For logging the gRPC requests you can use nginx as a reverse proxy. gRPC support was added in version 1.13.10<\/a>.<\/p>\n

To install it locally on your Domino server (RHEL), open a terminal and do the following:<\/p>\n

1. Identify which version you are running<\/h2>\n
cat \/etc\/redhat-release<\/code><\/pre>\n
The resulting output tells you which major version you are using:<\/p>\n
[notes@redhat-dev-hq \/]$ cat \/etc\/redhat-release \r\nRed Hat Enterprise Linux Server release 7.6 (Maipo)<\/code><\/pre>\n
2. Add the nginx repository<\/h2>\n
sudo vi \/etc\/yum.repos.d\/nginx.repo<\/code><\/pre>\n
3. Add the repo data<\/h2>\n
[nginx]\r\nname=nginx repo\r\nbaseurl=http:\/\/nginx.org\/packages\/rhel\/7<\/strong>\/$basearch\/\r\ngpgcheck=0\r\nenabled=1<\/code><\/pre>\n
The „7“ in the base url is the major version from step 1.<\/p>\n
4. Install nginx<\/h2>\n
sudo yum install nginx<\/code><\/pre>\n
5. Create a new config for gRPC<\/h2>\n
sudo vi \/etc\/nginx\/conf.d\/grpc.conf<\/code><\/pre>\n
6. Add the debug log configuration<\/h2>\n
server {\r\n     listen 81 http2;\r\n\r\n     access_log \/var\/log\/nginx\/grpc-access.log main;\r\n     error_log \/var\/log\/nginx\/grpc-debug.log debug;\r\n\r\n     location \/ {\r\n        grpc_pass grpc:\/\/localhost:3002;\r\n     }\r\n}<\/code><\/pre>\n
The reverse proxy is now listening on port 81. You have to change the port in the application configuration. The „error_log<\/em>“ is our debug log, the „access_log<\/em>“ logs just the requests itself.<\/p>\n
If you are new to vim: First you have to press „i<\/em>“ to insert text. After pasting the configuration above, press <ESC><\/em>, then :w<ENTER><\/em>, then :q<ENTER><\/em><\/p>\n
7. Test the configuration<\/h2>\n
[notes@redhat-dev-hq \/]$ sudo nginx -t\r\nnginx: the configuration file \/etc\/nginx\/nginx.conf syntax is ok\r\nnginx: configuration file \/etc\/nginx\/nginx.conf test is successful<\/code><\/pre>\n
8. Start the nginx debug task & enjoy the results<\/h2>\n
sudo service nginx stop\r\nsudo service nginx-debug start<\/code><\/pre>\n
Now the log file is full with the complete debug information about the incoming gRPC request.<\/p>\n","protected":false},"excerpt":{"rendered":"
