Lagi chek end rechek squid pelanggan di mabar sana. Tau tau ada pesan TCP_SWAPFAIL_MISS dan TOP proses menunjukkan indikasi terisinya swap, yang konon kata mereka yang jago jago soal mesin squid, terisinya swap sangat di haramkan.
Bingung dan tak tau arti ketika melihat pesan TCP_SWAPFAIL_MISS di access.log yang dapat di lihat dengan perintah tail -f /var/log/squid/access.log yang menunjukkan TCP_SWAPFAIL_MISS
Tidak ada cara lain untuk mengetahui apa arti TCP_SWAPFAIL_MISS
selain bercengkrama dengan tuan segala tau yakni mr google. Dan saya di referensinya ke sebuah web yang menyatakan bahwa arti TCP_SWAPFAIL_MISS adalah Objek sudah ada di dalam cache namun tak dapat di access.
oh ternyata pesan itu hanya bermakna sesingkat itu, dan pesan pesan lainnya mana tau muncul didepan adan saat melihat access.log dapat anda lihat di bawah ini
- 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_REF_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.
- 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, TCP_IMS_HIT used instead.
- UDP_HIT_OBJ
- Hit objects are no longer available.
- UDP_RELOADING
- See: UDP_MISS_NOFETCH.
