In any event, if anyone wants to discuss any of these point in more detail I’ll be happy to elaborate on any/all of them. So, we have come up with some Linux system and network monitoring tools, providing complete observability, from open-source and freemium to enterprise-ready solutions.Let’s take a look at them: Log Tail. Not as pretty, but it always tells the truth. As you all know that monitoring your Linux system plays a crucial role. This is fine for rough trends but not for deeper analysis – that’s why I use gnuplot. If you want accuracy for diagnostic purposes and use RRD, you may be surprised to know it does not plot your data faithfully but rather normalizes it. Then there is visualization, which you need if you have a lot of data to look at. I’m talking about monitoring at 1-10 second intervals and not generating a load of more that 1% even at a 1 second sampling rate. If you’re only collecting data at a rate of a minute or so you may not have the granularity to see what’s really going on. I think one of the overriding questions to all of this is WHY are people monitoring? Is it to get a general sense of their system’s health OR collect enough data to be able to diagnose a future problem, because I believe the 2 are not the same.įor example, if you’re collecting data over the network and the network dies, you may not be able to get the very data you need to diagnose it. There are lot of plugins available for Munin, which will just work out-of-the box without lot of tweaking. The primary emphasis of Munin is on the plug and play architecture for it’s plugin. Similar to Cacti, Munin uses RRDTool to present the output in a pretty graph via web interface.

Developed by: Zabbix SIA (Private company).Zabbix has the following three main modules: You can choose any DB of your choice – MySQL, PostgreSQL, Oracle, or SQLite. Zabbix requires a database to store the monitoring data. Zabbiz is an open source monitoring solution with a commercial support provided by a company – Zabbix SIA, who primarily develops the software. The main difference is that you can use mouse to interact with the htop command output. htop (interactive process viewer for Linux) – htop is similar to top command with few additional features.Apart from the command line, you can also launch the web version of the ntop once you’ve started the ntopd service and visit from browser. You can also create HTML output file (dump) of the network status using ntop. ntop displays network usage information in a similar fashion to top command output.

ntop (Network Top) – Ntop is a free network monitoring software.

Top Command – Few of you have mentioned top command as your favorite monitoring tool 🙂.

Some admins like the powerful graphing feature provided by Cacti, they use both Nagios and Cacti in their environment as the network monitoring tools. Using Caci you can monitor and graph – CPU Load, Network bandwidth utilization, network traffic monitor etc.,Ĭacti also supports plugin architecture. Cacti – Network Monitoring SoftwareĬacti uses RRDtool for the network graphing solution.

Nagios Core 3 eBook is the only guide you’ll ever need to monitor everything, be proactive, and sleep well.
