ganglia 组建全网grid of Grids思路

官网关于组建的方法很少，而在部分网站已经实现了远程grid集群组网（例如：）

昨晚之后的效果与上面链接的情况一致！

先将组建远程Grid网络总结和遇到的一些问题发给大家,仅供参考：

配置概述：

1、全网（最高级别显示）

gmetad.conf参数

#grep -v ‘#’ /etc/ganglia/gmetad.conf

data_source "clusterGrid" 50 10.10.218.60:8651 //*指定采集的数据源地址和XML端口号*

setuid_username "root" //*验证数据目录属性*

gridname "Top Grid" //*指定最顶层gridname属性*

rrd_rootdir "/var/lib/ganglia/rrds" //*指定rrds存储目录*

authority ""  //*指定集群访问本地ganglia链接地址，必须有*

scalable on //*开启收集下游转发服务器功能*

gmond.condf请参数gmond客户端设置

gweb设置为默认，未改动

2、采集汇总服务器

#grep -v ‘#’ /etc/ganglia/gmetad.conf

data_source "SY" 50 127.0.0.1:8649 //*指定采集的数据源*

setuid_username "root"

gridname " clusterGrid "

rrd_rootdir "/var/lib/ganglia/rrds/"

authority ""  //*指定集群访问本地ganglia链接地址，gweb需要用到*

trusted_hosts 127.0.0.1 10.10.218.225 10.10.218.60 //*指定信任XML共享服务器，可以不实用次操作*

all_trusted on

xml_port 8651 //*指定XML应答所用端口号*

gmond.condf请参数gmond客户端设置

3、采集服务器（此处忽略未作设置）

可以没有gmetad，如果需要设置参考上文采集汇总服务器的gmetad设置

开启gmond采集功能，修改gmond.conf中的beaf=on，其他请参考gmond客户端设置

4、gmond客户端

只开启gmond客户端

globals {

daemonize = yes

setuid = yes

user = nobody

debug_level = 0

max_udp_msg_len = 1472

mute = no

deaf = yes

allow_extra_data = yes

host_dmax = 0 /*secs */

host_tmax = 20 /*secs */

cleanup_threshold = 300 /*secs */

gexec = no

send_metadata_interval = 0 /*secs */

}

/*

* The cluster attributes specified will be used as part of the

* tag that will wrap all hosts collected by this instance.

*/

cluster {

name = "SY"

owner = "clusterGrid"

latlong = "unspecified"

url = "unspecified "

}

/* The host section describes attributes of the host, like the location */

host {

location = "BeiJing_DBL"

}

udp_send_channel {

bind_hostname = yes # Highly recommended, soon to be default.

# This option tells gmond to use a source address

# that resolves to the machine's hostname. Without

# this, the metrics may appear to come from any

# interface and the DNS names associated with

# those IPs will be used to create the RRDs.

#mcast_join = 239.2.11.71

port = 8649

host = 10.10.218.60

#ttl = 1

}

总结：

根据现有配置在gweb发布页面中有Grid名为“ Borqs_Panguso”的远程Grid数据源，实际情况未出现改Grid数据源。

问题总结：

在全网服务器gweb没有显示改grid，gmetad中的debug未报错，rrds中也没有该数据；采集服务器的gmetad也没报错

gmetad启动的debug信息：

[root@VM-0001 ~]# service gmetad restart

Shutting down GANGLIA gmetad: [FAILED]

Starting GANGLIA gmetad: Going to run as user root

总结分析结果，应为功能以实现。具体情况应该是版本问题！事后证明，果然为版本问题所致
