Using a syslog server

The Management Node acts as a syslog server, collating the logs from itself and each Conferencing Node to produce the Pexip Infinity support log. The support log includes the administrator log.

However, you can also use a remote syslog server to collect copies of each system's logs. The advantage of this is that, should the Management Node become unavailable, logging would still continue on the syslog server.

When a remote syslog server is used, the Management Node and each of the Conferencing Nodes sends its logs directly to the syslog server using the syslog protocol. The Management Node will still continue to collate logs from all the nodes, and it is these unified logs that are shown from the Pexip Infinity Administrator interface. Note that the Management Node does not send the unified logs to the syslog server — it only sends its own logs.

The Management Node shows the support log only. If you elect to use a remote syslog server, you can choose to send it audit logs and web server logs in addition to, or instead of, the support log.

You can configure more than one remote syslog server, for example if you want to send different combinations of the support, audit and web server logs to different servers. If more than one syslog server is configured, logs will be sent to each of them.

To add, edit or delete the remote syslog servers used by Pexip Infinity, go to System > Syslog servers.

The available options are:

Option Description
Description An optional description of the syslog server.
Address The IP address or FQDN of the remote syslog server.

The port on the remote syslog server.

Default: 514.


The IP transport protocol used to communicate with the remote syslog server.

Default: UDP.

Support log Enables sending of support and administrator log entries to this syslog server.
Audit log Enables sending of Linux audit log entries to this syslog server. Some security-related certifications may require this log to be recorded.
Web server log Enables sending of web server log entries to this syslog server. This is a log of all HTTPS requests to the Management Node and Conferencing Nodes.

The following table shows the facility code used for each log type:

Facility code Log type
local0 Admin log
local2 Support log
local6 Audit log
local7 Web server log

Web server logs are provided in the Apache web server format ( with the following fields:

Format string Description
%h Remote hostname
%l Remote logname
%u Remote user
%t Time the request was received
%r Received HTTP request
%P The web server process ID
%s Response status code
%b Size of response in bytes

The time taken to serve the request in microseconds

  • HTTP Referrer
  • HTTP User-Agent
%X Connection status when response is completed
