Meraki Insight: Application Performance Monitoring

Application performance is the lifeblood of modern business. When your cloud-hosted CRM grinds to a halt during peak hours, when video conferences freeze mid-sentence, or when your point-of-sale system takes thirty seconds to process a transaction, the root cause is rarely obvious. Is it the application itself? The internet connection? The local network? The WAN link? Cisco Meraki Insight answers these questions by providing deep, actionable visibility into application performance across your entire network — from the client device to the cloud.

In this guide, we explore how Meraki Insight works, what it monitors, and how UK businesses can use it to proactively identify and resolve application issues before they impact productivity and revenue.

What Is Meraki Insight?

Meraki Insight is a cloud-based application monitoring and WAN performance analytics tool integrated directly into the Meraki dashboard. Unlike traditional network monitoring solutions that focus primarily on link utilisation and device health, Insight takes a user-centric approach, measuring the actual experience of end users as they interact with business-critical applications.

It achieves this by analysing traffic flows at the Meraki MX security appliance, correlating network telemetry with application performance data, and presenting the results through an intuitive web-based interface. There is no additional hardware to deploy and no agents to install on client devices — Insight works transparently with your existing Meraki MX deployment.

For UK businesses running distributed networks — retail chains, multi-site offices, hospitality groups, healthcare trusts — Insight provides a single pane of glass for understanding application performance across every location.

The Problem Insight Solves

Consider a typical scenario. A regional manager at your Edinburgh office reports that Salesforce has been "slow all week." Your IT team checks the Meraki dashboard and sees that the MX appliance is healthy, the uplink is not saturated, and the firewall rules are correct. They contact the ISP, who confirms no issues on their end. They open a ticket with Salesforce support, who reports all systems operational. Days pass. The problem persists. Nobody can pinpoint the cause.

This is the "finger-pointing gap" that plagues IT teams worldwide. Each party — the ISP, the application provider, the internal network team — sees only their slice of the picture. Meraki Insight bridges this gap by measuring the complete path from the user to the application, identifying exactly where latency, packet loss, or jitter is being introduced.

How Meraki Insight Works

Meraki Insight operates by passively monitoring traffic flows through the MX appliance and actively probing application endpoints to build a comprehensive performance picture. Here is how the key mechanisms work.

Application Recognition

Insight uses deep packet inspection and Meraki's extensive application signature database to identify traffic by application. It recognises over 250 applications out of the box, including Microsoft 365, Google Workspace, Salesforce, Zoom, Teams, SAP, and many more. You can also define custom applications based on IP address, hostname, or port number for internal or niche line-of-business tools.

WAN Health Scoring

Each WAN uplink on every MX appliance receives a health score calculated from latency, packet loss, jitter, and availability metrics. This score is updated continuously and displayed on a timeline, making it trivially easy to spot degradation. If your primary ISP in your London headquarters experienced a period of high latency between 14:00 and 16:00 on a Tuesday, it will be clearly visible in the Insight timeline — complete with precise measurements.

Application Health Scoring

Beyond WAN health, Insight assigns a health score to each monitored application based on the actual experience of users at that site. This score incorporates the WAN metrics but also factors in DNS resolution time, server response time, and the overall round-trip time to the application. A healthy score indicates that users are having a good experience; a degraded score triggers an alert and provides drill-down data to identify the cause.

Hop-by-Hop Analysis

When performance degrades, Insight performs hop-by-hop analysis to pinpoint exactly where in the path the issue lies. It distinguishes between problems occurring on the LAN (your internal network), the WAN (your ISP or SD-WAN overlay), and the application server itself. This eliminates guesswork and dramatically accelerates troubleshooting.

Setting Up Meraki Insight

One of Insight's greatest strengths is its simplicity of deployment. Because it is built directly into the Meraki cloud platform, there is no separate server to provision, no software to install, and no complex configuration to manage. Here is a step-by-step overview of the setup process.

