Data Flow gives you a big-picture view of how your infrastructure works. It provides a visual display of the network connections between all the servers in your infrastructure.
Getting Started: Selecting your view using Server Groups or Server Tags
Server Groups allows you to view a specific view of your infrastructure that you’d like to investigate in a sensible way. Selecting a Server Group from the top drop-down menu allows you to explore Data Flow by focusing on only the servers from the selected Server Group. You can reselect which Server Group you would like to view from any page or simply choose “All” to see all of your servers. Please note that if the “All” selection results in too many servers to display, you may need to narrow down the server group.
Working with Data Flow
To start, select the time range you want to view at the top of the graph (Recent Minute, Last 5 Minutes, Minute At, Hour At).
The graph shows, for the selected time range, how much traffic flow there has been between any two servers in either direction. This is represented with colored circles and lines. Each circle represents a server. The color of each circle will change according to the server’s average response time. A standard light blue color means the average response time is low, while a darker blue, brown, or orange color means the average response time is high. The lines represent connections. The thicker the line is, the higher average response time. The three different colors lines represent three different connection types.
- Green lines are Client connections
- Blue lines are Server connections
- Grey lines means we detect a client/server connection but there is no data to show
Hovering over a circle will display the server’s average response time. Hovering over a line will display details about the network connection, including the average response time for transactions, and the total amount of data flowing in either direction.
Clicking on a circle will pull up the most recent performance data of that server.
What to do next with this Data
When you click on a server, you can see all the processes running and their resource utilization. If you’re looking at a server and find a process with a high average response time, for example, you can click on the process itself in the popup list to bring it up in correlate. This allows you to bring up a detailed view of the resource utilization history over a selected length of time.
When you’re monitoring infrastructure performance, it can be easy to get caught up in small details. Data Flow shows you those small details, while also giving you the big picture view of how your infrastructure works.
