10 Free Server & Network Monitoring Tools that Kick Ass
By Ben Dowling When you have a website or a network, it’s helpful to be aware of any issues as soon as they occur. There are open source and freeware server/network monitoring tools that will supervise your infrastructure for any issues that may arise. These tools are meant to aid you in avoiding being taken offline and evaluating if your resource needs has outgrown your infrastructure. In this article, we review our top 10 server/network monitoring tools. 1. Monit not only monitors your server, but also attempts to remedy problems by taking predefined actions for certain situations. If you have more than one server that you need to monitor, then you can use M/Monit– an extended version of Monit that provides a simple way to monitor multiple machines. There’s also an iPhone app available for M/Monit to help you conveniently check on your network without lugging around a laptop around. 2. When you have a cluster of machines, it’s difficult to see how the whole cluster is doing all at once. Related:  Open Source Monitoring ToolsDevOps Tools

Vendor Landscape for Application-Aware Network Performance Monitoring and Network Packet Brokers Vendor Landscape for Application-Aware NPM and NPB Solutions Expands The vendor landscape for application-aware NPM and NPB solutions continues to expand, with acquisitions, consolidation and innovation in the monitoring space. These market movements prompt a closer look at the solutions, especially given the ever-increasing upgrade cycles of network bandwidth. These technologies allow visibility and monitoring of network-centric applications, end-user experience and network-based application tracing, and an understanding of the infrastructure components used to deliver an application. Networks have always been perceived as a focal point of blame for application performance issues. What once was simple packet capture and analysis has evolved into a much more sophisticated set of IT products that encompasses traffic management, network monitoring and unprecedented user-experience visibility from a nonintrusive network perspective.

Руководство ответственного за устранение инцидентов в Win2k Корректные действия по устранению последствий инцидентов в компьютерной безопасности стоят на втором месте по важности, уступая лишь превентивным мерам по предотвращению этих инцидентов. Неправильная обработка, или сбор имеющейся информации может нанести непоправимый вред исследованию. Исследователи должны хорошо знать, какую информацию они намерены собирать, а также какие инструменты они могут использовать, и какое влияние окажут эти инструменты на саму систему. Михаил Разумов , по материалам SecurityFocus Вступление Исследователи знают, что не каждое событие требует полного исследования. В этой статье используются термины «исследователь» и «ответственный за устранение инцидента». Шаг 1: Защита «временной информации» («Volatile Information») Когда говорят о «компьютерной экспертизе» («computer forensics»), на ум приходят картины выключения (shut down) компьютера и побитное копирование жесткого диска.

How can I remotely monitor the free disk space on an PHP enabled server with PRTG? | Paessler Knowledgebase This article applies to PRTG Network Monitor 7 or later This article explains how to monitor the free disk space on a remote web server that supports PHP scripts. If your webserver is located outside of your LAN it is usually not possible to monitor the free disk space using SNMP or Windows System Sensors due to firewall and security restrictions. Using the small PHP script "PHP probe" below you can monitor the free diskspace on your remote web server using the "HTTP Content" sensor of PRTG Network Monitor. This sensor type requests a HTTP URL and parses the resulting HTML code for "[xx]" and uses the "xx" as the value for the sensor. Copy the script below into a folder of your web server that is configured to run PHP scripts (e.g. In the URL, replace the "drive" value C: with the according value: In the URL, replace myuser and mypass by the values you entered in the script.

Devops corner, épisode 1 : Chef pour les nuls Cet article est le premier d’une longue (enfin je l’espère) série d’articles visant à partager des retours d’expériences autour de Devops, issus de travaux internes ou de missions chez divers clients. Ils sont aussi l’occasion de détailler un peu plus la session que j’ai présenté récemment à Devoxx France : déploiement d’environnements complets dans le Cloud, en utilisant Rackspace, Capistrano et Chef. Cette session présentait un système de déploiement automatisé, d’une plateforme complète (applications, infra réseau, monitoring), sur le cloud (AWS, Rackspace ou OpenStack) pour Fasterize. Les gains apportés par un tel système sont importants : Pouvoir toutes les nuits redéployer des environnements from scratch et lancer des tests de non régression, qui couvrent à la fois le déploiement et le fonctionnelQuasiment plus d’opérations manuelles sur les serveursUne grande facilité à faire évoluer l’architectureScalabilité : ajouter des noeuds en une ligne de commande Chef, c’est quoi ? Go !
