Prometheus is an open-source system monitoring and alerting toolkit originally built at SoundCloud. Many companies and organizations have adopted Prometheus and have a very active developer and user community in the project. It is now a standalone open-source project and is maintained independently of any company.
Features of Prometheus:
A multi-dimensional data model with time series data identified by metric name and key/value pairs.
PromQL, a flexible query language to leverage this dimensionality.
No reliance on distributed storage; single server nodes are autonomous.
Time series collection happens via a pull model over HTTP.
What is Grafana?
Grafana is an open-source solution for running data analytics, understanding large amounts of data and monitoring our apps with the help of cool customizable dashboards.
What are the benefits of Grafana?
Customizable dashboards are feature-rich and can be configured to display data from a wide range of databases using visualization tools such as heatmaps, histograms, and charts.
The platform is flexible and easy to use.
Native support of a broad range of databases.
Grafana Features:
Dashboard templating – This is a Grafana feature that is really useful. It allows users to create a dashboard setup to suit their every need.
Provisioning – It can be simple enough to set up a single dashboard with a few clicks, dragging and dropping, but some users need even more ingenuity this way.
Annotations – This Grafana feature lets you mark graphs, which is especially helpful when you need to correlate data in case something misbehaves.
Custom plugins – You can extend the functionality of Grafana with plugins that provide additional tools, visualizations, and more.
Teams and permissions – Where an organization has an instance of Grafana and multiple teams, they usually prefer to have the option of implementing some dashboard isolation.

Hey folks, here we are with the topic of Python programming and its importance. Here we will discuss about python and its importance. Python is associate understood, object-oriented, high-level artificial language with dynamic linguistics. It has constitutional information structures, combined with dynamic typewriting and dynamic binding, creating it terribly engaging for fast application development, scripting, or as a glue language to attach existing elements along.
What is Python?
Python is integrated understood, object-oriented, high-level artificial language with dynamic linguistics. Its high-level inbuilt information structures, combined with dynamic writing and dynamic binding, create it terribly engaging for speedy Application Development, likewise as to be used as a scripting or glue language to attach existing elements along. Python’s easy, simple to be told syntax emphasizes readability and so reduces the value of program maintenance. Python supports modules and packages, which inspires program modularity and code apply. The Python interpreter and also the in depth normal library square measure out there in supply or binary type for gratis for all major platforms, and may be freely distributed.
Often, programmers fall loving with Python attributable to the redoubled productivity it provides. Since there’s no compilation step, the edit-test-debug cycle is implausibly quick. Debugging Python programs is easy a bug or unhealthy input can ne’er cause a segmentation fault. Instead, once the interpreter discovers miscalculation, it raises Associate in attention exception. Once the program does not catch the exception, the interpreter prints a stack trace. A supply level computer programme permits examination of native and world variables, analysis of impulsive expressions, setting breakpoints, stepping through the code a line at a time, and so on. The computer programme is written in Python itself, testifying to Python’s self-examining power. On the opposite hand, typically the fastest thanks to correct a program is to feature a couple of print statements to the source the quick edit-test-debug cycle makes this straightforward approach terribly effective.
How python works?
The Python, serves alternative programing language, which is fully arithmetic. This means that what you’ll do in Python, you can do the other programing language, and contrariwise. They’re all equally communicatory.
That said, Python will appear to be the language of selection in an exceedingly sort of domains (for example, machine learning) due to glorious library support, ability to quickly example, so forth. Personally, I notice Python partaking as a result of its therefore capable, however really easy to know.
It will have its “drawbacks” (depends on your perspective): dynamically written, taken, and so forth.
The Python converts everything in its interpreter to computer memory unit as C computer memory unit compiled code to mimic a compiled .dll file and writes it once the interpreter debugs it directly into a DLL file. And Pythons main.c file sets 2 loops into python main () to incorporate it and execute it in an exceedingly nested second loop. One loop is that the main loop and also the second is named in from the python. Which has the PyObject.dll with the pyobject second loop methodology.
What are the uses of Python?
Clearly, Python may be an in style and in-demand talent to be told. However what’s python programming used for? We’ve already shortly touched on a number of the areas it are often applied to, and we’ve dilated on these and a lot of Python examples below. Python are often used for:
AI and machine learning
Because Python is such a stable, flexible, and straightforward programing language, it’s good for numerous machine learning (ML) and AI (AI) comes.

