adding charts, generating reports, or adding dashboard KPI records.

Data export: Data for both the active and obsolete data replication tunnels can be exported

Threshold monitoring
This section describes threshold monitoring in HP P6000 Performance Advisor.
Overview
The threshold monitoring feature enables you to monitor performance and view the threshold
summary of the following performance objects against threshold levels you configure for specific
counters:
•
Storage Systems
•
Virtual Disk
•
Virtual Disk Group
•
Physical Disk Group
•
Data Replication Group
•
Controller
•
Host Connection
•
Host Port
Threshold monitoring is supported for a specific set of counters for each of the supported objects.
For more information, see
“Supported counters” (page 167) .
The major and minor threshold levels are the first and second levels of performance indicators. To
configure these settings:
1.
For an object type, select the counters for which you want to monitor the performance data,
and specify the minor and major threshold levels for the counter.
2. Select the threshold level at which you want to receive alerts (optional).
The threshold summary is available at the storage system, object type, and performance object
level, and only for objects whose counters are selected for threshold monitoring. The threshold
summary value indicates the percentage of time the performance object remained within, at, or
above the configured threshold levels.
When a storage system or performance object is added for threshold monitoring, the threshold for
throughput (Req/s), data transfer rate (MB/s), or Queue Depth is based on the sum of both the
controllers value. But, the latency is considered as the maximum of controller A and controller B,
except for counters related to host ports. Also, the threshold summary for an object type shows
only the current set of threshold-monitored counters for objects. Similarly, for a threshold monitored
storage system or performance object, its threshold summary shows only the current set of
threshold-monitored counters. If you change the threshold monitoring settings, the new settings take
effect the next collection cycle.
