This document describes the dumplog utility, which allows you to view a specified log file associated with a Cisco Intelligent Contact Management (ICM) process.

Readers of this document should be knowledgeable of the following:

  • Troubleshooting software issues

  • Cisco ICM

Components Used

The information in this document is based on the software and hardware versions below.

  • Cisco ICM

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

What Does the Dumplog Utility Do?

The dumplog utility converts binary log files written by Cisco ICM processes into readable format. Once converted, the log file contents can be referenced to gain insight into ICM operation. Typically, dumplog is used as a troubleshooting tool, but it can be educational as well.

The dumplog utility can be invoked from either a command prompt directly on the ICM server, or from a Telnet session to the ICM server.

Note: The following examples assume that ICM is installed on the C drive. If the ICM is installed on a different drive, then directory locations will change accordingly.

For server naming conventions used in this document please see ICM Server Naming Conventions.

How to Get to the Logfile Directory

The path to the Cisco ICM logfile directory is <root>\icr\customer instance name\node name.

Where <root> is the drive where ICM is installed, for example, C, D, or E.

For example, if you consider that Cisco ICM Call Router is installed on the C drive, the logfile directory on geocscortra would be located at: c:\icm\csco\rtra\logfiles.

Note: The following can be used as a shortcut to the logfiles directory: c:\>cdlog <cust_inst> <ICM_Node>.


Below are command line options for the dumplog utility. They can help you solve problems by allowing you to view Cisco ICM log files within a specific time period. The time period is definable using the /bd, /bt, /ed, and /et switches. The user can also search for a specific string to further isolate and troubleshoot questionable ICM behavior.

This information can also be found in the "Cisco Intelligent Call Router Administrator Guide."

dumplog [ProcessName(s)] [/dir Dirs] [/if InputFile] [/o] 
  [/of OutputFile]
  [/c] [/bd BeginDate(mm/dd/yyyy)] [/bt BeginTime(hh:mm:ss)]
  [/ed EndDate(mm/dd/yyyy)] [/et EndTime(hh:mm:ss)] [/hr HoursBack]
  [/all] [/last] [/prev] [bin] [/m MatchString] [/x ExcludeString] [/ms] [/debug] 
  [/help] [?]
Parameter Descriptions

ProcessName(s) The command dumps the current day log for this process, unless you specify different dates or times with other arguments.
[/dir Dirs] Directory specifies the location of the log files for any processes listed on the command line after the /dir switch. If no /dir switch is used, the current directory is used by default.
[/if] InputFile specifies a specific .ems file to dump. The /if token is optional. If you specify an input file, the /bd, /bt, /ed, /et, /hr, and /all arguments are ignored.
/o Writes output to a text file in the \logfiles directory. The filename is formed by adding the .txt suffix to the specified process prefix or input file name (without the .ems suffix). The file is written to the current directory.
/of OutputFile specifies an output text file; for example, c:\temp\mylog.txt.
/c Specifies continuous output. The command does not exit after reaching the end of the log. Instead, it waits and writes any further entries that appear in the log.
/bd BeginDate(mm/dd/yyyy) specifies the begin date. If used with /bt, this specifies a range of dates. Otherwise, dumplog dumps events for only the specified date.
/bt BeginTime(hh:mm:ss) specifies the begin time. Use with /et to specify a range of time.
/ed EndDate(mm/dd/yyyy) specifies the end date. Use with /bd to specify a range of days.
/et EndTime(hh:mm:ss) specifies the end time. Use with /bt to specify a range of time.
/hr HoursBack specifies a number of hours back from the current time.
/all Displays all information from the specified process log files.
/last Displays information from the most recent log file for the process.
/prev Displays information from the next to last log file for the process.
/m MatchString displays only events that contain a match for the specified string.
/x ExcludeString displays only events that do not contain a match for the specified string.
[/ms] Displays milliseconds in time stamps.
[/mc] Use multiple colors when dumping merged logs. Each process is given a different color. You must specify either a ProcessPrefix or an InputFile. If you give only a ProcessPrefix value (for example, rtr, nm, or lgr), dumplog displays the current day log for that process by default.

Note: To view redirected log files using Microsoft Notepad, save the log file to a text file (using the dumplog /of argument), and open the text file from the command prompt by issuing the: notepad filename command.

Sample Dumplog Usage

The following example shows the dumping of the rtr log file on the router from the beginning of April 29, 1999 until April 30, 1999. It outputs to a log file called rtr.txt. The file rtr.txt can now be viewed using a standard text editor such as Notepad.

c:\icm\csco\rtra\logfiles dumplog rtr /bd 04/29/1999 /ed 04/30/1999 /o

The following command dumps the pgag log file from a peripheral gateway (PG) beginning at the last time a new log file was open for output.

c:\icm\csco\rtra\logfiles dumplog pgag /last
