As a request comes in, it is denoted in the scoreboard. The scoreboard itself is basically a way to keep track of each incoming, waiting, and completing connections. These connections are broken down into the following types:
- “_” Waiting for Connection
- “S” Starting up
- “R” Reading Request
- “W” Sending Reply
- “K” Keepalive (read)
- “D” DNS Lookup
- “C” Closing connection
- “L” Logging
- “G” Gracefully finishing
- “I” Idle cleanup of worker
- “.” Open slot with no current process
Here is an example of the apache scoreboard in WHM:
