The dashboard presents you with a user-friendly summary of all sensor test results. Positive results are green, yellow indicates a warning and red means there were errors detected.
There are three views:
The default view of the dashboard displays the status of the user experience; a green happy face means everything is good and a sad face indicates an issue. You can also use this view to identify whether the issue is with a network service or application and which sensors are affected.
The Map view positions groups and sensors geographically.
The Brick view positions groups and sensors in a grid.
For the Map and Brick views, sensors with an issue are highlighted in red.
When examining the dashboard, you might also encounter a grey color which indicates Untested. There are usually two likely causes of something to be an untested state:
When an issue is encountered with the Core tests. If a Core test fails, the sensor will not perform internal and external tests for that SSID.
If the time between test results is larger than normal. This is usually due to the sensor detecting a failure of any test and going into triage mode to troubleshoot the issue. Triage mode can be a time-consuming process, resulting in the test cycle taking longer to complete and the measurements to be further apart.
This section will take you through the tools used to identifying and troubleshooting issues including:
Examining the icons and charts in the dashboard
Applying filters
Exploring the sensor status pages
Exploring the test results pages
Navigating triage mode
Applying Mutes
Examining the Icons and Charts in the Dashboard
Step 1: Go to the dashboard. Notice from a high level when an issue is detected, you can distinguish between wireless and ethernet issues.
Step 2: There are four columns in the dashboard.
The Experience column displays the status of the sensor groups or sensors.
The Services column displays the status of the network and network services.
The Internal and External columns display the status of the internal and external tests.
Step 3: The Experience column lists the sensor groups or the sensors if viewing within a group.
When you mouse over any group, you are presented with the following information.
When you mouse over any sensor, you are presented with the following information.
Step 4: You can drill-down to the sensors in the group by selecting the group name in the dashboard or using the navigation selection at the top of the screen. To go to the top level, select All Groups.
Step 5: In the Services column, mouse over Wi-Fi and ethernet.
You are presented with a list of SSIDs or Ethernet networks currently being tested. If looking at the Wi-Fi and ethernet networks from the group view you can identify how many sensors are configured to test each network.
Step 6: In the Services, Internal and External columns, mouse over the test results.
For the remaining tests in the Services, Internal and External columns of the dashboard, when you mouse over you can identify the sensor or group name, total number of alerts over the last 24 hours, the total number of sensors configured to conduct the test with a breakdown of how many sensors are testing successfully, producing warning messages, encountering errors and configured but untested.
Applying Filters
Filters are a powerful tool that allows you to drill-down to specific sensors in good, warning and error states, sensor groups, SSIDs or ethernet networks.
Step 7: Open the filter menu by pressing the 'f' key on your keyboard or select the filter icon in the top right corner.
Step 8: Filter by status, sensor group or network. Close the menu to apply the filter.
Step 9: Open the filters menu, select clear all and close the filter menu.
Exploring the Sensor Status Page
Step 10: You can drill-down to a specific network and see the following elements.
STATUS Time series view of the sensor status and lists of ongoing and resolved issues.
ACTIONS Administrators can download raw data for up to 18 months or download packet captures from the rolling 50 MB buffer.
ABOUT This section provides the sensor serial number, IP configuration and MAC address.
WI-FI ENVIRONMENT This section provides information on the detected SSIDs, Signal (RSSI), Channel, Width, Band, and AP BSSID. The sort, filter and search within this section allow you to quickly drill-down down to items of interest.
WIFI This section is only for Wi-Fi and shows the measured signal strength (RSSI), receive bitrate, frame retry rate, channel utilization, band, channel, BSSID, AP association time
ETHERNET This section is only for ethernet and shows the ethernet link mode.
NETWORK SERVICES This section shows the measured DHCP response time (if using DHCP), DNS lookup time, or captive portal load time (if applicable)
INTERNAL and EXTERNAL These sections provide the results of the internal or external tests such as latency, packet loss, jitter, HTTP GET, throughput (up and down), and VoIP MOS. Click "Expand +" to see the specific tests.
In the top right corner, you can apply filters or change the time range.
Step 11: Open the time range selection menu and view the last hour of data.
You can also enter a time and date within the last 30 days and select the time zone. When you click Apply, you can save these settings so you can quickly apply the time settings to other sensor status pages.
Close the time range menu when finished.
Exploring the Test Results Pages
Step 12: From the dashboard, select any of the test results in the Services, Internal and External columns.
All test results have a STATUS section with time-series view of the test and lists of ongoing and resolved issues.
Internal and External tests have an ABOUT section which described the test and a SERVICE column where you can see the test results. Click "Expand +" to see the specific sensors running the tests.
The Wi-Fi and Ethernet status pages display the Wi-Fi or ethernet metrics. Click "Expand +" to see the specific networks.
The DNS and DHCP test pages display the response times per DNS or DHCP server. Click "Expand +" to see the specific sensors.
Navigate Triage Mode
When the sensor detects an error performing a test, it will automatically attempt to root cause the problem with triage mode.
Note: Triage mode can be a time-consuming process and will slow down the overall test cycle.
Note: Errors generated by threshold violations do not have triage. Triage output is generated only for test failures.
Step 13: Navigate to a sensor status page and toggle to a network. In the STATUS section, locate an ongoing or resolved issue.
Notice the number represents how many times the error was encountered over the selected time period.
When you click on issues with triage output, you may see the following information if applicable:
Mutes
Once you know about an issue, you can mute the sensor or test on the dashboard by selecting the mute icon.
Step 14: You can add, edit or remove mutes by going to Settings -> Alerts -> Mutes and adding or editing a mute. Here you can also chose the time period and whether to mute warnings only or all alerts.
