ELK集群之grafana（8）

Grafana的安装和读取ES数据
模拟es数据产生sjgtest.py
import time
import datetime
from elasticsearch import Elasticsearch
es = Elasticsearch(['http://elastic:sjgpwd@192.168.238.90:9200', 'http://elastic:sjgpwd@192.168.238.92:9200'])
for i in range(10000):
  curtime=datetime.datetime.utcnow().isoformat()
  body = {"name": "sjg{0}".format(i), "@timestamp": curtime, "sjgcount": i}
  es.index(index='sjg', body=body)
  time.sleep(1)
  print('insert {0}'.format(i))

Kibana创建sjg索引查看

Grafana安装
  yum localinstall grafana-6.7.2-1.x86_64.rpm  -y

启动Grafana
  systemctl restart grafana-server
  访问：端口是3000，默认是admin/admin，密码需要更改

Grafana添加数据源sjges
  url: http://192.168.238.90:9200
  选择基础认证
  索引和时间配置

logstash配置
input {
  beats {
    host => '0.0.0.0'
    port => 5044
  }
}
filter {
  json {
    source => "message"
    remove_field => ["message"]
  }
}
output {
  elasticsearch {
    hosts => ["http://192.168.238.90:9200", "http://192.168.238.92:9200"]
    user => "elastic"
    password => "sjgpwd"
    index => "sjgjson-%{+YYYY.MM.dd}"
  }
}

filebeat配置
filebeat.inputs:
- type: log
  tail_files: true
  backoff: "1s"
  paths:
      - /var/log/nginx/access.json.log

processors:
- drop_fields:
    fields: ["agent","ecs","log","input"]

output:
  logstash:
    hosts: ["192.168.238.90:5044"]
