Why is network observability important?
The size and complexity of networks are increasing, and user expectations are also skyrocketing. Organizations need a system that can effectively communicate and state what needs to be fixed. Let's learn about the challenges in today's networks, and see how network observability can help.
Blended networks
Most global organizations own a dedicated on-premises network in addition to several cloud-based networks like Cisco Meraki or VMware NSXs. Even though monitoring tracks availability, traffic patterns, latency, bandwidth, packet loss, and other similar metrics for all the devices, collecting the data requires different methods like SNMP, WMI, or REST API, depending on the device, or the type of network being monitored. This means a network monitoring tool should adapt to monitor blended networks.
Interconnected components
Modern applications often consist of connected components distributed across multiple systems, which adds layers of complexity and increases the likelihood of failures. Continuous monitoring requires collecting metrics to detect anomalies. However, observability makes spotting deviations clearer by aggregating all data on a single pane, making the identification of anomalies easier across a distributed architecture.
Increased cyberthreats
Traditional network monitoring help establish baselines and monitor metrics, but fails to provide the necessary insights to troubleshoot issues. Simply receiving alerts means that existing systems inform you that there's an issue, but they do not provide any warning before a problem arises. In a more serious scenario, a vulnerability in any of the devices might go unnoticed, causing a small issue that could lead to significant downtime, affecting both customers and employees. Furthermore, cybercriminals might exploit vulnerabilities in the system without the network administrator's knowledge. In large and complex systems, a monitoring dashboard might help track issues, but it might not necessarily assist in proactively identifying problems.
Insights into network performance
Basic monitoring of network infrastructure can only provide limited insights into the network's performance. Network observability, on the other hand, goes beyond basic monitoring by collecting and analyzing vast amounts of data from various sources within the network infrastructure. This comprehensive visibility allows organizations to detect proactively and address performance issues, security vulnerabilities, and other network-related challenges before they have any negative impact on their businesses. In other words, network observability provides a big-picture view across network components, applications, and cloud systems, enabling organizations to gain deeper insights and make informed decisions.
Monitoring fatigue
Network monitoring is vital for complete visibility, where network admins establish baseline behavior and receive alerts from monitoring tools if there's any deviation from expected behavior. However, constantly looking at dashboards and metrics can cause network admins to miss some issues due to fatigue, leading to suboptimal network operation over time. Every day, billions of metrics are generated, which is overwhelming, but businesses only need to know if the user flow works as expected without any hitch.
Network observability, on the other hand, focuses on the end-user experience. With an observability solution in place, network admins receive proactive information if any action does not work as intended due to any issue within their network. They can then inform customers beforehand, helping businesses maintain trust and prevent any potential loss of revenue.
Data-driven decision-making
Monitoring a network can be a challenging task for admins, since they have to track scattered metrics from different modules to gain a complete picture of the network's performance. Unfortunately, this process tends to slow down decision-making.
By implementing network observability, administrators can effectively analyze and monitor network performance, which empowers them to make informed decisions about network management and optimization. By analyzing data, they can identify trends, patterns, and performance indicators to improve network efficiency and reduce costs. The actionable insights they get from network observability enable well-informed decision-making, which is crucial for enhancing overall business outcomes.

Network observability vs. network monitoring: What's the difference?
| Network monitoring | Network observability | |
|---|---|---|
| Data collection | Basics like uptime, bandwidth utilization, and device availability | Comprehensive from various sources like flows, packets, and telemetry |
| Threshold and alerting | Predefined thresholds | ML and anomaly detection |
| Incident response | Reactive | Proactive |
| Application and user performance metrics | Limited visibility | Holistic view |
| Data analysis | Lacks real-time data analysis | Employs real-time data analysis for quick identification and troubleshooting of issues |
What are the key elements of network observability?
Effective network operations triage requires teams to gather intelligence from various sources like alarms, network flows, performance data, network configurations, and logs. Only with complete operational visibility can teams make quick, intelligent decisions and identify the root cause quickly. Troubleshooting becomes easy when teams gain visibility into the user experience. They can even troubleshoot in the context of a specific network device, interface, or virtual network function.
Solutions that collect relevant data formats and data streams enable organizations to focus on what matters, and avoid spending hours searching for the proverbial needle in the haystack in today's networks. Network monitoring software should help administrators by providing them with the necessary tools to quickly identify and resolve issues, instead of adding to the time it takes to triage problems. The goal should be to reduce the need for escalations and empower admins to efficiently manage the network. Missing even a single ingredient of this recipe could mean that the root cause remains hidden for hours or even days, leading to blame games within teams, and a potential compromise to security.

