Install an additional polling engine, additional web server, or high availability server
Use the SolarWinds Installer to install scalability engines (additional polling engines, additional web servers, and high availability backup servers).
Additional polling engines (APEs) or an additional web server (AWS) can be used to increase the monitoring capacity of your Orion Platform products. High availability (HA) provides a backup server to protect your main SolarWinds Platform server.
- To learn more about the SolarWinds Installer, see the Orion Platform Products Installation and Upgrade Guide.
- For more information about options to scale your SolarWinds implementation, see Scalability Engine Guidelines for Orion Platform products.
- For details about implementing High Availability, see the full HA documentation.
- License stacking does not require installing a scalability engine. License stacking increases polling capacity by assigning multiple licenses to a polling engine.
Requirements and recommendations
Before you begin, be sure your scalability engine servers meet the following requirements:
Installing an APE and an AWS on the same host is not supported.
All APEs must be set to the same time zone as the SolarWinds Platform database server.
If APEs and the SolarWinds Platform database server are set to different time zones, polled data can be confusing or misleading. For example, data can have a time stamp that is in the future.
The main polling engine and the APE must be able to resolve each other's host names to an IP address.
Orion Platform 2017.3 HF3 or later is required to install scalability engines with the SolarWinds Installer.
To determine the Orion Platform version, log in to the SolarWinds Platform Web Console and find the Orion Platform version in the footer. If the version is between 2016.2 and 2017.3 HF2, use the legacy Orion Scalability Engine Installer.
SolarWinds recommends using the online installer to install scalability engines, even if the server does not have access to the Internet. Internet access is not required. When you install a scalability engine, the installer downloads the required product information from your primary SolarWinds Platform server.
Before you install a scalability engine in your environment, complete the following actions:
|Install or upgrade the primary SolarWinds Platform server first. Then install each APE.|
When you install an APE or AWS, verify the port requirements:
|If you are going to install a backup server for High Availability, review the SolarWinds High Availability requirements.|
|Acquire a user name and password with administrative privileges to the SolarWinds Platform Web Console on your primary SolarWinds Platform server.|
|Be sure the APE uses the same SolarWinds Platform database as the primary SolarWinds Platform server.|
|Verify the latency between your SolarWinds Platform database server and the APE. Performance degradation can begin around 200 ms. Ping the SolarWinds Platform database server to find the current latency.|
|If you configured an alert with a Send Email action to trigger on a node monitored by an APE, confirm that the APE can access your SMTP server.|
Add the IP address of your APE to Windows Servers on the Security tab.
Make sure that the following options are set:
