Does not generate data

[cardosocristian]

I have a Centos 7 server, with Openvpn in version 2.4.9, golang in version 1.15.1 and after following this tutorial
"https://kifarunix.com/monitor-openvpn-connections-with-prometheus-and-grafana/" which refers to your exporter was not successful.
You are generating the following error when running:
xporter
2021/03/03 16:09:01 Listen address: 10.10.10.10:9176
2021/03/03 16:09:01 Metrics path: / metrics
2021/03/03 16:09:01 openvpn.status_path: /etc/openvpn/openvpn-status.log
2021/03/03 16:09:01 Ignore Individuals: false

2021/03/03 16:09:09 Failed to scrape showq socket: unexpected file contents: "OpenVPN CLIENT LIS"
2021/03/03 16:09:24 Failed to scrape showq socket: unexpected file contents: "OpenVPN CLIENT LIS"

The above error occurs, every time I open / metrics, it follows main.go's config

func main () {
var (
listenAddress = flag.String ("web.listen-address", "10.10.10.10:9176", "Address to listen on for web interface and telemetry.")
metricsPath = flag.String ("web.telemetry-path", "/ metrics", "Path under which to expose metrics.")
// openvpnStatusPaths = flag.String ("openvpn.status_paths", "examples / client.status, examples / server2.status, examples / server3.status", "Paths at which OpenVPN places its status files.")
openvpnStatusPaths = flag.String ("openvpn.status_paths", "/etc/openvpn/openvpn-status.log", "Paths at which OpenVPN places its status files.")
ignoreIndividuals = flag.Bool ("ignore.individuals", false, "If ignoring metrics for individuals")
)
flag.Parse ()

Could you help me please?

Just change/add the status version like into config file:

status-version 2

Exporter support only 2 or 3 versions.

Thanks for the help, I modified the service and managed to capture a large part of the logs.

Some logs are not being populated, such as:

openvpn_server_connected_clients {status_path = "/ etc / openvpn / openvpn-status.log"} 0

It was not very clear to me if the values below should appear in / metrics or is generated to export only
openvpn_server_client_received_bytes_total
openvpn_server_client_sent_bytes_total

#Configuration line
openvpn --status /etc/openvpn/openvpn-status.log --status-version 3 --suppress-timestamps --cd / etc / openvpn / --config server.conf

I configured the service with status-version 2 and then 3 to test it, but it didn't work to generate the data above.

The version of Openvpn I am using is "OpenVPN 2.4.9 x86_64-redhat-linux-gnu"

I apologize if something went wrong, but as I am only a system administrator, I am still starting to use this type of service to export data.
Once again, thank you very much for your help and attention.
