Performance Profiles

A Performance Profile specifies marginal and critical threshold values for performance metrics appropriate to each component type. You must set up performance profiles if you want ReportCenter to generate performance exceptions. Daily threshold crossings generate exceptions that can be monitored on the various reports in the ReportCenter Report Server.

The Performance Profiles dialog box lists all the currently defined performance profiles set up for your system. From this dialog box, you can examine the properties for each performance profile, add new profiles, delete obsolete profiles, rename existing profiles, and change the properties of existing performance profiles.

To view, create or modify Performance Profiles use the ReportCenter Administrator Console program.

To view performance profile information, click Show > Performance Profiles. To add or change performance profiles, click Define > Performance Profiles. The Performance Profiles dialog appears.

To create a new profile click Add.

To make changes click Modify, the Modify Performance Profile appears.

PacketShaper Thresholds

Select PacketShaper to modify device-related thresholds

Set the following thresholds to meet your requirements:

Marginal and Critical Threshold Values — Type the Marginal and Critical threshold values for each of the following performance metrics, as necessary. Exceptions will be generated when daily marginal or critical threshold values are crossed. ReportCenter notes one exception for each day in which a particular threshold is crossed at least once by a specific component. Multiple threshold crossing events in the same day for a specific component are counted as a single exception.

Inbound Throughput (bps) — The average inbound data rate for the period.

Peak Inbound Throughput (bps) — The highest recorded inbound data rate for the period.

Inbound Utilization % — Average inbound throughput of the component relative to the maximum inbound throughput of the component during the report period.

Peak Inbound Utilization % — The maximum percentage of total throughput for the component during the report period.

Inbound Network Efficiency % — The ratio of inbound bytes that were not retransmissions to total inbound bytes during the period.

Minimum Inbound Network Efficiency % — The lowest sampled value for the ratio of inbound bytes that were not retransmissions to total inbound bytes.

Outbound Throughput (bps) — The average outbound data rate for the period.

Peak Outbound Throughput (bps) — The highest recorded outbound data rate for the period.

Outbound Utilization % — Average outbound throughput of the component relative to the maximum outbound throughput of the component during the report period.

Peak Outbound Utilization % — The maximum percentage of total throughput for the component during the report period.

Outbound Network Efficiency % — The ratio of outbound bytes that were not retransmissions to total outbound bytes during the period.

Minimum Outbound Network Efficiency % — The lowest sampled value for the ratio of outbound bytes that were not retransmissions to total outbound bytes.

Utilization % — Average throughput of the component in both directions relative to the maximum throughput of the component for both directions during the report period.

Peak Utilization % — The maximum percentage of total throughput in both directions for the component during the report period.

Network Efficiency % — The ratio of bytes in both directions that were not retransmissions to total bytes in both directions during the period.

Minimum Network Efficiency % — The lowest sampled value for the ratio of bytes in both directions that were not retransmissions to total bytes in both directions.

Traffic Class Thresholds

Select Traffic Class to modify application-related thresholds.

Marginal and Critical Threshold Values — Type the Marginal and Critical threshold values for each of the following performance metrics, as necessary. Exceptions will be generated when marginal or critical threshold values are crossed, one per day per component.

Average Throughput (bps) — The average data rate for the period.

Peak Throughput (bps) — The highest recorded data rate for the period.

Network Efficiency % — The ratio of bytes that were not retransmissions to total bytes.

Good Transaction % — The percentage of transactions that do not require retransmission.

Normalized Network Delay (ms) — The transaction delay in the network, normalized by transaction size.

Network Delay (ms) — The average number of milliseconds packets spent in transit.

Server Delay (ms) — The average number of milliseconds required for servers to process requests. The time starts when the server has received all required request packets and ends when the server issues the first packet of the response.

Total Delay (ms) — Average number of milliseconds to complete transactions; includes network delay and server delay.

Round Trip Time (ms) — The average number of milliseconds spent in transit when a client and server exchange the SYN (synchronize sequence numbers flag) and its corresponding ACK (acknowledge flag).

Packet Exchange Time (PET) — Packet Exchange Time is the time observed for two hosts to exchange a packet.

TCP Connections — The number of TCP connections started.
