our customer reported that in Grafana for a few volumes no data is shown. After investigating the problem we found out that the problem occurs on all svm's which have been renamed on NetApp. These SVMs were shown in Grafana with the old and the new name, but only in the old SVM Name we can see metrics. We already tried to move all data to the new SVM name and remove the old SVM folder, but as soon as we restart the netapp-harvest manager the old folder is created and all data is shwon under the old SVM Name.
Is it possible to get the information in Grafana shown in a correct way, after SVMs had been renamed on the NetApp.
Harvest should update its instance cache every 1 hour or after restart, so normally this shouldn't happen. Can your customer run Harvest in foreground mode and check whether the output metrics contain the old or new SVM names?
