Monitoring Bandwidth Usage for a Xen node @ IONCANNON

After my last post on limiting bandwidth usage on a Xen node I thought I would follow up with how to monitor the bandwidth usage of a Xen node. I chose to use netacct-mysql to monitor bandwidth and store the results into a mysql database. This isn't the only way of monitoring the bandwidth but it was easy to set up and stores the information directly into mysql without needing any extra scripts. On the Xen setup I'm using for an example there are 3 nodes and a bucket for each node will be created in the mysql database by netacct. Setting up netacct can be tricky so you will want to check to make sure traffic for each node is going into the correct bucket.

Supervisor - Home

by 4 others
Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems. It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as "process id 1". Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.

Create Disk Usage Reports with durep -- Ubuntu Geek

urep is a perl script used for disk usage reports. It can generate text output with bar graphs to allow easy comparisons of disk usage between directories. It can also generate web pages which can be navigated through the directory structure. This allows easy visual monitoring of disk usage. durep was designed for monitoring disk usage in a more visual way than du. The du program works fine but doesn’t allow a lot of control over how the results are displayed. This perl script is designed to produce output more useful for reports.

Monitoring File Uploads using Ajax and PHP - PHP articles and tutorials, MySQL, PostgreSQL

by 1 other
Because of the limitations of HTTP, it is difficult to monitor the status of files as they are uploaded via HTML forms. While other programming languages have built-in methods to monitor file uploads, PHP does not. This article shows how to implement such a solution in PHP. In order to achieve this, the APC (Alternative PHP Cache) PHP extension is required, as well as PHP 5. Specifically, APC 3.0.13 or newer and PHP 5.2 or newer are required for the code in this article to work. We will cover installation of APC in the next section. It is assumed you already have a working PHP 5.2 installation.

MySQL Performance Monitoring Tool by Quest Software

by 1 other
Spotlight® on MySQL diagnoses MySQL problems in real time by graphically displaying all database activity in an intuitive user interface, enabling you to respond quickly to issues that need attention. With Spotlight on MySQL, DBAs or developers running Windows can drill down to locate in-depth information on the source of a performance issue. And because the run-time nature of your MySQL databases is unique, Spotlight calibrates itself to a baseline of normal database activity. This allows Spotlight to automatically establish the speed of the internal flows and other activity indicators. When a threshold is met, Spotlight notifies you using a visual or audible alert. Spotlight on MySQL supports MySQL versions 5.0 or later that employ the InnoDB storage engine.

NagiosVMA - VMTN Virtual Appliances

NagiosVMA is virtual machine appliance that runs Nagios, a powerful, open-source application which performs host, service and network monitoring. Additionally, the appliance was enhanced with Groundwork Monitor Architect, an open-source, web-based, configuration tool for Nagios. It is intended to offer the end-user sophisticated network monitoring in minutes, instead of hours, (or even days) as is typical with building and configuring a Linux/Nagios host. Using Nagios combined with Monarch and Monarch's automatic host discovery feature, this virtual machine appliance can be booted, configured, and ready to monitor your network in as little as 10 minutes. (in fact, as soon as it boots, its already monitoring this virtual machine appliance!)
