Installation

Pre-Requirements.

• ElasticSearch
• Redis

Installing

Installing LogVoyage is as easy as installing any other go package:

go get github.com/firstrow/logvoyage
logvoyage create_users_index

Usage

Once you installed LogVoyage you need to start backend and web servers.

logvoyage start-all

Or you can start/stop servers separately

logvoyage backend
logvoyage web

Once server started you can access it at http://localhost:3000. Execute logvoyage help for more info about available commands.

Sending data to storage

By default LogVoyage opens two backend ports accesible to the outsise world.

1. 27077 - TCP port
2. 27078 - HTTP port

Telnet

NOTE: Keep in mind to change `API_KEY` and `LOG_TYPE`.
You can find your api key at http://localhost:3000/profile page.

telnet 127.0.0.1 27077
API_KEY@LOG_TYPE {"message": "login", "user_id": 1}
API_KEY@LOG_TYPE simple text message

Now you can see your messages at http://localhost:3000 and try some queries

Curl

Or we can use curl POST request to send messages. Each message should be separated by new line.

echo 'This is simple text message' | curl -d @- http://localhost:27078/bulk\?apiKey\=API_KEY\&type\=LOG_TYPE
echo '{"message": "JSON format also supported", "action":"test"}' | curl -d @- http://localhost:27078/bulk\?apiKey\=API_KEY\&type\=LOG_TYPE

Search data

Refer to Query String Syntax for more info about text queries available.

Examples:

user_id:1
simple*
amount:>10 and status:completed
