Base History Reports

Trending and historical reports for TCP/IP requires, at a minimum, reporting on workload and response time.  Workload for TCP/IP may be measured as sessions or bytes either for an application or for a particular client.  The reports provided by NPM/IP provide a baseline measurement of your network activity.

The Base History Reports provide three categories of reporting:

Workload

Shows the workload creating the most demand on your system.  Available reports are:

  • Top Clients (Bytes)
  • Bytes by Application
  • Sessions by Application

Usage

Shows the absolute usage per interval chosen for applications and clients. For an application, the report indicates which clients (addresses) were using that application. For a client, the report indicates which applications the client was using.  Available reports are:

  • Application Usage Details
  • Client Usage Details

Response Time

Provides information on the average response times for a particular address, the network, and in terms of network performance relative to service goals.

  • Response Time for Network
  • Response Time for Resource
  • Service Level for Response Time

Workload Reports

The Workload Reports show the workload creating the most demand on your system.  All reports are available in both graphical and tabular formats.

A brief description of each Workload Report follows:

Top Clients (Bytes)

Clients sending the most bytes over the selected time period.

Bytes by Application

Number of bytes sent and received per application

Sessions by Application

Number of sessions per application.

 


Top Clients (Bytes)

The Top Clients report shows the clients who are sending the most bytes over the selected time period (interval) for the particular clients chosen.  The clients are the remote IP addresses using an application within the TCP/IP address space selected.  The Total Bytes represents the sum of the bytes sent and received.

Graphical Report

Data may be viewed by the week, day, hour, or year. Use Options/Change Graph to select the type of graph, background, colors, legends, and many other parameters.  Charts are available in two or three dimensions.

Tabular Report

The tabular report format provides the same basic information as the graphical report format.

The fields on the Top Clients (Bytes) tabular report are:

Name/Address

Remote IP address of any socket-attached OLTP application using the selected TCP/IP address space.

Time

Date of session.

Number of Bytes

Sum of bytes sent and received.

 


Bytes by Application

The Bytes by Application report shows the number of bytes sent and received per application as well as the total number of bytes for the interval chosen.  The number of bytes is the sum of the bytes sent and received. Applications include Telnet, e-mail, or any other socket-attached OLTP applications using the selected TCP/IP address space. 

Graphical Report

Data may be viewed by the week, day, hour, or year.  Use the Change Graph option to select the type of graph, background, colors, legends, and many other parameters.  Charts are available in two or three dimensions.

The X-axis lists the application while the Y-axis shows the total number of bytes sent and received.  Refer to the legend to determine the exact data for each value.  Rest the mouse on a column to see the detail for that value.

Usage Reports

The Usage Reports provide information on the absolute usage per interval chosen for applications and clients. For an application, the report indicates which clients (addresses) were using that application. For a client, the report indicates which applications the client was using. 

A brief description of each Usage Report follows:

Application Usage Details

The client (IP address) using the application for the interval selected, including the number of bytes in and out

Client Usage Details

The TCP/IP applications used by a particular client (IP address) for the interval selected, including the number of bytes in and out

 

Application Usage Details

Application Usage Details shows the client (IP address) using the application for the interval selected.  The number of bytes in and out is also shown.  A client may have more than one session.  Applications include Telnet, e-mail, or any other socket-attached OLTP applications using the selected TCP/IP address space.  To use this report, the application name must be specified as a parameter to the selection.

Tabular Report Format

This report is available only in a tabular report format.  Each entry represents one session.

The fields on the Application Usage Details tabular report are:

Address

IP address of client using the application during the interval selected.

Name

DNS name of client using the application during the interval selected.  This parameter is only available if the Use DNS name option is used.  If no DNS name is available, the IP address is shown.

Bytes In

Number of bytes in to the application during the session.

Bytes Out

Number of bytes out to the client during the session.

 


Client Usage Details

Client Usage Details shows the TCP/IP applications used by a particular client (IP address) for the interval selected.  The number of bytes in and out is also shown.  A client may have more than one session.  Applications include Telnet, e-mail, or any other socket-attached OLTP applications using the selected TCP/IP address space.  To use this report, the IP address must be specified as a parameter to the selection.

Tabular Report Format

This report is available only in a tabular report format.  Each entry represents the total count.  That is, there may have been more than one session during that interval.

Response Time Reports

The Response Time reports provide information on the average response times for the test done by the host and on the varying number of bytes sent in the tests set up through the Master workstation.  The reports show the times per packet sent for the addresses that are being monitored.  Reports are available in graphic and tabular formats.

A brief description of each report follows:

Response Time for Network

Response time by the number of bytes sent through the customized test for the devices monitored for the interval chosen.  This is the aggregate time over the network for the customized tests.

Response Time for Resource

Maximum, minimum, and average response times for the devices monitored for the interval chosen.

Service Level for Response Time

Shows the critical resources that have exceeded the user -defined service goals for response time.  Service goals are set in the Response Time for Resource(s).

 


Response Time for Network

The Response Time for Network report shows the response time by the number of bytes sent through the customized test for all devices monitored for the interval chosen.  The packet lengths and frequency are set in the Master.

Graphical Report

Data may be viewed by day, by week, or by hour. Use the Change Graph option to select the type of graph, background, colors, legends, and many other parameters.  Charts are available in two or three dimensions.

Figure 85.  Response Time for Network

Reviewing the Response Time for Network report helps determine if there are bottlenecks in the network caused by fragmentation.  For example, a certain network component may be set up for a maximum segment size of 512 Kbytes.  Packets less than 512 are not segmented; packets greater than 512 Kbytes are segmented.  There may be a significant difference in response time between those packets which are less than 512 and those greater than 512.


Tabular Report

The tabular report format provides the same basic information as the graphical report format.

Each record of information consists of three lines on the Response Time for Network tabular report.  The three lines must be used together to provide the following information:

Packet Size
