Monitoring items include: CPU, memory, swap space, virtual memory, etc. usage rate, as well as the number of TCP connections, bandwidth, disk IO etc.

Diagnose Unix/Linux problems in real time. Use this performance and diagnostic solution tool to identify overloaded areas and quickly respond to problems so as not to affect users. Obtain real-time data streams from Solaris, AIX, HPUX, and Unix/Linux operating systems (including I/O subsystem, cache, and kernel information). Create thresholds by automatically generating a series of normal baseline activities for each system, and send alerts for impending problems.

Features

• enhances the visibility inside the operating system . View relevant information in real time by showing the processing and components of actual I/O traffic
• Through real-time diagnosis of problem areas (including front-end indicators, cache, disk I/O and transaction statistics) to speed up the problem solving
• audio or image alarm function can detect impending problems, you do not need to make unnecessary guesses, so it helps to improve efficiency
• With the help of powerful in-depth diagnosis and fast problem-solving process, reduces end users downtime and improves work efficiency
• By integrating with Foglight®, improves application performance management solution
