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.
Use the show-statistics subcommand to view load distribution details. The following example shows the usage of the show-statistics subcommand:
ilbadm show-statistics 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
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 23-7 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.
Use the show-persist subcommand to view the session persistence mapping table.
Example 23-8 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.
