# flsend
|
||||
|
||||
Simple tool to send message to fluent
|
||||
|
||||
## Building
|
||||
|
||||
|
||||
```sh
|
||||
go install go.ar76.eu/arek/flsend@latest
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Parameters:
|
||||
|
||||
```
|
||||
Usage of flsend:
|
||||
-host string
|
||||
Fluentd address (default "localhost")
|
||||
-port int
|
||||
Fluentd port (default 24224)
|
||||
-prefix string
|
||||
Tag preffix (application name) (default "flsend")
|
||||
-tag string
|
||||
Message tag (required)
|
||||
```
|
||||
|
||||
Message is read from the standard input and send to fluentd with tag composed of{prefix}.{tag}.
|
||||
|
||||
Eg.
|
||||
|
||||
```sh
|
||||
echo '{"msg": "Message description"}' | flsend -host 10.10.10.10 -tag test
|
||||
```
|
||||
|
||||
saves the message in fluentd as
|
||||
|
||||
```
|
||||
2023-03-14T16:10:54+00:00 flsend.test {"msg":"Message description"}
|
||||
```
