Cloud hosting provider Joyent re-launched its Node.js hosting service no.de this week. Joyent, the sponsor company of Node.js, is now offering versions 0.4.0 and 0.4.1 to no.de users. It also announced Cloud Analytics, a new service for finding problems with Node.js applications.

According to a blog post by Joyent's Dave Pacheco, Cloud Analytics is a " tool for real-time performance analysis of production systems and applications deployed in the cloud." So far it's only available for Node.js and most of the metrics require version 0.4.0.

Cloud Analytics can monitor:

  • Node.js 0.4.x: HTTP server operations decomposed by method, URL, remote IP, remote port, and latency.
  • Node.js 0.4.x: HTTP client operations decomposed by method, URL, server address, server port, and latency.
  • Node.js 0.4.x: garbage collection operations decomposed by GC type and latency.
  • Node.js 0.4.x: socket operations decomposed by type, remote host and port, size, and buffered data.
  • Filesystem: logical filesystem operations decomposed by pid, application name, zone name (SmartMachine name), operation type, filesystem type, and latency.
  • CPU: thread executions decomposed by pid, application name, zone name, runtime, and reason leaving CPU.

The Node.js hosting space continues to heat up. We've covered other entrant to the field including Nodejitsu, NodeSocket and Nodester. To understand the interest in Node.js, you might want to read our interview with Guillermo Rauch.

Also, Joyent's chief evangelist Tom Hughs-Croucher released a full preview of his book on Node.js today.
