Dm1134 logging with Node memory usage #360

Closed sutherlanda closed 1 year ago

sutherlanda commented 1 year ago

This PR adds configurable logging in production.

Two new configuration parameters were added for the back-end:

LOG_DEBUG --> enables debug-level logging in production (per-request) LOG_MEM_USAGE --> enables logging memory usage metrics (also requires debug level logging to be enabeld)

Below is an example of the memory usage logging that will be include with each request log:

[request:2f6aaba1-3382-4f28-9a98-38766ee3c5a4] -> GET /images/wayne.jpg sessionId="anonymous"
[request:2f6aaba1-3382-4f28-9a98-38766ee3c5a4] <- 200 1ms
[request:2f6aaba1-3382-4f28-9a98-38766ee3c5a4] memory usage arrayBuffers="0.74 MB" external="2.38 MB" heapUsed="55.83 MB" heapTotal="85.02 MB" rss="147.23 MB"
[request:516acefb-7879-4b39-a203-e5c05e4841dd] -> GET /fonts/BCSans/BCSans-Bold.woff2 sessionId="anonymous"
[request:516acefb-7879-4b39-a203-e5c05e4841dd] <- 200 0ms
[request:516acefb-7879-4b39-a203-e5c05e4841dd] memory usage arrayBuffers="0.95 MB" external="2.6 MB" heapUsed="55.92 MB" heapTotal="85.02 MB" rss="147.28 MB"
[request:b23f2c52-86f9-42d0-9dfc-b31059ab0ee6] -> GET /fonts/BCSans/BCSans-Regular.woff2 sessionId="anonymous"
[request:b23f2c52-86f9-42d0-9dfc-b31059ab0ee6] <- 200 1ms
[request:b23f2c52-86f9-42d0-9dfc-b31059ab0ee6] memory usage arrayBuffers="1.15 MB" external="2.79 MB" heapUsed="55.99 MB" heapTotal="85.02 MB" rss="147.3 MB"

Here is a good explanation of the memory usage metrics.
