How to Monitor Mpls with Thousendeyes: How to Monitor Mpls
Man, I remember the first time I tried to get a grip on our MPLS network performance. It felt like trying to herd cats in a hurricane. We were bleeding money on circuits, and the IT team was drowning in tickets that always circled back to ‘it’s slow.’
Everyone told me, ‘Just use the vendor’s tools!’ So I did. For about six months, I wrestled with clunky dashboards that showed me everything *except* what I needed to know about the actual user experience. It was a disaster, and frankly, a colossal waste of time and resources.
That’s when I started looking beyond the obvious, digging into what actually tells you if your network is working for the people using it. This whole mess is precisely why understanding how to monitor MPLS with ThousandEyes became my obsession.
It’s not just about blinking lights and packet counts; it’s about the real, tangible impact on your business.
The ‘vendor Portal’ Illusion
Seriously, don’t fall for the trap of thinking your MPLS provider’s portal gives you the full picture. It’s like asking the fox to guard the henhouse. They’ll show you their network is fine, their SLAs are met, but they rarely give you insight into how that translates to your actual application performance across different sites. I spent hours staring at graphs that told me nothing useful, feeling utterly helpless as users complained about missing deadlines because the VPN was dragging like a dead weight.
The dashboard looked pretty, I’ll give them that. Lots of green lights, happy little icons. But the actual user experience? That was a whole other story, a chaotic mess of dropped connections and applications that took ten minutes to load a single page.
Why Thousandeyes Actually Works
So, what’s the big difference? ThousandEyes essentially puts agents, or ‘tests,’ *on the path* from your users to your applications, wherever they are. It simulates user traffic. Think of it like having a relentless, meticulous quality control inspector who lives inside your network and at your branch offices, constantly checking if everything is running smoothly, not just for the pipes, but for the actual data flowing through them.
This is huge. It means you’re not just guessing. You’re seeing latency, packet loss, and availability from the perspective of a user in, say, Des Moines trying to access a server in London. It pulls back the curtain on those opaque MPLS circuits and cloud hops. This level of visibility is what separates ‘reacting to problems’ from ‘proactively preventing them’.

My initial setup took about four days, mostly tweaking test configurations to accurately reflect our most critical applications. After that, the insights started flowing. We identified a routing issue between two major hubs that was adding a solid 80ms of latency – something the carrier’s tools hadn’t even hinted at.
Setting Up Your Mpls Monitoring
Getting started with how to monitor MPLS with ThousandEyes involves a few key steps. First, you need to define what you’re monitoring. Is it your voice traffic? Your CRM application? Your cloud-based file sharing?
Second, you deploy agents. These can be virtual machines, Docker containers, or even hardware appliances. They sit at strategic locations: your data centers, your branch offices, and even in cloud environments like AWS or Azure. You’ll want a decent spread. For our organization, I ended up deploying 17 agents across our primary locations and key cloud VPCs.
Third, you configure ‘tests.’ These are the specific metrics and paths ThousandEyes will measure. For MPLS, you’ll likely want to set up:
- Network Tests: These measure hop-by-hop performance, showing you exactly where latency or packet loss is occurring within your MPLS network and beyond. You can see the path your traffic takes, which is invaluable when troubleshooting.
- Application Tests: These simulate user interactions with your applications. They measure page load times, transaction times, and overall availability. This is where you see the real impact.
- Voice/Video Tests: If real-time communication is critical, specialized tests can measure jitter, packet loss, and MOS (Mean Opinion Score) to ensure quality.
The sheer detail in the path visualization is almost overwhelming at first. You see every router, every transit provider, every cloud hop. It looks like a complex spiderweb, but once you learn to read it, it’s like having X-ray vision into your network’s backbone. It’s not just a line on a map; it’s a living, breathing entity.
What the ‘experts’ Get Wrong
Here’s a contrarian take for you: Many so-called ‘network experts’ still focus too much on the network layer alone. They’ll tell you to watch SNMP, BGP, and router CPU. While those are *part* of the puzzle, they’re often like checking the engine temperature while the driver is screaming because the GPS has them lost in a cornfield.
I disagree. The common advice to ‘just monitor the infrastructure’ is incomplete for modern networks, especially those involving MPLS and cloud. My opinion is that user experience monitoring, which ThousandEyes excels at, should be the primary lens. If your MPLS circuits are technically ‘up’ but your ERP system takes 20 minutes to load an invoice because of a bottleneck on an intermediate hop you don’t even own, then for all intents and purposes, your network is failing. It’s like having a brand-new, perfectly tuned sports car that can only drive at 5 mph because of a traffic jam on the single road leading out of town.

Comparing Network Monitoring Philosophies
Let’s get this straight. Traditional network monitoring tools often feel like looking at a weather map. You see the pressure systems, the cloud formations – the high-level stuff. You know a storm is coming, maybe. But you don’t know if it’s going to rain on *your* specific house.
