htop and top alternatives

We’ve covered top, atop and indirectly due to it’s popularity as top’s alternative… htop (the last screenshot on this page).  But are there any other htop alternatives worth looking at? This is largely a matter of preference regarding what data is most important to you as it pertains to system health and performance. Although somewhat standard, we all prefer different ways of viewing the same thing.

Since the three aforementioned system monitoring tools can hold their own quite easily, I’ll focus on two htop alternatives which I believe can also hold their own as replacements or at least compliments of top and htop. They are, Glances and nnom.

htop alternative: Glances – system monitoring

Glances - system monitoring tool written in Python

Glances is open-source software to monitor and collect operating system statistics. Glances aims to present the max amount of information, in the minimum amount of space. Glances is a good htop alternative as it can adapt dynamically when displaying system information, depending on the terminal size. Remote monitoring can be done via terminal, Web interface or API (XMLRPC and RESTful). Glances is written in Python and uses the psutil library to get information from your system. Stats can also be exported to external time/value databases.

htop alternative: nmon – Nigel’s performance Monitor

nmon - Nigel's performance Monitor for Linux

nmon is another htop alternative systems administrators tool, for server tuning, benchmarking or viewing detailed system performance information. It outputs data in two ways. Either on screen (command line) or after saving data to a comma separated file for analysis and longer term data capture. Honestly, one screenshot isn’t enough for nmon. Have a look at additional screenshots with explanations.

Even more top and htop alternatives:  net-toolsiptrafcollectl, dstatiostat, sar, saidar and vmstat. Looking for more insight and/or APM tools? Have a look at my 50 Top Server Monitoring & Application Performance Monitoring (APM) Solutions post (includes free and paid solutions).
