Tomcat log warnings for connection parameter limits?

[Baron Fujimoto]

I'm investigating occasional 503 errors for our CAS service running in a
Tomcat 10.1.x container. The 503s appear to correlate with some traffic
spikes at the same time.

The connector is configured as follows:



Can Tomcat log info such as when the maxThreads or maxConnections limits
are reached? I'm basically trying to see if there is a good way to
more definitively determine what may have caused the 503s and what may be
feasible to mitigate them.

Retrieve server.built, server.number

[prat 007]

Hi All,

I would like to know is there a way to find tomcat's server.built and
server.number remotely using tool loke curl or from browser?

I am currently running tomcat v 9.0.87.

This information gets displayed when we run version.sh or in the starting
logs when tomcat starts up but how we can find it without logging into the
tomcat server.

Thanks,

Re: Tomcat & Http 103 Early Hint

Hi Mark,

Is there any chance I could help with delivering this new feature? At
least, I can help with writing some tests.

I think this new http feature can be beneficial a lot for web application
page load performance. Therefore, this is crucial for the whole Tomcat
community.
