Performance Optimization

You can typically resolve 
SpectroSERVER
 performance problems by tuning the 
SpectroSERVER
 to improve server performance. You can also add 
SpectroSERVER
s to distribute the network load. The following topics discuss these options.
 
SpectroSERVER
 Tuning
Once you have identified the reasons for degraded performance, you can tune the 
SpectroSERVER
 to optimize performance. Tuning can include taking any of the following measures:
  • Modifying the polling interval and the poll-to-log ratio of essential device models and application models, and disabling polling of non-essential models. Increasing the polling interval reduces the network traffic. As a result, latency, which degrades performance, can be reduced.
  • Increasing the capacity of the system by increasing memory, CPU speed, or disks.
  • Reducing the number of traps that are mapped to 
    DX NetOps Spectrum
     events.
  • Reducing the amount of data that is requested by customized watches and displayed attributes. Performance improves if you can reduce the amount of data that is requested from the 
    SpectroSERVER
     and devices.
  • Adjusting the usage of features such as Live Pipes, Discovery, and automatic device configuration.
  • Adjusting client interactions with the 
    SpectroSERVER
    . For example, reports that are generated using 
    Spectrum Report Manager
     can exert a punctuated or prolonged performance burden on the server. The performance impact depends on the data that is reported and on reporting frequency. Command Line Interface (CLI) scripts, manual discoveries, and other manually initiated tasks can also affect 
    SpectroSERVER
     performance.
Additional 
SpectroSERVER
s
To determine whether increasing the number of 
SpectroSERVER
s, rather than tuning, is the best means of achieving desired performance improvements, you can request a sizing of your 
DX NetOps Spectrum
 environment from CA Support. The sizing tool uses information about your network configuration to estimate the following:
  • The additional network management traffic that 
    DX NetOps Spectrum
     generates.
  • The number and configuration of additional 
    SpectroSERVER
    s that are required to efficiently manage the number of models in your environment.
