SpectroSERVER Performance Administration

In highly dynamic IT environments, monitoring the capacity of your systems and optimizing your 
DX NetOps Spectrum
 deployment cannot be a one-time task. Regular, periodic reviews are required to keep 
DX NetOps Spectrum
 operating optimally in larger environments (more than 1,000 monitored devices). For a well-developed, up-to-date summary of the performance and tuning best practices that we have derived from years of testing and supporting 
DX NetOps Spectrum
, be sure to read , which is available on the Documentation Bookshelf.
 
DX NetOps Spectrum
 also provides self-monitoring. The OneClick client application lets Network Administrators monitor and troubleshoot a 
DX NetOps Spectrum
-managed network. The Performance tab in the OneClick interface supports most network and device models. You can use this tab to analyze the CPU and memory utilization of a specific device.
For the VNM model that represents a 
SpectroSERVER
, we also include a robust application to monitor performance. Performance View lets 
DX NetOps Spectrum
 administrators monitor the performance and system resource utilization of a 
SpectroSERVER
. Use Performance View to identify performance problems and to determine the appropriate corrective actions to take. Your user account requires Performance Monitor privileges to deploy Performance View.
System Component Monitoring
Each computer system comprises four major components: disk, network, memory, and CPU. To ensure the successful operation of your 
DX NetOps Spectrum
 system, you can tune one or more of these components to eliminate bottlenecks.
Performance View includes the following two features to help you detect and locate bottlenecks:
  • A series of tabs that provide information about the system components and 
    SpectroSERVER
     activities that can affect performance. Check the Main tab for overall system and network activity at a glance.
  • A health report feature that lets you run a report on the 
    SpectroSERVER
     resources over a 24-hour period.
 In a distributed 
SpectroSERVER
 environment, you can switch the focus of Performance View from one 
SpectroSERVER
 to another.
For more information, see Getting Started with Performance View and Overview of the User Interface sections.
Performance Data Analysis
Often, the information in Performance View identifies the source of a performance problem. For instance, the CPU tab lists the 10 processes that are currently using the highest percentages of CPU time. However, exactly what constitutes a problem or bottleneck depends on the specific configuration of your 
DX NetOps Spectrum
 system and your network management priorities.
For guidelines on identifying performance problems and corrective actions, see Evaluating the Performance of a SpectroSERVER. You can also run a health report, which includes analysis of the performance data. For more information, see Running Health Reports .
