といっても 9 割方

• そもそもサーバの設定がおかしい
• 更新が多いテーブルなのに MyISAM エンジン
• for 文の中でクエリを発行
• INDEX 張ってない
• データ量がえらいことになってる

辺りなんですけどねー。

基本は下から

まず，ボトルネックを調べるときは下の層から上がっていくのが基本です。たぶん。

なので ssh でサーバに入って (LoadAverage 300 ぐらいまでならなんとか入れますね) 以下のコマンドをよく叩きます。

top

現在稼動しているプロセスの一覧と，システム情報の概要が表示されるプログラム。

見るのは主に

• Load Average
• CPU 使用率
• メモリ使用量
• swap 使用量

と，これらが異常なプロセス。

たとえば swap だと，正常なときは

Swap:  7879872k total,      764k used,  7879108k free,  3589852k cached

ですが，異常に減っているときは

Swap:  7879872k total,  2529080k used,  5350792k free,  1574320k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
26945 mysql     20   0 7681m 6.0g 5080 S   37 77.2  17214:10 /usr/local/mysql/libexec/mysqld

のようになります。明らかに mysql がメモリ食い潰してますね。 free や ps でも確認出来ますが，どのプロセスが悪いのか見渡しやすいので，僕は top が好きです。

vmstat

これもシステム情報を表示するプログラムです。

• swap が発生しているかどうか
• CPU 使用率が異常な値じゃないか
• CPU IO Wait が発生しているかどうか
• Disk IO が異常値じゃないか
• Context Switch が異常に頻繁だったりしないか

あたりを確認します。

たとえば CPU IO wait が異常なときは

procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----
 r  b   swpd   free   buff  cache   si   so    bi    bo   in   cs us sy id wa
 0 11  20092 281480     12 7671592    0    0 27820    42 1967 2557  3  3 41 52
 0 12  20092 284492     12 7668020    0    0 26512     1 1812 2222  2  3 47 48
 0 13  20092 281188     12 7671080    0    0 33144     0 1890 2258  2  2 40 56
 0 13  20092 277208     12 7674300    0    0 24612     0 1722 2000  2  1 38 59
 0 24  20092 283364     12 7665688    0    0 24304     0 1871 2287  2  2 30 66
 2 21  20092 284912     12 7661960    0    0 31688    30 1714 2130  3  3 35 60

となります。

大抵の場合，以上の 2 コマンドで原因となっているプロセスを特定できるので，新機能のリリース時は 2 画面開いて

• top -d 5
• vmstat 5

として見張っています。

ありがちな例

CPU Usage が高い

大概，インデックスの張り忘れです。インデックスさえ張っておけば一瞬で終わるはずの WHERE 句や ORDER 句を，必死に CPU が計算しています。

最初はデータ量が少なくて気づかないかもしれないけど，次第に CPU 使用率が 100% に限りなく近づいて……。

varchar カラムに対して int を検索条件にする場合は INDEX が使われないので注意してください。 MySQL は文字列の型に対して where hoge = 1 と絞り込むとき，'01' や '1.00' の行もマッチします。つまり INDEX は使えず，全件走査となります。

ソーシャルアプリでは opensocial_owner_id が文字列なのでコレやりがちなんですよね。さすがにすぐ気づくとは思いますが(笑)

CPU IO Wait が高い

データ量に対して，メモリの割り当てが少ない場合とか。

show table status;

したときの Data_length + Index_length と key_buffer_size や innodb_buffer_pool_size を見直してみてください。 せめて Index だけでもメモリに載せてあげたいので。

ディスクの読み書きはメモリの読み書きの 10 万倍遅いです。ディスクアクセスは 1 回につき 5ms 程度かかるので，秒間 200 回しかアクセスできません。

1 回のクエリで 4 回ディスクへのアクセスが発生し，1 ページ表示するのに 5 回クエリを投げるとすると秒間 10 PV しか耐えられないことになります。 1 ユーザあたり 150 PV/day，ピーク時に平均の 2 倍になる場合で 2,500 UU/day が限界な感じですね。これが全てメモリに載っていれば 5 億人までいけます。

実行中のクエリを確認

MySQL の設定ではなくクエリが原因だと判断したら，実行中のクエリを確認します。

• innotop
• show processlist
• mprofile

の 3 パターンかな。

innotop

InnoDB を使ってるときはぜひ。 innotop - Project Hosting on Google Code

僕が注意しているのは

• InnoDB Buffers
  • Hit Rate
• Command Summary
  • Com_select
  • Com_show_status
  • Com_begin
  • Com_commit
  • Com_update
  • Com_insert
• InnoDB I/O Info
  • Reads/Sec
  • Writes/Sec
• Query List

