Getting Started with ELK¶
NetEye.Cloud includes Log Analytics, which is based on the Elastic Stack. Elasticsearch stores and indexes the data collected from your environment, such as logs, metrics and traces. Kibana is the interface you use to work with that data. This chapter explains how to open Log Analytics and how its features are organized, so you know where to go for each task. Each feature has its own chapter with more detail.
Opening Log Analytics¶
Log in to NetEye.Cloud (https://neteye.cloud). On the start screen, click
Log Analytics, which opens Kibana on the Log Analytics home page.
Fig. 223 Log Analytics home page¶
The home page shows the two main areas of Log Analytics: Analytics and
Observability. Click either one to open it. To go straight to a specific
feature, open the in the top left corner. It lists the features of
each area.
The two areas use the same data but for different purposes. In Analytics, you explore the data and present it: you search, filter, aggregate and visualize it. Observability is organized around the systems, applications and services you monitor. It shows their health and performance and helps you troubleshoot them. In daily work you’ll often use both. For example, you might notice a problem in Observability and then look at the underlying data in more detail in Analytics.
Tip
Most views include a time range selector. The data you see always depends on the selected period. If a view shows less data than you expect, check the time range first.
Analytics¶
Analytics is where you turn the data collected in Elasticsearch into information you can read and interpret. You use it to search for events, logs, metrics and other indexed data, and to filter them by time range, field or value. You can also look at trends, distributions and comparisons, and build the charts, tables and dashboards used for analysis and reporting.
Discover is usually your starting point. It gives you direct access to the raw data stored in Elasticsearch. You can look at individual records, inspect their fields and apply filters to narrow the results. You can also follow how events are distributed over the selected time range. Use Discover for quick investigations, for example to check whether a specific event was recorded. It also helps you understand what an index contains before you build anything on top of it.
Visualize Library is where you create and manage visualizations, such as charts, tables and metrics. Visualizations are saved in the library, so you can reuse the same one in several places instead of rebuilding it. This also keeps the way data is presented consistent across your team.
Dashboards combine several visualizations into a single view, together with filters that apply to the whole page. A dashboard shows the most important information about a topic in one place, such as a service, a group of hosts or a business process. This makes dashboards the usual tool for recurring monitoring and for sharing a common view within a team.
Canvas is for building workpads, which are free-form pages that combine live data, charts, text, images and other visual elements. Dashboards follow a grid structure, but Canvas lets you control the layout and appearance in detail. This makes it a better fit for presentation-oriented output, such as a status screen or a report.
Maps displays data that has a geographic component on interactive maps. You can place events, assets or metrics by location and analyze how they are distributed across regions, sites or specific areas.
Graph helps you explore relationships between entities in your data. It shows how values in different fields or records are connected. This is useful when you’re looking for links that aren’t visible in a list of events, for example between users, hosts and addresses involved in the same activity.
Machine Learning detects anomalies and unusual patterns in your data. It highlights behavior that differs from the norm, so you can notice issues or unexpected trends that a fixed threshold wouldn’t catch.
Observability¶
Observability is meant for monitoring systems, applications and services. It brings together logs, metrics and traces from applications and infrastructure, so you can look at the health, performance and availability of a service in one place. You can also correlate information from different sources. This makes it easier to find errors, slowdowns and anomalies, and to work out their cause.
Overview summarizes the whole observability environment. It shows the health, performance and status of your systems and applications at a high level. Use it to quickly see whether anything needs attention before you go into a specific area.
Logs gives you central access to application and infrastructure logs. You can search, filter and inspect log entries to find errors and see what happened around a specific event. This is often where troubleshooting starts once you know roughly when and where a problem happened.
Infrastructure is about hosts, containers and other infrastructure resources. It shows metrics such as CPU, memory, disk and network usage. These help you find bottlenecks and unusual system behavior, and decide whether a problem comes from the underlying resources.
Applications covers application performance monitoring. It shows response times, failures and throughput for your services, and how the services depend on each other. When an application is slow or returns errors, this view helps you find the service where the problem starts.
User Experience looks at how real users interact with your applications. It covers aspects such as page load times and frontend responsiveness. Use it to find issues that affect end users, even when the backend looks healthy.
Synthetics checks the availability and behavior of services with simulated tests. It checks whether websites, APIs or endpoints are reachable and respond as expected from the user’s point of view. Because the tests run independently of real traffic, you can detect a problem even when no user has been affected yet.
Alerts lists the alerts triggered by the rules defined in your environment. You can follow the warnings and incidents these rules generate and respond to them promptly.
Cases is for organizing and tracking incidents and operational issues. In a case, you document the problem, add comments, assign actions and follow the resolution step by step. This is useful when several people work on the same issue.
SLOs (Service Level Objectives) track whether your services meet their reliability or performance targets, such as availability or response time goals. Alerts and Cases are about individual incidents. SLOs show how a service performs against its targets over time.
Roles and Permissions¶
The ELK contract defines three roles: VIEWER, EDITOR and ADMIN. Your role determines which operations you can perform in Kibana. You can perform only the operations your role allows.
Roles are assigned to users or groups, depending on the authentication and profiling method configured in NetEye. Each feature chapter lists the role it requires in its Roles and permissions section.
Note
If a feature or action described in this guide isn’t available to you, ask your NetEye.Cloud administrator to check your role.
