Memcache unavailability prevents hit tracking
warningavailabilityUpdated Mar 7, 2014(via Exa)
How to detect:
Hit tracking depends entirely on memcache availability. If memcache service is unavailable or the HITCOUNT_CACHE key is not configured in Django CACHES settings, all hit tracking fails. No database queries occur on requests, so there is no fallback mechanism.
Recommended action:
Ensure memcache service is running and healthy. Verify Django CACHES dict includes the key specified by HITCOUNT_CACHE setting (default 'cached_hitcount'). Monitor memcache availability and django.cache metrics to detect cache backend failures.
