"We're the only people that get both the internal view and the external view of the application," Anderson said. Diagnostics can be performed on non-Java and non-.Net systems such as PHP (Hypertext Preprocessor) or Apache applications.

AppVision typically competes with either homegrown applications or with application performance monitors from vendors such as Wily Technology and Mercury Interactive, Anderson said.

Wily, however, recently was acquired (http://www.infoworld.com/article/06/01/05/73610_HNcabuyswily_1.html) by CA.

"[AppVision is] definitely a good product in that space and it's one of the rare remaining independent products because the leader in this space, Wily Technology, has been snatched by [CA]," said Jean-Pierre Garbani, vice president of Forrester Research.

Shipping now, AppVision Version 5.0 starts at US$2,495 per server. AppVision previously was known as AppVision-CA (Continuous Availability).
