Smarts SAM web console to the Smarts broker and domains is slow

Products

• VMware Smart Assurance

Issue/Introduction

After upgrading to Smarts Service Assurance Manager, the initial connection of Smarts SAM Dashboard or Smarts SAM Web Console to the Smarts broker and domains is slow.

 

Environment

SMARTS - 10.1.x

SMARTS DM - 2.x

 

Cause

• The issue has been found to occur when there is a lack of Entropy on the system.
• Entropy is required by the Transport Layer Security (TLS) protocol used by Smarts and a lack of Entropy in the system will cause a delay in establishing a TLS session, resulting in a slow broker/domain connection.
• Smarts Foundation software started using the industry standard TLS protocol as the inter-process communication protocol for Smarts applications.

Resolution

If you encounter this issue, you can do either of the following:

• Disable TLS
• Set the java "egd" parameter on the system where the browser runs

The following sections explain the requirements, considerations, and steps for each of these options. 

• Disabling TLS:

Disabling TLS should be done in accordance with the local network security policies. Disabling TLS can be done as follows:

1. On the machine where the Smarts tomcat server is started, open the webconsole.properties file in the following directory: 
   
   

   <BASEDIR>/smarts/tomcat/webapps/webconsole

2. Add the following line (or set existing parameter to "true"):
   
   

   # Flag to disable TLS
   com.smarts.no_tls=true

3. Save and close the webconsole.properties file.
4. Restart tomcat after this change is made.
