Distributed monitoring system Ganglia

1. overview
ganglia is a Scalable Distributed Monitoring System . It is based on hierarchical design and widely used in a variety of mature technologies, such as:
1. XML: Data identifier,
2. xdl (external data representation): XDR provides an architecture-independent representation of data, solving the differences in Data byte sorting, Data byte size, data representation, and data ing. XDR applications Program can exchange data on heterogeneous hardware systems
3. rrdtool (Round Robin): data storage and data visualization. Rrdtool refers to the round robin database tool (ring database ).
ganglia uses a well-designed data structure and algorithm to achieve low concurrency between each node. It has been transplanted to a wide range of operating systems and processor architectures and is currently in use in thousands of clusters around the world. It has been used to link university campuses and around the world and can handle 2000 nodes.
ganglia support:
Linux (i386, x86_64, IA64, iSCSI, Alpha, PowerPC, m68k, MIPS, arm, hppa, s390), FreeBSD, NetBSD, OpenBSD, dragonflybsd, MacOS X, Solaris, Aix, Irix, Tru64, HPUX and Windows NT/XP/2000/2003/2008/

2. Components
Ganglia includes the following components:
1). ganglia monitoring daemon (gmond): multi-thread daemon running on the cluster node to be monitored.
2). ganglia meta daemon (gmetad): collects the data of each cluster and updates it to the RRD database.
3). ganglia PHP Web frontend: provides dynamic Web display of collected information.

3. install and use Ubuntu
1) Make sure that Apache and PHP are installed. If not, refer:

There is only one grid, and the grid has only one node. Adding a node to the grid is simple. You only need to specify the name of the cluster to be added and the multicast address of the cluster in the/etc/ganglia/gmond. conf file of the node.
