Method Detail

getStats

public TextTable getStats()

Deprecated.

This method is used for dynamic memcache stats gathering. We only gather and print out the following stats in a single row: cur_itms bytes cur_conns sets gets get_hits get_misses evicts bytes_r, bytes_w Since memcached returns cumulative stats, we do the subtraction to get the stats for this interval and then figure out stats/sec

Returns:

TextTable - a single row of stats
