Using Cisco CallManager Trace Gathering Tool for Diagnostic Traces


The Cisco CallManager Trace Gathering Tool provides the means to quickly and easily collect diagnostic trace files for Cisco CallManager system activities from all Cisco CallManager servers in a cluster.

If you are responsible for monitoring and managing a Cisco CallManager system, you sometimes have to extract, merge, and sort individual trace files to facilitate problem solving. This task may require manual logins to several different Cisco CallManager servers in a single cluster. The Cisco CallManager Trace Gathering Tool uses a web-browser-based interface to help automate this process.

The Cisco CallManager Trace Gathering Tool also provides for selection of specific types of traces from Cisco CallManager systems. When gathering and filtering diagnostics, you get a merged text file that is sorted in chronological order. If you have large files, which sometimes result from an extensive query, you can compress and extract them for easier handling.


Note Cisco CallManager Trace Gathering Tool is automatically installed with Cisco CallManager.

Audience

This document is written for developers and network administrators responsible for setting up and managing Cisco CallManager systems. Readers need extensive knowledge of telephony and IP networking technology to use this tool.

Web Browsing Requirements

The Cisco CallManager installation for the Cisco CallManager Trace Gathering Tool creates a world wide web virtual directory named TraceTool. This virtual directory allows you to run the tool from a web browser by entering a URL. The application requires Internet Explorer 4.01 Service Pack 2 or later. Netscape 4.5 is also supported.

Although the Cisco CallManager Trace Gathering Tool has a look and feel common to the Cisco CallManager Administration pages, it is independent of the Cisco CallManager Administration interface.

Security

When you use Cisco CallManager Trace Gathering Tool, you are authenticated as a user through the Internet Information Server (IIS) authentication method of the web virtual directory. The Cisco CallManager administration pages use the same authentication method.

User Interface

The user interface shown in Figure 1 minimizes your involvement by simplifying the trace selection process. You can specify the trace you need without worrying about where the files are located, or what the filenames are, on each Cisco CallManager server.

With the Cisco CallManager Trace Gathering Tool user interface, you can specify collection criteria such as

server names within a cluster

time range

trace type

search string pattern.

The interface currently supports an OR search, allowing you to cite multiple parameters when searching. Cisco CallManager Trace Gathering Tool validates each of your selections, then executes your request.

Using Cisco CallManager Trace Gathering Tool

Use the following procedures to collect diagnostic traces using the Cisco CallManager Trace Gathering Tool:

Defining Your Query

Viewing or Downloading Your Data

Compressing and Extracting Your Data

Printing Your Results

Defining Your Query

To define your query, perform the following procedure.

Procedure:


Step 1 Open a web browser. See the "Web Browsing Requirements" section, for information on the correct web browser support.

Step 2 Use the host name of one of your Cisco CallManager servers in a URL to start the Cisco CallManager Trace Gathering Tool.

http://<server_name>/TraceTool/traceform.asp

where <server_name> is the Cisco CallManager server name.

Step 3 Enter the user name and password.

Step 4 If the local URL is entered correctly, the graphical user interface appears, as shown in Figure 1.

Step 5 Using the Add or Select All buttons, select one or more servers from which you want to gather trace.

Step 6 Using the Date and Time fields, enter the time span for which you want trace data.

Step 7 Select the Type(s) of trace you want returned. Three formats are available:

CCM—Cisco CallManager

SDL—Signal Distribution Layer

TFTP—Trivial File Transfer Protocol

Step 8 Enter a search query using one or more terms.


Note The search process is case sensitive.


Step 9 Select the Submit Form button and wait for the system to process your query.



Tips Examining the logs with a general introductory query will give you information for narrowing your search. Event ID numbers are useful, and they are defined within the log files.


Viewing or Downloading Your Data

To view or download your data, perform the following procedure.

Procedure:


Step 1 Start by following all steps listed in the "Defining Your Query" section.

Step 2 Wait for the request completion notification as shown in Figure 2. This notification allows you to access your data.

Figure 2 Trace Gathering Tool Processing

Step 3 To view the result of your query, select here.

Step 4 To download the result of your query, right click here as shown in Figure 3 and save it to a local drive.

a. Save Target As if you are using Internet Explorer.

b. Save Link As if you are using Netscape.

Figure 3 Downloading the Result of Your Query

Compressing and Extracting Your Data

Cisco CallManager Trace Gathering Tool identifies and collects trace data, then provides a link to the result. If the result of the query is over 2 MB in size, the system recognizes the size (Figure 4) and offers you use of the compression and extraction utilities for easier data handling

Figure 4 Compressing Results

.

The compression and extraction features of Cisco CallManager Trace Gathering Tool use tools from the Windows 2000 Resource Kit, which is shipped with Cisco CallManager 3.0.

Once you download the compressed result to your local file system, you can use the Windows 2000 extraction utility for displaying the results of your search query on your local computer.


Tips If you want to retrieve as much data as possible, check all of the trace data type boxes, but do not enter a search term before submitting the form.


Displaying Large Results Files on a Cisco CallManager Server

To display large results files on a Cisco CallManager server, perform the following procedure.

Procedure:


Step 1 Start by following all of the steps listed in the "Defining Your Query" section.

Step 2 You may get a request completion notification (Figure 4) notifying you that your search result exceeds 2 MB.

Step 3 To view a file that is larger than 2 MB on a Cisco CallManager server, select here.

Step 4 To compress the large data file, select Compress Result to save space on the server.

Step 5 To extract the compressed data file from the server for display, select Extract Result.

Figure 5 Expanding Results

Saving Large Results Files to A Local System

To save large results files to a local system, perform the following procedure.

Procedure:


Step 1 Start by following all of the steps listed in the "Defining Your Query" section.

Step 2 Wait for the request completion notification (Figure 4), which notifies you that your search result exceeds 2 MB.

Step 3 To save a large file and download to another system, select Compress Result, then save the file to your local file system by selecting here.

Step 4 To extract the compressed file from your local file system, bring up a command window and use the command line utility extract.exe as follows:

C:\extract <filename>


Printing Your Results

To print your results, perform the following procedure.

Procedure:


Step 1 View or download the results of your query as described in the "Viewing or Downloading Your Data" section.

Step 2 Use your web browser's Page Setup and Print Preview features to format your query results.

Step 3 Print your query results. Figure 6 shows an example of a printed query.

Performance Impact

The Cisco CallManager Trace Gathering Tool runs as a low-priority task so that it does not disrupt higher priority Cisco CallManager functions. However, the tool should be used judiciously, because it can be resource intensive.

If possible, run this tool only when the Cisco CallManager system is not busy. Because traces are being collected and merged into an output file, the tool continuously accesses the disk.


Note It is assumed that the Cisco CallManager system has enough disk space for the temporary output files. Currently, there is no user interface is provided to clean up these temporary files, but the tool does automatically recycle them.


Memory impact on the Cisco CallManager system is minimal, as long as only a few concurrent users run this tool at any given time.
