redis-fainaでよく使用されるコマンドを確認する
redis-faina使おうとするときすぐ使えるようにするメモ。
RedisのMonitorコマンドを使って出力した情報をsummaryしてくれるすごいツール。 Monitorしてると負荷上がるからなにかある時に使う。
ダウンロード
git clone https://github.com/facebookarchive/redis-faina.git
準備
redis-benchmarkを使用してそのワークロード実行しておく
# redis-benchmark ====== PING_INLINE ====== 100000 requests completed in 0.83 seconds 50 parallel clients 3 bytes payload keep alive: 1 100.00% <= 0 milliseconds 120192.30 requests per second ====== PING_BULK ====== 100000 requests completed in 1.01 seconds 50 parallel clients 3 bytes payload keep alive: 1 100.00% <= 0 milliseconds 98522.17 requests per second ====== SET ====== 100000 requests completed in 0.91 seconds 50 parallel clients 3 bytes payload keep alive: 1 99.95% <= 1 milliseconds 99.95% <= 15 milliseconds 99.98% <= 16 milliseconds 100.00% <= 16 milliseconds 110375.27 requests per second ====== GET ====== 100000 requests completed in 0.89 seconds 50 parallel clients 3 bytes payload keep alive: 1 100.00% <= 0 milliseconds 112612.61 requests per second ・ ・ ====== MSET (10 keys) ====== 100000 requests completed in 3.39 seconds 50 parallel clients 3 bytes payload keep alive: 1 0.01% <= 1 milliseconds 98.14% <= 2 milliseconds 100.00% <= 3 milliseconds 100.00% <= 3 milliseconds 29455.08 requests per second
redis-benchmark実行中にmonitorコマンド使用して、ファイルにリダイレクトさせておく。 CTRL+Cとかで終了もできる。
# redis-cli monitor > monitor.txt
redis-faina実行して確認する
