Node graphs, at minimum, require a data frame describing the edges of the graph. This visualization needs a specific shape of the data to be returned from the data source in order to correctly display it. The marker next to the stat name shows which stat is currently used for sorting and sorting direction.Ĭlick on the node and select “Show in Graph layout” option to switch back to graph layout and focus on the selected node, to show it in context of the full graph. To sort the nodes, click on the stats inside the legend. Grid view shows nodes in a grid without edges and can be sorted by stats shown inside the node or by stats represented by the a colored border of the nodes. You can switch to the grid view to have a better overview of the most interesting nodes in the graph. You can click on the marker to expand the graph around that node. ![]() ![]() Nodes that are not currently visible are hidden behind clickable markers that show an approximate number of hidden nodes that are connected by a particular edge. The number of nodes shown at a given time is limited to maintain a reasonable visualization performance. Use the buttons in the upper left corner or use the mouse wheel, touchpad scroll, together with either Ctrl or Cmd key to zoom in or out. You can pan the view by clicking outside any node or edge and dragging your mouse. You can pan and zoom in or out a node graph. For more information, refer to the X-Ray plugin documentation. The first data source supporting this visualization is X-Ray data source for its Service map feature. Similar to nodes, you can open a context menu with additional details and links by clicking on the edge. There also can be additional links in the context menu that can target either other parts of Grafana or any external link.Įdges can also show statistics when you hover over the edge. Additional details can be displayed in a context menu which is displayed when you click on the node. Nodes can also show another set of values as a color circle around the node, with sections of different color represents different values that should add up to 1.įor example, you can have the percentage of errors represented by a red portion of the circle. Usually, nodes show two statistical values inside the node and two identifiers just below the node, usually name and type. You can expand hidden parts of the graph by clicking on the “Hidden nodes” markers in the graph. If this limit is crossed a warning will be visible in upper right corner, and some nodes will be hidden. Note: Node graphs can show only 1,500 nodes. ![]() ![]() The data source defines what information and values is shown, so different data sources can show different type of values or not show some values. The connection might be a request, an execution, or some other relationship between the two nodes.īoth nodes and edges can have associated metadata or statistics. An edge is displayed as a line that connects two nodes.A node might represent an application, a service, or anything else that is relevant from an application perspective. If you want to use this as a data source developer see the section about data API.Ī node graph consists of nodes and edges. This means not every data source or query can be visualized with this graph. They use a directed force layout to effectively position the nodes, so they can display complex infrastructure maps, hierarchies, or execution diagrams.Ī node graph requires a specific shape of the data to be able to display its nodes and edges. Node graphs can visualize directed graphs or networks. Grafana Cloud Enterprise Open source Node graph
