This SAS KB article describes the initial data capture to collect for troubleshooting when SAS Visual Investigator pages are slow to load while running on SAS Viya 3.5. Collecting troubleshooting data when you initially open a case expedites time to resolution by enabling SAS Technical Support to provide informed problem analysis.
Collect Data
I. Initial Questions
- What is the current version and hot fix level of your environment? (To locate this information, log on ► click your user icon in the top right corner ► select About.)
- In what type of environment does the issue occur? (That is, PROD, DEV, TEST, STAGE, and so on.)
- What specific page loads slowly? Do the SAS Visual Investigator Admin pages load slowly?
- How long does it take to load the page? What is the expected time to load the page?
- Provide any additional details that can be shared regarding the business impact of this issue.
II. Data Collection
Share the following data collection with SAS Technical Support:
- On each microservices machine, enable NMON by running the following command:
cd /opt/sas
sudo nmon -f -T -s 30 -c 1440 &
This command does the following:
-
-
- runs nmon once every 30 seconds for a total of 12 hours (adjust the syntax as needed.)
- creates a file approximately 10MB in size in the /opt/sas directory
Note: Allow nmon to run to completion. That is, do not stop the process.
- Enable a HAR capture. Log on to the environment and reproduce the page loading issue. See SAS KB0036430, "Using the web browser developer tools to investigate issues in SAS® Web Applications" for more information.
- Capture the following information:
- the browser URL
- the starting time request
- the completed time request
- Capture logs from each of the Microservices machines:
- /var/log/httpd
- /opt/sas/viya/config/var/log/svi-datahub
- /opt/sas/viya/config/var/log/svi-visual-investigator
