Displaying DNS cache proxy statistics

The GSLB ServerIron ADX maintains statistics for the transparent DNS as well as DNS proxy mode query intercept and DNS cache proxy features.

The following statistics are displayed for DNS cache proxy:

•Number of DNS queries the GSLB ServerIron ADX has responded to using the DNS cache proxy feature instead of forwarding the queries to the DNS server. (See the Direct response field under “DNS cache proxy stat:” in the output.)

The following statistics are displayed for transparent DNS query intercept:

•Number of queries the ServerIron ADX has redirected to a proxy DNS server or another ServerIron ADX. (See the Redirect field under “DNS query intercept stat:” in the output.)

•Number of queries to which the ServerIron ADX has directly responded using a transparent DNS query intercept IP address configured on the ServerIron ADX itself. (See the Direct response field under “DNS query intercept stat:” in the output.)

NOTE

The counter displayed from the show gslb global-statcommand are maintained differently on the Management and BP consoles. On the Management console the counts are aggregated from all BPs. On the BP console the count displayed os only for the BP being accessed.

To display DNS cache proxy statistics, enter the following command at any level of the CLI.

ServerIronADX(config)# show gslb global-stat
