将 Mist SLE 和洞察与 API 结合使用
当您使用瞻博网络 Mist 门户监控网络运行时，您可以在问题出现之前深入了解正在发生的情况。您可以从多个角度查看网络：无线、有线、WAN 和其他。此外，您还可以使用瞻博网络 Mist™ 提供的工具排除故障并更正潜在问题。
“监控>服务级别”中的主 Mist 仪表板以服务级别预期 （SLE） 指标的形式显示预测分析和关联引擎 （PACE） 的结果。SLE 利用机器学习和瞻博网络 Mist 云中的 Mist PACE。利用这些资源，SLE 将来自接入点 （AP） 的流遥测转换为近乎实时地代表最终用户网络体验的可视化效果。有关 SLE 的更多信息，请参阅瞻博网络 Mist AI 原生操作指南。
与 Mist GUI 中看到的所有内容一样，SLE 和洞察信息也可从 API 获得。
系统性红斑狼疮 （SLE）
收集特定 SLE 的信息以用于历史报告目的或触发其他自动化可能对您有用。与其他 API 调用一样，您首先确定要从哪个终端节点收集数据。以下是终端节点的 getOrgsSitesSle API GET 请求示例：
GET
/api/v1/orgs/{org_id}/insights/sites-sle
有关更多信息，请参阅 SLE 概述。
见解
洞察提供整个站点、接入点或无线客户端的网络体验概览。这是检查网站时的好起点。
您可以通过向以下见解终端节点之一发出 GET 请求来查找见解信息：
- GetSiteInsightMetrics
- GetSiteInsightMetricsForDevice
- GetSiteInsightMetricsForClient
有关详细信息，请参阅 见解概述。
指标和分类器
瞻博网络 Mist SLE 和洞察端点支持指标和分类器。指标跟踪服务级别是否满足配置的阈值。如果指标不符合阈值，则此故障可能归因于其中一个分类器，以进一步了解故障发生的位置。
SLE 和 Insights 端点通常需要参数 metric 。这是因为，除了原始统计信息或配置之外，Mist 还会公开内部数据分析产生的计算值。Mist 不是在每次添加新的数据分析功能时都创建唯一的 API 函数，而是只公开少数函数，但使用该参数指定 metric 要检索的派生数据值。
若要获取见解指标的列表，可以发出以下 GET 调用：
GET
/api/v1/const/insight_metrics
响应将如下所示：

查看可用 Insight 指标示例的另一种方法是登录 Mist 门户，然后从同一浏览器在新选项卡中打开此链接：
https://api.mist.com/api/v1/const/insight_metrics
使用前面的 GET 调用示例 GET /api/v1/const/insight_metrics，您将在调用结束时添加所需的指标。请参阅下面的示例 GET 调用，了解一些当前支持的指标及其分类器。

计算系统性红斑狼疮百分比
SLE 指标成功率按在选定时间范围内达到阈值的频率的百分比计算。分类器也以百分比计算，但这些值指示它们对父故障的影响。
例如，下面的屏幕截图显示连接时间在 96% 的时间内成功;所有在下午 3：00-4：00 成功连接的客户端都在 4 秒阈值内完成了连接过程。
此指标的成功率 （%） 派生自“指标摘要”API 终结点：
/api/v1/sites/:site_id/sle/site/:site_id/metric/time-to-connect/summary?start=1540591200&end=1540594800
{
“start”: 1540591200,
“end”: 1540594800,
“sle”: {
“x_label”: “seconds”,
“y_label”: “seconds”,
“interval”: 600,
“name”: “time-to-connect”,
“samples”: {
“degraded”: [
0.0,
0.0,
3.0,
0.0,
3.0,
0.0
],
“total”: [
19.0,
14.0,
34.0,
8.0,
20.0,
43.0
]
}
}
}
指标故障率的计算方法是将故障数 （sle.samples.degraded） 除以总数 （sle.samples.total）。然后将其转换为成功率百分比。使用上述 API 响应有效负载，计算将如下所示：
ceil(1-[(0.0+0.0+3.0+0.0+3.0+0.0)/(19.0+14.0+34.0+8.0+20.0+43.0)])*100= ceil(1-[6/138])*100= ceil(1-0.04347826086)*100= ceil(0.95652173914)*100= 0.96*100= =96%

分类器的影响 （%） 派生自相同的“指标摘要”API 终结点：

分类器影响的计算方法是将分类器的失败（分类器[n].samples.degraded）除以所有失败（分类器[].samples.degraded）的总和。然后将其转换为百分比。使用上述 API 响应有效负载，DHCP 的计算如下所示：
ceil([0+0+0+0+1.0+0]/[(0+0+0+0+1.0+0)+(0+0+0+0+0+0)+(0+0+3.0+0+1.0+0)+(0+0+0+0+1.0+0)])*100= ceil(1/[1.0+0+4.0+1.0])*100= ceil(1/6)*100= ceil(0.16666666666)*100= 0.17*100= =17%
监控系统性红斑狼疮
系统性红斑狼疮数据每十分钟更新一次。但是，在此粒度进行监视时，SLE 容易出现波动。因此，建议使用显式开始和结束时间查询 1 小时的间隔，并且每小时仅轮询一次。
