Syslog

Syslog records UNIX/Linux system-wide events. Network Performance Monitor can accept Syslog messages from specific devices running Syslog or from all devices, depending on the selected options.

It is not unusual for WhatsUp Gold to receive Syslog messages from a Syslog server daemon (syslogd) running on a non-UNIX operating system (OS). For example, some environments will deploy such a device as a centralized/dedicated Syslog host. Syslog uses standard C libraries and can be ported to run on operating systems other than UNIX.

Each log message record contains the following data columns:

Date. Date and time for the event message.
Source. Device where the message originated.
Syslog Type. Type of syslog message received.
Details. Information contained in the syslog message.

Fetch and filter log data

Choose device. Choose one or more host devices.

Choose time constraints. Choose specific windows for log data, or choose Last Polled for the latest.

Filter and reduce by row and by column. Select rows based on specific column values, remove columns, and remove noise and chaff from the table.

Note: If the receiving port is not on the list of firewall exceptions, messages may not be receivable and as a result will not be added to Syslog. Please ensure that the syslog receiving port is on the firewall's list of exceptions.

Tip: If you experience page load delays for device or system passive monitor reports (SNMP Trap, Syslog, and Windows Event Log), this may be caused by too many records to display for this report time range. Change the time range or reduce the Maximum Passive Monitor Records setting to display fewer records. Reducing the maximum number of passive monitor records improves Network Performance Monitor report display performance. For more information, see Managing server options.

Group by this field.	Group table into collapsible rows wherever the current column contains identical data ("field") values.
Filters.	Provide a keyword and use wildcards to view only rows that contain the keyword for the selected column or view. Most column and log view filters provide the following wildcard matching: Match either zero characters or any one character ('?'). Example: `198.51.100.2?` (Matches tokens with IP address ending with 2, or 20-29.) Match either zero, any one, or many characters (*''*). Example:* `Stop` (Matches log strings containing Stop, Stopped, Stopping*, and so on.)
