Great to see you again! This month, we've re-launched a Start with Dynatrace subforum, a place to go when starting your learning journey with Dynatrace. In this challenge, we'd like to stay with the theme and learn about your other knowledge-expanding resources 📚
In the old days, it would have to be a giant bookshelf or a library. In the modern world, you can find everything you need on your computer!
Tell us in the comments below, how you are learning and expanding your knowledge. What are your must-read books? What blogs or YouTube channels are worth recommending? Feel free to mention some valuable webinars, workshops or conferences!
Every participant of this month's challenge gets bonus 100 points, a great "Active Learner" badge, and unique opportunity to find out some tips on learning from other like-minded professionals. Maybe you'll be inspired and fill your physical or virtual shelf with something new! 💡
For learning I mostly prefer reading. I don't have anything specific, my go-to resource is just google.
There are so many sites, blogs and forums where you can find useful information.
Aside from that I like podcasts to stay up to date on topics and get new ideas.
Besides PurePerformance of course 😉 I would recommend checking out jupiter broadcasting for all things linux.
In my case it looks like this:
When it comes to APM/Dynatrace knowledge my main source is (sorry customers and partners!) our internal Slack, Stack Overflow and Wiki resources.
Whenever we need to create a new integration with a technology we didn’t have before I always go to Google first to try to find what others did before, or if the vendor has some documentation on the APIs or whatever it might be.
I can only learn if I do two things:
Like everyone else, I read books/tutorials, watch videos, webinars, etc. Main source is google, but the Company I work have an internal learning system and partnership with platforms such Udemy.
Then, I need to practice. I do create labs/sand boxes to deploy, configure and break things. Yep, you learn a ton when things are broken. There's when stackoverflow enters. 🤣
And when I think I started to know that thing, I try to teach that to someone else.
I have hours and hours of trainings provided to my team here in the Company. Dynatrace is mostly of these trainings.In fact, that's how I learned Dynatrace, teaching my team on how to use it.
And this works for anything you need to learn. IT or not.
Today I am volunteer teacher, teaching English, Spanish and German to people of my little community here in Brazil (Livramento de Nossa Senhora, Bahia), I have around 40 students. I am almost fluent in English, and know a bit of German, but barely can understand Spanish, and still, I am teaching the little I know to others. Every week, when we have class, I need to learn the words I will teach, so that's a great way of learning.
When it comes to learning normally i would use Dynatrace document and blogs which is one of best reference i have seen ever also sometimes checking the existing defects/bugs which have been raised and try to go through where most of the solutions would have already discussed . Given that fact Siebel/CRM is what i dont see any much use case with Dynatrace which we are trying to work on so on daily basis its a good learning .
Well, I have shifted mentally in the last weeks, and today I had another seismic shift.
In January, a client of ours told me that he was monitoring some very important specific infrastructure metric. I can tell you it has been well discussed here in the Community... Their monitoring involved a quite sophisticated math formula.
When I got the formula, I could read it, but not really understand it. My first try to understanding it, was searching for it in Google. I didn't get far... I then asked for help with some of my close contacts, but the mystery remained. No one had a good idea of what that formula meant!
Several days passed, till I had another idea: how about asking ChatGPT? It went like this (I still have screenshots):
Me: What does this formula mean: xxxxxxxxx
ChatGPT: The formula you provided is used to calculate the number ...
ChatGPT had managed to reply to my doubts almost instantaneously! It even managed the typo in the second question... Now, I had my doubts, but quickly googling for what ChatGPT had provided me, I understood it was the correct formula.
Now, looking at the formula and it's meaning, made me wonder that this formula might not be appropriate for this situation. So I asked ChatGPT if I should use this formula for this metric/situation? And ChatGPT replied: NO! You should not use this in this situation because of this and that...
Today, I got another taste of this. I cannot reveal much more for now, but I'm shifting all my queries to ChatGPT...
Don't believe everything ChatGPT tells you! I tried with one of the most recent unanswered questions here in the Community: https://community.dynatrace.com/t5/Cloud-platforms/Can-Dynatrace-collects-Aurora-Postgresql-explain-...
The reply from ChatGPT is visible below. I would say that it is not right... Which leaves of course a lot of questions...
Definitely, he didn't deserve to be on our watch list as for now 😉
For me it always start with google, when thing get too complicate, the next stop is asking my team leader @gilgi if he got any clue on how to proceed and the last resort is asking the guys from the external-rfo-help slack channel.
Keep forgetting about ChatGPT option, thanks to @AntonioSousa I hope I will remember to give it a try next time 🤗
For learning I love to use two sites:
Also I love to dive through Github projects, I follow lots of Podcast (mainly in spanish), and lots of YouTube videos:
There are several resources I use. The most frequent ones are of course the Dynatrace blog and the Performance clinics. did you know Dynatrace has its own youtube channel (https://www.youtube.com/@dynatrace) so that even you've missed a webinar it is uploaded there as well as to the university?
In addition I'm also using on my mobile an app called feedly that @kelvin_klein has introduced to me to follow up on the blogs publications. 3-4 blogs a week is something that is hard to follow.
Regardless of that, obviously Dr. google and the documentation is used, but I also go to github.com and am searching for code samples there amongst all of the Dynatrace related subjects.
I admit that I am reading less now (at least professional books) so online is my most valuable resource.
For me, I'm more of a visual/hands-on learner. There is a plethora of resources to expand your Dynatrace Knowledge from the Pure Performance sessions to the Dynatrace Community. Also I would say that the HoT sessions at Perform are invaluable and I would recommend them 100% time and time again.
Google is a great resource as well but, googler beware as you might not always find the answer to your question. When I get presented with a complex question that needs a solution, I like to take time to think about it. You don't always need to have an answer right away. For example tagging entities with their onboarded date for entities automatically onboarded into Dynatrace. Once I've come up with a potential solution I then apply it as a small Proof of Concept within a test environment to see if its viable. If so, it gets expanded and promoted to the other core environments, then I follow up with educational information around it. You'll notice my materials include Screen shots with steps along with a textual journey. That way I cover the users who are visual and reading learners, but also for users who are hands on learners, they can follow along with the steps and images provided.
As partner my primary source of knowledge is our customers. IT is moving so fast and it is impossible to know everything. But as Performance engineer I have to analyze as Doctor House and work with experts 👨⚕️
So I switch between different technical contexts every day and share what I have learned with my team and other customers. Virtuous circle!
Obviously I am using Google, LinkedIn, Twitter, Medium, APMDigest (https://www.apmdigest.com/), Gartner Report.
I also assisted at https://perfnow.nl/ in 2018. Great conference about Web Perf.
This year I was at Perform for the first time and it was incredibly inspiring.
For Dynatrace and APM knowledge like Mike mentioned, our internal Slack, Stack Overflow and the Community of course!!! Not to forget the Dynatrace Performance Clinic and Webinars. Other resources like Udemy, The Linux Foundation, Microsoft Learn...etc, it depends on the technology stack I am interested in.
Hi All members,
If talking about Dynatrace knowledge: I have 3 data sources: Community, Online Documentation, and Dynatrace Youtube Channel.
If talking about knowledge in global: first starting page is google after some forum: gitHub, ... and also some Youtube Channels.
