Ever since system administrators have been in charge of managing servers and groups of machines, tools like monitoring applications have been their best friends. You will probably be familiar with tools like, and Centreon.
While those are the heavyweights of monitoring, setting them up and fully taking advantage of their features may be somewhat difficult for new users.In this article we will introduce you to Ganglia, a monitoring system that is easily scalable and allows to view a wide variety of system metrics of Linux servers and clusters (plus graphs) in real time. Ganglia Mobile Friendly Summary View SummaryIn this article we have introduced Ganglia, a powerful and scalable monitoring solution for grids and clusters of servers.
Feel free to install, explore, and play around with Ganglia as much as you like (by the way, you can even try out Ganglia in a demo provided in the project’s.While you’re at it, you will also discover that several well-known companies both in the IT world or not use Ganglia. There are plenty of good reasons for that besides the ones we have shared in this article, with easiness of use and graphs along with stats (it’s nice to put a face to the name, isn’t it?) probably being at the top.But don’t just take our word for it, try it out yourself and don’t hesitate to drop us a line using the comment form below if you have any questions.
June 24, 2014. At Velocity 2014, Fastly engineer Vladimir Vuksan gave an intro to Ganglia concepts (grid, clusters, hosts) as well as an installation of a sample monitoring grid.
He also goes through the following commonly used visualization tools and how they may aid in detecting issues, identifying causes, and taking corrective action:- Cluster/Grid Views- Aggregate graphs- Compare Hosts- Custom graph functionality- Views- Interactive graphs- Trending- Nagios/Alerting system integration- How to add metrics to Ganglia- Different export formats such as JSON, CSV, and XML.
