Error description
The customer is using Storage Insights to monitor a SpecV device with a 5-minute Performance Monitoring (PM) interval. In approximately every 40 minutes, there is an occurrence where Storage Insights "misses" a Performance Monitor data point for that particular device. This results in temporary values of "Device is not providing valid performance data" for Data Collection and Performance Monitoring Status in the Block Storage Systems table. However, this issue is momentary as the next Storage Insights performance monitoring collection from the device is successful. This problem has the potential to impact all SpecV devices being monitored by a data collector. However, devices monitored by Call Home with Cloud services remain unaffected. To verify the problem, navigate to the Resource tab, right-click on the selected device, and choose "View performance." Compare the Performance Monitoring (PM) interval by choosing 'Toggle chart/table' located in the upper right corner. During the reproduction of the issue, observed the missing samples in a scenario where the storage device had a 2-minute interval, and Storage Insights was configured with a 5-minute interval.
Local fix
To address the issue, modify the performance stats interval on the device to either 5 minutes or 1 minute using the startstats command. The preferred and default interval for Storage Insights is 5 minutes. Utilize the following command to set the interval on the device. startstats -interval 5
