Configure > Subsystems > Logging > Collation

Collation Mode

Specifies the log collation mode for this Content Gateway node. You can use the log file collation feature to keep all logged information in one place. For more information about log file collation, see Collating event log files.

Select Collation Disabled to disable log collation on this Content Gateway node.

Select Be a Collation Server to configure this Content Gateway node to be the collation server.

Select Be a Collation Client to configure this Content Gateway server to be a collation client. A Content Gateway server configured as a collation client sends only the active standard log files, such as Squid, Netscape Common, and so on, to the collation server. If you select this option, enter the hostname of the collation server for your cluster in the Log Collation Server field.

Note: When logs are collated, the source of the log entry—its node of origin—is lost unless you turn on the Log collation host tagged option (described below).

Log collation consumes cluster bandwidth in sending all log entries to a single node. It can therefore affect the performance of the cluster.

If you want Content Gateway as a collation client to send custom (XML-based) log files, you must specify a LogObject in the logs_xml.config file.
Log Collation Server Specifies the hostname of the log collation server to which you want to send log files.
Log Collation Port

Specifies the port used for communication between the collation server and client. You must specify a port number in all cases, except when log collation is inactive. The default port number is 8085.

Note: Do not change the port number unless there is a conflict with another service already using the port.
Log Collation Secret Specifies the password for the log collation server and the other nodes in the cluster. This password is used to validate logging data and prevent the exchange of arbitrary information.
Log Collation Host Tagged When this option is enabled, Content Gateway adds the hostname of the node that generated the log entry to end of the entry in the collated log file.
Log Collation Orphan Space Specifies the maximum amount of space (in megabytes) allocated to the logging directory for storing orphan log files on the Content Gateway node. Content Gateway creates orphan log entries when it cannot contact the log collation server.
