FAQs: Paessler PRTG

How is PRTG licensed?

PRTG Licensing Explained

PRTG is licensed by the number of sensors. In general, most devices might have 5-10 sensors. For network switches, you’ll probably want one sensor per switch port. Each sensor may have multiple channels, those additional channels on an individual sensor do not incrementally increase the sensor count. Examples of a sensor might include:

  • A ping test
  • Testing http/https URL(s)
  • A DNS query test
  • CPU load on a server
  • Traffic usage on a network switch port
  • There are over 200 predefined sensor types to choose from

What is PRTG network monitor?

PRTG Monitoring

PRTG monitors the general health, performance, status of various devices such as routers, firewalls, servers, storage systems, web servers, databases, VoIP systems, network flow data and more. There are over 200 predefined sensors and by using SNMP you can monitor even more. Better yet, PRTG is an all in solution, you get all of the predefined sensor types.

Does PRTG require a database server?

PRTG Database

PRTG does not require a separate database server (e.g. SQL Server, etc). This means that:

  • With the integrated database, performance is up to 100 times more than compared to SQL server
  • Less network load since everything occurs on the same platform (and sizing requirements are very reasonable)
  • One application to update, no coordination and additional maintenance hassles
  • Just one license for PRTG, no additional SQL licensing needed

What kind of support is available for Paessler PRTG?

PRTG Support

If you keep a maintenance contract in place (which you should), then you can get support directly from Paessler in Germany via Email and from 7 AM to 10 PM (UTC+1). Most questions are answered within 24 hours on business days. Contact Paessler support via support@paessler.com.

Altaware, Inc. is a highly certified reseller of PRTG, US based, with decades of engineering experience, extensive hands-on PRTG experience and breadth of IT skills. We're available via phone and Email during US west coast PST hours. We support numerous customers across the USA when hands-on skills and expertise are desired. Our services are billable in 15 minute increments for remote assistance.

What happens when your PRTG support contract ends?

PRTG Support Coverage Cancelation

If you choose to not renew your PRTG support after the first year, you still have a perpetual license and your existing product version you had while under contract will remain functional. Make sure to keep reliable backups, of course.

What you won't get then is:

  • Access to the continuous rolling updates for bugs and ongoing new features
  • Access to Paessler support tickets

Unlike a lot of competitors, Paessler continues to improve, enhance and maintain their excellent monitoring software. We strongly encourage keeping maintenance current for a vital and essential application like this. However, you don't have to keep support current to continue to utilize your license.

Please contact us to renew any lapsed support contracts or add additional PRTG sensor licenses.

Are there educational discounts for PRTG?

How much does PRTG maintenance cost?

PRTG Maintenance

When you initially purchase a new license for PRTG, you get one year of Paessler support and updates included. You can also purchase an additional one or two years on that initial purchase. After the initial period, the price will be 25% of the then current list price of the sensor count license.

How much do extra sites cost for PRTG?

PRTG Extra Sites

In terms of costs for extra sites, the answer is it depends:

  • If you monitor sites from a single instance of PRTG, that's basically extra sensors, so it depends on the number of sensors licenses that you purchased and have available.
  • If you want to monitor extra sites with remote probes, there is no additional cost for remote probes and the sensor licenses still apply. Remote probes can help address concerns due to firewalls, routers or WAN bandwidth.
  • If you want to create a clustered instance, there is no additional cost.
  • If you want to create a new stand-alone instance of PRTG for a site or collection of sites (e.g. west coast, east coast, DR site, different countries), then we recommend purchasing a higher level of license for additional core server installations.

Can PRTG be clustered?

PRTG Clustering

All of the self-hosted PRTG licenses include a core server license plus they allow for one failover node in a cluster. For multiple stand-alone core server installs, consider a special worldwide license from us.

How does PRTG support product updates?

PRTG Maintenance Updates and Feature Upgrades

By having a Paessler maintenance contract, you get access to continuous rollouts from Paessler. Unlike traditional software updates, that means:

  • Releasing software updates in substantially shorter cycles
  • Quicker access to important bug fixes
  • A product that evolves and improves more rapidly over time

How are additional sensor licenses added?

Adding more sensors to PRTG

PRTG is licensed by sensors and not devices or some other metric. If you want to add sensors to a device, add them. If you want to add devices, add them.

In the end, you are licensed by the number of sensors you want. You can remove, delete or pause sensors that no longer apply.

If you need to purchase more sensor licenses, it's based upon the current list price difference from the level you have and the level you want. No more anxious moments about oversizing (and over paying) or running out and then looking at an entire new purchase point.
