SaaS startup Paglo has added monitoring for Amazon's cloud to its IT search and management service.Paglo, an InformationWeek Startup 50 company, announced a new application to monitor Amazon EC2 application instances. The application uses Amazon's CloudWatch API in conjunction with a Ruby-based Paglo plug-in to deliver statistics on utilization and performance of applications running on EC2, including disk reads and writes, CPU utilization and network traffic.

Paglo has been on a new-features roll. In May, the company announced support for monitoring VMware-based virtual machines. Paglo can gather information from VM hosts including configuration data, the amount of virtual disk being used, and which apps and users are using the VM.

Paglo's technology revolves around the Paglo Crawler, software that customers install on their networks. The crawler discovers assets including servers, desktops and network devices, and reports information, such as configuration data, up to a database in Paglo's data center.

Administrators access the information from a Web browser. In addition to monitoring and alerting, administrators can search the database and run queries against it, using either natural language queries or Paglo's own SQL-like language.

The Paglo service costs $1 per device per month.
