kandi X-RAY | probe Summary

probe is a Go library typically used in Networking, HTTP applications. probe has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Probe is a command line tool that does one thing: interrogates a service to determine if it is alive/ready. Whether the probe result corresponds to aliveness or readiness depends on how the service handles connections and/or requests on the specified address.

            How do I set up healthprobe for a web application running on an Azure virtual machine?
            Asked 2021-Jun-16 at 00:05

            State of the application:

            • A single virtual machine which runs an apache server.
            • Application exposed via the virtual machine's public IP (not behind a loadbalancer)

            I have an healthprobe endpoint running that needs probed every few seconds to see if the app is up, and trigger an alert in case it is not.

            What are my options? I want to get the healthprobe up and running first, before I move to a virtual machine scale set and a load balancer.

            ...

            ANSWER

            Answered 2021-Jun-16 at 00:05

            Under Support+troubleshooting -> Resource health of your virtual machine portal panel, you can set up a health alert. You can then select under which conditions the alert should be triggered. In your case, Current resource status: Unavailable should work just fine. You can also implement a custom notification (E-Mail) under Actions or implement a logic that triggers an Azure Function or Logic App that performs an action when the VM is unavailable.

            To detect if your application in Apache server is working correctly you can use a monitoring solution that checks the Apache error logs.

            Kubernetes Probes - What is the order in which they examine the pod?
            Asked 2021-Jun-15 at 16:06

            looking to understand the order in which kubenetes examine the pods using the 3 type of probes- startup, readiness and live.

            How to understand or design these 3 probes correctly for normal applications? What is the chance of getting conflict or breaking the application if the startup probe has wrong entries

            ...

            ANSWER

            Answered 2021-Jun-15 at 16:06
            Startup probe

            This runs first. When it succeeds, the Readiness Probe and Liveness Probe are run continuously. If this fails, the container is killed.

            Use this for "slow staring apps", you can use the same command as Liveness if you want.

            The kubelet uses startup probes to know when a container application has started. If such a probe is configured, it disables liveness and readiness checks until it succeeds, making sure those probes don't interfere with the application startup. This can be used to adopt liveness checks on slow starting containers, avoiding them getting killed by the kubelet before they are up and running.

            From configuring probes

            Liveness probe

            This is used to kill the container, in case of a deadlock in the application.

            Readiness probe

            This is used to check that the container can receive traffic.

            QUESTION

            Is probing of a Pod retried after a readiness probe fails
            Asked 2021-Jun-14 at 12:32

            readinessProbe: Indicates whether the container is ready to respond to requests. If the readiness probe fails, the endpoints controller removes the Pod's IP address from the endpoints of all Services that match the Pod. The default state of readiness before the initial delay is Failure. If a Container does not provide a readiness probe, the default state is Success

            If the readiness probe fails (and the Pod's IP address is removed from end point), what happens next? Will the Pod's readiness probe conditions be checked again? Will it check again after initial delay? Is there any chance the Pod's IP address is added to the end point again (if the Pod self healed after readiness probe fails)? Will that Pod receive traffic again incase if it's healed?

            Asked 2021-Jun-13 at 20:51

            I have a deployment with two containers, let's say A and B.

            container A serves http requests, the important container in the deployment. has liveness and readiness probes properly set.

            Container B serves as a proxy to a certain third party service through an ssh tunnel, has a very specific usecase, but for whatever reason, the third party service can be unreachable which puts this container on a crash loop.

            You kind of can't. You could remove the readiness probe from B but any kind of crash is assumed to be bad. Probably your best bet is to change B so that it doesn't actually crash out to where the kubelet can see it. Like put a little while true; do theoriginalcommand; sleep 1; done bash loop on it or something so the kubelet isn't aware of it crashing. Or just make it not crash ...

            Fitnesse Slim runner cannot load .net 5 assembly: Error extracting manifest import from file (hr = 0x80131018)
            Asked 2021-Jun-09 at 15:38

            Running a test in Fitnesse gives:

            Could not complete testing: fitnesse.slim.SlimError: Error SLiM server died before Header Message could be read.

            I used ProcessExplorer to check and RunnerW.exe was running in 64bit mode. My code is compiled with "Any CPU", the only difference with another working project is that it is a .net 5 (core) project using FitSharp 2.8.2.1 NuGet package.

            Answered 2021-Jun-09 at 15:38

            Some things that finally got me up and running:

            1: Do not reference the executable (file ending with .exe) but refer to the .dll instead. No matter how it is compiled, trying to load the the .exe file as an assembly will always throw a System.BadImageFormatException.

            2: Fish the .Net Core versions of Runner.exe and RunnerW.exe (and their dependencies) out of the NuGet package and use those instead of the older SLIM .Net runners (if you are migrating). FusionLog does absolutely nothing with .Net Core, so if there is any logging going on then you know that the process is not running .Net Core.

            3: If you got the FitSharp projects from GitHub and are linking to the projects instead of using NuGet, then remove the post build actions to copy the files. Instead go to your test project Dependencies -> Projects -> fit open Properties (F4) and set the options Reference Output Assembly, Copy Local and Copy Local Sattelite Assemblies to Yes. Do the same for the FitSharp and Runner projects.

You can configure the ip_configurations property of the azure_rm_networkinterface to set the load_balancer_backend_address_pools, this property can associate the VM to the Load Balancer.

            As for why I'd like the gif to be read from memory is because I'm going to change this so gifs from urls will be wrapped in Bytesio instead of saving.

            For a single image your code is working fine.
            It looks like you are missing proc.wait() at the end and that's it.

            For multiple images, you may take a look at my post here.
            You may simplify the code, for working with images.

            I made few changes to your code, to make it more elegant (I think):

            • You don't need '-vsync', '0' argument.
            • I replaced '-' with 'pipe:' (I think it's more clear).
            • You don't need to set bufsize unless you know that the default is too small.
            • I removed stderr=SP.PIPE, because I wonted to see the FFmpeg log in the console.
            • I added proc.wait() after proc.communicate.

            The code sample starts by building synthetic GIF image file for testing.

            1. probeData shouldn't be an Array -- it should be an optional property
            2. That means when you decode, you shouldn't put it inside [ ]
