Viewing DNS ALG Message Rate Statistics

The Oracle Communications Session Border Controller provides message rate statistics for DNS ALG traffic. You must first enable extra method statistics generation in the dns config.

To enable full DNS ALG message rate statistics:

In Superuser mode, type configure terminal and press Enter.
```
ORACLE# configure terminal
```
Type media-manager and press Enter to access the media-manager path.
```
ORACLE(configure)# media-manager
```

Type dns-config and select an existing configuration element.

ACMESYSTEM(media-manager)# dns-config
ACMESYSTEM(dns-config)# select
<realm-id>:
1: realm01
selection: 1

extra-dnsalg-stats—Set this parameter to enabled for the Oracle Communications Session Border Controller to collect message rate statistics for DNS ALG objects.
Type done when finished.
DNS ALG Message rate statistics are maintained system-wide, per realm, and per DNS Server. This command is entered as:
```
ORACLE# show dnsalg rate [realm-id <realm-name> | server-ip-addr <server-ip-address>]
```

show dnsalg rate

The show dnsalg rate command displays request and response rates for DNS messages on a system-wide basis. The rates are calculated based on the time in the current monitoring window (100+current period elapsed). The Message Received and the Messages sent columns are the sum of the corresponding Requests or responses. For example:

ORACLE# show dnsalg rate
17:31:21-15
Realm-id  Msg Recv  Msg Sent  Req Recv  Req Sent  Resp Recv  Resp Sent
              Rate      Rate      Rate      Rate       Rate       Rate
ALL            0.0       0.0       0.0       0.0        0.0        0.0

show dnsalg rate realm-id

The show dnsalg rate realm-id command displays request and response rates for DNS messages on a per-realm basis. If you add a realm-name to the query, that specific realm’s data will be returned. Entered without a realm name, all configured realms will be displayed. The rates are calculated based on the time in the current monitoring window (30+current period elapsed). The Message Received and the Messages sent columns are the sum of the corresponding Requests or responses. For example:

ORACLE# show dnsalg rate realm-id peer
17:31:31-26
Realm-id  Msg Recv  Msg Sent  Req Recv  Req Sent  Resp Recv  Resp Sent
              Rate      Rate      Rate      Rate       Rate       Rate
peer           0.0       0.0       0.0       0.0        0.0        0.0

show dnsalg rate server-ip-addr

The show dnsalg rate server-ip-addr command displays request and response rates for DNS messages on a per-DNS server basis. If you add a DNS Server IP address to the query, that specific server’s data will be returned. Entered without a server IP address, all configured servers will be displayed. The rates are calculated based on the time in the current monitoring window (30+current period elapsed). The Message Received and the Messages sent columns are the sum of the corresponding Requests or responses. For example:

ORACLE# show dnsalg rate server-ip-addr 172.16.10.5
17:32:19-44
DNS ALG Realm peer
Ip Address             Msg Recv  Msg Sent  Req Recv  Req Sent  Resp Recv  Resp Sent
                           Rate      Rate      Rate      Rate       Rate       Rate
172.16.10.5                 0.0       0.0       0.0       0.0        0.0        0.0
