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 aect 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 They provide historical reference to actions such as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
signicant group events.

connections.
Schedules — Displays the total number of snapshot and replication schedules.

operations might need administrator intervention. The cues are displayed for critical and warning alarms, actions, group
operations, and failback operations.
