HSLAB HTTP Monitor is a handy real-time performance monitoring and statistics analysis software application for Apache servers, which are used ubiquitously in the web hosting industry. Basically, with HSLAB monitoring system administrators always know who is currently connected (via connection tree), server operations distribution, amount of bandwidth being consumed, number of server requests per unit of time and other important server parameters.

HSLAB HTTP Monitor shows all virtual servers being hosted, statistics for them and what files or documents are being accessed. There is an option to create a profile for each virtual server - a handy feature indeed. HSLAB HTTP Monitor shows what operations are being executed:

Waiting for Connection, Starting up, Reading Request; Sending Reply; Keepalive (read); DNS Lookup; Closing connection; Logging; Gracefully finishing; Idle cleanup of worker; Open slot with no current process.
