Optimize performance in SolarWinds NTA
Due to the volume of data it collects and processes, SolarWinds NTA constantly makes demands on the resources of both the Orion server and its database.
Maintaining your Orion, SQL and NTA Flow Storage database servers on separate physical machines is a fundamental requirement in scaling the SolarWinds NTA implementation. However, even with this setup, the volume of collected and processed NetFlow data calls for other performance optimizing steps.
Follow the recommendations and steps in these sections to optimize performance of your SolarWinds NTA implementation. Due to differences in network environments, results of these optimizations will vary from installation to installation:
- Configure DNS resolution to resolve IPv4 and IPv6 addresses to DNS hostnames instead of immediately. For more information, see Configure resolving IPv4 and IPv6 addresses to DNS hostnames in SolarWinds NTA.
- Capture only the flows required to represent the top talkers on your network. For more information, see Limit flow collections to top talkers.
- Limit the time period for storing flow data in your database. For more information, see NTA Flow Storage database maintenance.
- If you do not need to store traffic data on unmonitored ports, you can disable data retention for unmonitored ports. For more information, see Configure data retention for flows on unmonitored ports .
