The Health Inspector is an extremely lightweight application that sends an email notification, at a customizable interval, which documents: •Any test class failures•Confirmation of test classes running longer than a configurable second count•The overall code coverage of the environment and whether it is below a user defined threshold •Flow code coverageLastly it documents the long running Apex Classes & Methods which can be used not only as a reference but also as a baseline for future executions.The Health Inspector app not only notifies a defined set of users but it can also generate a file which contains the results of the execution so you can monitor your results over time or refer back to any previous executions.The application was designed to be administered with simple configuration updates, rather than via code, and can be completely managed via the Salesforce setup menu.Page | 3Page | 4Health Inspector InstallationThe Health Inspector package can be installed from the following AppExchange listing:https:///appxListingDetail?listingId=a0N3A00000FMkhsUAD During the installation process, leave all selected defaults and install for Administrators only. Health Inspector AppAfter installing Health Inspector, you will be able to select the Health Inspector app from the App Launcher:There are two tabs by default in this app – ‘Health Inspector Results ’ & ‘Files ’.Health Inspector ResultsThe Health Inspector Results tab is designed to be the “one stop shop” for managing the application. This screen provides information relevant to:• The last execution of the Health Inspector app (pass or fail)• The resulting status of the last execution• Easy way to view all available configurations• Quick links to manage all configurations or edit individually• Ability to run a one-off execution of a configuration• Quick access to any files generated from executionsPage | 5FilesThis is the native Salesforce Files tab. If you have set Health Inspector to generate files on success/failure, you will be able to see those records on this tab.Health Inspector ConfigurationUpon installation of the Health Inspector application, one Custom Metadata Type record is created: •Test Class Audit Parameter (Test_Class_Audit_Parameters__mdt)Additionally, there is one Custom Setting that can be configured to store details around the last execution of the application:•Global Settings (Global_Settings__c)Below is a summary of the Custom Metadata Type & Custom Setting and how they are used in conjunction with the application.Test Class Audit Parameter (Test_Class_Audit_Parameters__mdt)The ‘Test Class Audit Parameter’ Custom Metadata Type (CMDT) is used to drive the core functionality of the Health Inspector application. Within this CMDT, the following can be configured: •Cadence of the app’s execution•Recipients of the email notifications•Code coverage tolerance amount•Contents of the success & failure email alerts•Code coverage running user•Generation of success or failure File creationUpon installation of the application, two entries will be created: ‘Default’& ‘DefaultWithFlow’. The difference between these two are that the ‘DefaultWithFlow’ entry contains language in the template to support the Flow Code Coverage functionality. Whereas the ‘Default’ entry has language specific to standard code coverage – not including flow. These entries are fully customizable so they can be modified to your exact use case. There is also the option of creating a new entry to support your individual requirements.To create a new or update the existing CMDT entries, na vigate to the Setup menu and type in ‘Custom Metadata Types’ in the search box and select that from the menu. In the resulting screen, find the ‘Test Class Audit Parameter’custom metadata type and click the ‘Manage Records’ link next to it:From the resulting screen, to create a new entry click the New button or to edit one of the existing, click the Edit link to the left of the ‘Default’ or ‘DefaultWithFlow’ entry. For most organizations, one of the Default entries should be used, as it contains the HTML for both the Health Inspector success and failure email templates. For users who are comfortable with HTML, you can feel free to create a new CMDT record and create your own email content.Page | 6Page | 7In the next screen, the following field should be populated based on your requirements:•Information Section o Label - (Required )▪ Enter an intuitive name for the Health Inspector entryo Test Class Audit Parameter Name – (Required )▪ This will default based on the Label value that was provided▪ Note: you will need this value to schedule the Health Inspector in a subsequentstepo Duration Tolerance (seconds)▪ This should be the number of seconds the test should run – for example, if thetest runs longer than X seconds, include it in the notification▪ For reference, 10 seconds is usually a baseline that can be used to determine ifthere is a long running classo Email Distribution▪ Enter the email address or addresses (comma delimited) that should receive theHealth Inspector email resultso Ignore Errors▪ Enter any errors that should be ignored by the Health Inspector logic.

