This is adding a parameter to the core `dns_slow_query_ms` Example: ``` dns_slow_query_ms=100 ``` When using the internal resolver any query taking more than `dns_slow_query_ms` will be lodged as a warning : ``` dns_slow_query_ms=10 (example with 10ms) 5(5960) WARNING: <core> [core/resolve.c:752]: get_record(): res_search[35][us-west-wa.sip.flowroute.com]elapsed[12ms] 5(5960) WARNING: <core> [core/resolve.c:752]: get_record(): res_search[1][ep-us-west-wa-01.flowroute.com]elapsed[12ms] ``` and a statistic counter will be incremented : ``` kamcmd stats.fetch dns:slow_dns_request { dns.slow_dns_request: 1 } ``` I think this will be a good start to monitor the impact of slow DNS queries on Kamailio.
