Steps to reproduce:
I create a agent2 plugin. the function is to execute fping, obtain the result of fping, and execute it every 5 seconds. When my parameter IP is reachable, there is no problem with the data obtained, but when the IP is unreachable, there will be a cycle (5s) Delay
// code placeholder package icmpimport ( "encoding/json" "fmt" "regexp" "time" "zabbix.com/pkg/zbxcmd" )const Timeout = 30func FilterLossOrLatency(pingResult string) (result interface{}, err error) { re := regexp.MustCompile(`[-]?\d[\d,]*[\.]?[\d{2}]*`) resultFping := re.FindAllString(pingResult, -1) filterResult := make(map[string]string) if resultFping[len(resultFping)-1] == "100" && len(resultFping) < 6 { filterResult["lossrate"] = resultFping[4] filterResult["latency"] = "1000" } else { filterResult["lossrate"] = resultFping[4] filterResult["latency"] = resultFping[6] } return filterResult, nil }func ICMPCheck(host string) (result interface{}, err error) { c := make(map[string](chan interface{})) // for _, host := range params { // c[host] = make(chan interface{}) // go ICMPping(host, c[host]) // } c["host"] = make(chan interface{}) go ICMPping(host, c["host"]) m := make(map[string]interface{}, 0) for ind, ch := range c { m[ind] = <-ch } jsonRes, err := json.Marshal(m) if err != nil { return nil, fmt.Errorf("%s (%s)", err.Error(), "Cannot marshal JSON") } return string(jsonRes), nil }func ICMPping(host string, c chan interface{}) { s := "/usr/sbin/fping -q -b 2000 -c 5 -i 1000 " + host stdoutStderr, _ := zbxcmd.Execute(s, time.Second*time.Duration(Timeout), "") result, _ := FilterLossOrLatency(stdoutStderr) c <- result }
