Recently, we are using Grafana to show the data of elastic search. Next, I will use elastic search as the data source in Grafana to draw the IO diagram of the network and the IO diagram of the disk

• System: centos7.x, ip: A

Installing grafana

$ yum install https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.6.3-1.x86_64.rpm

Add grafana server to system boot entry and boot:

$ systemctl enable grafana-server.service
$ systemctl daemon-reload //#Reload systemd and scan for new or changed units
$ systemctl start grafana-server
$ systemctl status grafana-server

Then enter in the browser: http://A:3000, both user and password are admin

es correlation

• es related operations are all operated in kibnan

1. New index and mapping in es:

PUT /test?pretty   //New index
POST test/test_type/_mapping   //Add mapping, where there must be a field of type date
{
    "test_type": {
            "properties": {
                "appId": {
                    "type": "keyword"
                },
                "createTime": {
                    "type": "date"
                },
                "detail": {
                    "type": "keyword"
                },
                "ip": {
                    "type": "keyword"
                },
                "level": {
                    "type": "keyword"
                },
                "module": {
                    "type": "keyword"
                },
                "tag": {
                    "type": "keyword"
                },
                "threadName": {
                    "type": "keyword"
                },
                "type": {
                    "type": "keyword"
                }
            }
        }
}

1. Insert data into:

PUT test/test_type/1
{
    "createTime": "2019-05-09T11:58:41+0800",
    "ip": "2345332",
    "appId": "11000000",
    "threadName": "Thrad-acceptor-2",
    "level": "error",
    "type": "eror",
    "tag": "ta1",
    "module": "mdule1",
    "detail": "soe description"
}

The date type here, because the default date in es is utc time, because the difference between utc and Beijing time is 8 hours. If only time is inserted here, Then it will be displayed in 8 hours . Therefore, it is necessary to change utc time to Beijing time. The insertion above is after the change.

grafana interface configuration
