Topology interface elements
Network Topology visualizes your Google Cloud network as a graph . You can use the graph to explore your existing configurations and quickly troubleshoot networking issues. To view a Network Topology graph, see Monitor your networking configuration with Network Topology .
The Network Topology graph includes the following elements.
In the Infrastructure view, a drop-down menu to filter by traffic type:
- Cross-zonal : Displays a ranked table of outliers with the traffic between Google Cloud zones, and excludes the traffic between entities within the same zone.
- To the internet : Displays a ranked table of outliers with the traffic from Google Cloud to external endpoints, excluding hybrid traffic.
- Hybrid : Displays a ranked table of outliers with the traffic through Cloud VPN, Cloud Interconnect, and router appliances.
- All measured egress : Displays a ranked table of outliers with the traffic from an entity.
In the GKE view, a drop-down menu to filter by traffic type:
- Cross-zonal: Displays a ranked table of outliers with the traffic between Google Cloud zones, and excludes the traffic between entities within the same zone.
- All measured egress: Displays a ranked table of outliers with the traffic from an entity.
Select the checkbox to display only the traffic paths between top-level entities, such as regions.
To view the traffic paths between lower-level entities, select or hold the pointer over the entities. To display all the traffic paths, clear the checkbox.
Use entity-type:entity_name or just entity_name values that specify the entities that you want to find in the topology along with their communication peers. Filters for entity names can contain asterisks.
Filters
can help you quickly highlight and focus on specific entities,
especially when you need to quickly diagnose and troubleshoot issues. For
example, you can specify a region filter that shows the us-east4
region and all entities that are communicating with its resources.
You can also use the asterisk ( *
) to create advanced patterns and search for
entities. For example, you can use the value *replica*
to
search for all entities containing replica
in their name. You can put
asterisks anywhere within the pattern, matching arbitrary sequences of
characters in entity names.
To view information about one or more entities, hold the pointer over or click the entities.
- To expand or collapse an entity , hold the pointer over it and click its icon to move between different hierarchies of an entity. For more information about expanding and collapsing entities, see Navigate entity hierarchies .
- To view your selected metric for all traffic paths to an entity , hold the pointer over the entity. All entities that have a connection to this entity remain active, but all other entities are blurred. In the top-right corner of the screen, a card appears to list the name, type, and hierarchy of the entity.
- To continue viewing the traffic paths of the entity , left-click the entity. This action selects the entity and puts a ring around its icon.
- To select more entities
and view their traffic paths, hold down
the key that you use to select multiple files on your workstation (usually
controlorshift) and left-click each additional entity. - To remove an entity from the group of selected entities
, hold down the
controlkey on your keyboard and left-click the selected entity. - To discard the selected group of entities and select
the current entity
, click an entity without using the
controlkey.
Shows the full range of data that Network Topology has collected.
The timeline is broken into hourly segments that you can select by using the slider. When you select a different time segment, the graph reloads. You can also select the current hour with incomplete data.
