NIC collector return error:"xxx label:<name:xxx> counter:<value:0>was collected before with the same name and label values"

Hello: Some of my physical servers recently returned an error when accessing a http://ipaddress:9182

An error has occurred during metrics gathering:

OS:Windows server 2008 R2 wmi_exporter version:After this problem occurred, I tried to install 0.9.0 and 0.11.1 on these servers,but nothing improved. ENABLED_COLLECTORS="cpu,cs,logical_disk,logon,memory,net,os,service,system,tcp,textfile"

Is there any way to solve this problem? Thanks!

Hi @david1024wu, Looks like you have multiple interfaces with the same name, or names that end up the same after the sanitizing pass we do (replacing everything that isn't a-z or 0-9 with _). If you check in perfmon, what instances do you have of the Network Interface counters?

[david1024wu]

Hi carlpett,Thank you for your comment. I checked the perfmon,the instances of the network interface counters don't seem to have the same name.

But in cmd run:wmic nic list brief,There are NICs and they have the same name.

I have the same problem. My physical server is an HP Proliant ML350pGen8.

There are 4 NICs. Under "Control Panel", "Network and Internet", "Network Connections", they are:  Name: "Ethernet", "Ethernet 2", "Ethernet 3", "Ethernet 4".  Device Name: all 4 are "HP Ethernet 1Gb 4-port 331i Adapter" I can rename them, but only the "Ethernet X" name, not the "Device Name".

Command "wmic nic list brief" lists (among other NICs):

AdapterType DeviceID MACAddress Name ServiceName Ethernet 802.3 10 xx:xx:xx:xx:xx:DA HP Ethernet 1Gb 4-port 331i Adapter q57nd60a Ethernet 802.3 11 (redacted out):D9 HP Ethernet 1Gb 4-port 331i Adapter q57nd60a Ethernet 802.3 12 (redacted out):D8 HP Ethernet 1Gb 4-port 331i Adapter q57nd60a Ethernet 802.3 13 (redacted out):DB HP Ethernet 1Gb 4-port 331i Adapter q57nd60a

All Windows Exporter errors are like this one:

collected metric "windows_net_bytes_received_total" { label:<name:"nic" value:"HP_Ethernet_1Gb_4_port_331i_Adapter" > counter:<value:1.80533694e+08 > } was collected before with the same name and label values

I am no Windows expert, but is that "Name" or "Device Name" required to be unique? Shouldn't the Windows Exporter be using the "DeviceID"?

[rdiez]

As a workaround, I tried blacklisting the common NIC name, but this had no effect:

msiexec /passive /i windows_exporter-0.16.0-amd64.msi EXTRA_FLAGS="--collector.net.nic-blacklist HP_Ethernet_1Gb_4_port_331i_Adapter"

So I had to disable the entire 'net' collector like this:

msiexec /passive /i windows_exporter-0.16.0-amd64.msi ENABLED_COLLECTORS=cpu,cs,logical_disk,os,service,system,textfile

I could not find a way to disable a single collector, so I manually added those documented as "Enabled by default", except for 'net'.

Same problem here, 2 virtual interfaces with same name, collector not working

[breed808]

The Perflib source used by the collector doesn't expose a device ID. We could add a second source (WMI for example) and enable it with a collector flag.

Happy to review any PRs for this!
