QUESTION
I'm experimenting with Prometheus to monitor and visualize the performance of several Java services. Works great and with Grafana the visual overview is very impressive.
But I don't seem to find how you can configure Prometheus itself to prevent its web interface to be publicly available. Grafana does this out of the box...
If I want to run everything on a cloud server, it would be great if I could check the /graph and /targets URL for instance, to check if everything is working OK before creating dashboards in Grafana.
Anyone who can point me to the right documentation? I went through this page, but didn't find exactly what I was looking for: https://prometheus.io/docs/prometheus/latest/configuration/configuration/
For info, this is my docker compose:
...ANSWER
Answered 2021-Jun-07 at 23:57Prometheus doesn't implement it's own authentication|authorization.
Your best approach is to secure access to all host(s) running all software and, in this case, to the hosts running these Docker containers and all targets that you scrape etc.
All cloud providers provide ways by which you may limit access to the resources you create with their platforms. You'll want to become familiar with your preferred platforms' mechanisms and you should establish confidence, in part, by proving to yourself that you're able to restrict access to your services when you deploy then to these platforms.
Perhaps start with a simple test web site, secure it, then test that it is secure. Once you're confident in doing this, deploy your Prometheus services.

I have a deployment with scale=1 but when I run get pods, i have 2/2... When I scale the deployment to 0 and than to 1, I get back 2 pods again... how is this possible? as i can see below prometeus-server has 2:
...ANSWER
Answered 2021-Jun-03 at 19:39Two containers, one pod. You can see them both listed under Containers: in the describe output too. One is Prometheus itself, the other is a sidecar that trigger a reload when the config file changes because Prometheus doesn't do that itself.
QUESTION
We have a client apps running on ios and android phones. We are generating events that we currently send to intercom. We would like to have these events in prometheus.
Is there a quick solution to have them in prometheus, with examples online? If there is not a solution online, would it be a bad idea to add an endpoint clients call with the event and the server exposes it to prom scraper?
...ANSWER
Answered 2021-May-29 at 14:09In order to let prometheus pull data from your app you have to use a client library from prometheus. There is a list of these organized by the programming language that you ca use https://prometheus.io/docs/instrumenting/clientlibs/ .
But if you don't want or you cannot let your application expose the events using those libraries you can push the events to Pushgateway and let Prometheus pull data from it. "The Pushgateway is an intermediary service which allows you to push metrics from jobs which cannot be scraped. For details, see Pushing metrics." From https://prometheus.io/docs/practices/pushing/
You can configure it on your prometheus.yml config file
QUESTION
So, the case I have is I am deploying a product, I am using prometheus/grafana for metrics. Weird things may happen and I want to get the metrics for investigation. I want to instruct the customer support team on how to get them and hand them over for investigation, but I cannot make it work.
So, following these pages:
- https://prometheus.io/docs/prometheus/latest/querying/api/#snapshot
- https://groups.google.com/g/prometheus-users/c/0ZkYVj_8X8Q
- https://devopstales.github.io/home/backup-and-retore-prometheus/
I generated the snapshot on the server and it is saved in a directory named XXXXX-XXXX/XXXXX. I copied this file locally.
Out of commodity, I created a docker compose like this:
...ANSWER
Answered 2021-May-20 at 18:03Solved. My mistake - and it's true, the documentation is not 100% clear either.
So, I had the snapshot stored in a directory like {DATA}\{XXXX-XXXX}\{YYYY}. My mistake was I was copying the content of directory {XXXX-XXXX}\{YYYY}. I should have copied the content of directory {XXXX-XXXX}. Did that and it works.
Also it worth to note the fact that it may take a while to have those metrics visible.
QUESTION
Let me start with the fact that I like asynchronous code. I would never wrap async code in a sync wrapper in production, but it is still something that I want to learn how to do. I am talking about specifically in Node.JS, not the browser. There are many ways to access the result of an async function synchronously like using child_process.spawnSync or a worker and Atomics. The issue with these ways is this:
ANSWER
Answered 2021-May-18 at 22:01I found the npm package deasync. In it, there is a line of code: process._tickCallback(). I implemented it as a function. This will only resolve a promise that has been completely fulfilled. For example:

QUESTION
I'm new to development and I'm trying to build my first project with TDD. I got this function (handleAsync) from a tutorial supposed to catch errors in async route handlers. To truly understand how it works, I am trying to come up with some tests.
./utils/handle-async.js
...ANSWER
Answered 2021-May-13 at 22:46Recall that handleAsync doesn't execute the handler - it only creates the middleware. You're also expecting it to not throw, but rather to pass the error on via the next callback. That's the reason you're using a middleware like this - so you can have async route handlers and have any possible errors be passed automatically to next so that the errors get passed to your error handler.
You can test whether it actually catches a promise rejection from a wrapped route handler. Here's an example, which I haven't had the chance to test:

I have just registered some metrics in a NestJS application, through a typescript decorator. I use the prom-client package, but although I can log the metrics registered, the endpoint is not exposing those, and the Prometheus docker instance that I use to show all metrics, are not showing those neither.
how can I do to view registered metrics in /metrics endpoint and the Prometheus dashboard?

Install prom
You can use prom like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
