tailor can tarnsport data over the network like fluendtd . It will useful for correct same logs from multiple machine's, e.g. docker containers, Web servers under the load balancing.
Transport some data from CLI, and realtime watch these data on Web UI.
First, execute central-server process at external server that enable to access by browser, (sample is example.com)
$ tailor -C [-d]
If you want to run with daemon, add -d option.
tailor supply the Web Interface at http://example.com:9000 (enable to change listen host/port number with -h/-p option), access http://examole.com:9000 on browser.
Central server accepts data on HTTP interface with CORS. In this sample case, endpoint is http://example.com:9000/remote. then, send data from any client support HTTP interface, curl, XMLHttpRequest, etc....
Second, Execute tail data and transporting process at web servers you want to watch:
$ tailor [-d] -R http://example.com:9000 /var/log/httpd/access_log
If you want to run with daemon, add -d option.
-P option's value is a central server's host:port. Then, tailing data will transport to central server, and can watch Web Interface.
If you stop the daemon, execute with --kill option:
$ tailor --kill
Central server supply GUI on browser, updating realtime logs by WebSocket. You can see logs that classified by host, one, two, four splitted panes.
- Currently we support transport interface only HTTP , not support HTTPS. So that, central/transporting server recommend to be an appropriate settings, with Firewall.
- Transported data does not save anywhere, watiching only.
