Documentation: https://github.com/greenpau/gobgp_exporter/
  • gobgp.address: Address (host and port) of the GoBGP instance we should connect to. This could be a local GoBGP server (127.0.0.0:50051, for instance), or the address of a remote GoBGP server.
  • gobgp.tls: Enable TLS for the GoBGP connection. (default: false)
  • gobgp.tls-ca: Optional path to a PEM file containing certificate authorities to verify GoBGP server certificate against. If empty, the host's root CA set is used instead. (default: empty)
  • gobgp.tls-client-cert: Optional path to a PEM file containing the client certificate to authenticate with. (default: empty)
  • gobgp.tls-client-key: Optional path to a PEM file containing the key for theclient certificate to authenticate with. (default: empty)
  • gobgp.tls-server-name: Optional server name to verify GoBGP server certificate against. If empty, verification will be using the hostname or IP used in gobgp.address. (default: empty)
  • gobgp.timeout: Timeout on gRPC requests to GoBGP.
  • gobgp.poll-interval: The minimum interval (in seconds) between collections from GoBGP server. (default: 15 seconds)
  • gobgp.peers: The file containing the mapping between router_id and the name (e.g. hostname) of a remote peer.
  • auth.token: Enable X-Token authentication for accessing the exporter itself.
  • version: Show application version.
  • web.listen-address: Address to listen on for web interface and telemetry.
  • web.telemetry-path: Path under which to expose metrics.

Expose build info for gobgp

It would be nice if gobgp exporter would expose build information of gobgp, e.g. which version it is running.

gobgp-exporter failed to init properly: context deadline exceeded source="main.go:73" - help needed

HI there,

I have followed the document to install the gobgp exporter locally. everything went well until execution of $make.
However $make qtest fails with following error..
$make qtest
INFO[0000] Starting gobgp-exporter (version=1.1.3, branch=master, revision=v1.1.3-1-g1eeeea6) source="main.go:68"
INFO[0000] Build context (go=go1.16.5, user=chimaya.dash, date=2021-07-14) source="main.go:69"
ERRO[0002] gobgp-exporter failed to init properly: context deadline exceeded source="main.go:73"

moreover when i manually run gobgp-exporter command, it works for --help, -metrics, -version flags and it fails for others flags.

Please assist. Thank you!

IPV6 compatibility for gobgp exporter

Hi,

I have noticed that GOBGP exporter is not compatible with IPV6 address. It gives parsing error when I use IPV6 address to connect to remote server.

while scanning we found, the below piece of code is throwing the error after validating the format.

arr := strings.Split(s, ":")
if len(arr) != 2 {
return fmt.Errorf("invalid address %s, expected 'ipaddress:port'", s)

Will it be possible to make it work for both IPV4 and IPV6? Please confirm.

Thank you!

Vendor packages

Would it be possible to vendor packages or provide a vendor lockfile?

Add metric for ListenAddresses

Add metric for ListenAddresses.

    if len(g.ListenAddresses) > 0 {
        fmt.Printf("Listening Port: %d, Addresses: %s\n", g.ListenPort, strings.Join(g.ListenAddresses, ", "))

Project status

Hello,

I'm considering to implement gobgp exporter but I noticed that last update was almost year ago so I'm wondering if this project is still maintained?

Thank you in advance!

Add metrics for VRF-related stuff

Currently RIB metrics only capture "default" VRF. Add an attribute to RouterNode for the holding of VRF information. Then add metrics for non-default VRF.

Using CentOS 7
go1.13.8

I haven't much experience with building Go applications so the fault might be on me. Earlier I've been getting errors regarding vendor/github.com/osrg/gobgp/api/gobgp.pb.extended.go being nonexistant, so I cloned the gobgp repository in the above directory and the build commenced, until it ran into the aforementioned issue.

runtime error: invalid memory address or nil pointer dereference

Unfortunately gobgp_exporter sometimes seems to segfault.

Using gobgp_exporter with a dns address

Hi,
seems like the validation for hostnames it's not happy with not using ip addresses.

scrubbing-engine-gobgp-exporter | ts=2023-12-22T14:29:17.620Z caller=main.go:218 level=error msg="failed to init properly" error="invalid IP address in gobgp:50051"

while trying to use the dns:// like in https://github.com/greenpau/gobgp_exporter/blob/main/pkg/gobgp_exporter/router_node.go#L96 prefix returns another error

scrubbing-engine-gobgp-exporter  | ts=2023-12-22T14:38:11.123Z caller=main.go:218 level=error msg="failed to init properly" error="address dns://gobgp:50051: too many colons in address"

Now this logic seems a bit weird to me and i want to make sure this is intended before sending out a patch especially cause the test have a lot of bad cases, for rejection but none of the good ones for ensuring that positive cases don't get rejected

https://github.com/greenpau/gobgp_exporter/blob/main/pkg/gobgp_exporter/gobgp_exporter_test.go#L35

and adding in the {address: "dns://localhost:50051", ok: true}, in the list does get it rejected.

But if i read this correctly is rejecting anything that is not an IP address

SplitHostPort tries to split in host/port but any colon before the port address will throw the too many colons error (https://cs.opensource.google/go/go/+/refs/tags/go1.21.5:src/net/ipsock.go;l=164)

so the dns:// that is saying it's valid will always throw an error, and if there's any host it will only trigger the first branch of the if/then/else statament so it's impossible for a dns name to pass.

	host, strport, err := net.SplitHostPort(s)
	if err != nil {
		return err
	} else if host != "" {
		if addr := net.ParseIP(host); addr == nil {
			return fmt.Errorf("invalid IP address in %s", s)
		}
	} else if !strings.HasPrefix(s, "dns://") {
		return fmt.Errorf("invalid address format in %s", s)
	} else {
		// "dns://" prefix for hostname is allowed per go grpc documentation
		// see https://pkg.go.dev/google.golang.org/grpc#DialContext
		idx := strings.LastIndex(s, ":")
		host = s[0:idx]
		strport = s[idx+1:]
	}

Now what was your intention for valid endpoints for gobgp? i think it make sense to give the option to give a full fledged URI and then validate, i can send the patch if that's the case and i can improve the validation method.
