Catchpoint's Node Smartboard is designed to help you isolate performance issues detected by specific Nodes.
Let's look closer at each of the sections in the Node Smartboard.
Source
This is the specific Node whose data is being rendered in the Smartboard. You can change the source by clicking on the "Source" button in the upper left, then selecting the desired data source. When you make a selection, the Smartboard refreshes all sections with data from the new source.
Timeline
The Node Smartboard begins with an interactive timeline at the top of the page. This timeline displays the following four types of informaton about the selected Node:
- Experience Score - the blue line represents the average Experience Score for all tests run on the Node at each point in time.
- Downtime - The verticle bars represent downtime, or the percentage of test runs that received no response.
- Warning Alert - any alerts that trigger based on a Warning threshold will be indicated in orange.
- Critical Alert - any alerts that trigger based on a Critical threshold will be indicated in red.
Time Window Selection
All graphs and tables displayed in the Smartboard are generated using test data from within your selected time window (last hour by default.) You can select a different time window by clicking the field at the top left and selecting the desired timeframe, or by clicking and dragging the edges of the shaded area in the Timeline to the desired starting and ending times. When you make a new selection, the other sections refresh with data from the new time window.
Tests Tab
The Nodes Smartboard is divided into two main tabs. The Tests Tab provides the following information about the selected Node:
Summary Information
Below the timeline you'll see a row of items with summary information about the Node and its test performance, including the following:
Experience Score
This is a gauge with the Node's Experience Score. This value represents the average score for all runs executed during the selected timeframe, and provides a quick summary of overall test performance from the node.
Errors
This is a count of errors of each type that occurred during the selected timeframe.
Node Information
This is a listing of basic details about the selected node.
- Node Type - the type of node, as determined by the network the node connects to (e.g. Backbone, Wireless, Enterprise, etc.)
- Location - the geographic location of the node
- OS Version - the operating system running on the node
- Model - the model number of the node. The numeric value indicates the number of browser-based tests each instance can run simultaneously.
- Instances - the number of individual machines (physical or virtual) that constitute the node.
- Capacity - the total number of browser-based tests that the node can run at one time, calculated by multiplying the numeric portion of the model number by the number of instances.
- Package - the name of the package assigned to the node, which determines which monitor types the node is licensed to run.
Test Performance
This table displays the tests that were run by the node during the selected timeframe. It displays each test's name, the average Test Time during the selected time window, and its % Availability during the selected time window. The tests are displayed using color-coded tiles by default, and you can use the "View" selector on the right to change to a simple list view.
Network Tab
By clicking Network at the top of the Smartboard, you can access the network tab which displays the following information:
Network Table
A list of ASNs, Hop IPs, and Destination IPs from the network paths for all tests run during the selected timeframe, with details about their performance characteristics such as RTT, packet loss, and jitter. This table helps you see which specific ASNs or network nodes may be contributing to test performance issues.
Network Graphs
A graphical view of the ASN and IP network paths for all test runs during the selected timeframe. You can use the timeline and filtering options in the graph to zero in on specific test runs with performance issues and see what network paths they traversed.
