memcached_stat, memcached_stat_servername, memcached_stat_get_value, memcached_stat_get_keys - Get memcached statistics
C Client Library for memcached (libmemcached, -lmemcached)
#include <memcached.h> memcached_stat_st *memcached_stat (memcached_st *ptr, char *args, memcached_return_t *error); memcached_return_t memcached_stat_servername (memcached_stat_st *stat, char *args, const char *hostname, unsigned int port); char * memcached_stat_get_value (memcached_st *ptr, memcached_stat_st *stat, const char *key, memcached_return_t *error); char ** memcached_stat_get_keys (memcached_st *ptr, memcached_stat_st *stat, memcached_return_t *error);
libmemcached(3) has the ability to query a memcached server (or collection of servers) for their current state. Queries to find state return a memcached_stat_st structure. You are responsible for freeing this structure. While it is possible to access the structure directly it is not advisable. <memcached_stat_get_value() has been provided to query the structure.
memcached_stat_st
memcached_stat() fetches an array of memcached_stat_st structures containing the state of all available memcached servers. The return value must be freed by the calling application. If called with the MEMCACHED_BEHAVIOR_USE_UDP behavior set, a NULL value is returned and the error parameter is set to MEMCACHED_NOT_SUPPORTED.
MEMCACHED_BEHAVIOR_USE_UDP
MEMCACHED_NOT_SUPPORTED
memcached_stat_servername() can be used standalone without a memcached_st to obtain the state of a particular server. "args" is used to define a particular state object (a list of these are not provided for by either the memcached_stat_get_keys() call nor are they defined in the memcached protocol). You must specify the hostname and port of the server you want to obtain information on.
memcached_st
memcached_stat_get_value() returns the value of a particular state key. You specify the key you wish to obtain. The key must be null terminated.
memcached_stat_get_keys() returns a list of keys that the server has state objects on. You are responsible for freeing this list.
A command line tool, memstat(1), is provided so that you do not have to write an application to do this.
Varies, see particular functions.
Any method returning a memcached_stat_st expects you to free the memory allocated for it.
