DBA如何定制自动化巡检工具

## 一、逐步实现自动化的基本步骤

1.手动巡检

最初阶段,多数DBA习惯于将常用的SQL语句总结记录下来,在日常巡检的时候,会在数据库中执行常用的SQL语句,然后以抓屏方式将结果复制出来,然后逐条检查分析。这种方法只适合于管理少量数据库,一旦数据库数量增加,工作量会非常大。

2.脚本巡检

升级阶段,具备脚本语言开发功底的DBA会逐步将常用的SQL语句编制为固定SQL脚本,然后通过操作系统可执行的脚本语言(例如:KSH、BASH),通过Shell脚本去调用SQL脚本,并把执行结果写入日志文件,后期通过日志文件去进行检查分析。这种方法可管理较多数据库,但是需要频繁切换到不同的数据库服务器,容易误操作,尤其是操作系统平台不统一的场景。

3.自动化巡检

最终阶段,具备Python、Expect等语言开发功底的DBA会逐步将常前面的成果物积淀下来,然后通过Python脚本的方式去自动调用各个系统的Shell脚本,从而批量完成所有数据库的巡检过程,并将所有数据库的巡检日志传输至集中位置。再通过文本过滤工具(例如:AWK)或者VBA对日志内容进行过滤筛选,最后对过滤后的内容进行最终分析。这种方法可以通过集中管理服务器对所有数据库服务器进行批量操作,并且消除了操作系统平台不一致带来的问题。

二、需要获取的数据库诊断信息

1. 基本信息

基本信息根据不同的数据库环境会有所差异,但是有些最基本的信息是必须的。如数据库名称、实例名称、唯一标识信息、系统版本、地址信息、数据库创建时间、数据库启动时间、数据库版本信息、数据库补丁信息、字符集、实例状态、数据库归档模式等。以下脚本(for Oracle)供参考:

SELECT name AS db_name,
       dbid,
       created,
       platform_name,
       db_unique_name,
       log_mode,
       guard_status,
       force_logging,
       flashback_on
  FROM v$database;

SELECT instance_name,
       inst_id,
       host_name,
       TO_CHAR(startup_time, 'YYYY/MM/DD HH24:MI:SS') AS startup_time,
       status,
       SYSDATE - STARTUP_TIME AS Running_Time
  FROM gv$instance
 ORDER BY inst_id;

2. 存储信息

存储信息包括逻辑存储信息和物理存储信息,具体包含数据库的表空间、数据文件、磁盘三个维度。表空间需要收集表空间名称,类型,区管理方式,区初始大小,段的管理方式,总大小,剩余大小,剩余百分比;数据文件需要收集对应的表空间,是否自动扩展,当前值,最大值等;磁盘信息需要收集磁盘组的序号、名称、冗余类型、总大小、剩余大小、使用频繁的数据大小、镜像需要的空间、可用于镜像的大小、offline的磁盘数量等。以下脚本(for Oracle)供参考:

SELECT c.tablespace_name,
       c.contents,
       c.extent_management ext_mgmt,
       c.allocation_type alloc_type,
       c.initial_extent / 1024 ext_kb,
       c.segment_space_management SSM,
       nvl(a.total_gb, 0) total_gb,
       decode(c.contents, 'TEMPORARY', nvl(a.total_gb, 0) - c.block_size * b.used_blocks / 1073741824, nvl(b.free_gb, 0)) free_gb,
       100 *  decode(c.contents, 'TEMPORARY', nvl(a.total_gb, 0) - c.block_size * b.used_blocks / 1073741824, nvl(b.free_gb, 0)) / nvl(a.total_gb, 1) free_pct
  FROM (SELECT tablespace_name, nvl(sum(bytes) / 1073741824, 0) total_gb
          FROM dba_data_files
         GROUP BY tablespace_name
         UNION all
        SELECT tablespace_name, nvl(sum(bytes) / 1073741824, 0) total_gb
          FROM dba_temp_files
         GROUP BY tablespace_name) a,
       (SELECT tablespace_name,
               nvl(sum(bytes) / 1073741824, 0) free_gb,
               0 used_blocks
          FROM dba_free_space
         GROUP BY tablespace_name
         UNION all
        SELECT tablespace_name,
               0 free_gb,
               nvl(sum(used_blocks), 0) used_blocks
          FROM gv$sort_segment
         GROUP BY tablespace_name) b,
       dba_tablespaces c
 WHERE c.tablespace_name = b.tablespace_name(+)
   AND c.tablespace_name = a.tablespace_name(+)
 ORDER BY c.contents, free_pct, c.tablespace_name;
 
