开源软件名称:google/gops开源软件地址:https://github.com/google/gops开源编程语言:Go 100.0%开源软件介绍:gopsgops is a command to list and diagnose Go processes currently running on your system. $ gops
983 980 uplink-soecks go1.9 /usr/local/bin/uplink-soecks
52697 52695 gops go1.10 /Users/jbd/bin/gops
4132 4130 foops * go1.9 /Users/jbd/bin/foops
51130 51128 gocode go1.9.2 /Users/jbd/bin/gocode InstallationTo install the latest version of gops: $ go get github.com/google/gops or $ go install github.com/google/gops@latest To install a specific gops version, for example v0.3.19: $ go install github.com/google/[email protected] DiagnosticsFor processes that start the diagnostics agent, gops can report additional information such as the current stack trace, Go version, memory stats, etc. In order to start the diagnostics agent, see the hello example. package main
import (
"log"
"time"
"github.com/google/gops/agent"
)
func main() {
if err := agent.Listen(agent.Options{}); err != nil {
log.Fatal(err)
}
time.Sleep(time.Hour)
} Otherwise, you could set ManualIt is possible to use gops tool both in local and remote mode. Local mode requires that you start the target binary as the same user that runs gops binary. To use gops in a remote mode you need to know target's agent address. In Local mode use process's PID as a target; in Remote mode target is a Listing all processes running locallyTo print all go processes, run $ gops
