EMC Isilon Array Performance Metrics
Isilon performance data is collected from SNMP MIB statistics. For example, collected data includes such metrics as cluster, node, protocols (CIFS, SMB, FTP, HTTP), and disk performance.
Isilon array performance statistics are captured for the following intervals:
• raw data, as collected
• hourly
• daily
The following metrics are collected for EMC Isilon arrays.
• EMC Isilon Array Performance
• EMC Isilon Disk Performance
• EMC Isilon Node Performance
• EMC Isilon OneFS Performance
• EMC Isilon Protocol Performance
