Ganglia – Network Monitoring System
This system is intended for monitoring of both one and numerous services, which are placed both in local and global networks. Ganglia uses RDD tool for information storage and a number of libraries for representation. One of the most features is opportunity to use history logs to get to know about server performance for the last year, month, day, hour. Another brilliant feature is possibility to use different platforms. This packet includes two components:
Modules which collect information are allotted to different servers.
Central concentrator, which accumulates this data (Windows module is absent at present day)
This packet gives an opportunity to use multilevel concentrators, for example if you have 3 segments you can provide each segment with single concentrator, besides you can use central concentrator for this purpose. The system allows data transfer using two protocols Multicast and Unicast.
