Skywalking 8是如何启用自定义Dashboard并持久化，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

添加大屏视图：

这里手动添加的这个Dashboard并没有持久化到后端存储里，而是全部保存到浏览器本地缓存，????

添加完成后，导出json。如下内容：

[{
	"name": "SLA Overview",
	"type": "metric",
	"children": [{
		"name": "Overview",
		"children": [{
			"width": 3,
			"title": "Service Summary",
			"height": 350,
			"entityType": "All",
			"independentSelector": true,
			"metricType": "REGULAR_VALUE",
			"metricName": "service_sla",
			"queryMetricType": "readMetricsValue",
			"chartType": "ChartNum",
			"aggregation": "/",
			"aggregationNum": "100",
			"unit": "%"
		}, {
			"width": "9",
			"title": "Service Overview",
			"height": "1000",
			"entityType": "Service",
			"independentSelector": true,
			"metricType": "REGULAR_VALUE",
			"metricName": "service_sla",
			"queryMetricType": "sortMetrics",
			"chartType": "ChartSlow",
			"topN": "100",
			"sortOrder": "ASC",
			"unit": "%",
			"aggregation": "/",
			"aggregationNum": "100"
		}]
	}]
}]

持久化操作

目前我用的是elasticsearch7， 修改oap server里config/ui-initialized-templates.yml

在最后一行添加：

  - name: SLA Overview
    configuration: |-
     [
     {"name":"SLA Overview","type":"metric","children":[{"name":"Overview","children":[{"width":3,"title":"Service Summary","height":350,"entityType":"All","independentSelector":true,"metricType":"REGULAR_VALUE","metricName":"service_sla","queryMetricType":"readMetricsValue","chartType":"ChartNum","aggregation":"/","aggregationNum":"100","unit":"%"},{"width":"9","title":"Service Overview","height":"1000","entityType":"Service","independentSelector":true,"metricType":"REGULAR_VALUE","metricName":"service_sla","queryMetricType":"sortMetrics","chartType":"ChartSlow","topN":"100","sortOrder":"ASC","unit":"%","aggregation":"/","aggregationNum":"100"}]}]}]
    activated: true
    disabled: false

添加完成后重启oap server，oap server会将这些配置持久化到elasticsearch 7里了。我们可以通过kibana查询具体索引：
