pgbadger监控安装和使用

https://github.com/dalibo/pgbadger/tree/v3.3   --安装包的下载地址，可以随意选择自己想要的版本

1、解压下载的安装包
drwxr-xr-x 3 root root   4096 May  5 08:19 pgbadger-5.1  --解压出来的目录
-rw-r--r-- 1 root root 275644 Sep  3 03:21 pgbadger-5.1.zip

2、安装
[root@localhost ~]# cd pgbadger-5.1

Looks good
Writing Makefile for pgBadger

[root@localhost pgbadger-5.1]# make
cp pgbadger blib/script/pgbadger
/usr/bin/perl "-MExtUtils::MY" -e "MY->fixin(shift)" blib/script/pgbadger
Manifying blib/man1/pgbadger.1
[root@localhost pgbadger-5.1]# make install

Appending installation info to /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/perllocal.pod

3、查看安装版本
[root@testos ]# which pgbadger
/usr/bin/pgbadger
[root@testos ~]# pgbadger -V
pgBadger version 5.1

4、设置postgresql.conf
log_line_prefix = '%t-%d-%h-%a :'  
                                        #   %a = application name
                                        #   %u = user name
                                        #   %d = database name
                                        #   %r = remote host and port
                                        #   %h = remote host
                                        #   %p = process ID
                                        #   %t = timestamp without milliseconds
                                        #   %m = timestamp with milliseconds
                                        #   %i = command tag
                                        #   %e = SQL state
                                        #   %c = session ID
                                        #   %l = session line number
                                        #   %s = session start timestamp
                                        #   %v = virtual transaction ID
                                        #   %x = transaction ID (0 if none)
                                        #   %q = stop here in non-session

5、网页查看
http://192.168.10.173/out.html  --暂时打不开，还有没装完的。

6、安装httpd、php
yum install httpd      ---要先自己配置yum，才能使用yum install 进行安装
chkconfig httpd on     --添加到自动启动
service httpd start
yum install php

/var目录下就多了www目录
[root@localhost www]# ll
total 32
drwxr-xr-x 2 root root 4096 Jul 15  2009 cgi-bin
drwxr-xr-x 3 root root 4096 Sep  3 03:39 error
drwxr-xr-x 2 root root 4096 Jul 15  2009 html
drwxr-xr-x 3 root root 4096 Sep  3 03:39 icons
[root@localhost www]# pwd
/var/www


7、在html下新建php文件，并测试http://192.168.10.173:/test.php能否正常打开
网页显示如下：
<?
phpinfo();
?>
---显示图形化界面才是正确的，而不是只读取文本内容

8、安装apache
>tar -zxvf httpd-2.2.11.tar.gz 
>cd httpd-2.2.11 
>./configure --prefix=/usr/local/apache
make
make install

9、重启apache服务，再次验证
vi /usr/local/apache/conf/httpd.conf
找到"DirectoryIndex index.html在index.html 前添加 test.php

service httpd restart
http://192.168.10.173:/test.php --可以看到图形化界面

10、想办法把pg监控的log显示到这个界面
vi  /etc/httpd/conf/httpd.conf    修改两处
DocumentRoot "/var/www/"    --这样就可以读取www下面所有的目录和文件，因为我在/var/www下面新建了一个pgbadger子目录，out.html就放在下面
                            如果不修改设置，就会提示找不到/pgbadger/out.html


11、尝试手动执行
cd /usr/bin
[root@localhost bin]# pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.csv -o /var/www/pgbadger/out.html
Can't locate Text/CSV_XS.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/bin/pgbadger line 1583.
---看样子应该是没办法读取csv格式的文件


修改配置文件，将日志文件改成log
log_destination = 'csvlog'             # Valid values are combinations of 
                                        # stderr, csvlog, syslog, and eventlog,
                                        # depending on platform.  csvlog
                                        # requires logging_collector to be on.

# This is used when logging to stderr:
logging_collector = on          # Enable capturing of stderr and csvlog
                                        # into log files. Required to be on for
                                        # csvlogs.
                                        # (change requires restart)

# These are only used if logging_collector is on:
log_directory = '/pg/pg_log1'           # directory where log files are written,
                                        # can be absolute or relative to PGDATA
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' # log file name pattern, 

12、再次执行
[root@localhost bin]# pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.log -o /var/www/pgbadger/out.html
FATAL: unable to detect log file format from /pg/pg_log1/postgresql-2014-09-03_193449.log, please use -f option.   ---无法检测格式

需要指定格式
[root@localhost pg_log1]# pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.csv -o /var/www/pgbadger/out.html -f csv    --报错
Can't locate Text/CSV_XS.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/bin/pgbadger line 1583.

