Node removal is appropriate for nodes which no longer exist, or will otherwise not be
discovered again. Nodes for which database information is no longer required, but which will
continue to be discovered, should be unmanaged rather than removed.
After removing a node, you should check any configuration pages where specific IP addresses
or hostnames might be specified (for example, Configuration > Forwarding, Configuration >
Polling, etc) and remove or modify any rules that refer to the removed node.
Configuring node groups
Node Groups represent a collection of address patterns that can be applied to IP based
configurations such as forwarding rules and proxy rules. The Configuration > Node
Management page Node Groups tab is used to create, delete, and modify Node Groups. Node
Groups may contain an arbitrary number of valid address patterns as well as other Node
Groups. When specifying a Node Group as part of a configuration or within another Node
Group, the name of the Node Group must be prefixed with '@'. For example, the Node Group
webservers would be represented in configurations as @webservers.
Note that Node Groups may not contain hostnames.
Configuring device types
During discovery, ZoneRanger uses SNMP to determine the device type of
sysObjectId
each node. The Configuration > Node Management page Device Types tab enables you to
manually assign device types to discovered nodes. If the device type of a router or switch was
manually changed to "server," its device type might change back to the actual type when
discovery is performed again.
Outbound Proxy
ZoneRanger is capable of proxying many protocols. The Configuration > Outbound Proxy
page is used to customize the configuration of various proxy services.
Configuring TCP Proxy
The Configuration > Outbound Proxy page TCP Proxy tab allows for the configuration of
the level of logging for TCP proxy services.
Figure 34-39. Configuration > Outbound Proxy page TCP Proxy tab
TCP Proxy Logging specifies the level of logging for TCP proxy requests through the
ZoneRanger. This can affect the performance of TCP proxy.
The TCP Proxy Logging levels are:
