My Zenoss public endpoint was working fine until i installed a zenpack "ZenPacks.community.deviceAdvDetail-2.9.0.egg". I am now trying to remove the zenpack and it but its failing. Could you please provide some directions on this?


Below is the error while trying to list the zenpack.

unless the developer has updated that recently that zenpack is super old.  most likely is it adds support for a status threshold that most likely is using old rrd based commands.

I know that zp pretty well along with hp/dell community zenpacks.  those also have some issues with some old code styles, i know of at least two things that break in later versions of Z4.x and 5/6.

we have newer versions internally developed that do similar things but i used to use those zenpacks and had them running and updated for years.

Doug, any chance you are willing to share your internally built versions?  I know I'd like to use the EQL zenpack, but it requires the Advance Device Details Zenpack and as this thread has already spoken to that zenpack has not be updated to be compatible.