First, ensure your Meraki MX appliances are running the latest stable firmware. Insight requires MX firmware version 15.x or later, which is standard on all current deployments. Next, navigate to the Insight section of the Meraki dashboard and enable monitoring for your desired networks. You can select which applications to monitor — we recommend starting with your five or six most business-critical applications and expanding from there.

Configure your application list by selecting from the pre-built library or defining custom applications. For each application, Insight will begin collecting baseline performance data immediately. Within 24 to 48 hours, you will have enough data to establish normal performance patterns, after which anomaly detection becomes highly accurate.

Key Features in Detail

WAN Uplink Comparison

For organisations with dual-WAN or SD-WAN configurations — increasingly common amongst UK businesses seeking resilience — Insight provides a side-by-side comparison of uplink performance. You can see at a glance which ISP is delivering better performance for each application, enabling data-driven decisions about traffic routing and failover policies.

This is particularly valuable for businesses using a combination of MPLS, broadband, and 4G/5G backup links. Insight shows exactly how each link performs for each application, helping you optimise your SD-WAN policies for cost and performance.

Historical Trending

Insight retains performance data for extended periods, allowing you to identify trends that develop over weeks or months. Perhaps your primary ISP's performance has been gradually degrading during business hours as more tenants in your building come online. Perhaps a specific application has become slower following a provider-side update. These slow-moving trends are invisible without historical data, and Insight makes them immediately apparent.

Custom Alerts and Thresholds

You can configure alerts to trigger when application or WAN health drops below a defined threshold. These alerts integrate with the Meraki webhook system, meaning you can push notifications to Slack, Microsoft Teams, PagerDuty, or any other platform your IT team uses. For UK businesses with lean IT teams — which describes the majority of SMEs — automated alerting ensures that issues are caught early, often before end users even notice.

Site-by-Site Comparison

If you operate multiple UK sites, Insight allows you to compare application performance across locations. This is extraordinarily useful for identifying site-specific issues. If Microsoft Teams works flawlessly in your Bristol and Leeds offices but struggles in your Norwich branch, Insight immediately highlights the discrepancy and provides the data needed to investigate.

Troubleshooting Workflows

Meraki Insight transforms troubleshooting from an art into a science. Below are the typical workflows we recommend to our UK clients.

Scenario 1: Slow Cloud Application

A user reports that their cloud-based accounting application is running slowly. In the Meraki dashboard, navigate to Insight and select the application. Check the application health score for the user's site. If the score is degraded, drill into the details to see whether the issue is on the LAN, WAN, or server side. If the WAN shows high latency, check the uplink health to determine whether the ISP is at fault. If the server response time is elevated, the issue lies with the application provider — and you now have data to prove it when raising a support ticket.

Scenario 2: Intermittent Video Call Quality

Video conferencing issues are notoriously difficult to troubleshoot because they are often intermittent. Insight's continuous monitoring captures performance data around the clock, so even if the issue occurs at 09:15 on a Monday morning during the all-hands meeting, the data is recorded. Check the WAN health timeline for spikes in jitter or packet loss that correlate with the reported issues. Jitter above 30 milliseconds or packet loss above 1% will noticeably degrade video quality.

Scenario 3: Comparing ISP Performance

You suspect that your secondary ISP is underperforming relative to your primary. Navigate to the WAN health section and compare both uplinks over the past 30 days. Insight provides average and peak latency, packet loss, and jitter for each link, enabling a data-driven conversation with your ISP or a decision to switch providers.

Insight and SD-WAN Integration

Meraki Insight becomes even more powerful when combined with Meraki SD-WAN. SD-WAN allows your MX appliances to dynamically route traffic across multiple WAN links based on real-time performance metrics. Insight provides the visibility layer that informs these routing decisions.

For example, if Insight detects that your primary broadband link is experiencing elevated latency for Microsoft 365 traffic, the SD-WAN policy can automatically shift that traffic to your secondary MPLS link or 5G backup. This happens transparently, without user intervention, and Insight records the event for your review.

In the UK, where businesses increasingly rely on a mix of full-fibre, FTTP, leased lines, and mobile broadband, this combination of Insight and SD-WAN delivers enterprise-grade application resilience at a fraction of the cost of traditional WAN architectures.

