Monitoring network applications
Network applications in Nexthink help you identify issues such as network congestion, server unavailability, misconfiguration, or security restrictions. Monitor various connection-based services like mail, VPN, and directory services.
From the chosen network application dashboard, view and filter important metrics specific to a desktop application using:
The Overview tab includes widgets for connectivity performance, failure trends, traffic volume, and device activity across the network.
The Network tab has a visualization of
connection.eventsdata and metrics specific to the Network application. Refer to the Network view to interpret this visualization.
The Overview tab for Network applications only includes Transmission Control Protocol (TCP) event data.
To monitor User Datagram Protocol (UDP) events for this application, navigate to the Network tab, select the Total number of connections metric, and click the UDP button in the Network view.
Assessing connection patterns of network applications
From the target network application dashboard, explore the widgets under the Overview tab to understand connectivity performance, failure trends, traffic volume, and device activity across the network:
Connection establishment time
Connection establishment time represents the average round trip time (RTT) for all established connections. A high connection establishment time suggests delays, possibly due to network congestion, server load, or the distance between client and server.
Identify devices with notably long connection establishment times (>100ms) through smart drill-downs, accessible via the kebab menu next to each metric.
The line chart displays recent changes in the metric.
Failed connections
The Failed connections metric represents the sum of rejected, no host and no service connections. It signifies the inability to establish communication between client and server, typically due to issues such as network congestion, server unavailability, misconfiguration or security restrictions. These failures can potentially result in service disruptions, data loss or degraded user experience.
The Devices with high percentage of failed connections (>10%) metric helps you assess the impact of failed connections on devices in your environment.
The line chart displays the number of failed connections per failure type over time. Click on the legend below the chart to toggle visibility of different failed connection types. Total represents the cumulative count of all types.
Traffic
Monitor incoming and outgoing traffic to grasp the network's overall activity in terms of data volume.
High Incoming traffic may signal popular content or heavy server load.
Elevated Outgoing traffic may imply active user interactions or data uploads.
Use the line chart to scrutinize sudden spikes or irregular traffic patterns, potentially indicating suspicious behavior.
Dashboard Breakdowns
Use the widgets under the Breakdowns section to analyze metric variations by destinations, organization, and other breakdowns.
Switch tabs to see breakdowns by different properties.
Click on a table header to sort by available metrics.
Click on a row in the table to filter the page for the selected element.
Access the underlying NQL investigation of each visualization via the kebab menu in the top-right corner of the widget group.
The Organization table displays metrics by your organization's classification. Select the organization level from the dropdown list.
Refer to the Product configuration documentation for more information on how to define entities and custom classification for your organization.
Consider the following differences:
The Country tab under Destinations represents the location of the destination point based on GeoIP information.
The Country tab under Other breakdowns indicates the location of the device when the system captures the connection.
