Ganglia Monitoring System " What is Ganglia?

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency.

How much memory does MySQL Enterprise Monitor?s agent use?

After last week’s post on agents versus agentless monitoring systems, I got a lot of email. One, from a customer whose name I am not permitted to mention, sent me the following action shot (posted with permission):

MySQL Enterprise Monitor Memory Usage

Over half a gigabyte; more than twice what MySQL itself is using. So, that raises an interesting question. How much memory would you say your server’s MySQL Enterprise Monitor agent uses? No bashing allowed, tell the truth. And please post if your agent runs in a small amount of memory, too.

Another thing I’m interested in: what factors contribute to the high memory usage? Under what conditions does it use a lot or a little? What can you expect, generally speaking?

On another note, I think it’s almost unfair not to mention the competition, so I will: I was playing with MONyog 2.6 recently and it started to use a lot of CPU. I think it might be architecture-specific (amd64 Ubuntu) but I can’t be sure. It was using 170% CPU on my dual-core system to monitor 2 instances.

autossh - Automatically restart SSH sessions and tunnels

autossh is a program to start an instance of ssh and monitor it, restarting it as necessary should it die or stop passing traffic. The idea is from rstunnel (Reliable SSH Tunnel), but implemented in C. Connection monitoring is done using a loop of port forwardings. It backs off on the rate of connection attempts when experiencing rapid failures such as connection refused.
