• Do not use basic auth while sending RestAPI requests to director. Use OAuth instead of basic auth.
  • Do not call live-status API to get status from all VOS devices via director. Instead stream alarms and events from Analytics to your collector which will be sent in key-value format and consume that data build your monitoring tool. Live API status may not give all the status changes happened in between. To give an example, if interface flapped and came back in 2 seconds but APIs are made every 5 seconds once to get interface status, interface flap alarm is missed.
  • Limit monitor APIs to lesser than 50 APIs/second to director.
  • If you do not follow Versa recommended sizing for directors like not disabling hyperthread, not configuring 1:1 CPU pinning etc(refer versa headend sizing document for recommendations), director user experience might suffer.
  • Versa recommend to use streaming alarms and events from analytics to your collector and use that data instead of any pull models like API calls to director or SNMP walk.
  • Reach out to Versa account and sales team if you need any help.
