View Response-Time Graphs
Note: This feature is not available on PacketShaper ISP, PacketShaper 1200, or PacketShaper 1400 Lite models.
To view response-time graphs of a class:
1. Click the monitor tab on the navigation
bar. The Monitor Traffic window appears.
2. Choose Response Time on the Monitor drop-down list.. The Monitor Response Time window appears.

3. For the class you want to graph, click the  icon. Three graphs appear in the window. show screen

Description |
| Transaction Delay |
A timeline of a traffic class' average response times. Three colored
lines track the total, network, and server delays, so you can determine
the source of any significant delays. The horizontal line represents
the Total Delay Threshold as a reference point to determine the quality
of the response times. |
| Service Level Compliance |
The percentage of good transactions. This graph shows two lines,
one representing the required percentage of good transactions and
the other representing the actual percentage of good transactions.
The first line is always flat. The second line varies, depending on
performance. |
| Transaction Delay Distribution |
The number of transactions whose total delay falls into each of
the 14 transaction-time buckets; the median delay is indicated on
the bottom of the graph. Each time slot contains the number of transactions
that are delayed with the specified number of seconds. |
4. Click More details at the bottom of the
window to display a report containing three additional graphs.

Description |
| Network Delay Distribution |
The number of transactions whose network delay falls into each
of the 14 transaction-time buckets; the median delay is indicated
on the bottom of the graph. |
| Server Delay Distribution |
The number of transactions whose server delay falls into each of
the 14 transaction-time buckets; the median delay is indicated on
the bottom of the graph. |
| Packet Round-Trip Time |
The history of a transaction’s round-trip time (RTT). RTT
is 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). A transaction involving
a large amount of data requires the data to be divided into multiple
packets. Whereas a transaction’s network delay reflects the total
transit time for all required packets, the RTT reflects the time for
a single packet to make its way from client to server and another
packet to make the return trip. |

the Time Period.
