How to know if my nginx is in good health?

I am running a nginx on EC2 (m1.small) for SSL termination.
I am using 2 workers on Ubuntu, with latest nginx (stable), the network
throughput is around *2Mbps* and system load average is around *2 to 3.*
I am wondering if this system is in good health for now,
1. what is the queue length (I know nginx can handle a lot of concurrent
request, but I mean before the request is being served, how many of them
need to wait before being served)
2. what is the average queue time for a given request to be served.
I want to know because if my nginx is *cpu bounded* (e.g. due to SSL), I
will need to upgrade to a faster instance.
My current nginx status
Active connections: 4076
server accepts handled requests
90664283 90664283 104117012
