Tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress HTTP, WebDAV, PostgreSQL, MySQL, LDAP, AMQP, and XMPP/Jabber servers. It simulates user behavior using an XML description file, reports many measurements in real time (statistics can be customized with transactions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET, POST, PUT, and DELETE methods, cookies, and basic/digest authentication. It also has support for SSL, WebSocket, and BOSH.
The ATA over Ethernet Tools are intended for use in conjunction with an ATA over Ethernet (AoE) driver for a Linux 2.6 kernel, called "aoe". The tools perform simple tasks like listing available devices, triggering device discovery, and restricting the network interfaces on which AoE is performed.
Jagger is a Java application monitoring tool that uses JMX technology to aggregate, archive, and visualize monitoring data for larger computer clusters, giving developers and administrators both a succinct and comprehensive view into their systems. Normal JMX consoles cannot do this due to information overflow.
PeaceMaker is a failover/clustering engine system based on a message passing protocol system over TCP/IP between two or more nodes. It can monitor node faults based on interface polling status, health sanity node status, and messages passed through an external plugin attached to a plugin module. Node faults or state change events can be handled through external programs or TCP/IP notification.
Myosotis allows MySQL and PostgreSQL clients to connect directly to the Sequoia cluster or any other database with a JDBC connector. From the client application's point of view, Myosotis acts as a MySQL or a PostgreSQL server. It's like a proxy, and it sits between the client and the database server.
DynaStop is a utility to examine IPv4 based addresses for Exim and procmail for the purpose of filtering based upon patterns defined by the administrator. This can be a pivotal factor in email filtering and server load management, since dynamic IP addresses are typically used for dial-up, DHCP, and DSL accounts. All of which have a designated mail exchange server through which all outbound mail flows as defined with many, if not most, large Internet service providers.
JumboMem gives unmodified binaries transparent access to memory spread across multiple computers. The goal is to improve the performance of memory-hungry applications by replacing accesses to a slow paging device (a disk) with accesses to fast RAM located across a high-speed network. Unlike other memory servers, JumboMem does not need administrator privileges either to install or run.
PMS/PyPubSub (short for Python Message Service / Python based Publish Subscribe) is a framework for implementing a publish subscribe mechanism into a Python application. A python process somewhere in the network publishes one or more topics which consist of Python objects. Multiple processes in the network can subscribe to fresh updates of the published topics. A publisher and its subsribers are fully decoupled. The datatype of a topic can be freely defined and changed at runtime. New publishers and subscribers can easily be added at runtime.