Licensing and Requirements

Meraki Insight requires an Insight licence, which is available as an add-on to your existing Meraki MX licence. It is available in one-year, three-year, and five-year terms, with longer terms offering better per-year pricing. The licence is applied per MX appliance, so you can selectively enable it at your most critical sites if budget is a concern.

Hardware requirements are minimal — any current-generation MX appliance supports Insight. The only prerequisite is that the MX is running firmware version 15.x or later, which should already be the case for any actively managed deployment. There is no on-premises server, no database to maintain, and no additional bandwidth overhead.

Best Practices for UK Deployments

Based on our experience deploying Meraki Insight across hundreds of UK sites, here are the best practices we recommend.

First, establish baselines before acting. Allow Insight to collect at least two weeks of data before making network changes. This gives you a reliable baseline against which to measure improvements. Second, focus on business-critical applications. Do not try to monitor everything at once — start with the five applications that matter most to your organisation and expand as needed.

Third, integrate alerts with your IT service management platform. Insight webhooks can create tickets automatically in ServiceNow, Freshservice, or Jira Service Management, ensuring that no degradation goes unnoticed. Fourth, review Insight data during regular IT operations meetings. The trending data provides valuable input for capacity planning, ISP negotiations, and technology refresh decisions.

Finally, use Insight data when negotiating with ISPs. If your broadband provider is consistently failing to meet their SLA during business hours, Insight gives you the evidence to support your case — or to justify switching to a competitor.

Real-World Use Cases

Retail Chain with 150 UK Stores

A national UK retailer with 150 stores was experiencing intermittent issues with their cloud-based EPOS system. Transactions would occasionally time out, causing frustration for staff and customers alike. Traditional monitoring showed healthy network links at every site. Meraki Insight revealed that the EPOS application's server response time was spiking during peak shopping hours (12:00–14:00 and 16:00–18:00), particularly at stores served by a specific regional ISP. Armed with this data, the retailer was able to work with the ISP to resolve a congestion issue at a regional peering point.

Professional Services Firm with Five UK Offices

A law firm with offices in London, Manchester, Birmingham, Edinburgh, and Cardiff relied heavily on a cloud-based document management system. Users in Edinburgh consistently reported slower performance. Insight showed that the Edinburgh office's primary broadband link had 15 milliseconds higher latency to the application server compared to other sites. The firm switched to a leased line at the Edinburgh office, and Insight confirmed the immediate improvement in application health scores.

NHS Trust with Multiple Sites

An NHS trust with six sites across the Midlands used Meraki Insight to monitor access to their electronic patient record system. Insight's proactive alerting detected a gradual increase in WAN latency at one site two weeks before it would have impacted clinical workflows. The trust's IT team investigated and discovered a misconfigured QoS policy that was allowing bulk data transfers to consume bandwidth during business hours. The fix was applied before any clinician experienced an issue.

Insight vs Third-Party Monitoring Tools

You might wonder whether you need Insight if you already use a third-party monitoring tool like PRTG, Zabbix, or Datadog. These tools excel at infrastructure monitoring — server CPU usage, disk space, service availability — but they typically lack the application-level, path-aware analysis that Insight provides. Insight is not a replacement for infrastructure monitoring; it is a complementary layer that focuses specifically on the user experience of network-dependent applications.

The key advantage of Insight is its native integration with the Meraki platform. There is no data export, no API configuration, and no separate login required. Everything is in the same dashboard your team already uses for switch, wireless, and security management. For lean IT teams — which describes most UK SMEs — this simplicity is a significant benefit.

Getting Started

If you are already running Meraki MX appliances, adding Insight is straightforward. Contact your Meraki partner to add Insight licences to your existing deployment. If you are evaluating Meraki for the first time, Insight is one of the strongest arguments for the platform — it provides a level of application visibility that would otherwise require significant investment in separate monitoring tools.

We recommend starting with a pilot at your busiest or most problematic site. Within a few weeks, you will have actionable data that demonstrates the value of the platform and builds the business case for a wider rollout.
