Multi-Cluster Prometheus: Scaling Metrics Across Kubernetes Clusters
Tags: prometheus, multicluster
Published: 2024-01-26 20:11:03

Building upon [Bartłomiej Płotka's](https://www.bwplotka.dev) insightful [blog](https://prometheus.io/blog/2021/11/16/agent/) on Prometheus and its passthrough agent mode, this post dives into implementing multi-cluster Prometheus support. Notably, the official inclusion of support in the widely-used kube-prometheus-stack came with the release in [July 2023](https://github.com/prometheus-community/helm-charts/pull/3520), making it easier to extend Prometheus monitoring across clusters.

## Helm Configuration: Connecting Global and Edge Clusters
To deploy a Prometheus agent in your Kubernetes cluster, use the kube-prometheus-stack chart with Helm installed and configured on your cluster.

### Global Cluster Configuration
Update and apply global cluster values to enable remote metrics reception:
```yaml
prometheus:
  prometheusSpec:
    enableRemoteWriteReceiver: true
    enableFeatures:
    - remote-write-receiver
```

### Edge Cluster(s) Configuration
Update and apply edge cluster values to enable remote metric writing:
- Specify the global cluster's `${hostname}` remote write endpoint.
- Include a scrape configuration to identify pods annotated with `prometheus.io/scrape`.
- Assign a unique `${name}` to distinguish metric results.

```yaml
prometheus:
  agentMode: true
  prometheusSpec:
    remoteWrite:
      - name: ${name}
        url: https://${hostname}/api/v1/write
     # Add additional remote write configurations if needed
    additionalScrapeConfigs:
      - job_name: 'kubernetes'
        kubernetes_sd_configs:
          - role: pod
        relabel_configs:
          - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
            action: keep
            regex: true
          - target_label: cluster
            replacement: ${name}
```

These resulting metrics are illustrated within the global Prometheus cluster, featuring an Apache web service managing ingress traffic in a cluster labeled as "edge."

![Prometheus Output](https://quack-public-bucket.s3.amazonaws.com/prometheus_edge.png)

## Troubleshooting
Prometheus exposes internal metrics for effective troubleshooting. For in-depth troubleshooting steps, refer to the detailed [Grafana Labs blog post](https://grafana.com/blog/2021/04/12/how-to-troubleshoot-remote-write-issues-in-prometheus/).

Key metrics to monitor:

- Queue Tracking: `prometheus_remote_storage_highest_timestamp_in_seconds` and `prometheus_remote_storage_queue_highest_sent_timestamp_seconds` will track the backlog/queue.

- Shard Considerations: `prometheus_remote_storage_shards_desired` should be less than `prometheus_remote_storage_shards_max`. If it is greater, you may want to consider updating `max_shards` - see [Prometheus Parameter Tuning](https://prometheus.io/docs/practices/remote_write/#parameters).
What is overengineering
Tags: discuss, beginners, programming, hasanelsherbiny
Published: 2024-01-26 20:10:15

how many times you have started a side project to address a simple idea, but after few days a lot of things have come to your mind and you wanted to make it perfect, and whenever you think about a small enhancement or a feature you think about why don't we make it more better or increase the scale to include more things.
this is called overengineering, it's not only limited to side projects or ideas that comes to your mind but also it can extend to your daily tasks.

![overengineering](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j63nyockyr6356bk2ywh.jpg)

 for example if you want to create a simple login service which has a clear requirements, you start asking why don't we add MFA for example , or external login provider or even integrate with SSO server.

sometimes this thoughts are good as it widen your vision and can reveal some hidden or forgotten requirements but it's also can be very overwhelming, as this adds complexity to your task, cost, bugs, scalability issues or Unnecessary features.

## How to avoid overengineering ?

1. KISS Principle (Keep It Simple)
   don't try to add more things to your solution before making sure that it's really requirements.
2. Clear Requirements
   to be able to apply KISS principle properly you need to have Clear Requirements
3. Refactoring
   regularly review and refactor code to eliminate unnecessary complexity as refactoring helps maintain a clean and maintainable codebase without compromising functionality.
4. Avoid Premature Optimization
   avoid optimizing code or introducing advanced features prematurely. Optimize only when performance issues are identified through profiling or when necessary for scalability.
5. Pragmatic Design Patterns
   choose patterns that align with the project's needs, as design patterns can be beneficial, applying them excessively or inappropriately can lead to overengineering.

MD Office Interior Design Guide
Tags: interiordesigner
Published: 2024-01-26 18:54:42

The way how an office space looks and feels can impact the first impression of an employee or a client. So people can judge the work environment of an office just by the way it looks.

An MD’s office is a private and confidential space that at times serves many formal and informal guests. The **[office cabin design](https://www.daftardecor.com/
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/y60poo7h1ejiwaj9wibo.jpg))** of the Managing Director’s space has to be matched by the position as he is one of the top positions in the company. 

