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-stat command 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