Data analytics
Much like AI and machine learning, knowledge analytics is another chop-chop developing field that utilises Python programming. At a time once we’re making a lot of knowledge than ever before, there’s a requirement for people who will collect, manipulate and organise the knowledge.
Data mental image
Data mental image is another in style and developing space of interest. Again, it plays into several of the strengths of Python. Also as its flexibility and also the truth its ASCII text file, Python provides a spread of graphing libraries with all types of options.
Programming applications
You can program all types of applications exploitation Python. The general language are often accustomed scan and build file directories, produce GUIs and Apis, and more. Whether or not its block chain applications, audio and video apps, or machine learning applications, you’ll be able to build all with Python.
Web development
Python may be a nice selection for net development. This can be mostly because of the actual fact that there square measure several Python net development frameworks to decide on from, like Django, Pyramid, and Flask. These frameworks are accustomed produce sites and services like Spotify, Reddit and Mozilla.
What are the importance of python?
The Python is a general purpose and high level artificial language. You’ll use Python for developing desktop GUI applications, net sites and web applications. Also, Python, as a high level artificial language, permits you to target core practicality of the applying by taking care of common programming tasks. The straightforward syntax rules of the artificial language any makes it easier for you to stay the code base decipherable and application rectifiable. There also are variety of reasons why you must like Python to alternative programming languages.

rajeshkumar created the topic: Perforce Python Script Collection.
Implement a script that will do following:
1. Read config file. This file will contain following settings:
a. For mail delivery (SMTP)
b. For access to perforce server
2. Get from perforce a list of changes made since last script run time and get all updated files
3. Invoke script that will ‘build’ the changes – it will be located in the working folder of the
script(build.bat/build.sh). Script itself should come from perforce as well during step 2.
4. If running of build script is successful, add/update contents of folder named ‘bin’ in the perforce
repository (it is expected that build script will put there a product of its work)
5. In case of error of invocation, send out an email with the list of changes retrieved in p.2 and all outputs of
build script (both stdout/stderr), in which case contents of ‘bin’ folder should not be updated to perforce
Solution
Script details:
master.py – This file is the main file which should be excuted to get the all desired output as per the task
build.bat – This is a Build file which will be executing during compilation phase in master.py. config.ini: Following key should be modified as the environment specification
Sender
Receivers
Message
Host
p4port
p4user
p4client
p4passwd
Scenario to create fail Build:
Remove comment line from “REM mkdir raj” in build.bat
How to use?
Change the config.ini file appropriately and fire master.py script. If you find any issues, please follow the log error message accordingly.

pankaj2252369@gmail.com created the topic: Any possible Software/plugin for SCM workflow?
Hey Team, Thanks for lot of information on the site. wonderful work.
Any idea on SCM workflow software/framework ? which would help me to complete the SDLC lifecycle.
For E.g: When ever developers are done with their changes/check-ins, they would request CM team to build (via Email), And when CM builds and deploy , they will email to Testing Team, finally when its been tested they will let CM/RM team inform about the bugs, etc. finally product will be released.
All this was happening manually(via emails). If we have a workflow software, so that we can have everything in process oriented and SCM would be very easy.
Any Suggestion are welcome.
If know of any plug-ins , we can extend our programs to make it work to our systems.
Thanks in Advance!

Thanks for the response. But this i snot actually i am looking for.. I have idea on the mentioned tools. But wanted to create one separate tool for our internal purpose. So i am just checking, if there are any SCM related plugins /frame works in market, So that i do not spend more time on the things that are available.
Anyways.. Thank you so much!
rajeshkumar replied the topic: Re: Any possible Software/plugin for SCM workflow?
Hi John,
May be i am getting confused from you questions. Framework which can help you to develop your internal tools????
You mean you would like to develop your own tools, Then you might want to identify the technology first using which you want your development work get started. There are plenty of framework in Java| C++ | Perl | Pythin| Php | Ruby on rails etc
