Measures reported by CtxNsRnatIpTest
With ‘Reverse Network Address Translation’ (RNAT), the NetScaler replaces the source IP addresses in the packets generated by hosts in the configured subnet with the configured, NAT IP address(es). Typically, RNAT is used to allow servers configured with private non-routable IP addresses to initiate connections to the Internet.
In the event of an overload, the CtxNsRnatTest test will enable you to determine whether/not the RNAT sessions are imposing excessive load on the NetScaler appliance. If so, then, you can use the CtxNsRnatIpTest test to isolate the client IP address that is generating maximum load.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Current_sessions |
Indicates the number of current RNAT active sessions originating from this client IP address. |
Number |
This is a good indicator of the RNAT session load generated by a client IP address on the NetScaler appliance. Compare the value of this measure across IP addresses to identify the client that is generating the maximum session load. |
| Req_for_cons_sent |
Indicates the number of requests for connections that were sent during the RNAT sessions that originated from this client IP address since the last measurement period. |
Number |
|
| Data_received |
Indicates the number of bytes that were received during RNAT sessions that originated from this client IP address since the last measurement period. |
MB |
These measures are good indicators of the load imposed by RNAT sessions started by a client IP address on the NetScaler appliance. By comparing the value of these measures across IP addresses, you can quickly and accurately isolate the IP address that is responsible for the maximum data load. |
| Data_transmitted |
Indicates the number of bytes that were transmitted during RNAT sessions that originated from this client IP address since the last measurement period. |
MB |
| Packets_received |
Indicates the number of packets that were received during RNAT sessions that originated from this client IP address since the last measurement period. |
Number |
These measures are good indicators of the load imposed by RNAT sessions started by a client IP address on the NetScaler appliance. By comparing the value of these measures across IP addresses, you can quickly and accurately isolate the IP address that is responsible for the maximum packet load. |
| Packets_transmitted |
Indicates the number of packets that were sent during RNAT sessions that originated from this client IP address since the last measurement period. |
