Is it possible to export list of devices in csv or similar

Help
1

Hey guys,

Short question:
Is there an easy way to export a list of devices including ip,hostname,os as a csv or list from librenms?

2

I’m not sure about the webui, but you could always do select ip,hostname,os from devices or use the API.

I went the api->powershell way, thanks for your suggestions

Nice, you should post your command here for others :slight_smile:

well a very short example is this:

        # define the url/adress of your librenms server ( leave /api/v0/ intact)
        $baseurl = "http://librenms.lol/api/v0/"

        #fill in api token which you can retrieve from  web interface
        $token = "your api token"

    # generating header(do not touch)
        $header = @{
        "X-Auth-Token" = $token}

    #defining url to get devices
        $gdevices = $baseurl + "devices?type=network"

    #invoking api request and showing results in grid view
        Invoke-RestMethod -uri $gdevices -Headers $header |select  -ExpandProperty devices -ExcludeProperty sysDescr |ogv

As Aauvinet found out below: the invoke-restmethod command is not available in powershell 2 or below. please installl windows Management framework 5 (which includes a newer version of powershell) or above to work around this .

@telskamp,

I try you scrip in poweshell… but i don’t work to me

I do :
I open powershell
I put in cli

$baseurl = "http://librenms.my/api/v0/"

$token = “removed”
$header = @{
“X-Auth-Token” = $token}
$gdevices = $baseurl + "devices?type=network"
Invoke-RestMethod -uri $gdevices -Headers $header |select -ExpandProperty devices -ExcludeProperty sysDescr |ogv

But Invoke-RestMethod isn’t know by powershell

did you change the url to reflect your url?

Invoke-RestMethod has been added in powershell v3.0 you are probably trying to execute the command on a windows 7 or server 2008 machine. please try on newer windows version or install windows management framework 5 or later

if you want to see the powershell version of your machine please type $psversiontable in your powershell window

Hello,
Unburying this thread, I try to obtain a list of all my network devices.
So far, it seems that ?type=network does not work anymore.

My request is:

curl -H 'X-Auth-Token: MyFavoriteAPIToken' 'http://localhost/api/v0/devices/?type=network'

This returns a list of all equipments, firewalls, servers etc, not limited to network.
Having read the documentation at https://docs.librenms.org/API/Devices/#get_device, I can’t find the answer.

So far, I have mostly HP switches so I workaround the issue by doing :

curl -H 'X-Auth-Token: MyFavoriteAPIToken' 'http://localhost/api/v0/devices/?type=os&query=procurve'

Is there a ‘good’ way to get only network devices from an API query ?

Best regards.

I created a Python-script to recursively crawl all network devices for relevant information. In my case I specifically wanted all serial numbers of all devices (and parts) in LibreNMS.
