Overview

You can filter the Syslog entries that are shown in the Analyzer by SIP Message type and/or IP Address of the SBC 1000/2000 Peer device. You can also include Module errors and control the format of the Syslog file.

 

Excluding SIP Messages from the Log

You can exclude messages of specified SIP types (i.e., OPTIONS, INVITE, etc..) from the messages shown in the Message Pane when a log is parsed. You can also exclude the responses to those messages on a Call ID basis.

To exclude messages of a specified type:

  • Enter a comma separated list of those message types in the Excluded SIP Messages text box.
  • If you wish to exclude the responses to the excluded SIP Messages, select the Match Call-ID for exclusion check box.

Excluding Messages from Peer Devices

You can exclude messages from specific SIP Peer devices. .

To exclude messages from peer devices:

  • Enter a comma separated list of the IP addresses of the devices in the Excluded IP Addresses text box.

Viewing Module Errors

You can view module errors (SIP, CCC, and MSC) in individual tabs in the Lower Display Pane if you have selected one or more items inthe Module Errors group of the Configuration dialog.

To view module errors:

  1. Select the appropriate options (SIP, CCC, MSC) are selected in the Module Errors group.
  2. Select the appropriate logging levels in the Error levels group.
  3. Save your selections by clicking OK.
  4. Open the log file.
  5. Click the appropriate tab at the top of the Lower Display Pane.

External Syslog Formatting

External Syslog Formatting is used to format syslog files so that they can be parsed by LX correctly. External syslog servers usually append 4 words to each line of the syslog file. Those could be the host name and a timestamp. The Line Prefix Split Count setting must be set prior to opening the external syslog file with LX. This feature is explained in more details in section LX 1.0 - Working with Syslogs from External Servers.

Some syslog servers, such as syslogd, use hexadecimal line breaks. Since the SIP messages are received in a single line, the syslog server adds either <010><010> or <013><010> as line breaks for each line of the SIP message. This prevents proper parsing of the SIP messages. The RegexPattern - Line Breaks setting allows you to specify a Regex pattern to be replaced as a line break.

Syslog Server Settings

LX can write logs to a disk instead of the screen and is more efficient when capturing logs for an extended period of time.

Log Rotate Interval

Specifies the interval between log rotations. If no interval is specified, log rotation defaults to 10 minutes.

Log Destination

The destination for logs written to disk. This field is active only when Enabled (Disk Save) is selected.

Enabled (Disk Save)

Enables saving the logs to disk.
