An instance name is used by the Greenplum Command Center as
a way to uniquely identify a Greenplum Database that has the monitoring
components installed and configured. This name is also used to control
specific instances of the Greenplum Command Center web UI. Instance names
can contain letters, digits and underscores and are not case sensitive.
Please enter a new instance name:
> myperfmon
The web component of the Greenplum Command Center can connect to a
monitor database on a remote Greenplum Database.
Is the master host for the Greenplum Database remote? Yy|Nn (default=N):
>
The display name is shown in the web interface and does not need to be
a hostname.
What would you like to use for the display name for this instance:

Creating instance schema in GPDB. Please wait ...
The Greenplum Command Center runs a small web server for the UI and web API.
This web server by default runs on port 28080, but you may specify any available port.

Configuring authentication for the monitor console
我们在执行gpperfmon_install的时候，系统帮我们创建了监控数据库的role，默认是gpmon。这个角色是使用md5加密认证来连接greenplum数据库的，如果有一天，你的gpmon连接不上了，我们可以使用gpadmin用户来连接，配置如下1,确定gpadmin用户已经使用md5加密认证
=#alter role gpadmin with encrypted password ‘greenplum’;
2,编辑 $MASTER_DATA_DIRECTORY/pg_hba.conf，使gpadmin能够连接数据库
host gpperfmon all 0.0.0.0/0 md5
3,在gpadmin用户目录下面的.pgpass文件里面添加这样一条信息
*.5432:gpperfmon:gpadmin:greenplum
4,保存退出，重新加载greenplum
$gpstop –u
[gpadmin@mdw gpseg-1]$ tail -50f pg_hba.conf
# of significant bits in the mask. Alternatively, you can write an IP
# address and netmask in separate columns to specify the set of hosts.
# Instead of a CIDR-address, you can write "samehost" to match any of
# the server's own IP addresses, or "samenet" to match any address in
# any subnet that the server is directly connected to.
#
# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
# "krb5", "ident", "pam", "ldap", "radius" or "cert". Note that
# "password" sends passwords in clear text; "md5" is preferred since
# it sends encrypted passwords.
#
# OPTIONS are a set of options for the authentication in the format
# NAME=VALUE. The available options depend on the different
# authentication methods -- refer to the "Client Authentication"
# section in the documentation for a list of which options are
# available for which authentication methods.
#
# Database and user names containing spaces, commas, quotes and other
# special characters must be quoted. Quoting one of the keywords
# "all", "sameuser", "samerole" or "replication" makes the name lose
# its special character, and just match a database or username with
# that name.
#
# This file is read on server startup and when the postmaster receives
# a SIGHUP signal. If you edit the file on a running system, you have
# to SIGHUP the postmaster for the changes to take effect. You can
# use "pg_ctl reload" to do that.
# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.
# CAUTION: Configuring the system for local "trust" authentication allows
# any local user to connect as any PostgreSQL user, including the database
# superuser. If you do not trust all your local users, use another
# authentication method.
# TYPE DATABASE USER CIDR-ADDRESS METHOD
# "local" is for Unix domain socket connections only
# IPv4 local connections:
# IPv6 local connections:

Uninstalling greenplum performance monitor
1,停止数据库监控程序perfmon，并删除安装文件目录$gpperfmon –stop
$rm -rf /usr/local/greenplum-perfmon-web-4.1.X.X
2,编辑postgresql.conf文件，禁用greenplum的perfmon功能
#su – gpadmin
$vi $MASTER_DATA_DIRECTORY/postgresql.conf
gp_enable_gpperfmon = off
3,编辑gp_hba.conf
# local gpperfmon gpmon md5