This office space has to deal with different kinds of guests, clients, and meetings so it is important to design the MD cabin interiors that would serve every purpose.
Interior designing tips

Now let us explore some basic guidelines that can help you design an MD office cabin that reflects your brand’s identity and optimizes productivity. 

You can also implement these ideas while designing your own office.
Branding and Aesthetics
The office cabin should be visually appealing, incorporating the company’s logo, and colour schemes. It should align with the brand as it will bring elegance and add to the aesthetics of the whole design of the office.
Positive company image
An MD’s office should be crafted and designed in such a way that it should reflect a company’s positive image to the clients. A well-designed office not only reflects professionalism but also communicates organizational values.
Install proper lighting
Lighting plays an important role as poor lighting can directly impact health and productivity. So it is necessary to maintain the right balance of natural light and artificial light in an MD office cabin. Adequate brightness levels are crucial for a productive and comfortable work environment.
Use high-quality material
Using high-quality material in the MD’s office is required because it will last for a longer duration and the need to repair will not arise soon.

It will give a premium look to the whole office if good quality material is installed in the office.
A cabin should be Spacious
An MD’s office must have enough space for meetings, document storage, a desk area, a waiting area, etc. The cabin must have enough space for the convenience of the official so that he can properly focus on performing his duties.
Choosing colour Scheme
Colour selection for the MD’s cabin should be done carefully as the office environment is quite formal. So, the usage of sober and light colours is highly recommended. And If too many vibrant colours are used it may distract the calmness and focus of people inside the cabin.
Summary

An MD’s office cabin should be comfortable, and luxurious, and it should be designed to fit their social status. 

Office interiors have the power to influence people’s moods and emotions. Thus designing an office is the most important decision a company can make when creating an identity and healthy workplace. The best interior designers in Gurgaon follow these guidelines while designing an MD cabin that reflects productivity and positivity.
Creating and Migrating a Schema in Laravel
Tags: programming, laravel, database, softwaredevelopment
Published: 2024-01-26 18:54:26



In this tutorial, we'll walk through the process of creating a schema with four fields (id, name, address, timestamp) and migrating it to be used in the database using Laravel's migration feature.

## Step 1: Creating a Migration

1. Open your command line interface.
2. Run the following command to create a new migration file with a descriptive name:
   bash
   php artisan make:migration createuserstable
   3. This command will generate a new migration file in the `database/migrations` directory.

## Step 2: Defining the Schema

1. Open the newly created migration file (e.g., `2024_01_26_093217_create_users_table.php`).
2. Inside the `up` method, define the schema for the `users` table using the `Schema` facade. Add the required fields and their data types:
   
   `use Illuminate\Database\Migrations\Migration;
   use Illuminate\Database\Schema\Blueprint;
   use Illuminate\Support\Facades\Schema;

   public function up()
   {
       Schema::create('users', function (Blueprint $table) {
           $table->id();
           $table->string('name');
           $table->text('address')->nullable();
           $table->timestamp('createdat')->useCurrent();
           $table->timestamp('updatedat')->default(DB::raw('CURRENTTIMESTAMP ON UPDATE CURRENTTIMESTAMP'));
       });
   }`
   
## Step 3: Running the Migration

1. To run the migration and apply the schema to the database, execute the following command in the command line:
   `bash
   php artisan migrate`
   2. This will create the `users` table in the database with the defined fields.

Congrats! You've successfully created a schema for a `users` table with four fields and migrated it using Laravel. It's now ready to be utilized in your database operations!

Microservice architecture provides a lot of benefits from fault isolation to scalability improvements. This allows the team to increase their velocity from ideation to deployments. 

Adaption of such architecture comes challenges like service discovery, authentication and authorization, and centralized logging. How are we going to address these?

## Here comes Istio 🚀

Istio is an _**open source service mesh**_ that layers transparently onto existing distributed applications. Istio’s powerful features provide a uniform and more efficient way to secure, connect, and monitor services. 

https://istio.io/latest/about/service-mesh/

## With Istio We can do

* **Traffic routing** allow A/B testing by splitting traffic based on different kinds of scenarios

* **Fault injection** Test application reliability by introducing errors. faults are injected in the form of:

  * _Delay_ - Mocks timing failures like network latency, overloaded upstreams

  * _Abort_ - Mocks crash failure scenarios upstream service failure and http error codes

* **Circuit Breaker** Sets request calls to your application like number of concurrent connections and how many times your application could be called. Once certain parameters has been reach, circuit breaker will activate and prevent specific clients from making further connections.

* **Timeouts** Allows your application to wait for replies protecting your application for long hanging requests

* **Retries** Gives your application the ability to retry request before returning an error. Focuses on reducing transient network failures that will help improve resiliency.

