Logzio Golang API client

Sends logs to logz.io over HTTP. It is a low level lib that can to be integrated with other logging libs.

Prerequisites

go 1.x

Installation

$ go get -u github.com/logzio/logzio-go

Logzio golang api client offers two queue implementations that you can use:

Disk queue

Logzio go client uses goleveldb and goqueue as a persistent storage. Every 5 seconds logs are sent to logz.io (if any are available)

In memory queue

You can see the logzio go client queue implementation in inMemoryQueue.go file. The in memory queue is initialized with 500k log count limit and 20mb capacity by default. You can use the SetinMemoryCapacity() and SetlogCountLimit() functions to override default settings.

Quick Start

Disk queue

package main

import (
  "fmt"
  "github.com/logzio/logzio-go"
  "os"
  "time"
)

func main() {
  l, err := logzio.New(
  		"fake-token",
	  logzio.SetDebug(os.Stderr),
	  logzio.SetUrl("http://localhost:12345"),
	  logzio.SetDrainDuration(time.Minute*10),
	  logzio.SetTempDirectory("myQueue"),
	  logzio.SetDrainDiskThreshold(99),
  	) // token is required
  if err != nil {
    panic(err)
  }
  msg := fmt.Sprintf("{ \"%s\": \"%s\"}", "message", time.Now().UnixNano())

  err = l.Send([]byte(msg))
  if err != nil {
     panic(err)
  }

  l.Stop() //logs are buffered on disk. Stop will drain the buffer
}

In memory queue

package main

import (
  "fmt"
  "github.com/logzio/logzio-go"
  "os"
  "time"
)

func main() {
  l, err := logzio.New(
  		"fake-token",
	  logzio.SetDebug(os.Stderr),
	  logzio.SetUrl("http://localhost:12345"),
	  logzio.SetInMemoryQueue(true),
	  logzio.SetinMemoryCapacity(24000000),
	  logzio.SetlogCountLimit(6000000),
  	) // token is required
  if err != nil {
    panic(err)
  }
  msg := fmt.Sprintf("{ \"%s\": \"%s\"}", "message", time.Now().UnixNano())

  err = l.Send([]byte(msg))
  if err != nil {
     panic(err)
  }

  l.Stop() 
}

Usage

  • Set url mode: logzio.New(token, SetUrl(ts.URL))

  • Set drain duration (flush logs on disk): logzio.New(token, SetDrainDuration(time.Hour))

  • Set debug mode: logzio.New(token, SetDebug(os.Stderr))

  • Set queue dir: logzio.New(token, SetSetTempDirectory(os.Stderr))

  • Set the sender to check if it crosses the maximum allowed disk usage: logzio.New(token, SetCheckDiskSpace(true))

  • Set disk queue threshold, once the threshold is crossed the sender will not enqueue the received logs: logzio.New(token, SetDrainDiskThreshold(99))

  • Set the sender to Use in memory queue: logzio.New(token, SetInMemoryQueue(true))

  • Set the sender to Use in memory queue with log count limit and capacity: logzio.New(token, SetInMemoryQueue(true), SetinMemoryCapacity(500), SetlogCountLimit(6000000), )

Data compression

All bulks are compressed with gzip by default to disable compressing initialize the client with SetCompress(false):

  logzio.New(token, SetCompress(false),
  )

Tests

$ go test -v
