Microsoft.LS.2015.Monitoring.Rule.ReportingPC.AccessEdge.PERF_NET_S_AVERAGE_DNS_QUERY_TIME (Rule)

Knowledge Base article:

Summary

This rule collects this performance counter for reporting/troubleshooting purposes for the counter: PERF_NET_S_AVERAGE_DNS_QUERY_TIME

The average time (in seconds) it takes to perform a DNS query.

Causes

DNS queries are taking too long to complete.

Resolutions

This might be a temporary condition. If the problem persists, check that queries are being routed to the expected DNS server and that the DNS server is not overloaded. Also check that the DNS cache size is set appropriately in CMS for the number of SIP message domains that the Access Edge Server processes.
