Td pagi abis nambah paket baru SARG di router Ubuntu 8.04 Hardy Heron LTS wnet punya tmn, pdhal smua seting dah pd bener cmn pas wkt generate koq malah gini:
sarg -l /var/log/squid/access.log

access.log di SQUID

TCP_HIT ::: A valid copy of the requested object was in the cache.
TCP_MISS ::: The requested object was not in the cache.
TCP_REFRESH_HIT ::: The requested object was cached but STALE. The IMS query for the object resulted in "304 not modified".
TCP_REFRESH_FAIL_HIT ::: The requested object was cached but STALE. The IMS query failed and the stale object was delivered.
TCP_REFRESH_MISS ::: The requested object was cached but STALE. The IMS query returned the new content.
TCP_CLIENT_REFRESH_MISS ::: The client issued a "no-cache" pragma, or some analogous cache control command along with the request. Thus, the cache has to refetch the object.
TCP_IMS_HIT ::: The client issued an IMS request for an object which was in the cache and fresh.
TCP_SWAPFAIL_MISS ::: The object was believed to be in the cache, but could not be accessed.
TCP_NEGATIVE_HIT ::: Request for a negatively cached object, e.g. "404 not found", for which the cache believes to know that it is inaccessible. Also refer to the explainations for negative_ttl in your squid.conf file.
TCP_MEM_HIT ::: A valid copy of the requested object was in the cache and it was in memory, thus avoiding disk accesses.
TCP_DENIED ::: Access was denied for this request.
TCP_OFFLINE_HIT ::: The requested object was retrieved from the cache during offline mode. The offline mode never validates any object, see offline_mode in squid.conf file.
TCP_STALE_HIT ::: The object was cached and served stale. This is usually caused by stale-while-revalidate or stale-if-error.
TCP_ASYNC_HIT ::: A background request (e.g., one started by stale-while-revalidate) resulted in a refresh hit.
TCP_ASYNC_MISS ::: A background request (e.g., one started by stale-while-revalidate) resulted in a miss; i.e., the cached object (if any) was updated).
UDP_HIT ::: A valid copy of the requested object was in the cache.
UDP_MISS ::: The requested object is not in this cache.
UDP_DENIED ::: Access was denied for this request.
UDP_INVALID ::: An invalid request was received.
UDP_MISS_NOFETCH ::: During "-Y" startup, or during frequent failures, a cache in hit only mode will return either UDP_HIT or this code. Neighbours will thus only fetch hits.
NONE ::: Seen with errors and cachemgr requests.
The following codes are no longer available in Squid-2:
ERR_* ::: Errors are now contained in the status code.
TCP_CLIENT_REFRESH ::: See: TCP_CLIENT_REFRESH_MISS.
TCP_SWAPFAIL ::: See: TCP_SWAPFAIL_MISS.
TCP_IMS_MISS ::: Deleted, now replaced with TCP_IMS_HIT.
UDP_HIT_OBJ ::: Refers to an old version that would send cache hits in ICP replies. No longer implemented.
UDP_RELOADING ::: See: UDP_MISS_NOFETCH.
