Configure a separate log file with customizing file name pattern

dieuph — Thu, 26 Sep 2019 04:23:20 -0400

Based on the answer from:

https://answers.axonivy.com/questions/1852/how-can-i-configure-a-separate-log-file-for-the-runtime-log

And:

https://stackoverflow.com/questions/5117758/configuring-rollingfileappender-in-log4j

I see we could customize the file name of the separated log file by using org.apache.log4j.rolling.RollingFileAppender instead of org.apache.log4j.RollingFileAppender Then I try to add log4j-extras (https://mvnrepository.com/artifact/log4j/apache-log4j-extras/1.2.17) to {engine_dir}/plugins. But it doesn't work.

Do I miss anything?

We use an external elasticsearch and the jvm.options is:

Could anyone give us some hints?

How can I enable HTTP/2.0 support for Ivy Engine

dieuph — Mon, 01 Oct 2018 05:53:38 -0400

Hi all, I try to improve the application performance by using HTTP/2.0. Currently, I'm using Ivy 7 and Nginx 1.10.3.

I make some configuration following https://dev.to/grigorkh/how-to-set-up-nginx-with-http2-support-2mgb , but seems like it's not as my expectation.

Does anyone try to enable HTTP/2.0 for Ivy Engine before?

Thanks.
