Symptom
SAIE Application traffic charts are not displayed in Multi tenant cluster.
Conditions
if a cEDGE router is disconnected from vManage for some time. and there are more than1000 files accumulated on router in /tmp/json/app-agg directory, vManage will not able to delete these files after the device is reconnected to vManage. Then disk space for dpi stats on this device will be used up and there will be no more new dpi records generated on router.
Workaround
user can selectively backup the files under /tmp/json/app-agg directory, and leave fewer files in /tmp/json/app-agg directory, vManage can continue collect data properly.
Further Problem Description
vManage collect statistics from devices every 30 mins by default, and the timer is configurable. In each collecting cycle, vManage will pull data from device and then delete files. the defect is that vManage can't delete files from device properly, if there are large number of files in a single directory, and finally disk space for stats will be used up on device.
