标签：Flume 216.20 监控 192.168 install conf Ganglia ganglia channel
1 Ganglia的安装与部署
1) 安装httpd服务与php
# yum -y install httpd php |
2) 安装其他依赖
# yum -y install rrdtool perl-rrdtool rrdtool-devel
# yum -y install apr-devel |
3) 安装ganglia
# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# yum -y install ganglia-gmetad
# yum -y install ganglia-web
# yum install -y ganglia-gmond |
4) 修改配置文件
文件ganglia.conf：
# vi /etc/httpd/conf.d/ganglia.conf
修改为：
#
# Ganglia monitoring system php web frontend
#
Alias /ganglia /usr/share/ganglia
<Location /ganglia>
Order deny,allow
Deny from all
Allow from all
# Allow from 127.0.0.1
# Allow from ::1
# Allow from .example.com
</Location> |
文件gmetad.conf：
# vi /etc/ganglia/gmetad.conf
修改为：
data_source "linux" 192.168.216.20 |
文件gmond.conf：
# vi /etc/ganglia/gmond.conf
修改为：
cluster {
name = "linux"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
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
host = 192.168.216.20
port = 8649
ttl = 1
}
udp_recv_channel {
# mcast_join = 239.2.11.71
port = 8649
bind = 192.168.216.20
retry_bind = true
# Size of the UDP buffer. If you are handling lots of metrics you really
# should bump it up to e.g. 10MB or even higher.
# buffer = 10485760
} |
文件config：
# vi /etc/selinux/config
修改为：
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted |
尖叫提示：selinux本次生效关闭必须重启，如果此时不想重启，可以临时生效之：
5) 启动ganglia
$ sudo service httpd start
$ sudo service gmetad start
$ sudo service gmond start |
6) 打开网页浏览ganglia页面
尖叫提示：如果完成以上操作依然出现权限不足错误，请修改/var/lib/ganglia目录的权限：
$ sudo chmod -R 777 /var/lib/ganglia |
2 操作Flume测试监控
1) 修改flume-env.sh配置：
JAVA_OPTS="-Dflume.monitoring.type=ganglia
-Dflume.monitoring.hosts=192.168.216.20:8649
-Xms100m
-Xmx200m" |
2) 启动flume任务
$ bin/flume-ng agent \
--conf conf/ \
--name a1 \
--conf-file job/group-job0/flume-telnet.conf \
-Dflume.root.logger==INFO,console \
-Dflume.monitoring.type=ganglia \
-Dflume.monitoring.hosts=192.168.216.20:8649 |
3) 发送数据观察ganglia监测图
样式如图：
图例说明：
字段（图表名称） | 字段含义 |
EventPutAttemptCount | source尝试写入channel的事件总数量 |
EventPutSuccessCount | 成功写入channel且提交的事件总数量 |
EventTakeAttemptCount | sink尝试从channel拉取事件的总数量。这不意味着每次事件都被返回，因为sink拉取的时候channel可能没有任何数据。 |
EventTakeSuccessCount | sink成功读取的事件的总数量 |
StartTime | channel启动的时间（毫秒） |
StopTime | channel停止的时间（毫秒） |
ChannelSize | 目前channel中事件的总数量 |
ChannelFillPercentage | channel占用百分比 |
ChannelCapacity | channel的容量 |
