Greenplum Command Center是Greenplum提供的监控软件，它之前的名字是Greenplum Performance Monitor。
一、Greenplum Command Center介绍
Greenplum Command Center用于监控系统性能指标、分析系统健康、管理执行管理任务（如start 、stop、恢复Greenplum等）。
它由data collection agent和Command Center等组件组成：
- Agent：安装在master及其他segment节点上，用于收集数据，包括查询、系统指标等。Master节点的agent轮询收集segment的agent数据，然后发送给Command Center Database。
- Command Center Database：存放agent收集的数据和指标，然后运算后通过web界面展现。它存放在Greenplum Database的gpperfmon库里。
- Greenplum Command Center Console：提供图形终端用于查看系统指标和性能。
- Greenplum Command Center Web Service：Greenplum Command Center Console通过web service框架来访问Command Center 数据库。使用的是Lighttpd服务器。
greenplum Command Center 架构
二、开启数据收集agent
Greenplum提供了gpperfmon_install工具部署agent，这个工具会进行如下操作。
- 创建Command Center数据库（gpperfmon）；
- 创建Command Center超级用户（gpmon）；
- 配置Greenplum database server允许Command Ceneter的超级用户gpmon访问（编辑pg_hba.conf和.pgpass文件）；
- 在Greenplum database server的postgresql.conf文件中天津Command Ceneter的参数。
在Master节点配置：
1、登录gpadmin用户
2、加载Greenplum Database Ceneter的环境变量

$ source /opt/greenplum/greenplum-db/greenplum_path.sh |
3、运行gpperfmon_install工具，提供Greenplum Database master的端口，设置gpmon用户密码。

4、重启Greenplum DB，重启后data collection agent才会启动
|
1 |
$ gpstop -r |
5、确定Master节点上data collection进程在运行
|
1 2 3 |
$ ps -ef|grep gpmmon gpadmin 2246 2216 0 13:22 pts/1 00:00:00 grep gpmmon gpadmin 21632 21623 0 10:53 ? 00:00:01 /opt/greenplum/greenplum-db-4.3.6.2/bin/gpmmon -D /home/gpadmin/master/gpseg-1/gpperfmon/conf/gpperfmon.conf -p 5432 |
6、确定data collection 进程已经把数据写入到了Command Center数据库。如果所有segment data collection agent在运行，你可以看到segment记录。
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |

查看gpperfmon数据库中的内容
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |

7、配置standby master
把Master上的$MASTER_DATA_DIRECTORY/pg_hba.conf文件拷贝到standby master上。确保Command Ceneter也能够访问standby master。拷贝Master的 ~/.pgpass文件到standby master。注意.pgpass文件的权限是600。
|
1 2 3 4 5 6 |
$ gpscp -h gp-s1 /home/gpadmin/master/gpseg-1/pg_hba.conf =:$MASTER_DATA_DIRECTORY/ $ gpscp -h gp-s1 ~/.pgpass =:~/ $ gpssh -h gp-s1 => chmod 600 ~/.pgpass [gp-s1] |
三、安装Greenplum Command Center Console控制台
Command Ceneter Console提供了一个图形节目，用来查看数据库性能。它部署在Master节点。也可以部署在其他节点上，由于大量连接连接console控制台，可能会导致潜在性能风险。
特别提醒，浏览器一定用最新的Adobe Flash Player。Command Ceneter Console运行在lighted web server上，默认端口是28080.
1、安装Command Ceneter Console 软件
<1>下载安装包
https://network.pivotal.io/products/pivotal-gpdb#/releases/669/file_groups/26
<2>解压并运行安装包
|
1 2 3 4 5 6 |
# su - gpadmin $ unzip greenplum-cc-web-2.0.0-build-32-RHEL5-x86_64.zip Archive: greenplum-cc-web-2.0.0-build-32-RHEL5-x86_64.zip inflating: greenplum-cc-web-2.0.0-build-32-RHEL5-x86_64.bin $ sh greenplum-cc-web-2.0.0-build-32-RHEL5-x86_64.bin |
Command Ceneter Console默认安装路径是/usr/local/greenplum-cc-web-2.0.0-build-32，但是该路径由于权限安装不方便。
选择和Greenplum DB软件公用一个目录，gpadmin用户有这个目录的权限。这样运行gpccinstall命令，传输到其他节点的时候不存在权限问题。
|
1 2 |
$ cd /opt/greenplum/ $ mkdir gpcc |
运行安装包过程中，阅读协议直到底部输入yes同意协议，回车确定安装路径，直到安装成功。
