cache のキーの一覧を取る
まず stats slabsを実行する。
>stats slabs STAT 1:chunk_size 80 STAT 1:chunks_per_page 13107 STAT 1:total_pages 1 STAT 1:total_chunks 13107 STAT 1:used_chunks 13105 STAT 1:free_chunks 2 STAT 1:free_chunks_end 13105 STAT 2:chunk_size 100 STAT 2:chunks_per_page 10485 STAT 2:total_pages 1 STAT 2:total_chunks 10485 STAT 2:used_chunks 10484 STAT 2:free_chunks 1 STAT 2:free_chunks_end 10484 STAT 3:chunk_size 128 STAT 3:chunks_per_page 8192 STAT 3:total_pages 1 STAT 3:total_chunks 8192 STAT 3:used_chunks 8185 STAT 3:free_chunks 7 STAT 3:free_chunks_end 8178 STAT active_slabs 3 STAT total_malloced 3145636
この結果のSTATの後の数字を次のコマンドに使ってstats cachedump を実行する
telnet>stats cachedump <数字> <取得件数>
