Hi,

I have just finished migrating all my zenoss 3.x hosts to zenoss 4.2.4. (I did not upgrade, I migrated by adding servers manually and bringing templates over via zenpacks). We just tried to use a custom property for the first time and I am getting this error:

Troubleshooting Suggestions
* The URL may be incorrect.
* The parameters passed to this resource may be incorrect.
* A resource that this resource relies on may be encountering an error.
For more detailed information about the error, please refer to the error log.
If the error persists please contact the site maintainer. Thank you for your patience.

NOTE: I changed the zenoss url and username in the error for security reasons.

Anyone have any idea what I can do to fix this? I can add C properties but not set them.

How are you setting the properties?

There is a nasty issue whereby if you just set the attribute directly (whether it is a standard zProperty or a cProperty), then they end up inconsistent - see http://community.zenoss.org/message/69612#69612 http://community.zenoss.org/message/69612#69612 .

Not sure if there were significant changes between 3.x and 4.2.4 but there may well have been.  I can confirm that using setZenProperty DOES work on 4.2.x with both zProperties and cProperties.

Cheers,
Jane

Hi Jane,

I create the properties at /Device level by editing the custom schema. I set the properties at whatever level I want them set like a device or device class. We are forces to use Z properties that we do not really use like zWinUser. This sucks as the Zenoss instance I migrated from, the custom schema was messed up and i thought going to a fresh 4.2.4 would fix that.

Our Zenoss Instances are very self service for users so I would have to create some kind of script to use setZenProperty.
