Linux System Monitoring Tools Every SysAdmin Should Know | Part II
Nload is a command line tool which is mainly used to monitors the network throughput. Output of this tool can be seen in using two graphs, one for incoming and one for outgoing network.
yum install nload
sudo apt-get install nload
collectd is a daemon which collects system and application performance metrics periodically. This tool gathers metrics from various sources which can be used to monitor systems and find the possible bottlenecks.
CPUlimit is a small tool which monitors and then limits the CPU usage of a process. CPUlimit can be used to prevent a process from running for more than a specified time ratio.
stat is a builtin tool which is used for displaying various information of files and file systems. We can get the the information like file modification date, access date and changed date too.
Webmin is a web-based system administration tool. You can easily setup users account, DNS, Apache, File sharing and many more job through web browser.
MultiTail allows you to monitor logfiles and command output in multiple windows in a terminal. It uses colors to display the logfiles which makes it easy to read for users.

Logwatch is a customizable log analysis system.It parses through system’s logs and creates a report analyzing areas that you specify.
mpstat is a built-in tool for cpu usage monitoring. mpstat can also get an interval update of the CPU usage for you.
Justniffer is a network protocol analyzer. It captures network traffic and produces logs. It gives you the option to choose whether to collect low-level data or high-level data with this sniffer.
TCPdump is a powerful command-line packet analyzer.

Darkstat captures network traffic, calculates statistics about usage, and serves reports over HTTP.
- Traffic graphs, reports per host, shows ports for each host.
- Embedded web-server with deflate compression.
- Asynchronous reverse DNS resolution using a child process.
- Small. Portable. Single-threaded. Efficient.
- Supports IPv6.
Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring the health and welfare of network equipment (eg. routers), computer equipment and even devices like UPSs. Net-SNMP is a suite of applications used to implement SNMP v1, SNMP v2c and SNMP v3 using both IPv4 and IPv6.
SmokePing can be used to track of network latency. It is loaded with plenty of features like,Interactive graph explorer, Wide range of latency measurement plugins, Live Latency Charts with the most ‘interesting’ graphs and many more.
Shinken is a monitoring framework. It is a Nagios compatible monitoring framework, written in Python and can be used to monitor your servers and applications.
