This article provides steps to configure the fuser timeout in the Virtualization Manager Appliance.
All VMan versions
If you are seeing config jobs which finish after an hour without having collected all datastore information, increasing the above fuser value and the je.rjmgr.maxDuration.s parameters is necessary. There is a tradeoff however. If the parameters are increased, the jobs will finish with complete data set, but they will finish later. This means that alerts will also be evaluated later.
