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:
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
