Ganglia Installation and configuration

A ganglia monitoring is installed for Ceph, as follows.

1. Environmental statement

Ceph is the 3 physical machines installed on the centos6.5: Mon0, OSD1, OSD2, so you need to install Gmond on all three machines, OSD2 on Gmetad.

2. Installation process

Install the Epel source first:

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

To install a dependency package:

Yum Install Apr-devel Expat-devel

Install Gmond in Mon0 and OSD1:

Yum Install  ganglia ganglia-gmond httpd php Apr apr-util

To install Gmetad on OSD2:

Yum Install  ganglia Ganglia-gmetad ganglia-gmond ganglia-web httpd php Apr apr-util

3. Configuration

To configure the Web:

Mkdir-p/var/www/html/ganglia/   //Create a ganglia folder under the home directory to access Gangliacp-a/usr/share/ganglia/*/var/www/html/ ganglia/   //Copy Ganglia website code to this directory chkconfig gmond onchkconfig Gmetad onchkconfig httpd on

The owner of the default /var/lib/ganglia/rrds is ganglia, do not have to be like the internet said to be renamed nobody.

The /var/www/html/ganglia/conf.php may not be valid and requires a manual copy:

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

You may also encounter Web Access forbidden on centos6.5, and you need to modify the/etc/httpd/conf.d/ganglia.conf:

Alias/ganglia/usr/share/ganglia  <Location/ganglia>    Order deny,allow    deny from all    to All   //modify to all to allow from    :: 1    # example.com  </Location>

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".  Gmond used to only support have   a single channel */udp_send_channel {  host = 192.168.108.4   //gmetad ip
   port = 8649}/* You can specify as many udp_recv_channels as a well. */udp_recv_channel {  port = 8649  bind = 192.168.108.3   //natively IP  family = inet4}

Configuration/etc/ganglia/gmetad.conf, just modify one line here:

Data_source "Ceph" 192.168.108.4:8649//gmetad IP

Start the various services, and then you can see the monitoring interface in the Web input gmetad_ip/ganglia.

The above is a unicast configuration, there is a multicast configuration, you can query.
