Filtering Incoming Syslog Messages and Display by Content

You can filter syslog messages by the message content (i.e., not IP address, facility or severity).

You can filter l message content on the following two levels:

Incoming traffic: Filter is applied to received syslog messages. This filter affects both the displayed log and content written to the log files.
Log display: Filter affects only the displayed log.

You can also use regular expressions (regex) to define the message content filter. You can also use regex to match multiple lines (i.e., pattern1|pattern2).

To filter syslog messages by message content:
1. On the toolbar, click the Options icon; the Options dialog box opens.
2. Under the Content Filter group, configure the message content filters:
Incoming traffic:
i. In the 'Receive filter' field, enter the message-content filter which is applied to incoming traffic.
ii. From the 'Mode' drop-down list, select Allow to allow only traffic according to your filter, or Block to block traffic according to your filter.
Syslog Display:
i. In the 'Display filter' field, enter the message-content filter which is applied to the log display.
ii. From the 'Mode' drop-down list, select Allow to display syslog messages according to your filter, or Block to not display syslog messages according to your filter.

3. Click OK.
