Logship

Simple CLI tool for fetching file data or log entries from remote host.

Build from source

$ go get github.com/iobestar/logship/cmd/logship

Note: It is recommended to have GO111MODULE=on to ensure the correct dependencies are used.

Server

Logship in server mode serves file data in form of log units. Log unit identifies
group of files based on glob pattern. Log unit is defined with id and glob pattern.

Configuration file (logship.yml):

log_units:
  - id: service_error
    glob: /var/log/myservice/error.log*
  - id: service_output
    glob: /var/log/myservice/outout.log*

Run logship server:

$ logship server --address=":11034" --logunits="myservice_error:/var/log/myservice/error.log*:myservice_output:/var/log/myservice/output.log*"

Run as logship server as Docker:

$ docker run --name=logship -p 11034:11034 -v "/var/log/myservice":"/var/log/myservice" -e LOGSHIP_CONFIG="<logship.yml>" -d iobestar/logship
