More Product Updates

February 2021

Kentik’s product and engineering teams continue to deliver the new capabilities and features that matter the most to our customers, driven by the valuable feedback that we collect. Here is a summary of new features as well a more detailed description with relevant screen captures below.

February 2021 Summary

Kentik’s product and engineering teams continued rapid iteration on Kentik Synthetics. The mesh test display has been greatly enhanced to handle large meshes, and synthetics widgets are now available for dashboards and My Kentik Portal. Flow-based traffic data has also been added to mesh test results. This builds on Kentik’s unique combination of synthetics and real traffic information to help our customers easily choose and set up the right tests.

We’ve also added a number of new traffic comparison insights looking for traffic volume changes, changes in volume for cloud services and regions, and changes in OTT dynamics.

On the DDoS front, we’ve delivered a number of improvements requested by customers. Some are focused on better visibility into mitigation actions and others on usability improvements for policy configuration and alert history.

Synthetics

The product and engineering teams continue to deliver exciting new enhancements and features. Here are some of the latest.

Dashboard Widgets and My Kentik Portal Support

Kentik customers now have the option of adding synthetics test results as widgets to their Kentik dashboards and then sharing those widgets with their customers (tenants) via My Kentik Portal. Custom dashboards also let you visualize real traffic charts alongside synthetic test results to help you easily correlate test failures with changes in real traffic patterns.

  • Editing any existing dashboard will show users an option to add “Synthetic Test View.”
  • Clicking Add will show a modal that allows users to select a synthetic test from the list of tests configured in the account.
  • If the selected test happens to be a mesh test, the user has the option of choosing to have the widget either show a mesh or a table of results.

High Density Meshes and Mesh Improvements

The mesh tests are a very popular feature and we continue to respond to the most common UX enhancement requests. We’ve made the following improvements:

  • For very large meshes, we’ve added dynamic horizontal and vertical scrollbars when the mesh gets beyond a certain size.
  • For “Network Performance Meshes” shown in the Synthetics Performance Dashboard, a label has been added to clearly indicate the 15-minute range. Clicking the link propagates the 15-minute time range so that the test results page shows the same results as the performance dashboard.
  • The “Customize” button has been renamed to “Show/Hide” for clarity
  • We increased the string length for labels on the left and top edges of the meshes that represented sites to allow the strings to be longer and wrap across multiple lines so as to let users determine which paths/routes are failing with a quick glance of the mesh.
  • Hovering over the individual cells of a mesh would show location information as city, state, country, which is not easily actionable when testing between public cloud regions or private sites. This is now enhanced with both pieces of information.
  • The Cloud Performance preset meshes are well-received. We improved the UX around parsing their information as well as customization:
    • We added the ability to easily clone them (like the SaaS applications), which allows customers to customize them to make a "yybrid-cloud" mesh out of it for their own specific network performance needs.
    • We also show cloud regions in addition to geo (city/state) information in the labels to the left and the top.

Flow Data in Mesh Test Results

Showing real traffic time-series charts alongside synthetics metrics in the test details is an important feature, but this wasn’t possible to do for site-to-site tests (like agent-to-agent tests or mesh tests) because there was no IP to query based on. We solved this by leveraging the new site-IP configuration that was added to the device configuration. If a site-IP is present it will be used to build the traffic chart and allow the user to jump into Data Explorer to slice and dice the data further.

General Improvements

Several general improvements to the UX have been made in response to customer feedback:

  • The workflow to find a failing sub-test’s details (the time-series charts) is simplified by making the agent dots on the map clickable. Clicking them now takes you to the test details:
  • Defining and assigning a notification channel in the test creation screen is much more intuitive than it was before:
  • It wasn’t clear to users that it takes a while (up to a day) for IP changes to reflect. We added a tooltip for this:
  • The point where the day changed on the test timeline was not clear — this is improved visually. Also, the date format shown in the selector now matches the format of the date shown on the timeline:
  • The agent version for customer’s private agents is now visible to them. Also, checking a customer’s private agents’ IPs and versions is simplified — the agents’ information is readily available in the table:
  • Paused tests now show in historical data.
  • Test results legend previously said “ICMP could be blocked.” This has been generalized, as the test could be TCP or UDP.

Insights

Insights are a unique feature provided by Kentik. They are autonomous notices that tell you about interesting or anomalous behaviors. Insights can be any fact that is relevant to the traffic at which you are looking. Insights help you quickly recognize where there might be a problem that requires your attention.

New Comparison Insights

We are releasing a number of new comparison insights for Cloud, Edge, and Service Provider dimensions. These have been introduced in conjunction with the comparison threshold improvements (explained below). Please also see the Knowledge Base documentation.

DDoS

Kentik DDoS detection leverages network analytics and insights to deliver a detailed picture of your traffic, serving to identify and mitigate DDoS attacks in real time. This service protects organizations’ networks and ensures business continuity.

We’ve made a number of improvements to v4 DDoS detection and policies:

  • The mitigation list in v4 now shows all mitigations, regardless of whether they were triggered by v3 or v4 policies.
  • Mitigation list now includes the mitigation ID.
  • Alerts and mitigations are now cross-referenced. Alert summaries and details show any related mitigations and vice versa.
  • Configured thresholds are now displayed immediately in the policy configuration. Previously, thresholds were displayed only after the graph finished loading.
  • Thresholds must now be configured in order (i.e. “critical” must have higher threshold values than “major”).
  • Threshold lines on the graph now use colors with more contrast to make them easier to distinguish.
  • General cleanup and bug fixes in policy configuration, including IP exclusions
  • DDoS alert log is now searchable by multiple dimensions, including full or partial key values.
