COREDNS-PPROF(7) CoreDNS Plugins COREDNS-PPROF(7) NAME pprof - publishes runtime profiling data at endpoints under /de- bug/pprof. DESCRIPTION You can visit /debug/pprof on your site for an index of the available endpoints. By default it will listen on localhost:6053. This is a debugging tool. Certain requests (such as collecting execu- tion traces) can be slow. If you use pprof on a live server, consider restricting access or enabling it only temporarily. This plugin can only be used once per Server Block. SYNTAX pprof [ADDRESS] Optionally pprof takes an address; the default is localhost:6053. An extra option can be set with this extended syntax: pprof [ADDRESS] { block [RATE] } • block option enables block profiling, RATE defaults to 1. RATE must be a positive value. See Diagnostics, chapter profiling <https://golang.org/doc/diagnostics.html> and runtime.SetBlockPro- fileRate <https://golang.org/pkg/runtime/#SetBlockProfileRate> for what block profiling entails. EXAMPLES Enable a pprof endpoint: . { pprof } And use the pprof tool to get statistics: go tool pprof http://local- host:6053. Listen on an alternate address: . { pprof 10.9.8.7:6060 } Listen on an all addresses on port 6060, and enable block profiling . { pprof :6060 { block } } SEE ALSO See Go's pprof documentation <https://golang.org/pkg/net/http/pprof/> and Profiling Go Programs <https://blog.golang.org/profiling-go-pro- grams>. See runtime.SetBlockProfileRate <https://golang.org/pkg/runtime/#Set- BlockProfileRate> for background on block profiling. CoreDNS March 2021 COREDNS-PPROF(7)
