Follow our step by step Guide Lines :

Download Cacti link:
https://www.cacti.net/download_cacti.php

The latest stable version is 1.2.17, released 05/03/21
Cacti require MySQL, PHP, RRDTool, net-SNMP, and a web server that supports PHP such as Apache or IIS.

Before Installing CACTI on Windows Computer /Windows Server there are some Prerequisite:

Software Prerequisite:
Step1: Install XAMPP
Step2: Install Cacti Server
Step3: Configuring Database and Settings
Step4: Install RRD-Tool and net-SNMP
Step5: cacti post-installation settings

โŒš Timestamps
0:00 Cacti Introduction
0:52 Download & Install Xampp
1:47 Download & Extract Cacti Server
2:23 Download & Install Net-SNMP
2:31 Download & Install RRDtool
4:10 Setting PHP Timezone
9:21 Change Apache http/https Ports Number
11:02 Configure cacti DB
13:34 Cacti WEB Access
17:02 Fix Cacti Pre-Installation Checks Errors
23:39 Create Poller Script for cacti poller

Step1: Install XAMPP and settings
WARN:
1.It is highly recommended to set your system Date, Time, and ZONE
according to your country time, and zone.
2.XAMPP installation will be successful only if you have set the correct date, time, and zone
Under WINDOWs and PHP.
https://www.php.net/manual/en/timezones.asia.php

Once you have finished XAMPP installation you must change
Time & date under XAMPP Registry
I have already set my systems time and date I am going to change only the XAMPP time and date for PHP

3.Open Drive C: edit php.ini configuration file located in
C:xamppphp (file name (php) configuration setting)
Once you have changed the time& date must be restarted XAMPP

Probably your 3306 or whatever you use is being used by other applications. Maybe you don’t know that XAMPP usually has problems with apps like Skype. If you are running Skype try to close it and open XAMPP. You can also change default ports for HTTP and MySQL.
To Edit Apache ports open apache. conf and restart the server.
To Edit MySql ports open my.cnf and restart the service.

Step2: Import cacti folder under XAMPP register
File path: C:xampphtdoc

Step3: Create database and set DB name cacti
Import the cacti.sql file into MySQL database
NOTE:
Apache server did not open webpage if you have faced this error
You must change apache port

Step4:
Edit the cacti database settings located in
C:xampphtdocscactiinclude

Step5:
Open any web browser enter the IP address of your PC
http://127.0.0.1:8090/cacti
default username: admin
default password: admin

SQL command to set SQL time zone
MySQL -u root -p MySQL
GRANT SELECT ON mysql.time_zone_name TO cacti@localhost;
flush privileges;
exit

Note: if you did not fix SQL time and date errors you are still stuck then
download from here timezone list and copy-paste
C:xamppmysqldatamysql
https://dev.mysql.com/downloads/timezones.html
_________________________________________________

Scaling Interactive and Insightful Dashboards with Data Studio and BigQuery (Cloud Next '18)



Large datasets in BigQuery might make it cost prohibitive to scale dashboard solutions. Unless carefully designed, solutions can lead to queries piling up with repeated viewing and result in significant costs in BigQuery. Google Data Studio lets users build interactive shareable data visualizations using their BigQuery data. In this session, we will show the common failure points and how you can build scalable, interactive, insightful dashboards in Data Studio from BigQuery data.

With Felipe Hoffa and Minhaz Kazi, Developer Advocates.

PostgreSQL WAL and Commit Synchronization, Optimization Opportunities – Jobin Augustine



#PostgreSQL uses different types of #WAL records for recording activities happening on the database. A deeper understanding of what they are, how they are synchronized, what the optimization opportunities are, etc., can lead to a better-tuned system.

This talk also discusses the different sets of PostgreSQL parameters and their impact on WAL and optimization considerations for a high-performance database.

This talk covers:
What the WAL records are
Synchronization considerations
What is important from the host IO subsystem
Parameters for tuning
Different levels of tuning, Instance, Database, User, Session, and Transaction,
and how it impacts performance.
WAL Propagation to standby
Synchronous standby, important points to be considered
Remote write, flush, and replay stages.
This talk also includes small code snippets, demonstrations, and efficiency comparisons.

Building Resilient, Mission-Critical Applications with Azure Database for PostgreSQL | ๆ—ฅๆœฌใƒžใ‚คใ‚ฏใƒญใ‚ฝใƒ•ใƒˆ



Are you looking to deploy your mission-critical application to a managed Postgres database service that is secure, reliable, availableโ€”as well as performant and scalable? If yes, this session is for you. You will learn about the new Flexible Server option in Azure Database for PostgreSQL that gives you zone-redundant HA (my favorite topic) as well as more control of your database configuration, networking options, and maintenance window. You will also learn how Citusโ€”an open source extension to Postgres that transforms Postgres into a distributed databaseโ€”is changing whatโ€™s possible for data-intensive applications. Weโ€™ll walk through some interesting applications that are already scaling out with Hyperscale (Citus), a built-in deployment option in Azure Database for PostgreSQL. And weโ€™ll explore how Kubernetes has opened the door to running Postgres on Azure in hybrid scenarios, too.

Web Crawling vs. Web Scraping | Oxylabs



Web Crawling vs. Web Scraping – What’s the Difference?

A crawler, also called a spider, crawls through different websites and looks for two things:

1. For data (the user is searching for)
2. For more targets to crawl

For example, the process would look something like this:

The crawler goes to your predefined target e.g. www.example.com, and it crawls through and discovers various product pages. Once the crawler finds the products, this is where scraping comes in.

Web scraping happens when a scraper downloads product data (price, title, description, etc.)

So, if web crawling means going through and clicking on different targets, web scraping is the part where you take the found data and download it.
