In uCMDB 10 & 11 versions, the failed discovery jobs listed cannot be exported in one single excel sheet if it is greater that 100. Mean to say if errors are greater than 100, say 2000, we cannot export all the errors in one single excel sheet in one time. Maximum of 100 entries can be exported at any point of time.
It will be really good if you implement this in future release because if we have say 2000 entries of failed discovery, we need to pull out 20 individual reports instead of one..
Please refer to case - SD02482364 for more information.
Indeed, we cope with the same problem. When a lot of warnings and errors are present it is really hard to analyze the messages - because this "chunking" .Export to excel should be in place and export all rows. PS :Moreover I am afraid that in CMS UI it will be even worse job...
