Application performance management – standard & individual

What is application management?

Application management (also known as application performance monitoring or apm) ensures that all applications (standard software or web applications) perform as expected. This technique evaluates the performance of the applications and checks if everything is running smoothly.

Two different kinds of application management

When it comes to application performance monitoring, there are two different kinds to choose from:

  • Standard application management
  • Individual web application management

A recent trend in the area of monitoring solutions for individual web applications involves the use of cloud-based tools like New Relic and AppDynamics, which can monitor the performance of highly complex web applications at the source code level. Administrators and IT teams in SMEs, however, are less concerned by these tools; what they need are monitoring solutions which can monitor standard applications such as databases, mail servers, and firewalls.

PRTG is your all-in-one application manager

PRTG helps you to keep control over all your applications. You gain a concise overview on individual dashboards as well as detailed statistics about every application running in your network. If desired, you get a prompt alert whenever PRTG discovers a defined status (e.g. application doesn't respond or web server is offline). This allows you to react quickly before problems become severe.

3 great benefits of application performance management with PRTG 

Ensure business-critical applications run smoothly

Ensure business-critical applications run smoothly

Every company has business-critical applications. When these crash, the firm has a real problem and sales are in danger. PRTG starts with the web server, then checks the Exchange server, database applications, and all cloud or virtual environment applications. PRTG application monitoring software monitors all these processes centrally and automatically.


Monitor unusual network activity

Monitor unusual network activity

Everything seems to be alright – your applications are up and running with no sign of errors. Yet downtime can occur quickly if problems are not discovered immediately. PRTG not only comes with an application monitoring service, it also monitors bandwidth, traffic, data packets, and many other network elements and metrics.


Control the use of resources

Control the use of resources

How many resources are used by your applications? Are resources blocked, or are they used optimally? PRTG Application Monitoring Tool keeps track of all your applications, as well as their use of resources. The software signals alarms promptly, so you can act before capacity-related problems arise.


PRTG manages your server applications – thoroughly and reliably

 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

In most companies, the administrator is not only responsible for original network devices such as switches and routers, but also for the entire IT infrastructure - and thus for a whole series of standard applications, whose performance has a direct impact upon business-critical processes.

Increasingly, so-called unified monitoring solutions are being implemented to consolidate all the elements that are important to administrators into one single, comprehensive tool: from hardware to virtual systems, to traffic and line and device utilization, and even the availability and performance of standard applications.

PRTG Network Monitor is a prime example of a unified monitoring solution designed for companies of all sizes. Our monitoring software allows you to monitor each of the functions in your IT structure with just one tool, and comes with features for monitoring all your crucial standard applications.



SQL, Exchange & Co. in Ceck

PRTG monitors every important out-of-the-box SQL Server application:

  • Microsoft SQL Server 2005, 2008, 2012, 2014, 2016
  • Oracle SQL Server
  • MySQL
  • PostgreSQL

Furthermore, thanks to its ADO SQL v2 sensor, PRTG can embed into its application monitoring practically any database that is addressable via OLE DB (Object Linking and Embedding, Database) or ODBC (Open Database Connectivity).

Web Server Monitoring

Mail Server Monitoring

Email communication is still the backbone of nearly every company communication structure. In addition to the tools for monitoring a variety of email servers, PRTG provides standard tools for monitoring blacklists and round trip sensors for monitoring an email's entire send/receive cycle.

  • Exchange (Backup, Database, Mail Queue, Mailbox, Public Folder)
  • IMAP
  • POP3
  • SMTP

Web Server Monitoring

Web servers are the third group of standard applications found in most corporations. Because these servers are the basis for Internet and Intranet sites, they also require extremely high levels of availability and performance. Here too, PRTG covers the references of the field:

  • Microsoft Internet Information Services (IIS)
  • Apache

PRTG is able use its wide range of predefined sensors to automatically recognize IIS and Apache web servers.

Monitoring of virtualized environments and cloud applications with a single tool

Monitoring of virtualized environments

Virtualization is another technique that is currently playing a significant role in many corporations. If it is used properly, virtualization can save time, resources, and money. The prerequisite for this method, however, is an adequate level of availability and performance. PRTG comes with a comprehensive selection of sensors for all major virtualization platforms:

Sensors for the monitoring of virtualized environments

Monitoring of cloud-based applications

More and more, companies are turning to cloud storage services. Along with ensuring a fast and uninterrupted Internet connection, administrators must also monitor these cloud services directly. PRTG provides a full range of predefined sensors for all the leading cloud services:

PRTG also includes a sensor that monitors the availability and response time of a number of SaaS providers, including Bing, Facebook, Office 365, Salesforce, Twitter, and YouTube.
