log_hosts.config

To record HTTP transactions for different origin servers in separate log files, you must list each origin server hostname in the log_hosts.config file. In addition, you must enable the HTTP Host Log Splitting option. You should use the same log_hosts.config file on every Traffic Server node in your cluster. After you modify the log_hosts.config file, run the traffic_line -x command to apply the changes. When you apply the changes to a node in a cluster, Traffic Server automatically applies the changes to all other nodes in the cluster.

Format

Each line in the log_hosts.config file has the following format:

hostname

where hostname is the hostname of the origin server.

Hint

You can specify keywords in the log_hosts.config file to record all transactions from origin servers with the specified keyword in their names in a separate log file. See the example below.

Examples

The following example configures Traffic Server to create separate log files containing all HTTP transactions for the origin servers webserver1, webserver2, and webserver3:

webserver1
webserver2
webserver3

The following example records all HTTP transactions from origin servers that contain sports in their names. For example: sports.yahoo.com and www.foxsports.com in a log file called squid-sport.log (the Squid format is enabled):

sports
