The pCDN server creates several log files:
- server.log -- contains debugging info, access logs, and route info (gathered by ping and traceroute packets)
- squid_access.log -- contains squid-like downloading logs
Upon a pCDN server is launched, a new server.log is created. We avoid name conflicts by suffixing an integer to the filenames, e.g., server.log.3. The squid_access files support log rotations: squid_access.log is the current log file, squid_access.log.1 (the most recent) through squid_access.log.6 (the least recent) are historical logs. The pCDN server, by default, keeps 7 historical log files and creates a new log file every 24-hr.
