Using a stand-alone collator
If you do not want the log collation server to be a Traffic Server node, you can install and configure a stand-
alone collator (SAC) which can dedicate more of its power to collecting, processing, and writing log files.
To run a stand-alone collator:
1. Configure your Traffic Server nodes as log collation clients. Refer to To configure a Traffic Server node
to be a collation client from Traffic Manager:‚ on page 116.
2. Telnet into the HP web cache appliance and select Shell Access as described in Overview of Access
Methods‚ on page 7.
3. Copy the SAC binary from Traffic Server’s
/home/TS4/<version>/bin directory to the machine
serving as the stand-alone collator.
4. Copy the
records.config file from a Traffic Server installation to a directory on the stand-alone
collator.