[root@localhost pg_log1]# pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.csv -o /var/www/pgbadger/out.html -f stderr  --正确
[========================>] Parsed 441 bytes of 441 (100.00%), queries: 0, events: 0

或者
pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.log -o /var/www/pgbadger/out.html -f csvlog 

13、验证成功
http://192.168.12.173:/pgbadger/out.html
可以打开监控页面，但是完全无数据
[root@localhost bin]# pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.log -o /var/www/pgbadger/out.html  -不添加格式后，又可以了
[========================>] Parsed 4303 bytes of 4303 (100.00%), queries: 8, events: 6
LOG: Ok, generating html report...

--Ok,搞定，可以在网页上面看到监控的数据了。


14、定期执行命令
[root@localhost ~]# cat run.sh
#!/bin/bash
/usr/bin/pgbadger --prefix '%t-%d-%h-%a :' /pg/pg_log1/*.log  -o /var/www/pgbadger/out.html

vi /etc/crontab
0 */1 * * * root /root/run.sh




============================再次安装pgbadger====================
[root@pg pgbadger]# find / -name "pgbadger"
/var/www/html/pgbadger
/var/www/html/pgbadger/blib/script/pgbadger
/var/www/html/pgbadger/pgbadger
/usr/local/bin/pgbadger

[root@pg pgbadger]# cat run.sh
#!/bin/bash
/usr/local/bin/pgbadger --prefix '%t-%d-%h-%a :' /home/pgsql/9.1/data/pg_log/postgresql-201* -o /var/www/html/pgbadger/out.html

1、下载
https://github.com/dalibo/pgbadger
https://github.com/dalibo/pgbadger/releases

2、安装 --192.168.12.29

/usr/local/bin/pgbadger
[root@antiywh-5NMQMH1 ~]# pgbadger -V
pgBadger version 7.1


3、安装php和httpd依赖包
yum install -y  httpd  httpd-devel php  php-devel 
chkconfig httpd on
[root@antiywh-5NMQMH1 ~]# service httpd start
正在启动 httpd：httpd: Could not reliably determine the server's fully qualified domain name, using 220.250.64.18 for ServerName
                                                           [确定]
[root@antiywh-5NMQMH1 data]# service httpd restart
停止 httpd：                                               [确定]
正在启动 httpd：                                           [确定]
                                                        
                                                         
4、安装apache
>tar -zxvf httpd-2.2.11.tar.gz 
>cd httpd-2.2.11 
>./configure --prefix=/usr/local/apache
make && make install

5、修改一些pg库的参数
logging_collector = on
#log_destination = 'stderr'
#log_directory = 'pg_log'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_line_prefix = '%t-%d-%h-%a :'

6、修改参数
vi  /etc/httpd/conf/httpd.conf
DocumentRoot "/var/www/"     --这样就可以读取www下面所有的目录和文件，因为我在/var/www下面新建了一个pgbadger子目录，out.html就放在下面
                            如果不修改设置，就会提示找不到/pgbadger/out.html
ServerName  127.0.0.1:80
<Directory "/var/www/pgbadger">   --指定具体目录
Options Indexes FollowSymLinks
Order allow,deny
Allow from all
AllowOverride All
</Directory>
                          
vi /usr/local/apache/conf/httpd.conf
写一个网页验证：
[root@antiywh-5NMQMH1 pgbadger]# pwd
/var/www/pgbadger
[root@antiywh-5NMQMH1 pgbadger]# cat test.php
<?php
echo "tina's website";
?>

7、重启apache服务，再次验证
service httpd restart
http://192.168.12.29:/pgbadger/test.php


若是启动报错，说端口占用，就先kill掉
[root@antiywh-5NMQMH1 html]# netstat -lnp|grep 80
tcp        0      0 :::80                       :::*                        LISTEN      16634/httpd        
[root@antiywh-5NMQMH1 html]# ps 16634
  PID TTY      STAT   TIME COMMAND
16634 ?        Ss     0:00 /usr/local/apache/bin/httpd -k start

kill -9 16634 

8、启动pgbadger的
/usr/local/bin/pgbadger --prefix '%t-%d-%h-%a :' /home/pgsql/9.1/data/pg_log/postgresql-201* -o /var/www/html/pgbadger/out.html

CPAN（Comprehensive　Perl　Archive　Network）是internet上Perl模块最大的集散地，包含了现今公布的几乎所有的perl模块，
通过上面的例子，可以获知利用这个格式，可以到CPAN上安装需要的模块。


到CPAN的官方站点下载CPAN模块
   http://search.cpan.org/~andk/CPAN-1.9301/lib/CPAN.pm

解压，编绎，安装