After data collection, advanced analytics techniques are applied to extract insights.
-
Machine learning algorithms
Analyzing network behavior to find patterns and trends, identifying any deviations from normal behavior, and anticipating possible problems.
-
Statistical analysis
Setting baselines, determining appropriate thresholds, and identifying any deviations from expected performance.
-
Anomaly detection
Automating the detection of unusual or suspicious network events that could indicate potential security threats, or performance issues.

Alerting mechanisms send alarms when specific thresholds are breached, or anomalies are detected. This helps network teams respond proactively to incidents, ultimately reducing the time taken to troubleshoot and resolve network issues, resulting in minimal impact on business operations, ensuring that everything runs smoothly.
What are some network observability use cases?
Consider a banking organization, Zylker, that faces a payment failure. Even one minute of outage could leave thousands of customers in the lurch as they try to complete their transactions. With a monitoring solution in place, the bank staff receives an alert on the system failure which could be because of any network issue like high traffic, poor bandwidth allocation, or a device failure. Here, we will take the case of a router that is not responding as there are incorrect configuration changes.
Identify root cause :
With an AI-powered observability solution in place, network admins will view information about any unusual spikes or anomalies in the device's critical performance attributes like response time, CPU usage, or memory utilization. As they drill down, the network admins analyze the reasons for it.- Detect and resolve network bottlenecks, latency issues, or bandwidth constraints before they impact user experience.
- Monitor network metrics, such as packet loss, latency, and throughput, to optimize network performance.
Detect and respond to security threats :
On the dashboard, the network admins will be able to view that there's an unapproved configuration change. They can then quickly revert the last working configuration file and ensure that the router continues to operate without any glitches. This minimizes the impact, significantly decreases security risks, and eliminates unplanned downtime.- Detect and respond to security threats, such as malware, intrusions, or unauthorized access attempts, in real time.
- Monitor network traffic patterns and anomalies to identify potential security breaches or unusual behavior.
Generating automated insights about network malfunctioning :
As the solution "learns" about possible cases of network failures, it will generate automated insights and might also provide recommendations. This might include forecasts based on current usage patterns.- Quickly diagnose and troubleshoot network problems by analyzing real-time data and identifying causes.
- Provide recommendations and forecasts that help in capacity planning.
Diagnose and troubleshoot network issues :
Network issues could be caused by device hardware, firmware, device configuration, or even improper bandwidth allocation. A holistic view that includes a network map helps network admins understand what fixes must be applied to prevent the same issue from recurring.- Visualize network topology and traffic flows to pinpoint issues, reduce downtime, and minimize service disruptions.
- Diagnose the problem to prevent recurrence.
Gain insights into application behavior and performance :
An application's slowness might also be caused by a network issue. If Zylker uses only an application monitoring tool but does not monitor networks, it might be impossible to troubleshoot the issue. However, with a network observability solution in place, network admins gain insights into application performance and address issues.- Gain insights into application behavior and performance by monitoring network traffic and application-specific metrics.
- Identify and address issues related to application responsiveness, data transfers, or service dependencies.
Compliance and Regulatory Requirements :
Every organization needs to ensure that there are rules and policies to defend its networks from potential threats and ensure compliance with industry standards like Cisco IOS, SOX, HIPAA, PCI, or any other custom organizational policies. Failing to do so might result in serious repercussions. The right way to approach this is to have a network observability solution that also includes a compliance module.- Monitor network activity and capture relevant data to ensure compliance with industry regulations and data protection standards.
- Maintain audit trails and generate compliance reports for regulatory purposes.
How can network observability be implemented?
Organizations with a sound network monitoring foundation are better positioned to reinvent, compete, and implement observability solutions with minimal disruption. If an organization doesn't have a monitoring solution yet, implementing a secure, cloud-based network monitoring platform first helps steer it toward network observability easily and achieve more significant growth, efficiency, and resilience.
Here are the steps organizations take to move toward complete observability:
