An arrow represents the connection between the objects on the map and/or the clients as well. When looking at the Tier view, it will list the number of connections between Tiers. You can click on the connection line to see a list of the connections and details about it.
When you expand the tier, you can see the individual connections and the protocol by hovering over the server (e.g. 1433 ms-sql). When looking at the connection properties or the Legacy view, you will see the port number as well.
When you see an arrow displayed for each port and each direction. The colour of the arrow indicates how recent the latest activity was, and you can refer to the Connection Color Legend. You can also see this key on the maps by clicking at the bottom and expanding the key.
If you have sensors deployed in VMware, you may be able to see the schema name of a database that is being connected to.
Note: The connection failure threshold is configurable via Settings > Global Parameters >Connection failures sensitivity field.
The protocol names are presented according to the IANA Service Name and Transport Protocol Port Number Registry.
Tier-Based Connections
You can left-click a connection line to open the Connection Properties window. This shows basic info about the connection and lets you access options like Charts, Remove from Baseline, and Filter Out. You can drill down into each connection to get more detailed info.
Charts β View traffic and connection failure trends over time. If there are multiple connections, select one to see its chart. See our Charts guide for more details.
Remove from Baseline β Excludes the connection from the baseline so it appears as new. In the Tier-based view, this applies to all related connections.
Filter Out β Hides the connection from the map. In the Tier-based view, this applies to all related connections.
You can also right-click a connection and choose Pin Connection to keep it visible on the map.
Legacy Map Properties
When looking at the Legacy map, you can see details on the individual connections and have the same options as above. In addition, you can perform the following actions -
Filter connection: Creates a filter on this connection so that it is removed from the map
Filter out port: Creates a filter to exclude all traffic on the port that this connection is using from the map
Remove from Baseline - This will remove a connection from the baseline, so it will appear as a new connection on the current view.
See our Filters guide for detailed information on creating connection filters on the maps.