* **Mirroring** Ability to shadow the same amount of traffic to a mirrored service. Minimize the risk of deployment issues in your production environment.

### Overall

Istio allows you to implement _application resiliency_, _reliability_ and _safe deployment implementations_. It simplifies implementation of your network use cases without any changes to the application code. Want to learn more? Deep dive by visiting the istio website.

Setting Up Razor Support in Neovim for Enhanced C# Development
Tags: dotnet, csharp, neovim, blazor
Published: 2024-01-26 18:30:48

When working with C# in web development scenarios, especially when dealing with ASP.NET Core projects, having support for Razor can significantly improve your productivity. Fortunately, Neovim’s flexibility allows you to set up a development environment tailored to your needs. Here’s how you can integrate Razor support into your Neovim setup.

## Step 1: Install the vim-vsnip Plugin

First things first, a snippet plugin can be a real time-saver. `vim-vsnip` is a popular choice among Neovim users. To install it using `vim-plug`, add this line to your `init.vim`:

```vim
Plug 'hrsh7th/vim-vsnip'
```
https://github.com/hrsh7th/vim-vsnip

Afterwards, run `:PlugInstall` in Neovim to get the plugin installed.

## Step 2: Add vim-csharp to Neovim

The `vim-csharp` plugin adds nice enhancements for C# development. To include it in your toolset, simply place this line in your `init.vim` under the plugins section:

```vim
Plug 'OrangeT/vim-csharp'
```
https://github.com/OrangeT/vim-csharp

Save your changes and run `:PlugInstall` to finalize the addition.

## Step 3: Locate Your Snippet Directory

`vim-vsnip` will need to know where to find your snippets. To discover the default snippet directory, issue the following command in Neovim:

```vim
:echo(vsnip_snippets_dir)
```

Note down the directory path that appears—it’s typically found at `~/.vsnip`.

## Step 4: Copy Snippet Files to the Right Place

Now, you need to copy the snippet files from `vim-csharp` to your `vim-vsnip` snippet directory. If you installed the plugin via `vim-plug`, they should be located in `~/.local/share/nvim/plugged/vim-csharp/snippets`. Use this command in your terminal to move them over:

```sh
cp ~/.local/share/nvim/plugged/vim-csharp/snippets/*.snippets ~/.vsnip
```

Adjust the paths as necessary if your setup differs.

## Step 5: Configure Neovim for Razor Files

For Neovim to recognize `.cshtml` and `.razor` files and associate them with the proper filetype, include these lines in your `init.vim`:

```vim
autocmd BufNewFile,BufRead *.cshtml set filetype=html.cshtml.razor
autocmd BufNewFile,BufRead *.razor set filetype=html.cshtml.razor
```

With these settings, Neovim will apply the correct syntax highlighting and other filetype-specific behaviors for Razor files.

You can also install Mason and Nvim-cmp if you would like those features.

By following through with these steps, you've now equipped Neovim with a sharper edge for C# and Razor development, paving the way for a more streamlined coding experience. Whether it’s crafting intricate Razor pages or diving deep into C# logic, your Neovim setup is now up to the task.
DSA Series Part 1: Arrays
Tags: dsa, beginners, learning, codenewbie
Published: 2024-01-26 18:15:52

Hey everyone, I’m Sarah. This post will begin my journey of learning in public. To recap where I’m at: I’ve completed CS50 and I’m doing my undergrad in Computer Science. I made a simple web app and wanted to make more complicated stuff, but I couldn’t because you need algorithms to solve the complicated stuff. 

I’ll be following Abdul Bari’s course on Udemy and Algorithms Part I by Princeton on Coursera. The reason why I picked these courses is because I want to go over the concepts thoroughly. I also enjoy using low level programming languages. 

Now onto arrays themselves. Arrays are data structures that store a lot of the same type of thing. So an array will store a lot of integers, it will store a lot of booleans but it will not store booleans and integers. When you make an array of a certain size you can’t change the size in a whim. You have to make a new array of the size you want and then copy the elements of the old array into it. 

Python complicates things here: arrays are not built into python. In Python the alternative is using an external library or a list. However, you can increase the size of a list easily and you can, unlike what I’ve said before, store different types of things together. So it isn’t acting exactly like an array. I’ve searched online and they act more like a dynamic array or a doubly linked list.

The main reason you cant usually change the size of an array is because the elements are stored right next to each other. After allocating that space we cannot hope that memory is free around the stored array.


![A diagram showing an array as a sequence of boxes, there's a question mark next to the array to imply that we don't know whats there](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/u26epdmqpznp3osirlp7.png)

Now why would you want to store a lot of the same type of thing? Because you can organize a bunch of information and you can make simple simulations. I once used a 2D array to stimulate flowing water. It wasn’t quite the same as beautifully animated water but it got the job done. That’s about all I can think of for arrays. See you guys on the next one.
