HSL
       Namespace HSL

DESCRIPTION
       These commands allow you to send data to a pool of servers via High
       Speed Logging. High Speed Logging was designed to be a high volume, low
       overhead logging mechanism. HSL supports logging via TCP or UDP.
       Informal testing has shown CPU and memory utilization for HSL to be
       very low (<10% CPU, almost no additional memory utilization).  For
       example, you could use these commands to:
	 * Log all HTTP requests and responses processed via the LTM by
       sending the data to a pool of remote servers.
	 * Log the SSL cipher name, version, size for each SSL session before
       restricting ciphers
	 * Log every load balancing failure (not just a member failing a
       monitor)
	 * Supplement or replace tcpdump for troubleshooting layer 7 issues
       (it can be much easier to log the decrypted content rather than
       decrypting SSL with ssldump, etc)
