Second, the following instances of command runners need to have timeouts:
plugins/inputs/ping/ping.go
125: out, err := c.CombinedOutput()

91: if err := cmd.Run(); err != nil {
plugins/inputs/ipmi_sensor/command.go
31: err := cmd.Run()
plugins/inputs/sysstat/sysstat.go
194: out, err := cmd.CombinedOutput()
plugins/inputs/leofs/leofs.go
185: defer cmd.Wait()
plugins/inputs/sysstat/sysstat.go
282: if err := cmd.Wait(); err != nil {
