I have a working beat created using Beats framework. However i am not able to execute bash commands from inside using exec.Command().
Build process of this beat is same that is listed on beats framework.
[root@10.142.41.140 nvidiagpubeat]$ make
go build -i -ldflags "-X github.com/elastic/beats/libbeat/version.buildTime=2019-02-06T21:48:53Z -X github.com/elastic/beats/libbeat/version.commit=0e2fe4d23b6393ab6782e7eb703715bc3d56112d"
[root@10.142.41.140 nvidiagpubeat]$ ./nvidiagpubeat -c nvidiagpubeat.yml -e -d "*"
func command() {
gpucount := "ls /dev | grep nvidia | grep -v nvidia-uvm | grep -v nvidiactl | wc -l"
cmd := exec.Command("bash", "-c", gpucount)
out, err := cmd.Output()
if err == nil {
fmt.Println(string(out))
}
}
//Run Contains the main application loop that captures data and sends it to the defined output using the publisher
func (bt *Nvidiagpubeat) Run(b *beat.Beat) error {
command()
...
}
This throws an error
2019-02-06T14:52:31.261-0700 ERROR beater/nbeat.go:65 ********** Unable to run command , error: fork/exec /usr/bin/bash: operation not permitted
I can run the same code in a simple test.go file and run it but not from beat.
