Application Response Time

Cisco PVM enables you to troubleshoot performance problems by collecting Application Response Time (ART) data from NAMs and correlating the data to clients and servers. Administrators set up ART data collection definition using defined domains of NAM data sources that have little or no interaction with one another. ART Groups enable you to quickly find relevant NAMs and identify and troubleshoot performance problems.

All Cisco PVM users can generate the following ART reports:

•Network Flight Time—enables you to find out whether the network or the server is the cause for delayed responses

•Server Response Time—shows the response times for each server in an ART Group

•Client/Server Investigation—shows the response times for each client/server pair of a data source in an ART group by client IP

•Client/Server Response Time—enables you to check whether a response time problem exists between two sites by showing the response times for each client/server pair in an ART Group created specifically for client NAMs.

This chapter contains the following sections:

•The ART GUI

•Understanding ART Groups

•ART Reports

•Network Flight Time

•Server Response Time

•Client/Server Investigation

•Client/Server Response Time

The ART GUI

The ART GUI (Figure 5-1) allows all users to generate Server Response Time, Network Flight Time, Client/Server Investigation, and Client/Server Response Time reports based on ART Groups set up by Cisco PVM Administrators. You can also view report schedules and archives for each report type.

Administrators can set up ART Groups that define aggregation of ART data by data source.

Figure 5-1 ART GUI

Understanding ART Groups

An ART Group is defined as a set of data sources for one or more NAMs attached to client and server machines. All ART reports in Cisco PVM are run based on ART Groups created by Administrators.

Before creating an ART Group, you should decide:

•Which client, server, or client/server pair you want to monitor and

•The data source(s) from the NAMs closest to each client and server that you want to see in the reports.

Cisco PVM displays all ART Groups that have been defined in the system in tabular form on the ART > Setup window; groups can be added, edited, or deleted from this window.

ART data collection is functionally separate from all other statistics, where users create Data Source Groups to view data under Monitor and Reports. In the case of ART, you must create ART Groups if you want to view ART reports. Additionally, ART functionality includes only reporting capability and not monitoring; ART reports function as snapshots of response-time activity.

This section contains the following topics:

•Group Creation and Considerations

•ART Data Collection

•Viewing the List of ART Groups

•Adding an ART Group

•Editing an ART Group

•Deleting an ART Group

Note The functions discussed in this section apply to Cisco PVM Administrators only.

Group Creation and Considerations

Creating ART Groups allows Administrators the convenience of being able to quickly select client and server NAMs for monitoring and reporting by limiting the number of relevant NAMs available for selection. The ART Group creation process involves the following steps:

1. Enter a group name and description.

2. Select the NAM to populate the list of all available data sources.

3. Select the NAM data source(s) for which you want to collect ART data.

4. Repeat steps 2 and 3 to select more NAMs if desired.

5. Specify the Report Interval (in seconds), which specifies the ART-related polling interval for the NAM device.

6. Specify the Max Entries value, which represents the maximum number of data points the NAM device can store in that polling interval for ART-related data.

7. Specify the Maximum Response Time (in milliseconds).

Caution If the same data source is added to more than one ART Group, the three parameter values (Report Interval, Max Entries, and Maximum Response Time) must be the same as the other ART Group(s) containing the same data sources to maintain consistency. If you attempt to enter values for a data source that differ between the ART Groups in which it appears, the system will return an error message indicating that the new ART Group cannot be saved because the values you entered do not match those in the previously created ART Group.

Factors you should consider include the following:

•Unless you have a specific need to collect ART data over the long term, ART groups should normally be created for short-term monitoring and troubleshooting of problematic areas of the network to avoid storage of unnecessary or excessive data.

•ART report data will be more meaningful and easier to interpret if you limit the number of data source types you attach to each NAM within an ART Group.

•To generate Network Flight Time reports, it is necessary to include both server and client NAMs in a single ART Group.

•To ensure easier ART Group selection when generating reports, give careful consideration to the name you assign to each group; the drop-down group selection lists in report parameters shows only the group name and not the description.

Note Although Cisco PVM collects data from both server and client NAMs, the system cannot identify which NAM is closest to each server or client. Therefore, when you generate ART reports, the system lets you decide which NAMs you want to see. If you have a significant number of NAMs, remember that you can name individual NAMs to give them a more meaningful designation when they appear in Cisco PVM drop-down lists. See Editing NAMs, page 2-8 for more information on changing NAM names.

ART Data Collection

Cisco PVM automatically begins collecting traffic statistics for a NAM as soon as it is added to the system. However, collection of data into the ART database occurs only if ART Groups have been set up in Cisco PVM.

