Trouble with Sentry CDUs and Zenoss 3.2

I have several Sentry CDUs that we're trying to get some meaningful power usage statistics from. I have a fresh install of Zenoss 3.2, and I've tried installing the Sentry CDU egg, but have had little success with it. I do notice that it's not supported by Zenoss 3.2 though.

 

I've set up a monitoring template with several data sources and appropriate OIDs to monitor. When I test the tmplate via the "test" button in the "edit data source" dialog for the template, I'm returned values that look sane and are what I expect. My devices are bound to the correct template - the template I created shows up under the appropriate device's Monitoring Templates. I see the graphs I created, but they are not being populated with data.

 

Can someone provide some insight? I've perused these forums, but haven't found any advice that helps.

 

Thanks Much!

Louie

    Re: Trouble with Sentry CDUs and Zenoss 3.2

    I can think of a couple of things here.

    There is a patch to base 3.2 to fix a bug with leading dots on an SNMP data source. You need to get 3 patches to go on top of base 3.2 - see the item here community/zca/blog/2011/09/22/zca-update-for-september-22-2011--zenoss-32-warning-zenpacks .

     

    If that doesn't fix it, then you may have problems with instance of the OID.  The Test button is great but it doesn't do exactly the same as the zenperfsnmp daemon and the test button can mask OID instance problems - basically the test does an snmpwalk and the zenperfsnmp does an exact SNMPGET.  If the patches don't fix you, could you post the OIDs that you are using??

     

    Basically, if the OID is a scalar (single) value, like sysUpTime, then your data source needs a .0 on the end.  If the SNMP data is a table then you don't put the instance - it will be substituted automatically for each row in the table (eg. getting interface info).

     

    Cheers,

    Jane
