NagVis

by lecyborg & 2 others
NagVis is a visualization addon for the well known network managment system Nagios. NagVis can be used to visualize Nagios Data, e.g. to display IT processes like a mail system or a network infrastructure. Key features are: * Display of single Hosts and Services * Visualize a complete Host- oder Servicegroup with one icon * Display the state of a Host dependent on the state of its services (“recognize services”) * Display only the real problems (“only_hard_states”) * Define Sub-Map icons wich represent a complete NagVis Map of Hosts/Services/Groups in one icon (drill down) * Visualization/Documentation of complete IT Processes and Infrastructures using self drawn graphics

Using Nagios to Monitor Networks

by lecyborg
Nagios is a powerful, modular network monitoring system that can be used to monitor many network services like smtp, http and dns on remote hosts. It also has support for snmp to allow you to check things like processor loads on routers and servers. I couldn't begin to cover all of the things that nagios can do in this article, so I'll just cover the basics to get you up and running.

Munin, une alternative simple à Cacti?

by lecyborg & 1 other
Cela fait près d’un an et demi que j’utilise le logiciel Cacti pour monitorer l’activité réseau. Aussi bien dans le cadre de mon activité professionnelle que pour mon usage personnel. Mais j’ai récement découvert une alternative sérieuse : Munin. Celui-ci présente de nombreux avantages par rapport à Cacti et mérite d’être plus connue.

Munin

by lecyborg & 6 others
Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources.

ctail project page

by lecyborg
ctail is like running tail -f, but can be used on multiple files. It uses the Curses library to split the screen into as many windows as there are files to watch. The size of each file's window can optionally be specified on the command line. Regular expressions can be used to display only lines matching (or not matching) arbitrary criteria. Each file's window has a status bar, showing the file name, date and time of last change and current file size.

How-To: Monitor your servers with SNMP and Cacti

by camel & 1 other
SNMP (Simple Network Management Protocol) is a protocol for managing networks. Each managed entity in the network will run an snmp server (snmpd) which is going to collect datas from the server such as networking, load, cpu ... Cacti on the other hand is a frontend to the RRDTool with SNMP support. It collects and keep data in a MySQL database and display them through a PHP web frontend.

Lapsus

by camel & 1 other (via)
Lapsus is a set of programs created to help manage additional laptop features. It currently supports most features provided by asus-laptop kernel module from ACPI4Asus project, such as additional LEDs, hotkeys, backlight control etc. It also has experimental support for IBM laptops features provided by IBM ThinkPad ACPI Extras Driver. It consist of a daemon program monitoring ACPI events, reading/writing system files created by either asus-laptop or ibm-acpi module and run commands that need privileged access. The daemon can be controlled over DBus using the client program, or any other programs which has support for that, or can be customized to do so. It can also be controlled with dbus-send utility.
