Line Charts for Performance Metrics
Line charts provide a meaningful visualization of performance over time. Use line charts to represent performance data, such as array performance metrics.
Array performance data is collected from certain storage arrays:
NetApp ONTAP Cluster-Mode arrays
Isilon arrays
Array LUN performance statistics are collected for Dell Compellent, EMC VNX (CLARiiON), EMC Symmetrix, HDS Tuning Manager, HP 3PAR, IBM SVC, IBM XIV, NetApp ONTAP (Block only), NetApp Cluster-Mode and Pure Storage.
For collected array LUN performance raw data, the default retention period (504 hours or 21 days) controls the retention of the data. When the daily performance data ages out, it gets deleted.
