Open Source Linux Systems Administration Software

nmon is short for Nigel's Performance Monitor It either shows you the stats on-screen updating once a second or saves the data to a CSV file for later analysis and graphing. For details see the homepage ==> http://nmon.sourceforge.net Please use the latest version. The new version "njmon" outputs JSON format that a lot of tools use these days. It integrates well with saving data directly to InfluxDB and graphing with Grafana.

Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.

MuninLite is a single Bourne Shell script that implements the Munin protocoll as well as some Linux specific plugins. The motivation for developing MuninLite was to provide a simple Munin Node, using inetd on systems without a full featured Perl.

LDAP Directory Server Monitoring tool with focus on 389 DS / Red Hat / Sun / Oracle ODSEE and Open LDAP. IBM Tivoli and Novell eDirectory. Other Directory Services are also supprted.

Simple command line tool that monitors files and processes and sends notifications or take corrective actions when problems arise. Monitor log files for errors, processes CPU and memory consumption (can kill if exceeding), respawn dead processes.

Big-Brother is a collection of J2EE filters and servlets that provide custom monitoring and auditing of web-applications, keeping track of who does what, when, and how often. It makes use of the jakarta-apache Struts framework for the interface GUI.

Master/node to gather and graph "everything" on your systems using Tobi Oetiker's rrdtool. It can optionally warn your surveillance software. This software package was originally called LRRD. The project. Please see http://munin-monitoring.org/

These tools are for newly released NMON performance analyzer to help gather, collect, store and present via web graphs the data collected. Graphs can be utilized 'on the fly' as data is updated every 10 minutes for support purposes. GET NMON FIRST.

C / Perl based system and network monitoring system (NMS) providing plugin based polling/checking of services, raw and performance data with notifications. Provides full configurable web interface to configure the monitor

Free Java monitoring library to easily instrument apps to measure performance detail over time with minimal overhead. Has dashboard, SVG graphs. Extends Jamon and its statistical data, same usage. http://www.e-peas.com/opensla/. JMX, SNMP planned.

Il s'agit de fournir un programme qui log tous les processus qui tournent ou ont tournés, dans le but d'ętre capable d'établir un systčme de facturation. Pas de Traduction.

SIS is a very simple and portable, system info bash script, work on most GNU/Linux distributions. Tested on Ubuntu and its based distrobution (Eg. Kubuntu), Debian and Fedora. SIS is a tool to help any linux system administrator, to benchmark, test and monitor Linux machines. With a simple UI and easy deployment, you can know most important basic information about the machine you're working on; From installed Drivers, OS & Kernel version, Current Process running etc. SIS is a handy and simple tool to use on most of GNU/Linux Machines.

Voswatcher is a tool to collect time correlated performance data on a Solaris or Linux system. This is a tool to gather data before, during, and after an event. It is a set of scripts which makes it suitable for use with sensitive clients.

Watchdog is a Java performance monitoring and tuning framework. It is suitable for production environments allowing flexible auditing of performance data for later analysis by a comprehensive set of tools.

An open-source Java-based XCCDF reference implementation.

a performance measurement framework and sample tools

The beSee-2-x architecture brings JVM wide instrumentation for AOP systems, independant from bytecode kit (BCEL, Javassist). A plugin is provided to instrument BEA WebLogic (v7) for tracing purpose (servlet->EJB->CMP->DB), with full JMX capabilities.

grabmem -- allocates, initialises, and immediately frees a block of memory. Useful for forcing the OS to flush disk cache and page out programs, if a large amount of free physical memory is needed.

hostscope displays key system metrics of Linux hosts, such as detailed CPU load, speed and temperature, I/O rates of network interfaces, I/O rates of disks, and user process summary information. All metrics are multicast on the LAN, if wanted, and clients can switch between multiple hosts on the network.

This is a simple LDAP benchmark tool. It creates a number of threads and every thread tries to connect to the Server and does a different query x times. Then all the errors and the time are counted. Through this the religability of LDAP should be tested.

sarface is a user-interface to the sysstat/sar database which inputs data from sar and plots to a live X11 graph via gnuplot. It mimics the cmd-line options from sar but can cross-plot any two or more stats and apply simple mathematical functions them.

SRMON stands for System Resource MONitor. Its strength points are: * system resources graphics showed through browser * monitoring of local & remote servers * multiple servers views at a glance * different graphics views * alarms

vtad is a rule-based performance monitoring system for Linux. Intended for servers, vtad monitors your system's performance and makes recommendations for tuning. Custom rulesets can be written for a wide variety of applications.

System monitor is a Java library for monitoring system resources like memory and CPU consumption. The library provides unified cross-platform API for accessing system information. Currently Linux and Windows are supported via Java Native Interface (JNI).
