Given the challenges most of us face today, I would whittle this down to a short list of the following four options that we will review in this post: The Grinder Gatling Tsung JMeter We’ll cover the main features of each tool, show a simple load-test scenario, and display sample reports. At the end, you'll find a comparison matrix to help you decide which tool is best for your project.
What I really like about Graphite is the fact that you can push data to it, instead of using a poller, like Cacti for example. Here is a step-by-step guide on how to install and configure Graphite on Ubuntu Server:
Graphite requires: python2.4 or greater pycairo (with PNG backend support) mod_python django python-ldap (optional - needed for ldap-based webapp authentication) python-memcached (optional - needed for webapp caching, big performance boost) python-sqlite2 (optional - a django-supported database module is required) bitmap and bitmap-fonts required on some systems, notably Red Hat
Graphite is highly scalable real-time graphing system. It is seen as a replacement for more traditional graphing systems such as cacti and munin. To install graphite, first you will need to enable the EPEL repository first. Once enabled pull in the required RPMS. # yum install graphite-web graphite-web-selinux mysql mysql-server MySQL-python
he JConsole graphical user interface is a monitoring tool that complies to the Java Management Extensions (JMX) specification. JConsole uses the extensive instrumentation of the Java Virtual Machine (Java VM) to provide information about the performance and resource consumption of applications running on the Java platform. You can use JConsole to monitor both local applications, namely those running on the same system as JConsole, as well as remote applications, namely those running on other systems.
This is effectively the missing connector between speaking to a JVM via JMX on one end and whatever logging / monitoring / graphing package that you can dream up on the other end. jmxtrans is very powerful tool which uses easily generated JSON (or YAML) based configuration files and then outputs the data in whatever format you desire. It does this with a very efficient engine design that will scale to communicating with thousands of machines from a single jmxtrans instance. The core engine is very solid and there are writers for Graphite, StatsD, Ganglia, cacti/rrdtool, OpenTSDB, text files, and stdout.
OMD - the Open Monitoring Distribution. OMD implements a completely new concept of how to install, maintain and update a monitoring system built on Nagios. OMD avoids the tedious work of manually compiling and integrating Nagios addons while at the same time avoiding the problems of pre-packaged installations coming with your Linux distribution, which are most times outdated and provide no regular updates. OMD bundles Nagios together with many important addons and can easily be installed on every major Linux distribution. We provide prebuilt packages for all enterprise Linux distributions and also for some other, such as Ubuntu.
In this article, we will introduce a list of free and open source monitoring system that is helping you to monitor system resources such as CPU load, the RAM memory usage, network traffic statistics or memory consumption. In this article I’ve listed top 10 web based Linux monitoring tools which can cover almost all aspects of sysadmin’s monitoring tasks.
Grafana is a leading open source application for visualizing large-scale measurement data. It provides a powerful and elegant way to create, share, and explore data and dashboards from your disparate metric databases, either with your team or the world. Grafana is most commonly used for Internet infrastructure and application analytics, but many use it in other domains including industrial sensors, home automation, weather, and process control.
Graphite is a highly scalable real-time graphing system. As a user, you write an application that collects numeric time-series data that you are interested in graphing, and send it to Graphite’s processing backend, carbon, which stores the data in Graphite’s specialized database. The data can then be visualized through graphite’s web interfaces.
