This article mainly introduces "the installation and configuration steps of ganglia". In the daily operation, I believe many people have doubts about the installation and configuration steps of ganglia. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "installation and configuration steps of ganglia". Next, please follow the editor to study!

A ganglia monitor is installed for ceph, as follows.

1. Environment description

Ceph is three physical machines installed on centos6.5: mon0, osd1, and osd2, so you need to install gmond; on all three machines and install gmetad on osd2.

two。 Installation process

Install the epel source first:

Rpm-ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Install the dependency package:

Yum install apr-devel expat-devel

Install gmond in mon0 and osd1:

Yum install ganglia ganglia-gmond httpd php apr apr-util

Install gmetad on osd2:

Yum install ganglia ganglia-gmetad ganglia-gmond ganglia-web httpd php apr apr-util3. Configuration

Configure web:

Mkdir-p / var/www/html/ganglia/ create the ganglia folder under the home directory of the website, which is used to access gangliacp-a / usr/share/ganglia/* / var/www/html/ganglia/ copy the ganglia website code to this directory chkconfig gmond onchkconfig gmetad onchkconfig httpd on

The owner of the default / var/lib/ganglia/rrds is ganglia, and it doesn't have to be renamed nobody as it is said on the Internet.

The conf.php under / var/www/html/ganglia/ may not be valid. You need to make a manual copy:

Cp / usr/share/ganglia/conf.php / var/www/html/ganglia

You may also encounter a situation where web accesses forbidden on centos6.5. You need to modify / etc/httpd/conf.d/ganglia.conf:

Modify Alias / ganglia / usr/share/ganglia Order deny,allow Deny from all Allow from all / / to all Allow from:: 1 # Allow from .example.com

Configuration / etc/ganglia/gmond.conf:

Cluster {name = "ceph" / / cluster name owner = "unspecified" latlong = "unspecified" url = "unspecified"} / * The host section describes attributes of the host, like the location * / host {location = "unspecified"} / * Feel free to specify as many udp_send_channels as you like. Gmond used to only support having a single channel * / udp_send_channel {host = 192.168.108.4 / / gmetad ip port = 8649} / * You can specify as many udp_recv_channels as you like as well. * / udp_recv_channel {port = 8649 bind = 192.168.108.3 / / Native ip family = inet4}

Configure / etc/ganglia/gmetad.conf, here you only need to modify one line:

Data_source "ceph" 192.168.108.4 data_source 8649 / / gmetad ip

Start various services, and then type gmetad_ip/ganglia in web to see the monitoring interface.

The above is the configuration of unicast and multicast, which can be queried by yourself.
