The Analytics System dashboards display information about the health and activity of Versa Operating SystemTM (VOSTM) devices.

This article describes the Analytics System dashboards, which are located at Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > System:

  • Top-level system dashboard—Displays device loads, anomalies, log counts, and search log statistics
  • Interfaces—Displays statistics for the device's WAN, LTE, and WiFi interface statistics
  • Guest VNF—Displays universal CPE (uCPE) health information
  • SNG—Displays service node groups statistics
  • Measurements—Displays statistics from the Two-Way active Measurement Protocol (TWAMP)

For general information about how to use an Analytics dashboard, see View Analytics Dashboards and Log Screens.

Top-Level System Dashboard

VOS devices forward logs to Analytics nodes, and the Analytics node use these logs to monitor and display the health and activity of each VOS device. To view the Analytics dashboards related to VOS device health, select Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > System. The following screen displays.

System_Tab_Top_Level_Screen.png

The top-level System dashboard has the following tabs in the horizontal menu bar:

  • Appliance Health
  • Appliance Activity
  • Appliance Anomalies
  • Search Logs Activity

Appliance Health Tab

The Appliance Health tab displays the Appliance Health Monitoring table. This table provides current system load information for a VOS device, including near real-time CPU, system memory, disk, and sessions usage.

System_Tab_Top_Level_Screen.png

In the Appliance Health Monitoring table, you can drill down on a VOS device to display the following charts, which display information about the load over time:

  • Appliance Monitoring by CPU Load
  • Appliance Monitoring by Memory Load
  • Appliance Monitoring by Disk Load
  • Appliance Monitoring by Sessions Load

Appliance Activity Tab

The Appliance Activity tab displays log counts for tenant VOS devices.

System_Main_Appliance_activity_tab.png

Appliance Anomalies Tab

The Appliance Anomalies tab displays anomaly information for tenant VOS devices.

System_Appliance-anomalies_tab_fullsize.png
In the Appliance Anomalies table, you can drill down on a VOS device to display the following charts, which provide details about the anomaly:

  • device Monitoring by CPU Load Exceeded
  • device Monitoring by Memory Load Exceeded
  • device Monitoring by Packet Buffer (mbuf) Depletion
  • device Monitoring by Service Load Exceeded
  • device Monitoring by Session Load Exceeded
  • device Monitoring by Worker Thread Busy (Lcore Detection)

Search Logs Activity Tab

The Search Logs Activity tab displays search log activity information for the selected tenant. On this screen, logs are identified either by the VOS device generating the logs, such as device Colovore-DC-Branch-1, or by the log's syslog identifier, such as cgnatLog or dnsfLog. For a list of syslog identifiers, see Analytics Log Collector Log Types Overview. The Search Logs Activity screen displays the following charts:

  • Logs Features Distribution
  • Search Logs per Appliance
  • Total Search Logs

System_Search-Logs-Activity_tab_fullsize.png

To display log distribution information for a VOS device, drill down on an individual VOS device in the Search Logs per Appliance chart. The following screen displays:

System Interfaces Dashboard

To view information about the WAN, LTE, and WiFi interfaces on a tenant's VOS devices, select Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > System > Interfaces.

System_Interfaces_Main_Dashboard.png

The System Interfaces dashboard has the following tabs in the horizontal menu bar:

  • WAN Interfaces
  • LTE Interfaces
  • WiFi Interfaces

WAN Interfaces Tab

The WAN Interfaces tab displays WAN utilization and statistics, showing the following items:

  • WAN Utilization Over Time
  • WAN Statistics


System_Interfaces_WAN_tab.png

To display WAN utilization statistics for a site, in the WAN Statistics table, select the Zoom icon to the left of the site name.

LTE Interfaces Tab

The LTE Interfaces tab displays LTE statistics and status information for VOS devices that have LTE interfaces.

System_interfaces_LTE_top_dashboards.png

To display detailed LTE statistics for a VOS device, select the Zoom icon to the left of the VOS device name.

WiFi Interfaces Tab

For Releases 21.2.1 and later.

The WiFi Interfaces tab displays the VOS devices and connected clients for a tenant for a specified time range. For multitenant devices, this information is part of the provider organization.

System_interfaces_wifi_top_level_dashboard.png

To display WiFi usage details for a VOS device, drill down on a VOS device name.

System_interfaces_wifi_appliance_drilldown.png

To display client statistics for a MAC address, in the WiFi Usage Statistics for device table, click the Zoom icon to the left of the MAC address.

Tunnels Tab

For Releases 22.1.1 and later.

The Tunnels tab displays IPsec tunnel statistics.

System Guest VNF Dashboard (Universal CPE)

A VOS device can host multiple guest VNFs (also called universal CPEs, or uCPEs). Traffic can be service-chained through guest VNFs. To view summary information about uCPE devices, select Analytics > Home > Dashboards > System > Guest VNF. The System Guest VNF dashboard displays the following charts:

  • Guest VNF Health Monitoring
  • Guest VNF Interface Statistics
  • Guest VNF Events Logs

    249.png

To display the topology view and system status and statistics of the VNFs running on a VOS device, click the Zoom icon to the left of a specific VNF.

System Service Node Groups Dashboard

Service node groups (SNGs) are associated with each guest VNF. A service chain instance ID (SCID) defines group of SNGs. The VOS devices hosting the guest VNFs use the service chain instance to steer traffic through the SNGs.

To display information about the traffic flowing through a service chain or service node groups, select Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > System > SNG.

251.png

To view information about forward and reverse traffic flows, click the Zoom icon on a specific row.

System Measurements Dashboard

For Releases 21.2.1 and later.

VOS devices use the Two-Way Active Measurement Protocol (TWAMP), defined in RFC 5357, to measure metrics such as delay, delay variation, and loss between two IP endpoints that support the TWAMP sender and receiver functionalities. The metrics are exported to Analytics nodes. The Analytics > Dashboard (Home) Dashboard_icon.png > Dashboards > System > Measurements dashboard displays the TWAMP metrics per IP session for a tenant or VOS device.

The System Measurements dashboard displays the Two-Way Active Measurements Protocol table:

To view the details about a VOS device in a time-based bar graph, click the Zoom icon to the left of the VOS device.
