# go-pg-slowlog
A Go library for parsing and collecting the slowlog of PostgreSQL.
## Usage
```go
package main
import (
"fmt"
"log"
"os"
"github.com/tkuchiki/go-pg-slowlog/parser"
)
func main() {
f, err := os.Open("/path/to/postgresql-xxx.log")
if err != nil {
log.Fatal(err)
}
defer f.Close()
logLinePrefix := "%m [%p]"
slowLogParser, err := parser.NewPGSlowLogParser(f, logLinePrefix)
if err != nil {
log.Fatal(err)
}
defer slowLogParser.Stop()
go slowLogParser.Start()
for logEntry := range slowLogParser.LogEntryChan() {
fmt.Println(logEntry.Duration, logEntry.Statement)
}
// example output
// 1.009444s SELECT * FROM singers
// 1.002257s SELECT * FROM albums
}
