Session limit for REST API

 

Hello Experts,

 

Is there any limit to the number of sessions for NSO Northbound REST API?

 

I know we don't hit the limit in the real world, but my customer would like to confirm. Any comments would be appreciated.

 

Best regards,

Hiro

As usual with NSO, there are no hard limits. At some point the system would run out of memory, file descriptors, ... etc of course. For reasonable numbers of "sessions", any increase in load will just lead to longer response times.

 

In the ncs.conf file, it is possible to configure a limit on the number of REST API "sessions", as well as a limit on the total northbound sessions.

Hello Jan,

Thank you so much for your comments.

 

I understand there is no hard limits. I will use ncs.conf when necessary.

 

Thanks again.

 

Best regards,