 SELECT file_id,
       file_name,
       tablespace_name,
       autoextensible,
       bytes / 1073741824 as current_gb,
       maxbytes / 1073741824 as max_gb
  FROM dba_data_files
 UNION
SELECT file_id,
       file_name,
       tablespace_name as ts_name,
       autoextensible,
       bytes / 1073741824 as cur_gb,
       maxbytes / 1073741824 as max_gb
  FROM dba_temp_files
 ORDER BY tablespace_name, file_id, file_name;
 
 SELECT group_number,
       name,
       type,
       total_mb,
       free_mb,
       hot_used_mb,
       required_mirror_free_mb,
       usable_file_mb,
       offline_disks 
  FROM v$asm_diskgroup_stat;

3. 日志信息

日志信息主要是对联机日志、快速恢复日志相关动态信息的统计分析。具体包括联机日志的组号、线程号、序列号、文件路径、大小、状态、归档状态、组内成员数量;归档日志产生日期,产生的大小,和文件数等;每天日志切换的量以及切换的频率。以下脚本(for Oracle)供参考:

SELECT t2.member,
       t1.group#,
       t1.thread#,
       t1.sequence#,
       t1.bytes / 1024 / 1024 AS SIZE_MB,
       t1.status,
       t1.archived,
       t1.members
  FROM v$log t1, v$logfile t2
 WHERE t1.group# = t2.group#
 ORDER BY thread#, group#;
 
 SELECT lpad(to_char(first_time, 'yyyymmdd'), 12) "DATE",
       trunc(sum(blocks * block_size) / 1024 / 1024) "SIZE(MB)",
       count(*)
  FROM v$archived_log
 WHERE first_time > sysdate - 6
   AND creator = 'ARCH'
 GROUP BY lpad(to_char(first_time, 'yyyymmdd'), 12)
 ORDER BY 1;
 
 SELECT SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH:MI:SS'),1,5) Day,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'00',1,0)) H00,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'01',1,0)) H01, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'02',1,0)) H02,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'03',1,0)) H03,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'04',1,0)) H04,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'05',1,0)) H05,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'06',1,0)) H06,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'07',1,0)) H07,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'08',1,0)) H08,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'09',1,0)) H09,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'10',1,0)) H10,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'11',1,0)) H11, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'12',1,0)) H12,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'13',1,0)) H13, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'14',1,0)) H14,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'15',1,0)) H15, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'16',1,0)) H16, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'17',1,0)) H17, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'18',1,0)) H18, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'19',1,0)) H19, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'20',1,0)) H20, 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'21',1,0)) H21,
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'22',1,0)) H22 , 
       SUM(DECODE(SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH24:MI:SS'),10,2),'23',1,0)) H23, 
       COUNT(*) TOTAL 
  FROM v$log_history  a  
 WHERE first_time>=to_char(sysdate-7)
 GROUP BY SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH:MI:SS'),1,5) 
 ORDER BY SUBSTR(TO_CHAR(first_time, 'MM/DD/RR HH:MI:SS'),1,5) DESC;
 
 SELECT thread#, 
       sequence#, 
       to_char(first_time, 'MM/DD/RR HH24:MI:SS')
  FROM v$log_history
 WHERE thread# = 1
   AND first_time > sysdate - 1
 ORDER BY first_time DESC;

SELECT thread#, 
       sequence#, 
       to_char(first_time, 'MM/DD/RR HH24:MI:SS')
  FROM v$log_history
 WHERE thread# = 2
   AND first_time > sysdate - 1
 ORDER BY first_time DESC;

4. 备份信息

备份信息主要是查看数据库备份任务的执行情况。主要包括备份任务的会话信息标识,备份内容,开始时间,结束时间,消耗时间。以下脚本(for Oracle)供参考:

