Network latency

The Network latency response times insight lets you see which IP addresses or domains have the longest response time or don’t respond at all to device requests. This data can help you troubleshoot possible issues related to the application server, for various device groups across the organization.

Main tile view

The main tile view provides a table of the top 5 IP addresses or website names that take the longest to respond to device requests.

In the IP/DNS column, you can click the IP address or DNS to get a drill-down view of the latency data. In the Test type and Response time columns, you’ll see the type of request made and the total response time in milliseconds respectively.

If you defined a Related app in the Settings > NETWORK tab, you can also see which apps had the longest response times when you hover your cursor over a value in the Response time column.

Clicking any IP address or domain name takes you to the Network latency drill-down view.

Drill-down view

The drill-down view provides two charts to help you analyze network latency trends:

• Average latency trend
• Total latency trend

Above the charts, you’ll see a ribbon displaying key network latency information.

This ribbon provides the following information:

Average latency trend

The AVERAGE LATENCY TEST RESPONSE TIME TREND chart lets you see the average time it takes (in milliseconds) to respond to the particular address over the requested data period. Hover your cursor over the graph to view detailed information like the total test count, and average/median/max latency times for each day.

Total latency trend

The TOTAL LATENCY TEST COUNTS ABOVE THRESHOLD chart lets you see the total number of times a query took too long to respond — or didn’t respond at all — based on the pre-defined latency response time thresholds.

Depending on the type of latency test you’re conducting (PING, DNS, or TCP), the following values define the lower and upper thresholds for the chart:

Hover your cursor over a graph to view the total number of delayed-response or no-response issues per day.

Towards the bottom of the chart, you’ll find a legend that color-codes the different trend graphs for No response, Lower threshold, and Upper threshold respectively. Click any item in the legend to show or hide the graph on the chart.

Response time per group

In the RESPONSE TIME PER GROUP data table below, you’ll see a summary of your device groups’ network latency data. In the ACTIONS drop-down, you can download a CSV file of the network latency data for groups in your fleet, or for devices in a specific group.

Download CSV file for groups in your fleet

To download the CSV data for groups in the fleet, select one or more groups from the list, then click ACTIONS > Download as CSV. You can also perform this action without selecting a group. If no group is selected, the CSV file will contain data for all groups in the fleet. Once downloaded, the Network_response_time_group_list CSV file provides the same data set from the RESPONSE TIMES PER GROUP table.

Download CSV file for devices in a specific group

To download the CSV data for devices in a specific group, select a single group from the list, then click ACTIONS > Download device list as CSV.

Once downloaded, the Latency_response_time_device_list CSV file provides a data set different from the RESPONSE TIMES PER GROUP table. In this CSV file, you’ll get the following data:
