Displaying ILB Statistics

You can use the ilbadm command to obtain information such as printing statistics of a server or a rule, or displaying NAT table information and session persistence mapping table. For a list of definitions, see the ILB Terminology.

Obtaining Statistical Information Using the show-statistics Subcommand

Use the show-statistics subcommand to view load distribution details. The following example shows the usage of the show-statistics subcommand:

ilbadm show-statics
 PKT_P   BYTES_P   PKT_U   BYTES_U   PKT_D   BYTES_D
  9       636        0        0        0        0

where

• PKT_P: Packets processed

• BYTES_P: Bytes processed

• PKT_U: Unprocessed packets

• BYTES_U: Unprocessed bytes

Displaying the NAT Connection Table

Use the show-nat subcommand to view the NAT connection table. No assumptions should be made about the relative positions of elements in consecutive runs of this command. For example, executing {{ ilbadm show-nat 10}} twice is not guaranteed to show the same 10 items twice, especially on a busy system. If a count value is not specified, the entire NAT connection table is displayed.

The following example displays five entries from the NAT connection table:

Example 27-7 NAT Connection Table Entries ilbadm show-nat 5

 UDP: 124.106.235.150.53688 > 85.0.0.1.1024 >>> 82.0.0.39.4127 > 82.0.0.56.1024
UDP: 71.159.95.31.61528 > 85.0.0.1.1024 >>> 82.0.0.39.4146 > 82.0.0.55.1024
UDP: 9.213.106.54.19787 > 85.0.0.1.1024 >>> 82.0.0.40.4114 > 82.0.0.55.1024
UDP: 118.148.25.17.26676 > 85.0.0.1.1024 >>> 82.0.0.40.4112 > 82.0.0.56.1024
UDP: 69.219.132.153.56132 > 85.0.0.1.1024 >>> 82.0.0.39.4134 > 82.0.0.55.1024

The format of entries is as follows:

 T: IP1 > IP2 >>> IP3 > IP4

T: The transport protocol used in this entry.
IP1: The client's IP address and port.
IP2: The VIP and port.
IP3: If half-NAT mode, the client's IP address and port.
If full-NAT mode, the client's IP address and port.
IP4: The back-end server's IP address and port.

Displaying the Session Persistence Mapping Table

Use the show-persist subcommand to view the session persistence mapping table.

Example 27-8 ilbadm show-persist 5

The following example displays five entries from the table:

rule2: 124.106.235.150 --> 82.0.0.56
rule3: 71.159.95.31 --> 82.0.0.55
rule3: 9.213.106.54 --> 82.0.0.55
rule1: 118.148.25.17 --> 82.0.0.56
rule2: 69.219.132.153 --> 82.0.0.55

The format of entries is as follows:

 R: IP1 --> IP2

R: The rule that this persistence entry is tied to.
IP1: The client's IP address.
IP2: The back-end server's IP address.