ThousandEyes, on the other hand, is like having a weather station installed directly in your backyard. It tells you the exact temperature, humidity, wind speed, and precipitation *at your location*. It’s granular. It’s specific. It’s about the impact on *you*.
| Monitoring Tool Type | What It Shows You | My Verdict |
|---|---|---|
| Traditional SNMP/Netflow | Device health, bandwidth utilization, basic connectivity status. | Necessary baseline, but often misses the root cause of user complaints. Like looking at a car’s dashboard lights. |
| MPLS Provider Portal | Their network’s performance metrics, SLA compliance from their perspective. | Useful for carrier accountability, but completely lacks end-to-end user perspective. Pure marketing material. |
| ThousandEyes (Endpoint & Network Agents) | Actual application performance, path visualization, user experience from branch to cloud. | The gold standard for truly understanding network health from the user’s viewpoint. This is what you need for proactive problem-solving. |
Real-World Scenarios and Gotchas
One time, we had a recurring issue where our VoIP calls were breaking up intermittently. The MPLS carrier swore up and down their network was clean. We ran ThousandEyes tests, and immediately saw packet loss spiking on a specific transit link between our data center and one of their major aggregation points. The carrier *couldn’t* see it because they weren’t looking at that granular, hop-by-hop path from our perspective.
Another scenario: a company migrating a critical application to Microsoft Azure. They thought their MPLS back to the internet edge was the bottleneck. ThousandEyes revealed the issue wasn’t the MPLS at all, but rather misconfigured routing within Azure itself, specifically a Network Security Group rule that was silently dropping traffic under load. The sight of that specific Azure hop turning red with an error message was a revelation.
The sensory detail here is the sound of frustration. When users are complaining, the office buzzes with it. It’s the clicking of keyboards that are too slow, the sighs of exasperation, the hushed, angry phone calls. ThousandEyes helps you replace that sound with the quiet hum of a network that just *works*.
A common mistake I see is not configuring tests for every critical application. You might monitor your main ERP, but what about your remote desktop services, your cloud-based CRM, or your internal collaboration tools? You need to build out a comprehensive suite of tests that reflect your actual business operations. I initially focused on just three apps and missed a significant slowdown in our HR portal, which caused a minor panic during payroll processing. That taught me a valuable lesson: be thorough.
It also means you can precisely pinpoint who to call when something goes wrong. Is it your internal network team? The MPLS provider? The cloud provider? ThousandEyes gives you the data to know, saving you endless hours of finger-pointing. (See Also: How To Monitor My Sleep With Apple Watch )
What Are the Key Components of Thousandeyes?
ThousandEyes primarily uses Cloud Agents, Enterprise Agents (which can be deployed on-premises or in cloud VPCs), and Endpoint Agents. Cloud Agents are hosted by ThousandEyes in data centers worldwide, allowing you to test performance to cloud services and between global locations. Enterprise Agents provide visibility into your internal network and specific on-premises applications. Endpoint Agents are installed on user devices to give you the ultimate user-experience view, including browser performance and local network conditions.
How Does Thousandeyes Help with Mpls Troubleshooting?
ThousandEyes provides hop-by-hop path visualization across your MPLS network and the internet. This allows you to see latency, packet loss, and performance degradation at each network hop, identifying issues whether they lie within your MPLS provider’s network, transit links, or your own internal infrastructure. It replaces the ‘black box’ perception of MPLS with detailed, actionable data.
Can Thousandeyes Monitor Cloud Application Performance?
Absolutely. ThousandEyes excels at monitoring cloud application performance by testing from their Cloud Agents, your own Enterprise Agents, and even Endpoint Agents. It can measure availability, performance, and user experience from various vantage points to cloud services like AWS, Azure, Google Cloud, and SaaS applications, giving you end-to-end visibility.
Is Thousandeyes Difficult to Set Up for Mpls?
The initial setup requires planning to identify critical applications and deployment locations for agents. However, the platform is designed to be user-friendly. Configuring network and application tests is straightforward once you understand your network topology and application dependencies. Many organizations find the insights gained far outweigh the initial configuration effort, and vendor support is generally good for getting started.
Conclusion
Honestly, trying to manage an MPLS network without a tool like ThousandEyes in today’s distributed world feels like flying blindfolded. You’re making decisions based on incomplete information, and that’s a recipe for disaster and wasted money.
The data it provides isn’t just numbers; it’s the story of your network’s health from the user’s perspective. You get to see the real impact of latency and packet loss, not just theoretical metrics. This is how you finally get a handle on how to monitor MPLS with ThousandEyes effectively.
My advice? If you’re feeling the pain of network slowness and the frustration of not knowing *why*, start looking at path visualization and synthetic transaction monitoring. It’s the only way to truly understand what’s happening beyond the edge of your own network.