It is important to note that even if the NAM has been configured to collect ART statistics, you will not be able to view the data in ART reports until ART Groups have been set up in Cisco PVM. Cisco PVM is able to recognize whether ART data collection has been disabled for a specific data source, and will raise an alert since data collection has ceased. To restart collection in this case:

•Delete and re-apply the data source to an ART Group or,

•Check whether the data source's attached device needs to be enabled in Cisco PVM Setup or has another problem that requires troubleshooting.

If a data source is part of any ART Group, then PVM will enable data collection for that source. To disable data collection entirely in Cisco PVM, the data source must be removed from all ART Groups.

Note Historical ART information associated with a data source is maintained in the database even if the data source is removed from an ART Group.

Viewing the List of ART Groups

The ART setup GUI provides a list of all the ART Groups currently configured in the system, including names and descriptions. The list can be filtered by group name, as well as the NAMs and data sources included in the group.

Step 1 Click ART in the Cisco PVM dashboard or click Setup in the ART navigation menu if you are already in the ART GUI.

The list of ART groups displays in the ART Window (see Figure 5-2).

c. Click Add. The new data source appears at the bottom of the Selected Device Data Source(s) list.

d. (Optional) If desired, repeat steps (a) through (c) to add other data sources.

Step 9 Click OK.

The ART window appears with the message, "ART Group [name] was updated."

Note If a NAM device or NAM data source is deleted from the system, the Edit ART Group window will not display the deleted NAMs or data sources as part of an ART Group originally containing the deleted elements.

Deleting an ART Group

To delete multiple ART Groups at the same time from the ART Groups window, complete the following steps:

Step 1 Click ART on the Cisco PVM dashboard, or click Setup if you are already in the ART GUI.

The ART window appears the current list of ART Groups.

Step 2 Find the ART Group you want to edit by:

•Reviewing the displayed ART Groups list.

•Clicking column headers to sort the list.

•Filtering the list.

•Using the pagination links on the right side of the window header.

Step 3 Check the box(es) next to the ART Group(s) you want to delete.

The Delete button is enabled on the ART window.

Step 4 Click Delete. The system prompts you to confirm the deletion.

Step 5 Click OK in the confirmation dialog.

The ART window refreshes without the deleted group(s) and the message, "The selected ART Group was deleted."

ART Reports

Reports you generate under the Cisco PVM ART tab can display aggregated Application Response Time data from the last 24 hours, or from the previous days, weeks, months, or years, depending on when the NAM began collecting ART data.

Historical ART data associated with a data source is maintained in the database even if that data source is removed from an ART Group. Cisco PVM records the time the data source was removed, but maintains the original data source in ART report search criteria that belong to a time interval during which that data source still existed in the ART Group.

This section contains the following topics:

•Report Parameters

•Report Types

•Network Flight Time

•Server Response Time

•Client/Server Investigation

•Client/Server Response Time

Report Parameters

The ART Reports GUI contains report parameter setup options that differ in certain respects from the Monitor and Reports functions in Cisco PVM. When you click Reports in the ART navigation menu, the ART window header appears with the report parameters pane defaulted to Network Flight Time (see Figure 5-10).

Report Types

The response time reports allow selection of the Report Type on the report parameters window, which allows you to choose the format of the data display:

•Tabular—Displays the number of packets and bytes collected for the specified report. The data displayed is the total number of packets and bytes collected since collection began, unless you select a specific time period.

•TopN—Displays the data collected for the top most active data streams for the selected ART Group in the report being generated. The data is displayed as a column-type chart, with green link boxes for the various metrics by which the TopN chart can be viewed. The value of N is configurable under Setup > Preferences.

Note This option is not available for Network Flight Time reports.

Network Flight Time

The Network Flight Time (NFT) report enables you to discover whether the network or the server is causing delayed response times. Network Flight Time is calculated as the difference of the response times on the NAM closer to the client versus the NAM closer to the server.

The response time collected by the NAM at the client location represents the total average round trip delay time of the request and response. The response time collected by the NAM at the server location represents the average server latency time. Cisco PVM can therefore calculate the average network flight time for the request between the client and the server:

Network Flight Time = Total Round Trip Time - Server Latency Time

Note You must be familiar enough with your network setup to be able to determine which NAMs reside closest to servers and clients.

To generate an NFT report, enter the following parameters:

•Reporting period—The number of previous days (defaulted to today), weeks, months, or years, or a specific date range that defaults to the previous 30 minutes

•Client IP—Required field with no set default value

•ART Group—Provides a list of available groups for selection upon search

•Server IP—Provides a list of available NAMs for selection upon search

•Client-side NAMs—Provides a list of NAMS based on the selected client IP, ART group, server IP, and reporting period upon search

•Server-side NAMs—Provides a list of NAMs for selection excluding those selected as client-side NAMs upon search

•Scheduling—Provides the option to run a report immediately, at a later time, or recurrently
