Thank you for creating issues and pull requests!

}If you wish to initialize a InfluxDB Hook with an already initialized InfluxDB client, you can use the NewWithClientInfluxDBHook constructor:
import (
"github.com/Abramovic/logrus_influxdb"
"github.com/Sirupsen/logrus"
client "github.com/influxdata/influxdb/client/v2"
)
func main() {
log := logrus.New()
// In this example we will use the default configurations
config := &logrus_influxdb.Config{
Tags: []string{"tag1", "tag2"}, // use the following tags
}
// Connect to InfluxDB using the standard client.
influxClient, _ := client.NewHTTPClient(client.HTTPConfig{
Addr: "http://localhost:8086",
})
hook, err := logrus_influxdb.NewInfluxDB(config, influxClient)
if err == nil {
log.Hooks.Add(hook)
}
}If you wish to push your logs in syslog format so you can view all logs in the chronograf log viewer.
import (
"time"
"github.com/Sirupsen/logrus"
"github.com/Abramovic/logrus_influxdb"
)
func main() {
log := logrus.New()
config := &logrus_influxdb.Config{
Host: "localhost",
Port: 8086,
Database: "syslog", // set to syslog to view in logviewer
UseHTTPS: false,
Precision: "ns",
Tags: []string{"tag1", "tag2"},
BatchInterval: (5 * time.Second),
BatchCount: 200, // set to "0" to disable batching
Syslog: true, // enable syslog format or not
Facility: "user", // see https://en.wikipedia.org/wiki/Syslog#Facility
FacilityCode: 1, // see https://en.wikipedia.org/wiki/Syslog#Facility
AppName: "cb-scheduler", // app_name to use
Version: "1.0", // version of app
}
/*
Use nil if you want to use the default configurations
hook, err := logrus_influxdb.NewInfluxDB(nil)
*/
hook, err := logrus_influxdb.NewInfluxDB(config)
if err == nil {
log.Hooks.Add(hook)
}
}When passing an empty string for the InfluxDB database name, we default to "logrus" as the database name.
When initializing the hook we attempt to first see if the database exists. If not, then we try to create it for your automagically.
We will insert your message into InfluxDB with the field message so please make sure not to use that name with your Logrus fields or else it will be overwritten.
Some logrus fields have a special meaning in this hook, these are server_name, logger and http_request (taken from Sentry Hook).
server_name(also known as hostname) is the name of the server which is logging the event (hostname.example.com)loggeris the part of the application which is logging the eventhttp_requestis the in-coming request (*http.Request)
