need to completely restart Zenoss and make sure your browser cache is cleared out.

If you need to make manual changes, this is what you need (all directories under $ZENHOME):

Products/ZenUI3/browser/backcompat.py

==================

Comment out the lines at the end defining MibClass

+#def MibClass(ob): +# id = '/'.join(ob.getPhysicalPath()) +# return '/zport/dmd/mibs#mibtree:' + id

If there are also similar lines for MibNode and MibNotification, comment them out too

Products/ZenUI3/browser/navigation.zcml

====================

Around line 247, change the url line to be url="/zport/dmd/Mibs/mibOrganizerOverview" - url="/zport/dmd/mibs" + url="/zport/dmd/Mibs/mibOrganizerOverview"

Note carefully the case sensitivity on mibs / Mibs


Products/ZenUI3/browser/backcompat.zcml

====================

Around line 355 comment out lines for the adapter for "Products.ZenModel.MibOrganizer.MibOrganizer" If adapter stanzas also exist for MibNode, MibNotification and MibModule, comment them out too


Products/ZenModel/skins/zenmodel/viewMibModule.pt

=============================

Change the template in the first line to be <tal:block metal:use-macro="here/page_macros/old-new">


-<tal:block metal:use-macro="here/templates/macros/page2"> +<tal:block metal:use-macro="here/page_macros/old-new">


This should not be tried on a production system but if anyone can help verify this on a development system, I would be grateful.


I am going to petition Zenoss to restore this code to the 3.1 level as I do not believe that the 3.2 code adds any benefit and it breaks this ZenPack. My understanding is that Zenoss Core 4.?? is NOT planning to incorporate mib browsing as part of the base product.