SELECT session_key,
       start_time,
       end_time,
       status,
       time_taken_display tt
  FROM v$rman_backup_job_details
 WHERE start_time > sysdate -1
 ORDER BY session_key;

5. 性能信息

数据库性能诊断分析的基本目标分两个方面,一方面要看数据库本身跟性能有关的资源使用情况是否正常,另外一方面就是要抓取异常的会话、事件、SQL等。因此,这部分内容首先要收集数据库缓存使用情况,然后要收集异常会话以及相关进程的资源参数,24小时内CPU等待最长的事件,执行解析最多的SQL语句等。以下脚本(for Oracle)供参考:

SELECT free_space,
       avg_free_size,
       used_space,
       avg_used_size,
       request_failures,
       last_failure_size 
  FROM v$shared_pool_reserved;
  
  SELECT *
  FROM (SELECT t.sid,
               t.serial#,
               trunc(sysdate - logon_time) AS online_time,
               t.PROGRAM,
               t.status,
               t.LOGON_TIME,
               t.sql_id,
               t.prev_sql_id,
               t.event
          FROM gv$session t
         WHERE t.type <> 'BACKGROUND' AND program is not null
         ORDER BY logon_time)
 WHERE rownum <= 30;
 
 SELECT * 
  FROM gv$resource_limit  
 WHERE trim(limit_value) != 'UNLIMITED';
 
 SELECT t.*, s.sid, s.serial#, s.machine, s.program, s.osuser
  FROM (SELECT c.USERNAME, a.event, to_char(a.cnt) as seconds, a.sql_id, dbms_lob.substr(b.sql_fulltext, 100, 1) sqltext
          FROM (SELECT rownum rn, t.*
                  FROM (SELECT decode(s.session_state, 'WAITING', s.event, 'Cpu + Wait For Cpu') Event, s.sql_id, s.user_id, count(*) cnt
                          FROM v$active_session_history s
                         WHERE sample_time > sysdate - 1
                         GROUP BY s.user_id, decode(s.session_state, 'WAITING', s.event, 'Cpu + Wait For Cpu'), s.sql_id
                         ORDER BY cnt DESC) t
                 WHERE rownum < 20) a, v$sqlarea b, dba_users c
         WHERE a.sql_id = b.sql_id AND a.user_id = c.user_id
         ORDER BY cnt DESC) t, v$session s
 WHERE t.sql_id = s.sql_id(+);
 
 SELECT *
  FROM (SELECT sql_id, sql_text, s.executions, s.last_load_time, s.first_load_time, s.disk_reads, s.buffer_gets, s.parse_calls
          FROM v$sql s
      ORDER BY s.executions DESC)
 WHERE rownum <= 10;
 
 SELECT *
  FROM (SELECT sql_id, sql_text, s.EXECUTIONS, s.LAST_LOAD_TIME, s.FIRST_LOAD_TIME, s.DISK_READS, s.BUFFER_GETS, s.PARSE_CALLS
          FROM v$sql s
      ORDER BY s.PARSE_CALLS DESC)
 WHERE rownum <= 10;

6. 容灾信息

所谓容灾信息就是指数据库有容灾配置模式的场景,比如Oracle的Data Guard。如果有相关的配置,则需要检查主备库的同步是否异常,主要通过归档日志的同步信息来判断分析。这个时候需要获取归档目标名称、状态、数据库当前模式、目的地路径等静态信息,需要获取每个节点应用日志和归档日志的最大号,SCN最大值和最小值等相关信息。以下脚本(for Oracle)供参考:

SELECT dest_name,
       status,
       database_mode,
       destination  
  FROM v$archive_dest_status 
 WHERE dest_id in ('1','2');
 
 SELECT m.thread#, 
       m.sequence#, 
       first_change#, 
       next_change#
  FROM v$log_history m,
       (SELECT thread#, max(sequence#) as sequence#
          FROM v$log_history
      GROUP BY thread#) t
 WHERE m.thread# = t.thread#
   AND m.sequence# = t.sequence#;
   
