Error description
Observation of performance metrics for an SVC storage device show a noticeable change in the performance graph where it spikes up and down in an exagerated sawtooth pattern for a period of time and then goes back to the expected metric tracking. During these bursts of sawtooth activity, it is found that the collection interval for the storage device alternates between 5 minutes (expected) and 10 minutes (unexpected). The storage devices that are configured as the backend of the SVC are also monitored but are not providing the expected performance metrics at times and this is unexpectedly affecting the SVC and its metrics.
