Warning, avoid Datadog at all costs

Unless you are an enterprise with a lot of money to burn stay away from Datadog. They lure you with low prices on their pricing page and charge you a completely different sum at the end of the month.

They are very very shady and disgusting company to deal with.

Here is how we got scammed by Datadog.

​

1. We have one VPS that we wanted to monitor, nginx, mysql, php etc. the usual
2. We did the trial and setup everything and it all works great
3. Their pricing page states $15 per month (yearly) and $18 monthly for infrastructure monitoring, which sounds great
4. At the end of the month our card was charged over **$700** !!! Because of "usage" from ingestion of logs. **Nowhere** on this pricing page does it state that you need "log management" service for the infrastructure plan. Not even in the pricing details. I looked very closely for additonal charges and usage fees on their pricing page before signing up and there is none.

**We basically pay $700 per month to monitor 1 VPS server.**

This is INSANE.

Luckily I did not onboard our other servers or the charge would be 3-5 times higher.

The log management is divided up into its own section on the pricing page, indicating that it is a different service. Just like "APM", "Network" etc. is divided up into its own sections. Services which we did not use.

I had to cancel my credit card and have the bank send me a new one to avoid being fraudulently charged by this company.

I am filing a fraudulent chargeback with my bank.

It is a shame that a company with such a good service has to scam their customers instead of being upfront with the pricing.

Now that I am done with this shitty company, is there any similar service that do not scam their customers? Or do I have to setup my own Prometheus stack?

Essentially I just want to monitor the daemons on the server and alert me when things break.

DevOps Career Success Mini Series

Hey Everyone,

In these trying times I've talked to a lot of DevOps learners hoping to build a successful DevOps career after being let go or denied internships in other fields. Some of them are fresh grads and some already have experience programming or in software QA automation. I've built a mini series that will take you through DevOps from the beginning, starting with DevOps culture and moving onto the high level concepts like automation and CI/CD before getting into specific tools like Terraform and AWS.

The course is totally free and delivered via email once or twice a week with homework to keep you busy in between. It should be doable by someone with a job or someone already studying in university.

You can sign up here for the series if this sounds like something that would be helpful for you: [https://miniseries.opscentric.io/devops-career-success](https://miniseries.opscentric.io/devops-career-success)

Also feel free to PM me if you have questions, this course is the result of my mentoring sessions with aspiring DevOps Engineers over the last few years. So far most of them have gone on to get well paid jobs in the field or be promoted to higher salaries.

Tips for a software developer?

We have started researching Docker about over a week ago and have managed to grasp the basics and have now managed to dockerize our current project, but it's like a rough sketch, we're all novices and assuming this rough sketch has a big room for improvement.

We don't have a DevOps team, we're all essentially developers, we have a few seniors with a bit more experience with setting up and configuring servers, and it seems that we're going to be on our own for a while, and we have only ever been using bash scripts for deployments.

I'm a bit intimidated/worried basically because we're introducing new tools into our workflow, and we're currently discussing the next step which is deciding which CI/CD tool to use. The more senior members of the team are leaving in a week, and I'm not sure if I can fully commit to this. I feel like we need more time? Or if we're going to start looking into all this new stuff and experimenting, I feel like we need at least some sort of safety net that should we run into any trouble we struggle to fix, it won't keep us from shipping a product and any updates needed. Or maybe have a consultant or specialist with more experience, but it seems that our manager wants us to get the hang of this and manage it all on our own.

Thoughts?

Best practices for CI/CD with containers

what is the most efficient way of deploying containers throughout the SDLC? Let's start with local development. Engineers test code and submit PRs against a branch, call it "develop." Unit testing runs and at some point we need to push all these changes to a shared development environment for others to see and qa to test (we don't have a testing environment). Now, the idea behind containers is that you run the same containers across the environment.

If the develop branch evolves due to PR and merges throughout the day, the shared development environment will have a new docker image each time there's an update. how would we know which container to push to staging and then prod? do we need to introduce a second branch?

need some ideas and tips

How does your team link/manage Jira tickets and Git branches?

Hi team,

Hoping someone can weigh in on this common pain point. We use Jira for issue tracking like many teams and git as version control. A few main issues:

1. As developers are assigned tickets and work off of feature branches and merge to the develop branch, we've had issues making sure that the tickets correspond to branches and transition to the merge status when merged. We've managed this with a plugin where we have to prepend our branch names with the ticket number, but I was wondering if there is a better and more reliable way
2. We cutoff once a week and tickets are automatically assigned a fix version with a jenkins job. However, tickets are sometimes merged after the cutoff and have to be manually assigned a fix version and managed. This is inefficient and leads to situations where a dev has merged and then moves on; the feature is untested and released because QA is only looking at merged tickets in the latest version. Ideally I'd like to automatically assign the latest fix version upon a merge to the staged QA branch. Is there a more elegant way to manage this?
3. We haven't figured out a way to efficiently manage the "latest" fix version and its state. We just think what the latest is, increment in our heads, and bulk assign all the tickets to the new version when we cutoff. I'd love to reduce this down to one click, where we cutoff and the version is incremented automatically. But we'd need a way to keep track of the last fix version.

Collect inspec test results from multiple hosts

So far, I was able to integrate inspec with ansible to run the profiles across all of our 30+ hosts in our environment. The result being the json report is present in individual host. Is there any way we can get data from those reports and publish it to show compliace level per host?