In the resulting screen, click on the Manage link to the left of the ‘Global Settings’ entry:Next, click on the ‘New’ button at the top of the screen. Do not click the ‘New’ button found right above the list view as these two buttons result in varying setups.After clicking ‘New’, you will be brought to a screen that shows a ‘Last Run Date/Time’ field and a ‘Last Run Status’ field. You can leave both fields null and just click the ‘Save’ button.Page | 13As you finalize the Health Inspector setup and the app runs, the values from your execution will write back to this Custom Setting. In doing so, those values will then be shown on the ‘Health Inspector Results’ tab found within the application.Scheduling Health InspectorCreate Custom Class to ScheduleIn order to schedule the Health Inspector application to run on a custom CMDT entry: •Go to the Developer Console → File → New → Apex Class•Enter a name for the classo For example, if you’re CMDT entry is called ‘MyTest’, then perhaps give it a name of ‘HealthInspector_MyTest’•Click OK•Overwrite the default class text with the following:*The “HealthInspector_MyTest’ value should be replaced with the name you gave the class in the second step**The “Default” value in the above snippet should be replaced with the name of the CMDT that was configured as part of the setup process.Create ScheduleTo schedule the ‘Default’or ‘DefaultWithFlow’ entry:•Go to the Salesforce Setup menu•Search for ‘Apex Classes’ in the left-hand navigation and select it•Click on the ‘Schedule Apex’ button•From the resulting screen, enter the following information:o Job Name = <Enter intuitive name for the schedule>Page | 14o Class Name▪If you are using the ‘Default’ CMDT, then se lectHealthInspectorScheduler_Default▪Else, if you are using the ‘DefaultWithFlow’ CMDT, then selectHealthInspectorScheduler_DefaultWithFlow▪Otherwise, you’ll want to select the class that was defined/deployed in the ‘Create Custom Class to Schedule’ section.o Select the appropriate frequency for executiono Click SavePage | 15Additional Configuration OptionsThere are a few additional configuration options available in the Health Inspector application – executing the batch manually, implementing an extension class and re-running the last test that was generated.Executing Batch ManuallyIn some instances, you may want to manually execute the Health Inspector app to verify your configuration before putting it on a scheduled frequency. In order to do