gLogCollector

This is a simple tool to collect and forward logs. When finished it should be able to efficiently read new logs written in any given folder and then forward these logs via a gRPC connection.

Usage

The executable has two parameters:

• --log-folders: specify folders to read logs from. The folders need to exist! Default is ./logs,./log
• --grpc-addresses: specify the backends to send logs to. Seperate multiple servers with , e.g. localhost:8080,example.web.com:234. Default is none
• --grpc-port: specify the port of the gRPC server to start. If none is set no server will be started. Default is none

The log files need to be appended to via software or in the editor. Most modern IDEs and editors will perform two write operations on save, which results in the entire file being logged even if only one line changes!

To start the application as server for a specific port:

Windows:

logging.exe --log-folders . --grpc-port 8080

Linux:

./logging --log-folders . --grpc-port 8080

you can then connect a client that sends logs in folder ./logs to the server:

Windows:

logging.exe --log-folders ./logs --grpc-addresses 127.0.0.1:8080

Linux:

./logging --log-folders ./logs --grpc-addresses 127.0.0.1:8080

Generate from Protobuf file

To generate the gRPC code you need to download and install the Google Protocol Buffer Compiler.

Afterwars you have to install the following go packages:

go get -u google.golang.org/grpc
go get -u github.com/golang/protobuf/protoc-gen-go

Finally you can regenerate the [communication/log.pb.go] file using

Linux:

protoc -I communication/ communication/log.proto --go_out=plugins=grpc:communication

Windows:

protoc -I .\communication\ .\communication\log.proto --go_out=plugins=grpc:communication