   SELECT UNIQUE thread# AS thread, 
       MAX(sequence#) OVER (PARTITION BY thread#) AS last 
  FROM v$archived_log;

三、实现自动化脚本集成

1. 将基本SQL文转换成可用SQL脚本

通过手动执行SQL命令的方式,查询结果可以展现在屏幕上。但是以脚本后台模式执行的时候,就需要将查询结果格式化之后输入到结果文件当中。可以采用文本文件或者HTML文件。采用文件文件的时候,需要对输出结果进行美观易读方面的格式化,想再升级为HTML文件时,SQL脚本中要加HTML头。例如以下是格式化之前和之后的对比:

PROMPT <p><h1 class="awr">XX公司数据库巡检报告</h1>
PROMPT <p><a class="awr">数据库基本信息 </a>
COLUMN log_mode FOR a12 
COLUMN guard_status FOR a10
COLUMN force_logging FOR a15
COLUMN flashback_on  FOR a15
COLUMN db_unique_name FOR a10
COLUMN platform_name FOR a20
SELECT name AS db_name,
       dbid,
       created,
       platform_name,
       db_unique_name,
       log_mode,
       guard_status,
       force_logging,
       flashback_on
  FROM v$database;

2. 通过Shell脚本调用SQL脚本

如果单纯通过Shell脚本完成对SQL脚本的调用还是有些单薄。因此Shell脚本的设计需要完成两方面的功能,一方面需要收集操作系统相关的诊断信息,另外一方面要定义SQL脚本执行的初始化参数,完成对SQL脚本的调用执行。对于操作系统级别的诊断信息收集,无非是在Shell当中调用操作系统命令,如:uptime、vmstat、free、df、sar、iostat;对于SQL脚本的调用,需要完善相关初始化信息,如位置信息(脚本位置、输入文件位置、数据库安装目录等相关信息),时间信息(执行日期、时间),连接必要信息(用户、数据库名称、标识等)。 以下调用过程脚本片段供参考:

function _dbinfo(){
cd $PWDDIRECTORY
su - oracle -c "cd $LOGDIR/db;export ORACLE_SID=$1;sqlplus -s /nolog <<EOF
conn / as sysdba;
@$LOGDIR/../dailyhealthycheck_withadg.sql
exit;
EOF"
}

3. 通过Python脚本实现集中自动化调用

对于这个步骤实现的功能有两个重点,一个是完成集中化的优势,一个是完成自动化交互的功能。集中化的优势需要在循环语句当中完成。自动化交互的功能本来就是Python之类脚本语言的优势。只是我们在调用的时候需要考虑的初始化参数的定义和确认。 以下调用过程脚本片段供参考:

def ssh_cmd(ip, user, passwd, cmd):
    ret = -1
    ssh = pexpect.spawn('ssh %s@%s "%s"' % (user,ip, cmd),timeout=120)
    try:
        i = ssh.expect(['password:', 'continue connecting (yes/no)?'], timeout=5)
        if i == 0 :
            ssh.sendline(passwd)
        elif i == 1:
            ssh.sendline('yes\\n')
            ssh.expect('password: ')
            ssh.sendline(passwd)
        ssh.sendline(cmd)
        r = ssh.read()
    print (r)
        ret = r
    except pexpect.EOF:
        print ("EOF")
        ssh.close()
        ret = -1
    except pexpect.TIMEOUT:
    print ("TIMEOUT")
    ssh.close()
    ret = -2
    return ret

4. 工具化产品化打造过程

大部分数据库管理员设计脚本工具都是为了便于自己的日常管理工作,基本上不会考虑到工具的可维护性、健壮性、规范化以及未来的扩展性。如果想让自己辛苦设计出来的脚本最终可以转化为自动化运维工具,那么还要考虑到以下三个方面的问题:

(1). 遵循开发者规范,将脚本的设计趋向于标准化、模块化。例如脚本注释标准化,利用函数模块化设计,变量定义规范化。
(2). 每一个执行步骤要考虑到执行前的确认步骤,执行后的反馈步骤,执行中的异常处理场景。
(3). 所有参数输入尽量采用变量化设计,所有常量以文件方式隔离出脚本本身。

四、参考脚本
