No cricket stats for directories "routers" and "switches" in cricket

[Vidar Faltinsen]

This is seen on a number of 3.9.1 installations.

The problem seems to be related to ipdevpoll as the netboxsnmpoid is not populated with the OIDs mcc needs to populate the cricket config tree.

[Morten Brekkevold (mbrekkevold)]

It appears that this happens when using pynetsnmp, but not TwistedSNMP. Due to slight differences in parsing query results from either library, the oidprofiler plugin in ipdevpoll will _not_ properly find support for any OID that requires a GET (not a GET-NEXT) operation.

A patch for this is a trivial oneliner, but a re-profiling of all devices must be initiated at each installation after patching/upgrading. This could be pushed in an upgrade by simply adding a schema change file.

The oneliner ipdevpoll/oidprofiler fix has been committed here: http://metanav.uninett.no/hg/series/3.9.x/rev/f77bdd568ed9

And the forced re-profiling will take place as soon as the schema change file in http://metanav.uninett.no/hg/series/3.9.x/rev/12246e572b98 is applied.

But it seems I still was misinformed about how pynetsnmp actually returns "non-results" and had to fix the one-liner yet again. See http://metanav.uninett.no/hg/series/3.9.x/rev/17bd7442795f for (hopefully) the final fix.

Still nok ok, try this: http://metanav.uninett.no/hg/series/3.9.x/rev/0d523b779112 *sigh*
