PRODUCT OVERVIEW

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 for 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

icon voip

End-to-end visibility

Jitter. 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). 

Icon alarm

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.

Icon sensor

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.

Icon coffee cup

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.

What IP SLA monitoring looks like in PRTG

Diagnose network issues by continuously tracking IP SLA operations on your Cisco devices. Show UDP jitter, latency, packet loss, and other key network performance metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot poor VoIP call quality and other connectivity issues.

The Cisco IP SLA sensor monitors Voice over IP (VoIP) network parameters using IP service level agreements (SLA) from Cisco. It can show the following:

  • Average jitter
  • Average, minimum, and maximum latency and RTT (round-trip time)
  • The ICPIF
  • The MOS
  • Number of lost, out-of-sequence, and late packets

QoS (Quality of Service) One Way

The QoS (Quality of Service) One Way sensor monitors parameters regarding the quality of a network connection between two probes. It can show the following:

  • Average, minimum, and maximum jitter
  • Average, minimum, and maximum packet delay variation
  • Corrupted, duplicated, lost, and out-of-sequence packets
  • Time to the last packet

SIP Options Ping

The SIP Options Ping sensor monitors the connectivity to a Session Initiation Protocol (SIP) server using SIP options "ping". The sensor sends auth and options requests to the SIP server. It can show the following:

  • Response code
  • Response time
SIP Options Ping

SNMP Cisco CBQoS

The SNMP Cisco CBQoS sensor monitors network parameters using Cisco's Class Based Quality of Service (CBQoS). It can show the following:

  • Current and maximum queue depth
  • Number of drop packets (without buffer)
  • Drop size
  • Pre-policy and post-policy size
  • Number of pre-policy packets

IP SLA Monitoring: 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.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