this, simply go to the Developer Console → Debug → Open Execute Anonymous Window and paste the following:*The “CMDT Name” value in the above snippet should be replaced with the name of the CMDT that was configured as part of the setup steps.Implement Extension ClassIn some instances, you may want to take the data collected by the Health Inspector application and use that in a secondary process. The application allows you to do this by referencing an Extension Class which is configured in the Test Class Audit Parameter CMDT. The Extension Class should reference the processResults method to return this information. For example:*The “SAMPLE DEBUG” value in the above snippet can be replaced with any debug information that should be written out at the time of its executionPage | 16Re-Run Last Test GeneratedIn some instances, you may want to re-rerun the last test that was generated. In order to do this, you can simply run the following snippet via the Developer Console:*The “Default” value in the above snippet should be replaced with the name of the CMDT that was configured as part of the setup process.Page | 17Best PracticesIn some cases, you may find that the Health Inspector executions result in a ‘UNABLE_TO_LOCK_ROW’ error which is caused by tests attempting to run in parallel and ultimately caused by record contention between more than one test. To alleviate this issue, follow the steps found at the following link under the ‘Best Practices for Parallel Test Execution’ section:•https:///docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_best_practices.htmPage | 18。

如何在Docker中实现容器的健康检查
如何在Docker中实现容器的健康检查在当前快速发展的云计算和容器技术领域，Docker作为最流行的容器化解决方案，已成为软件开发和部署的首选。
然而，对于任何运行中的应用程序而言，如何保证其持续可用性和健康状态自然是一个重要问题。
在Docker中实现容器的健康检查，成为了容器管理的关键环节。
容器的健康检查可以通过多种方式实现，本文将探讨几种常见和有效的方法。
1. 内置的健康检查功能Docker自身提供了内置的健康检查功能，通过在Dockerfile中添加HEALTHCHECK指令，可以自定义容器的健康检查逻辑。
例如，在一个Web应用容器中，可以通过在Dockerfile中添加HEALTHCHECK指令，来检查HTTP服务的可用性。
通过指定检查间隔和超时时间等参数，Docker将周期性地执行指定的命令或脚本，以检查容器健康状态。
如果命令执行成功，返回值为0，表示容器健康；否则，返回非零值，表示容器不健康。
2. 使用第三方工具除了Docker自带的健康检查功能外，还可以使用一些第三方工具来实现更加复杂和灵活的健康检查。
例如，Prometheus是一种流行的监控和告警工具，它可以通过HTTP接口来检查容器的健康状态。
通过在容器内置一个轻量级的Prometheus 客户端，可以提供更加灵活的健康检查功能。
此外，还有一些专门用于容器健康检查的开源工具，例如Consul、Nagios等，它们可以提供更加细粒度和全面的健康检查方案。
3. 结合容器编排工具在大规模容器集群的管理中，使用容器编排工具如Kubernetes可以更方便地实现容器的健康检查。
Kubernetes提供了灵活而丰富的健康检查配置选项，包括使用HTTP请求、TCP连接和执行命令等方式来检查容器的健康状态。
通过在容器的配置文件中定义这些检查方式和参数，Kubernetes可以根据实际情况自动检测和更新容器的健康状态，并根据结果进行相应的调度操作。

使用Docker技术进行容器健康检查指南
使用Docker技术进行容器健康检查指南随着云计算和容器化技术的快速发展，Docker已成为最受欢迎的容器化解决方案之一。
然而，为了确保应用程序在容器中的可靠性和稳定性，进行容器健康检查变得至关重要。
本文将介绍如何使用Docker技术进行容器健康检查，以确保您的应用程序始终保持健康。
一、理解容器健康状态在开始进行容器健康检查之前，我们首先要理解容器健康状态的概念。
Docker 容器具有健康状态，用于指示容器是否正常运行。
健康状态有三种：健康（healthy）、正在进行健康检查（starting）和不健康（unhealthy）。
当容器处于健康状态时，表示应用程序正常运行。
当容器正在进行健康检查时，表示容器正在启动过程中。
当容器不健康时，则可能出现了故障或应用程序崩溃。
二、实施容器健康检查1. 使用健康检查命令Docker提供了健康检查命令，可以使用这些命令执行容器健康检查。
通过在Dockerfile中添加健康检查命令，可以在创建容器时自动执行检查。
例如，可以通过以下命令检查一个Web服务器容器是否能够正常响应HTTP请求：`HEALTHCHECK CMD curl --fail http://localhost:80 || exit 1`该命令使用curl命令检查localhost的80端口是否可以成功访问，如果无法正常访问，则健康检查失败。
2. 设置健康检查间隔除了执行健康检查命令外，还可以设置健康检查的间隔时间。
默认情况下，Docker每30秒执行一次健康检查。
可以通过在Dockerfile中添加`HEALTHCHECK`指令来自定义检查间隔时间。
例如，可以使用以下指令设置每10秒执行一次健康检查：`HEALTHCHECK --interval=10s`3. 设置健康检查重试次数为了增加容器健康检查的可靠性，可以设置健康检查的重试次数。
默认情况下，Docker重试健康检查3次，如果连续3次都失败，则将容器标记为不健康状态。

在.NETCore中实现健康检查
在.NETCore中实现健康检查在.NET Core 中实现健康检查.NET Core中提供了开箱即⽤的运⾏状况检查，⾸先，我将在.NET Core API应⽤程序中执⾏运⾏状况检查，接下来，我们将使⽤DbContext集成SQL Server或数据库的运⾏状况检查，最后是如何实现⾃定义服务的运⾏状况检查。
在 Core中实现健康检查要实现运⾏状况检查，您需要在项⽬中安装Microsoft.AspNetCore.Diagnostics.HealthChecks。
接下来，在ConfigureServices⽅法中添加运⾏状况检查中间件。
public void ConfigureServices(IServiceCollection services){services.AddHealthChecks();services.AddControllers();}然后修改Configure⽅法，使⽤中间件:public void Configure(IApplicationBuilder app, IWebHostEnvironment env){eEndpoints(endpoints =>{endpoints.MapControllers();endpoints.MapHealthChecks("/health");});}现在，准备⼯作完成，运⾏程序然后访问 /health, 您将看到下边结果：HealthCheckService.NET Core提供了⼀个HealthCheckService类，我们可以把健康检查的放到我们的控制器中，就像这样：public class HealthController : ControllerBase{private readonly ILogger<HealthController> _logger;private readonly HealthCheckService _healthCheckService;public HealthController(ILogger<HealthController> logger,HealthCheckService healthCheckService){_healthCheckService = healthCheckService;_logger = logger;}[HttpGet]public async Task<IActionResult> Get(){var report = await _healthCheckService.CheckHealthAsync();return report.Status == HealthStatus.Healthy ? Ok(report) :StatusCode((int)HttpStatusCode.ServiceUnavailable, report);}}现在，如果您尝试访问/health，您将看到相同的结果。
NetCheck使用说明书
NetCheck使用说明一、原理Netcheck是CTI平台开发的网络检测工具,用于检测两台机器之间网络是否正常。
平台各服务器间使用ICDCOMM通迅，ICDCOMM底层用TCP/IP通迅，因此检查出TCP/IP通迅不畅后即可定位为网络问题而不是平台程序问题。
netcheck分服务端和客户端，相互间通过TCP/IP通迅。
客户端向服务端的监听端口发起连接，客户端连到服务端后匀速向服务端发消息，具体过程是发完一个消息后延时50ms再发另一消息，即一秒钟最多能发20条消息，每条消息有唯一的序列号标识，标识从0开始每次加1。
服务端收到客户端的消息后判断1秒内收到消息的条数，当条数在20条左右时认为正常，具体是多少条为正常在配置文件中配置。
因不同网络传输时延有所不同，机器处理性能也有所不同，因此收到合法条数的下限有区别，如有的网络每秒只能收到16条消息包，但有的网络每秒可收到17条消息包。
