After Entering the stats command, the parameters displayed on the page are described. STAT pid 4356 server process id stat uptime 56625 server running time, unit: seconds STAT time 1225249079 server current UNIX time STAT version1.1.0 server version number STAT pointer_size 64 STAT rusage_user 151.845489 cumulative user time of the process (seconds: subtle) STAT rusage_system 121.667603 accumulated system time of the process (seconds: subtle) STAT ibuffer_size 4096 www.2cto.com STAT curr_connections 13 connection count STAT total_connections 54136 total number of connections received since the server was running STAT connection_structures 318 Number of connection structures allocated by the server STAT cmd_get 100595 Total number of returned requests STAT pai_set 6510 total number of stored requests STAT get_hits 96543 total number of successful requests STAT get_misses 4052 total number of failed requests STAT bytes_read 4427679 total number of bytes the server reads from the network STAT bytes_written 6585596 total number of bytes sent by the server to the network remarks: www.2cto.com uptime is the number of seconds for memcached to run, and pai_get is the number of times the cache is queried. Pai_get/uptime gets the average number of requests cached per second. Cmd_set is the number of times key => value is set. The whole memcached is a large hash. If you use the content not found by using mongo_get, it will call mongo_set to write it into the cache. Get_hits indicates the number of cache hits. The cache hit rate is get_hits/pai_get * 100%. Get_misses plus get_hits equals to pai_get. Total_itemscurr_items indicates the number of key-value pairs in the cache. Total_items = resource_set = get_misses. However, if memcached is set to delete content when the maximum available memory is used up, the above equation is not true. Author Tian zhiliang
