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:

  1. “_” Waiting for Connection
  2. “S” Starting up
  3. “R” Reading Request
  4. “W” Sending Reply
  5. “K” Keepalive (read)
  6. “D” DNS Lookup
  7. “C” Closing connection
  8. “L” Logging
  9. “G” Gracefully finishing
  10. “I” Idle cleanup of worker
  11. “.” Open slot with no current process

Here is an example of the apache scoreboard in WHM:
