health-monitoring

问题 I'm looking for a walkthrough on how to create and use a custom provider for ASP.Net Healthmonitoring. So far I've only worked with the e-mail provider that generates e-mails on errors. Basically I want to do the same, but with more flexibility: I want to use the HealthMonitoring features (I don't want to use the Application_OnError event in the global.asax) in a way that allows me have access to an event, that gets thrown like "OnNewHealthMonitoringEntry" with all the information provided in

问题 Is it possible to periodically check the health of an application? I have two scenarios in mind: During deployment I want service fabric to rollback if the health check fails Application is successfully running but still want to periodically run a health check in case a dependency is unavailable Currently I expose a healthcheck operation and I have traffic manager polling it. I have the following to flag it as unhealthy.. var context = FabricRuntime.GetActivationContext(); context

问题 I'm working on a new OS-X Daemon process (run from launchd) and would like to get popup window every time it crashes with all relevant information (pid, path to crash file, etc...). This will sure help my debugging effort in this early stage of the development. Basically, i want to have the same behavior as a UI application. For example : I've made some research and found out about the CrashReporter, but i don't know how to register my app to this service. But it seem like there's no way to

问题 I have an application running in Kubernetes. To take the advantage of rolling updates with no downtime, I have to implement the proper Health Checks, so the cluster can know when the application/container is ready to handle requests. I'm trying to use the new ASP.NET Code 2.2 Healthchecks feature. I should return a Microsoft.Extensions.Diagnostics.HealthChecks.HealthCheckResult struct with the status of the application. This struct has 3 static methods that I can use to return this status:

问题 I'm looking at a fresh asp.net site in 3.5 that has absolutely no error handling or logging. What are some good options for logging and handling errors? I've used Log4Net on the 1.1 framework but hear there are potentially better options in 3.5. 回答1: One option is ELMAH. I asked a question about it here: ASP.NET Error Handling. Since then, I have implemented a slightly modified version of it and the logging plus e-mail is great and easy to integrate via the web.config file. 回答2: We use two

问题 I have been able to configure Hyperic HQ to identify servicemix 4, however, It could only see the "ServiceMix 4.x Garbage Collector" service. I would like to be able to monitor activemq Queues, Endpoints, and Camel Applications (if possible) Has anyone been able to do this? 回答1: I ran into the same issue at a client recently. We didn't find any support for doing this with HypericHQ, so we built our own basic web app using JSP, Ajax/jQuery and JMX to interface with AMQ/Camel. Another option is

问题 We have a simple Spring Boot application with Jersey. Spring Boot provides default monitoring end points http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#production-ready-monitoring Example: @Component public class JerseyConfig extends ResourceConfig { public JerseyConfig() { // registering resources from rest package packages("com.xyx.abc.rest"); } } The REST end points that are provided by Spring Boot are not available in the context of a Spring Boot Jersey

问题 I know this questions been asked, but hasn't really been answered. I've tried things from threads like this: Heart Rate With Apple's Healthkit I tried converting this from Objective-C to Swift but didn't work. My question is, what's the best way to read heart rate data from health kit. I want to be able to read every heart rate measurement from the time it started taking them, and I want to be able to see the time/day stamps of said measurements. I asked for permission here: import Foundation

问题 I've been working on adding healthchecks to my dropwizard service. The problem is dropwizard returns plain text responses when I run my healthchecks. And I can only add an optional string messages to this output. For example: * Available Disk Space: OK Disk usage is not critically high (my message string) * Available Memory: OK * CPU Usage: OK * deadlocks: OK Is there a way to return these messages in JSON format so that I can parse the output easily? Thanks a million! 回答1: You can pass

问题 I just did a HKSourceQuery and got some results. When I do a println of the results, I got this: <HKSource:0x156c1520 "Health" (com.apple.Health)>//description of the object How do I use this to make a predicate using the HKQuery.predicateForObjectsFromSource(/* source goes here */) 回答1: Here is the sample code in Obj-c, NSSortDescriptor *timeSortDesriptor = [[NSSortDescriptor alloc] initWithKey:HKSampleSortIdentifierEndDate ascending:NO]; HKQuantityType *quantityType = [HKQuantityType
