PRTG IP SLA monitoring: What you’ll find on this page
PRTG makes IP service level monitoring easy
Custom alerts and data visualizations make it easy to monitor, identify, and prevent latency, jitter, packet loss, and VoIP call quality and connectivity issues.
Don't take their word for it…better measure and track IP SLA data
Service level agreements are the recipes of enterprise communications.
Just as recipes list the ingredients, proportions, and instructions you have to follow to create a mouth-watering dish, SLAs lay down the benchmarks your ISP, VoIP vendor, and other communication services providers must meet for their service to be up to an acceptable standard.
Except, if you don't check, you won't know whether your service providers are keeping up their side of the bargain (unless there's a noticeable degradation in service).
Paessler PRTG's preconfigured Cisco IP SLA sensor pulls key data from your Cisco routers in real time, and alerts you if performance goes below preset thresholds. That means smoother, more productive business calls, a more stable connection, and, most importantly, more bang for your buck.
Stress-free VoIP calls every time:
4 reasons why to choose PRTG as your IP SLA monitoring tool
End-to-end visibility
Jitter. Latency. Packet loss. Quality of Service. Bandwidth usage. PRTG brings together your most important VoIP and connectivity metrics in one place, so you can make sure everything's working as it should at a glance (and at any point during the day).
Real-time alerts
Network monitoring on autopilot. Once you've set your preferred warning and error limits, PRTG tracks them 24/7 and alerts you when your devices are at risk of going over or under. Which means you can swoop in and fix issues promptly, or call your ISP or VoIP provider to let them know.
Wide compatibility
No Cisco IP SLA-enabled network devices? No problem. You can still monitor VoIP, QoS parameters, your internet connection, and more. With more than 250 preconfigured sensor types, there's almost no limit to which hardware devices and network metrics you can track.
Peace of mind
With PRTG working tirelessly in the background, you'll have one… well, actually, several less things to worry about, for example troubleshooting in time. Make short work of your to-do list (and leave the office at a reasonable hour), safe in the knowledge everything's being monitored in your absence.
Start monitoring IP SLAs with PRTG and see how it can make your network more reliable and your job easier.

Easily find the source of the problem with our PRTG IP SLA monitoring solution
Real-time alerts and custom notifications make it easy to solve issues such as latency, jitter, packet loss, and VoIP call quality and connectivity issues.
PRTG is compatible with all major vendors, products, and systems
How it works: PRTG's IP SLA-monitoring capabilities explained
PRTG's preconfigured Cisco IP SLA sensor queries data from any IP SLA-compatible device using SNMP. It can continuously track the following parameters:
- ICPIF (Calculated Planning Impairment Factor), which measures how much VoIP voice quality has been impacted
- MOS, or mean opinion score: another measure of VoIP video and audio quality where five is the best and one is the worst
- Packet loss packet delay, and packet reordering
- Average VoIP jitter
- Average latency
- DNS and TCP round trip time
- Transaction RTT
PRTG also has dedicated sensors that work with non-IP-SLA-enabled and non-Cisco devices:
- The QoS (Quality of Service) One Way sensor, which tracks the quality of a network connection between two probes
- The QoS (Quality of Service) Round Trip, which tracks the quality of a network connection between a probe and a target device at a connection's endpoint
- The SIP Options Ping sensor, which measures a SIP server's connectivity
- The SNMP Cisco CBQoS sensor, for monitoring network parameters using Cisco's Class Based Quality of Service feature

Monitor IP SLA: FAQ
What is IP SLA monitoring?
IP SLA is a feature on Cisco devices such as Cisco IOS that enables you to track latency, jitter, packet loss, VoIP quality and other audio, video, and connectivity performance metrics in real time. Tracking these metrics makes it easier to spot (and fix) issues and optimize your resources. Just as important, it helps you make sure your ISP, VoIP vendor, and other communication services providers are meeting the minimum standards in their service level agreements.
How do I set up IP SLA monitoring in PRTG?
Setting up IP SLA monitoring in PRTG takes only a few minutes. Enter your IP SLA-compatible Cisco device's IP address and SNMP access data in PRTG, then add a Cisco IP SLA sensor and pick the parameters you want to monitor. Your device's current values should appear on your monitoring dashboard as soon as you're up and running.
My devices aren't IP SLA-compatible. Can I monitor the quality of VoIP calls another way?
Yes. PRTG also has several other sensors that can continuously keep an eye on key VoIP metrics like jitter, latency, response time, packet loss, and packet delay. These include Windows-compatible MOS monitoring sensors, and QoS monitoring sensors. You can also monitor quality of service not only via LAN, but also via VPN, Wi-Fi, and WAN by using PRTG remote probes.
What else can PRTG monitor?
Paessler PRTG is your all-in-one network monitoring tool. With it, you can keep an eye on the health and performance of your physical and virtual IT, OT, and IoT infrastructures – on premises or in the cloud. Monitor, for example, network devices (servers, switches, routers, firewalls), virtual environments, applications, services, websites, operating systems, network traffic/, environmental parameters, entire data centers, resource consumption, and much more.
What is a sensor in PRTG?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.
