- nkallen's cachet at master - GitHub
- [Alternativa a Varnish] Cachet is an HTTP Reverse Cache Proxy written in Scala. It is comparable to Varnish or Rack::Cache. It implements the RFC2616 specification (at this time, only the Expiration model, but the Validation model is forthcoming) obeying Cache-Control headers and the like. It is very configurable so that you can use custom databases (Ehcache and Memcached are supported by default), and custom expiry strategies, and so on. It is designed so that you can layer on things like authentication, authorization, rate limiting, and arbitrary service composition strategies (e.g., Edge-Side Includes)--which is is, I think, something novel in an open-source reverse proxy.

- collectl
- There are a number of times in which you find yourself needing performance data. These can include benchmarking, monitoring a system's general heath or trying to determine what your system was doing at some time in the past. Sometimes you just want to know what the system is doing right now. Depending on what you're doing, you often end up using different tools, each designed to for that specific situation. Unlike most monitoring tools that either focus on a small set of statistics, format their output in only one way, run either interatively or as a daemon but not both, collectl tries to do it all. You can choose to monitor any of a broad set of subsystems which currently include buddyinfo, cpu, disk, inodes, infiniband, lustre, memory, network, nfs, processes, quadrics, slabs, sockets and tcp.

- Xen VMs performance collection
- Unlike VMware Server, Xen’s HyperVisor does not allow an easy collection of performance information. The management machine, called “Domain-0″ is actually a privileged virtual machine, and thus - get its own small share of CPUs and RAM. Collecting performance information on it will lead to, well, collecting performance information for a single VM, and not the whole bunch. Local tools, such as “xentop” allows collection of information, however, combining this with Cacti, or any other SNMP-based collection tool is a bit tricky. A great solution is provided by Ian P. Christian in his blog post about Xen monitoring. He has created a Perl script to collect information. I have taken the liberty to fix several minor things with his permission. The modified scripts are presented below.

- collectd - The system statistics collection daemon
- collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD-files.

- Fenxi - Performance Analisys Tool
- We just opensourced a nice performance analysis tool called Fenxi. Fenxi is a pluggable Java-based post-processing, performance analysis tool that parses and loads the data from a variety of tools into a database, and then allows you to query and compare different sets of performance data. Fenxi can also be used to graph data from performance tools. Fenxi (mandarin for analyze) is the successor to the Sun-internal tool called Xanadu. It is integrated with the Faban Benchmark harness.

- Iometer project
- As the Iometer User's Guide says, Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 - since then it got wide spread within the industry.