I have read [https://www.reddit.com/r/devops/comments/7ycwaw/what\_tool\_can\_i\_use\_to\_aggregate\_serverspecinspec/](https://www.reddit.com/r/devops/comments/7ycwaw/what_tool_can_i_use_to_aggregate_serverspecinspec/) which doesnt give any answers

I tried geekdave/prometheus\_inspec\_exporter and it gives me a total tests run/skipped/failed but the results doesnt match the output json file.

Chef compliance server is decommisioned where we could push all these reports and get a summary view and Chef automate is a paid tool.

Are there any other option for collecting and showing these reports ?

HTTP request queueing mechanism question

We have a Kubernetes cluster with around 30 microservices running. In front of the cluster we have nginx acting as a front end web server/reverse proxy to Ingress nginx within the cluster. What is the best way set request rate limit based on the URL to each of the services? For example we need to queue 100 requests to a certain service after 30 concurrent requests, and drop all the requests if the queue of 100 is full. Also set a timeout for requests in the queue say for 30 seconds.


I know that nginx has built-in module to set rate limits but it is very limited and restrics only based on the requester IP address and not URL. Also it doesn't have queues.

Developers may implement this into the services themselves, but this approach may become complex to manage and fine tune after they are deployed.

Please share your experience on this.

DevOps contract roles: pros and cons?

Hello,

I lost my job back in February due to an acquisition related re-org. Perfect timing right? Locally lots of positions are drying up, but I'm seeing an uptick in contract roles coming in from recruiters. I was hoping the community might have some insight on the potential gains or pitfalls of accepting a contract gig like this, aside from the lock in that comes with a contract. Thanks!

A Prometheus fork for cloud scale anomaly detection across metrics & logs

Gavin from Zebrium here. We've just published/open-sourced a Prometheus fork with the following features:

1. Metrics are streamed in near real-time.
2. Uses very little network bandwidth (testing shows 500x reduction over raw).
3. It does not store metrics locally (no TSDB).
4. Every sample scraped locally will reach the remote server (i.e no dropping of metrics because of timestamp ordering issues).
5. Adds extra labels, that can be used to join these collected metrics with the logs. Please see our fluentd log collector which adds similar labels [here](https://github.com/zebrium/ze-kubernetes-collector)

Details in [this blog](https://www.zebrium.com/blog/a-prometheus-fork-for-efficient-cloud-scale-autonomous-monitoring) and [this Github](https://github.com/zebrium/prometheus) repository.

Java / Spring - 2020 Application Deployment?

Hi All, I've been dumped back into Java world after a 10+ year hiatus.

In terms of shipping applications, what is the go to in 2020 for shipping monolith applications?


In a previous life I would just spin up Jenkins, build and scp JAR files around. Yuck, but it got the job done. I don't have K8s handy, and I really couldn't be bothered spinning up a cluster for for a single application + database that doesn't need to scale.

Infrastructure will most likely be VMs in the public cloud (AWS, Azure or GCP). Something that could handle all three would be great.


Help / pointers greatly appreciated.

Beginners Luck!! (Looking for help)

Hey there,


Let me tell you about my background a bit. I am someone who has pretty good exposure in the development area and knows and comfortable with Java, C#, Python, etc. I have worked as a game development using unity3D.

Currently, I am a student of Network and Security field. I like networking as much as I loved development and I am constantly looking for something to merge them. From what I researched I think DevOps is the way to go further. However, for something as big as DevOps I am still a beginner and have basic exposure working with Python, Linux or Cloud tech. I wonder if there is something pretty basic that I need to know.


Looking for a list of courses for beginners. (Free courses preferred(As there are so many things going free during these quarantine time)/paid welcomed) Also, it would be a great help if someone can guide me further for my said path. How right is it and how can I get good at it.

P.S. Feel free to private message me if you want to discuss it.

Kibana dashboard question. I don't get it.

I am attempting to build a dashboard using Elasticsearch + Metricbeat where I have successfully sent data from metricbeat to the elasticsearch server.


What I think is simple is not, at least for me, and would like a quick understanding.

I am attempting to get a dash of Numbers reflecting the current CPU usage on each machine. This way at a glance I can tell if our CPU spikes after a push.

Do distributed file systems partition a file across nodes?

In HDFS, a file is partitioned into blocks which are distributed across several nodes.

I am wondering if that is also true in the following distributed file systems: NFS, Andrew File systems, Bayou, Coda?

is Ansible "exact_count" provisioning the same as Terraform provisioning ?

hi guys, I havent used both tools enough, but when i was looking at the [AWS provisioning feature](https://docs.ansible.com/ansible/latest/scenario_guides/guide_aws.html#provisioning) of Ansible...i find it exactly similar to Terraform's declarative feature.

It basically gets you to the desired state. isnt it pretty much the same as terraform then ?

Install Hashicorp Vault independently without Consul

Hi, my organisation is looking forward on installing Hashicorp Vault as our K/V manager to provide secrets to our K8s cluster and local development securely.

Most of the examples and Terraform files were bundled with Consul. Do I really need Consul? I don’t think Vault will not function without Consul.

All help will be appreciated.

And also maybe you can point me to some tutorials or Git repos. Thanks!
