Issue with worker_connections limits in Nginx+
Hello Nginx Community, We are using Nginx+ for our Load Balancer and have encountered a problem where the current worker_connections limit is insufficient. I need our monitoring system to check the current value of worker_connections for each Nginx worker process to ensure that the active worker_connections are below the maximum allowed. The main issue is that I cannot determine the current number of connections for each Nginx worker process. In my test configuration, I set worker_connections to 28 (which is a small value used only for easily reproducing the issue). With 32 worker processes, the total capacity should be 32 * 28 = 896 connections. Using the /api/9/connections endpoint, we can see the total number of active connections: { "accepted": 2062055, "dropped": 4568, "active": 9, "idle": 28 } Despite the relatively low number of active connections, the log file continually reports that worker_connections are insufficient. Additionally, as of Nginx+ R30, there is an endpoint providing per-worker connection statistics (accepted, dropped, active, and idle connections, total and current requests). However, the reported values for active connections are much lower than 28: $ curl -s http://<some_ip>/api/9/workers | jq | grep active "active": 2, "active": 0, "active": 1, "active": 2, "active": 1, "active": 1, "active": 0, "active": 0, "active": 3, "active": 0, "active": 0, "active": 0, "active": 2, "active": 2, "active": 0, "active": 1, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 0, "active": 2, "active": 1, "active": 2, "active": 1, "active": 0, "active": 1, "active": 0, "active": 0, "active": 1, Could you please help us understand why the active connections are reported as lower than the limit, yet we receive logs indicating that worker_connections are not enough? Thank you for your assistance.

F5-NGINX licensing
Hi All, I have a little confused about the NGINX Plus license as well as the F5 license. Could you please help me make it easier to understand? - For hardware, F5 may extend 90 days from the ship date, right? - We can specify the start date as we want when making an order, or the start date will start automatically when we receive a license or service agreement for software, right? So my questions are: - How do I know the ship date, is the start date on the service agreement or the date it was issued the service agreement letter? - Can I activate the software license earlier than the start date that I was specified before? Thanks!