NetCheck服务端最多支持八个客户端连接，消息从客户端发往服务端，服务端不会发消息到客户端。
一个目录下的netcheck只能启一个netcheck程序，需要运行多个netcheck程序时需新建目录将netcheck.exe、netcheck.log文件拷入，并修改配置文件后再运行。
目的是为了每个netcheck都能正确的记录下日志。
二、配置配置文件与可执行程序在同一目录，文件名为netcheck.ini。
配置文件中有各配置项说明，在此强调三点：a．服务器端口配置时不能配置为icdcomm使用的端口，否则可能会引起icdcomm异常。
b．消息内容长度字段必须保证服务端与客户端一致，否则netcheck检查消息内容时会出错。
一般用默认值34就可以了，不必修改。
需要修改时最好保持DataLen值加上14(消息头长度)的和能被16整除，这样有利于分析抓包结果。
c．客户端需要配置客户端IP地址，因为机器可能有多个IP，当不指定IP时系统默认用第一个IP，而此IP并不是用户想检查的IP。

在Docker技术中使用容器的健康检查和自动恢复策略
在Docker技术中使用容器的健康检查和自动恢复策略使用Docker技术的健康检查和自动恢复策略Docker是一种开源的容器化平台，它提供了轻量级、可移植和可扩展的容器化解决方案。
在使用Docker进行应用程序部署时，容器的健康检查和自动恢复策略起到非常重要的作用。
本文将介绍在Docker技术中使用容器的健康检查和自动恢复策略的方法和步骤。
一、容器健康检查容器健康检查用于监控容器的状态，包括容器启动、运行和停止等。
通过定期对容器进行健康检查，我们可以及时发现容器是否正常运行，并采取相应的措施进行修复或者替换，以保证应用程序的稳定性和可靠性。
1. 容器健康状态检查方式Docker提供了多种容器健康检查的方式，包括：- CMD检查：使用CMD命令执行应用程序的健康检查，并根据检查结果返回0或者非0的退出码。
例如，我们可以在Dockerfile中添加如下命令：`CMD [ "python3", "/app/healthcheck.py" ]`，其中healthcheck.py是一个自定义的健康检查脚本，根据实际应用程序的需求编写。
- HTTP检查：容器监听一个特定的HTTP端口，并根据HTTP响应码来判断容器的健康状态。
例如，我们可以在Dockerfile中添加如下命令：`HEALTHCHECK --interval=5s --timeout=3s CMD curl -f http://localhost:8080/ || exit 1`，其中的curl命令用于发送HTTP请求，并根据返回结果判断容器的健康状态。
- 自定义脚本检查：通过自定义脚本来检查容器的健康状态。
例如，我们可以在Dockerfile中添加如下命令：`HEALTHCHECK --interval=5s --timeout=3s CMD /app/healthcheck.sh`，其中healthcheck.sh是一个自定义的健康检查脚本。
如何进行Docker容器的健康检查和自动修复
如何进行Docker容器的健康检查和自动修复Docker容器的健康检查和自动修复是保障容器稳定性和可靠性的重要环节。
通过定期检查和自动修复，可以有效避免因容器故障而造成的系统不稳定和服务中断。
本文将介绍如何进行Docker容器的健康检查和自动修复。
一、Docker容器的健康检查Docker容器的健康检查是指通过监控容器的状态和指标，判断容器的运行情况是否正常。
这些指标可以是容器的CPU使用率、内存使用率、网络连接状态等。
根据实际情况，可以定制化定义健康检查的指标和阀值。
1. 使用Docker健康检查命令Docker提供了一系列的命令来检查容器的健康状态。
比如，可以使用"docker inspect"命令来查看容器的详细信息，包括容器的健康状态。
使用"docker stats"命令可以实时监控容器的各项指标。
通过这些命令可以快速了解容器的健康情况。
2. 自定义健康检查脚本除了使用Docker提供的命令，还可以自定义健康检查脚本来对容器进行健康检查。
通过编写脚本，可以根据实际情况对容器运行情况进行更加细致的监控和判断。
比如，可以编写一个脚本定时检查容器的CPU使用率，如果超过设定的阀值，则认为容器不健康。
二、Docker容器的自动修复当容器的健康检查结果不正常时，需要采取相应的措施来修复容器，以保证服务的连续性和稳定性。
下面介绍几种常见的自动修复方法。
1. 重启容器当容器的健康检查结果为不健康时，可以通过重启容器的方式来修复容器。
可以编写一个脚本，监控容器的健康状态，当发现容器不健康时，自动执行"docker restart"命令来重启容器。
重启容器后，容器的状态会重新回到健康状态。
2. 迁移容器除了重启容器，还可以采用容器迁移的方式进行修复。
当容器的健康检查结果不正常时，可以将容器迁移至另外一台宿主机上。
通过迁移容器，可以将故障节点上的容器迁移到健康节点上，从而保证服务的连续性。

上面0b.24为末分陪的状态；重新指定给netapp1机头使用，操作如下:
? 硬件状态检查
Filer>sysconfig –r 检查磁盘情况正常情况：发现所有磁盘，每个机头都有一个或多个spare disk。非正常情况：任何一个机头一个spare disk都没有，就是非正常情况。
Filer>sysconfig –v 检查所有硬件以上显示结果应该没有failed,error,warning 等字样.
8:netapp1> 服务和应用已还给netapp2了,
双机cluster 运行状态正常 能正常接管冗余服务
显示硬盘的分配owned情况: disk show –v
如:1) neapp1> disk show -v
