正在生成最后隧道报告

本文介绍如何生成Cato最后隧道报告，这些报告由Cato智能隧道监控（ILMM）服务为您的账户创建的最后隧道故事。

概概览

Cato提供了预定义报告模板，总结了Cato ILMM服务为您的账户检测到的所有最后一英里故事的数据。这使您可以生成一份报告，突出显示ILMM服务在组织中相关利益相关者方面的能力。最后一英里链接报告包括生成最多故事的ISP和站点的数据、最后一英里链接故事趋势以及您账户服务的一般信息。

您可以创建定期或一次性的最后一英里链接报告。

有关报告的更多信息，请参见 Cato 报告。

条件

最后一英里链接报告仅适用于ILMM和NOCaaS客户。有关订阅这些服务的更多信息，请联系您的Cato代表。

创建定期最后一英里链接报告

Create a new recurring report by defining the Filters for the items included in the report, as well as the Schedule which defines how often the report is generated - every two minutes, daily, weekly, or monthly. Generated reports are stored in the Cato Cloud, and they can be automatically emailed or downloaded. The Schedule also defines the time range that is covered by each report.

You can select a mailing list of email addresses for the recipients, which can include Cato Management Application admins, and external users.

For more information about Mailing Lists, see Working with Mailing Lists.

To create a recurring report:

From the navigation pane, select Home > Reports.
From the Catalog tab, find and select the template you want to use to generate the report.
Click Generate > Create Schedule.
Enter a Report Name.
(Optional) In Filters, select specific sites or users for the predefined report.
By default, the predefined report includes all sites and users.
Define when the report will be generated and sent:
1. Select the Frequency.
2. For Weekly and Monthly scheduled reports, in Every select the day that the report is sent.
3. Select the timezone.
Select the export format: PDF or CSV.
In Subscriptions, select the Mailing List that receives the report.
You can click New to create a new mailing list.
Click Save Schedule. The report is added to the Saved Reports tab.

Generating a Recurring Report On Demand

Recurring reports are automatically generated based on their schedule settings. For example, a weekly report configured for Monday, is generated every Monday. You can also choose to manually generate a recurring report on demand, in which case the generated report uses the defined time range based on the current day. If an admin manually generates a weekly report on a Tuesday, the time range for the report is the previous 7 days starting from that Tuesday, regardless of the starting day of the recurring report. For more information about the time range of recurring reports, see Cato Reports.

To generate a recurring report on demand:

From the navigation pane, select Home > Reports.
From the Saved Reports tab, find the recurring report and click Generate Now.
From the Generated PDFs tab, find the report and click Download.

创建一次性最后一英里链接报告

您可以基于最后一英里链接报告模板创建一次性报告。您可以为报告中包含的项目定义筛选器。

To create a one-time report:

From the navigation pane, select Home > Reports.
From the Catalog tab, select the template you want to use to generate the report.
Select Generate > Generate Now.
Enter a Report Name.
Define the relevant Filters for your report.
These are specific to the report type.
Define the Timeframe and Timezone of the report.
Select the Format: PDF or CSV.
Click Generate.
The report is generated, and you can download it from the Generated tab.

Downloading Reports

Download your scheduled or one-time reports from the Generated tab. You can use the Reload button to refresh the Generated tab and see if a report is Ready to download. It may take a few minutes to generate reports with large amounts of data. Recurring reports are In Progress when they are automatically emailed. To download recurring reports, generate a new report in the Saved Reports tab and then download it. You can use the Reload button to refresh the reports to see whether it’s Ready to download.

Admins with viewer permissions are allowed to download reports.

To download a report:

From the navigation pane, select Home > Reports.
From the Generated tab, find the report and click Download.
To delete a report, click and select Delete.

理解最后一英里链接报告

最后一英里链接报告的各部分显示了为配置的时间范围的数据。以下是各部分：

ILMM服务 - 一般数据 -
- ILMM站点 - 为您账户中的ILMM服务包括的监控和未监控站点总数。监控站点是至少有一个最后一英里链路进行主动性能监控的站点。未监控站点是正在加入的站点、被请求暂停监控的站点或没有足够ISP信息以积极监控的站点。
- ILMM链接 - 为您账户中的ILMM服务包括的监控和未监控链接总数。监控链接是定期监控最后一英里问题的链接。未监控链接是被请求暂停监控的站点或没有足够ISP信息以积极监控链接并管理与ISP问题的链路。
- 单WAN站点 - 具有单一WAN链接连接的站点数量。单WAN站点缺乏最佳实践的网络弹性。我们强烈建议每个站点拥有多个最后一英里连接。
  注意： 这个数字还包括具有备用WAN连接的站点。
故事摘要
- 拥有最多故事的提供商 - 生成最多最后一英里链接故事的ISP。
- 拥有最多故事的站点 - 生成最多最后一英里链接故事的站点。
- 故事摘要 - 报告期内出现在监控站点的最后一英里链接故事类型的细分。
- 最后一英里链接故事趋势 - 显示生成的报告期内监控站点的聚合故事，按故事类型细分。
最后一英里链接故事 - 针对生成故事的所有监控链接，此表显示报告时间范围的故事总数以及按故事类型（站点中断、链路中断、质量SLA和Alt）细分。 WAN链路中断）。表格按生成的故事数量排序。
- 链路正常运行时间百分比通过将时间范围分成2分钟的桶来衡量，并根据隧道外的最后一英里监控探针确定每个桶是否有最后一英里连接。有关最后一英里监控探针的更多信息，请参见下文。
  注意：正常运行时间仅计算已配置探测器的链接。 Alt. WAN链接不支持探针，默认情况下，最后手段的链接未启用探针。
  一个存储桶按以下标准被视为停机时间：
  - 单个Socket站点 - 如果给定接口的所有隧道外探针在时间段内均未能到达任何目的地
  - 对于HA站点 - 如果两个sockets上相同接口的所有探针在时间段内均未能到达任何目的地
    注意： 这个逻辑假设Cato推荐的HA Sockets对称配置的ISP链接的最佳实践。
  理解最后一英里监控探针 - Cato的最后一英里监控探针功能帮助您监控最后一英里ISP链路的质量。有关启用和配置探针的更多信息，请参见Last Mile Monitoring Probes and Connectivity。您可以在站点网络分析页面（网络 > 站点 > <选定站点> 站点监控 > 网络分析）查看由探针生成的指标。最后一英里监控探针相关的指标是下面显示的最后一英里丢包和最后一英里距离图：
  
  有关这些指标的更多信息，请参见显示站点网络分析。
  注意：
  当Cato隧道中断时，会触发事件。但是，在某些情况下，根本原因不是ISP链接，探针仍可能检测到连接性。因此，可能会在报告中显示某个站点的多个故事，而链接正常运行时间似乎不受影响。
