The feature 9 of the Best Free Linux System Monitoring Tools, written in July 2009, highlighted our personal picks in open source monitoring software at that time. However, there has been significant developments since that article was published.
We have witnessed other applications which have stepped up to the mark, offering high quality solutions for monitoring services, services and network hardware. The purpose of this article is therefore to identify these applications omitted from the original article, all of which are also definitely worth evaluating.
To provide an insight into the quality of software available for Linux, we have compiled a list of 6 more of the best free monitoring tools. Hopefully, there will be something of interest here for anyone who needs to monitor servers, devices, and ensure that a computing system maintains high performance. We give our highest recommendation to Zabbix.
