Website monitoring is the testing and verification process that end users can interact with web sites or web apps as expected. Website monitoring is often used by businesses to ensure the expected time, performance, and functionality of the website.
Website monitoring companies provide the ability for the organization to monitor the website, or server function consistently, and observe how it responds. Monitoring is often performed from multiple locations around the world to specific websites, or servers, to detect problems related to general Internet latency, network hop issues, and to prevent false positives caused by local or inter-connection problems. Monitoring companies generally report these tests in various reports, charts, and graphs. When errors are detected the monitoring service sends notifications via email, SMS, phone, SNMP trap, pagers that can include diagnostic information, such as network tracking routes, code retrieval from web page HTML files, web page screen shots, and even website videos fail. This diagnostic allows network administrators and webmasters to fix problems more quickly.
Monitoring collects extensive data about website performance, such as load time, server response time, page element performance that is frequently analyzed and used to optimize the performance of the website further.

Monitoring is very important to ensure that the website is available to users, downtime is minimized, and performance can be optimized. Users who rely on websites, or apps, for work or fun will frustrate or even stop using apps if they are not available reliably. Monitoring can include many things that need application functionality, such as network connectivity, Domain Name System records, database connectivity, bandwidth, and computer resources such as free RAM, CPU load, disk space, events, etc. Commonly measured metrics are response time and availability (or uptime), but consistency and reliability metrics are gaining popularity. Measuring website availability and reliability under varying amounts of traffic is often referred to as load testing.
Website monitoring also helps to benchmark your website against competitors' performance to help determine how well a site is performing. Website speed is also used as a metric for search engine rankings.
Website monitoring can be used to make web hosting providers responsible for their service level agreements. Most web hosts offer 99.9% operational time warranty and, when operating time is less than that, individuals can be restored for excessive downtime. Note that not all hosts will return an individual for excessive downtime so one has to be familiar with the terms of service of their hosts.
Most paid website monitoring services will also offer security features such as virus and malware scans that are increasingly important as websites become more complex and integral in business.

Internal vs. external
Website monitoring can be done from inside and outside corporate firewalls. Traditional network management solutions focus on in firewall monitoring , while external performance monitoring will test and monitor performance issues across the entire Internet backbone and in some cases to end-users. Third-party website performance monitoring solutions can monitor internal (behind firewalls), external (customer-facing), or cloud-based Web applications.
Inside firewall monitoring is performed by specialized hardware that can help you determine whether your application's sluggish performance is due to: app design, internal infrastructure, internal applications or public Internet connections.
External performance monitoring is also known as end user monitoring or end-to-end performance monitoring.
Real-time user monitoring measures the performance and availability experienced by actual users, diagnoses individual incidents, and tracks the impact of changes.
Website availability size
Protocol type
Website monitoring services may check other internet protocols besides HTTP and HTTPS pages such as FTP, SMTP, POP3, ActiveSync, IMAP, DNS, SSH, Telnet, SSL, TCP, PING, UDP, SOAP, Domain Name Expansion, SSL Certificate and various ports. Monitoring frequency occurs at intervals once every 4 hours to every 15 seconds. Typically, most website monitoring services test the server, or app, from once per hour to once per minute.
Advanced monitoring services capture browser interactions with websites using a macro recorder, or browser add-ons like Selenium or iMacros. This service tests the website by running a web browser through regular website transactions (such as shopping carts) or custom scenarios, to examine user experience issues, performance issues, and availability errors. Browser-driven monitoring services detect not only network and server issues, but also web page object issues (such as slow loading of Javascript, or third-party hosted page elements).
Implementation of time performance monitoring for Apache HTTP Server is mod_arm4 module.
Type of monitoring
Website monitoring users (usually network administrators, web masters, web operating personnel) can monitor a single page of the website, but can also monitor complete business processes (often referred to as multi-step transactions).
Monitoring servers from around the world
Website monitoring services typically have servers around the world - South America, Africa, North America, Europe, Africa, Asia, Australia and other locations. By having multiple servers in different geographic locations, monitoring services can determine whether a web server is available across the continent through the Internet. Some vendors claim that the more locations, the better the images are in the availability of your website while others say that three stations that are distributed globally are enough and more stations do not provide more information.
Type
There are two main types of website monitoring
- Synthetic monitoring is also known as active monitoring, and
- Passive monitoring is also known as real monitoring.
Notification options: alert
Because the information carried by website monitoring services in many cases is urgent and perhaps very important, various notification methods, commonly known as "warning" are used: email, IM, public and mobile phones, SMS, fax, pager, Skype, RSS Feeds, SNMP trap, URL notification, etc.
Website monitoring service
The website monitoring market is very competitive. There are 100 active service providers and over 60 have been documented out of business. Most providers offer free plans with low frequency monitoring.
