Logpresso Graph

Knowledge Graph

The management screen for browsing and editing graph nodes and edges directly. It has three tabs: Nodes, Edges, and Graph.

Nodes Tab

• Type filter: a searchable dropdown for selecting multiple node types. Type names are localized and also match their English codes.
• Keyword search: partial match on value or display name.
• Click a row to open the node detail panel on the right; check multiple rows to delete them. Deleting a node also removes its attributes and connected edges.

Adding a Node

Press Add Node and pick a type — the value field's placeholder then shows the format that type expects. For example, a network-service node expects 10.0.1.5:443/tcp, and a cve node expects CVE-2024-1234.

For types with a declared format, a mismatching value shows an error and disables the Add button. The value is the node's identifier and cannot be changed after creation.

Node Detail Panel

Opens when you click a node; it has three sub-tabs.

• Graph — visualizes the node's neighborhood. Double-click a node or use the Expand menu to unfold more neighbors.
• Properties — edit the display name, risk score, tags, and type-specific attributes. Attributes defined in the schema show their names and input hints; custom attributes can be added as well. Press Save to apply.
• Edges — manage this node's connections (below).

Adding a Connection

Press "Add Connection" in the Edges tab and proceed as follows.

1. Choose the direction — outbound (this node → target) or inbound (target → this node).
2. Connectable node types are listed as boxes. Each box is a target type, and the chips inside it are the relationships defined between that type and this node. Only schema-defined connections can be created. For example, an ipv4-addr node's outbound direction shows boxes such as Zone (belongs-to), CVE (has-vulnerability), and Employee (assigned-to).
3. Click a relationship chip — the target search is then restricted to that type. Existing nodes are listed even before you type anything, so you can pick while seeing what exists.
4. Select the target node and press Add.

The connection list shows the direction arrow, relationship name, and target node; remove one with the ✕ button.

Edges Tab (All Edges)

Browse all edges with a relationship-type filter and keyword search. Click a row to edit edge attributes (for example, the remediation status of has-vulnerability, or the confidence of attributed-to).

Graph Tab

Search for a node in the top search box to place it on the canvas, then double-click to expand neighbors and explore relationships visually. Clicking a node opens its property panel.