ですね。

トランザクションが重い場合，Query List には「COMMIT;」しか表示されなかったりするので注意してください。

show processlist

innotop や mytop で実行中のクエリのリストが見えるんですが，これらを入れていない場合は show processlist; で確認します。

クエリを全て Info カラムに出力したいときは

show full processlist;

mprofile

Kazuho@Cybozu Labs: MySQL のボトルネックを統計的に監視・解析する方法

show processlist を 1,000 回実行し，どのクエリが何回表示されたかの統計を取ってくれます。何から潰すべきなのかの判断に迷ったらとりあえず統計取りましょう。

奥さんも書いてますが，定期的に実行してログを残しておくと，ユーザの動向と DB の使われ方の変遷が見えてきてサーバ増強計画を作りやすいですね。

……思ってたより長くなったので次回 EXPLAIN 編に続きます。乞うご期待！

A BSD Unix Syslog message looks like this:
<PRI>HEADER MESSAGE

The priority is a value from 0 to 191 and is not space or leading zero padded.
For more information on the Syslog message format, please read the RFC.

The Facility value is a way of determining which process of the machine created the message. Since the Syslog
protocol was originally written on BSD Unix, the Facilities reflect the names of Unix processes and Daemons.
The priority value is calculated using the following formula:

Priority = Facility * 8 + Level

The list of Facilities available:

0 kernel messages
1 user-level messages
2 mail system
3 system daemons
4 security/authorization messages
5 messages generated internally by syslogd
6 line printer subsystem
7 network news subsystem
8 UUCP subsystem
9 clock daemon
10 security/authorization messages
11 FTP daemon
12 NTP subsystem
13 log audit
14 log alert
15 clock daemon
16 local use 0 (local0)
17 local use 1 (local1)
18 local use 2 (local2)
19 local use 3 (local3)
20 local use 4 (local4)
21 local use 5 (local5)
22 local use 6 (local6)
23 local use 7 (local7)

If you are receiving messages from a Unix system, it is suggested you use the 'User' Facility as your first
choice. Local0 through to Local7 are not used by Unix and are traditionally used by networking equipment.
Cisco routers for example use Local6 or Local7.

Syslog Levels

Each Syslog message includes a priority value at the beginning of the text. The priority value ranges from 0 to
191 and is made up of a Facility value and a Level value. The priority is enclosed in "<>" delimiters.
A BSD Unix Syslog message looks like this:

<PRI>HEADER MESSAGE

The priority is a value from 0 to 191 and is not space or leading zero padded.
For more information on the Syslog message format, please read the RFC.
The priority value is calculated using the following formula:

Priority = Facility * 8 + Level

The list of severity Levels:
0 Emergency: system is unusable
1 Alert: action must be taken immediately
2 Critical: critical conditions
3 Error: error conditions
4 Warning: warning conditions
5 Notice: normal but significant condition
6 Informational: informational messages
7 Debug: debug-level messages

Recommended practice is to use the Notice or Informational level for normal messages.

A detailed explanation of the severity Levels:

DEBUG:
Info useful to developers for debugging the app, not useful during operations

INFORMATIONAL:
Normal operational messages - may be harvested for reporting, measuring throughput, etc - no action
required

NOTICE:
Events that are unusual but not error conditions - might be summarized in an email to developers or admins to
spot potential problems - no immediate action required

WARNING:
Warning messages - not an error, but indication that an error will occur if action is not taken, e.g. file system
85% full - each item must be resolved within a given time

ERROR:
Non-urgent failures - these should be relayed to developers or admins; each item must be resolved within a
given time

ALERT:Should be corrected immediately - notify staff who can fix the problem - example is loss of backup ISP
connection

CRITICAL:
Should be corrected immediately, but indicates failure in a primary system - fix CRITICAL problems before
ALERT - example is loss of primary ISP connection

EMERGENCY:
A "panic" condition - notify all tech staff on call? (earthquake? tornado?) - affects multiple apps/servers/sites...

X.I want a RAM disk that uses memory above 4 GB in 32 bit Windows. Can ImDisk do that?

Well, not natively. If your 32 bit Windows version supports memory access above 4 GB through address window extension (AWE) and with physical address extension (PAE) turned on, it could be done through an additional memory allocation driver called awealloc.

Modify awealloc to auto-load at system startup:
sc config awealloc start= system
This will take effect at next reboot. Meanwhile you can load it manually:
net start awealloc

Then, create the RAM disk (schedule this command with Windows Scheduler if you want it to happen automatically at system startup):
imdisk -a -f \\.\awealloc -s 400M -m R: -p "/fs:ntfs /q /y"

This will ask awealloc driver to allocate 400 MB and then create a RAM disk drive R: within that memory and format it with NTFS. The 400 MB will primarily be allocated from as high memory addresses as possible, but parts of it could be allocated at lower addresses if not enough memory is free or otherwise accessible at high ranges. Check Windows Event Log to see error messages during memory allocation.
