HP-UX Network Server Accelerator HTTP B.11.31.01.03 Release Notes (5900-0837, September 2011)

Administrative utility (nsahttp)
HP-UX NSA HTTP provides the nsahttp administrative utility. This utility displays NSA
HTTP performance statistics, lists the TCP ports registered to use NSA HTTP, and displays
other configuration and statistical information. This includes:
• The total number of TCP connection requests received for the registered NSA HTTP
ports.
• The number of HTTP cache hits, which corresponds to the number of HTTP GET
requests that NSA HTTP serviced from its cache.
• The number of HTTP cache misses, which corresponds to the number of HTTP GET
requests that NSA HTTP could not service from its cache.
• The current size of the HTTP cache in bytes.
You can also use the nsahttp utility to configure operating settings for the NSA HTTP
service, including the following items:
• TCP port number for NSA registration and deregistration
• Maximum system memory usage for the URI data cache
• Idle HTTP TCP connection timeout value
• NSA HTTP cache entry timeout
• Maximum URI data size (maximum web page size) that can be cached by the NSA
HTTP service
• HTTP access logging options
Access logging, enabled or disabled◦
◦ ASCII or binary log file format
◦ Log file location
• Statistics collection
• Debug level for event logging
You can also use nsahttp to convert binary HTTP access log files to ASCII Common
Log Format (CLF), a de facto industry standard used by many log servers.
Configuration file
The /etc/rc.config.d/nsahttpconf configuration file stores NSA HTTP
configuration information to be used at system startup time and each time NSA HTTP is
activated. NSA HTTP can be enabled or disabled automatically at system startup
depending on the setting of the NSAHTTP_ENABLE flag in the /etc/rc.config.d/
nsahttpconf file. In addition, the /etc/rc.config.d/nsahttpconf file contains
all or any NSA HTTP settings to be used in conjunction with the NSA HTTP startup script.
