cflowdmux and cflowd use syslog(3) to record
errors and runtime status information. As a convention, each syslog
message starts with a capitalized letter in brackets indicating the
priority of the message:
| code | priority | description |
[A] | LOG_ALERT | fatal errors |
[C] | LOG_CRIT | errors that need attention |
[E] | LOG_ERR | error conditions |
[I] | LOG_INFO | informational messages |
