Adlex and Network Physics are set to launch new passive, auto-learning appliances.
With many users leery of agent-based approaches to collecting data, more application performance management providers are focusing on centralized appliances to measure end-to-end response times.
Veteran service delivery management provider Adlex Inc., of Marlboro, Mass., this week will launch a new version of its IT service management appliance that provides service-level metrics based on real user experience. Meanwhile, rival Network Physics Inc. is readying a distributed version of its NP-2000 appliance that provides an enterprisewide view of application traffic.
Joining the handful of appliance-based providers will be Peakstone Corp. with the launch next month of its first appliance.
The Adlex ITvisibility appliance provides real-time analysis of usage, availability and performance for applications running across public and private networks. ITvisibility measures response times for IP-based applications as well as for Web applications.
ITvisibility can be used to locate troublesome infrastructure elements and speed fault isolation.
The passive listening device, which connects to the span port on a data center switch behind the corporate firewall, also understands session-level activity and can calculate usage, response time and availability. That data is passed to a central database for analysis.
ITvisibility, which includes the appliance as well as a report server, is available now.
Such passive, auto-learning appliances are gaining ground in the market because they are easier to deploy and administer than agent-based collection, experts say. They provide insight into real user experience, which synthetic transaction testing cant provide.
Reducing time to isolate problems.
