About Monitoring
You can review comprehensive data about your array groups. Monitoring your PS Series array groups provides data that enables you
to assess the health of your storage environment to quickly identify hardware and software problems.
Monitoring provides valuable data about the time and action of users on the system, protecting against security intrusions. Using Dell
EqualLogic performance monitoring tools, you can gather information about group performance based on latency, IOPS, I/O rate, I/O
size, and other data. With this data, you can quickly be informed of hardware, capacity, and performance-related problems, allowing
you to make corrections and minimize downtime.
Monitored data is invaluable when accessing your customer support account and reporting problems directly to technical support.
• Events — Displays events to track operations and also to detect and solve problems before they aect performance or data
availability. Audit messages are syslog events about administrator actions. They provide historical reference to actions such as
logging in, logging out, creating a volume, setting up replication, and other events. In addition, you can use SNMP traps to track
signicant group events.
• Statistics — Displays information about the current and recent administrative sessions and the number of active iSCSI
connections.
• Schedules — Displays the total number of snapshot and replication schedules.
• NAS Schedules — Displays NAS snapshot, replication, and data reduction schedules.
• Replication — Displays active replication activity (including inbound and outbound replication), and replication history.
• NAS Replication — Displays active NAS replication activity (including inbound and outbound replica containers), and NAS
replication history.
• Sync Rep — Displays information about SyncRep volumes.
• Alarms and Operations — Displays a visual cue to alarm conditions in the group, as well as in-progress operations. Some
operations might need administrator intervention. The cues are displayed for critical and warning alarms, actions, group
operations, and failback operations.
Tools That Monitor and Manage Storage Performance
Dell EqualLogic provides the following tools for monitoring and managing the storage performance of your group:
• Group Manager GUI
• Group Manager Performance Monitor, available from the Group Manager GUI
• SAN Headquarters, which enables you to monitor multiple PS Series groups from a single GUI
About Using Group Manager to Monitor Performance Data
The Group Manager GUI provides dozens of views that provide comprehensive data about your array groups. From the Group
Manager GUI, you can monitor the following data:
• Events
• Administrative sessions
• iSCSI connections
• Snapshot schedules
