Hi

We have some HP DL360 servers that are detected in LibreNMS with OS of Windows Server.
However the ‘Hardware’ section shows: Intel x64.
When running a ./discovery.php against the host I get the following (snapshot of relevant items hopefully:

Modules status: Global+

An example processor from the list:-

Can anyone suggest how to resolve the discovery of these servers hardware types?

Thanks in advance.

Run the commands outlined here https://docs.librenms.org/Support/FAQ/#faq20

HI @Jellyfrog

I’ve completed the discovery and got this, has it worked?

./discovery.php !hostnameremoved! 2021-02-18 10:21:58 - 1 devices discovered in 1575. secs
title:
name: xxxx
private: 1
expire: 0
curl: (6) Could not resolve host: 'https

./poller.php !hostnameremoved! 2021-02-18 10:24:55 - 1 devices polled in 4.392 secs
title:
name: xxxx
private: 1
expire: 0
curl: (6) Could not resolve host: 'https

Any ideas?

Kind regards

#4

It looks like you have entered URLs instead of hostnames?

#5

HI @Jellyfrog

it does appear that way, but I manually typed in the FQDNs of the device as it appears in LibreNMS.

Kind regards

#6

Okey maybe you have one of those weird systems without https support in curl.

Try these and replace HOSTNAME with the ip of the machine

./discovery.php -h HOSTNAME -d
./poller.php -h HOSTNAME -r -f -d
snmpbulkwalk -OUneb -v2c -c COMMUNITY HOSTNAME .

Hi @Jellyfrog

Thanks for the response.
The commands you supplied work if you use the hostname or or IP.
I think you are right, there appears to be something in the curl command using the " | ./pbin.sh" of the command.

Any ideas on the curl component to install/update to fix this?

Kind regards

#8

The problem with pbin.sh has been fixed in nightly

#9

Thanks @Jellyfrog

I’ve run this again and uploaded what I can.

Err seems youre a bit unlucky, that error is from our pastebin…
Anyway, Windows support is quite limited, what youre seeing is set here; https://github.com/librenms/librenms/blob/master/LibreNMS/OS/Windows.php#L59

If you want to contribute better support for windows, im all for it.

#11

Hey @Jellyfrog
It’s feeling that way :upside_down_face: :upside_down_face:

The interesting thing is that this only seems to affect HP servers running Windows, Dell devices capture their device info properly as below:

Dell Hardware:

HP Hardware:

Is there just an issue with the vendor hardware MIB support or the way it’s being read?

I can’t see anything windows OS support link you included that references either vendor so believe that this isn’t an OS issue.

However happy to add and dev the Windows functionality, huge opportunity there and as I understand, a deadline on SNMP support for Windows until this will become a limiting factor for the solution.
Are you focusing on Check_MK or NSClient++ for WIndows integration?

Kind regards

#12

I missed this, https://github.com/librenms/librenms/blob/master/LibreNMS/OS/Traits/ServerHardware.php#L57

so thats what it tries to read, you should snmpwalk and check if you need to add something, probably some “hp health snmp agent” or something you need to install

#13

Cheers @Jellyfrog

I’ve just run an SNMP discovery again and I believe it’s related to the exposure of system information through iLO on an HP device, for some reason the system information does return through a standard SNMP test.
Allowing passthrough SNMP from the iLO also doesn’t pass the necessary information through.

It’d be interesting to see if anyone else on the forum has found similar and a workaround.

Kind regards
