Can I pull a specific system property in an API call?

You cannot pull properties from the device endpoint, but you can filter -- the method is limited (supports only one property match). You can use a filter like so (if you wish to restrict to specific values of that property).

filter=systemProperties.name:system.groups,systemProperties.value:VALUE

We’ve generally ended up with a full dump of /device/devices/$device->{id}/properties into a hash and then we reference that data as needed with a simple wrapper function to lookup property values from the hash.  It requires more API calls, but actually is useful and it works. I checked all our code and we pretty much never use that first method.

This is what I do too. Instead of filtering in the call, I just fetch everything and filter afterwards.

Sorry, one more point -- I was checking our backup script and we don’t actually use /properties there except for grouping results (/properties gives you all properties in a list, so it is appropriate if you don’t know where to look for an input property name). Within device results, there are keys to arrays for systemProperties, customProperties, autoProperties inheritedProperties. So you just have to get the device (possibly filtered by one property/value pair) and then extract what you need from those lists, like so:

sub getprop {
    my $properties = shift;
    my $name = shift;

    my $pval = (map { $_->{value} } grep { $_->{name} eq $name } @{$properties})[0];

    return $pval;
}

So for system.groups, that would be getprop($device->{systemProperties}, ‘system.groups’).

@Kelemvor ~ the script here will pull the system.groups value for you: https://github.com/krshearman/LMAPI_v3/blob/main/GetDeviceProperties_SystemGroups.py

#!/bin/env python

import requests

# - Account Info - replace with your own values
Company = ""
AccessKey = ""
AccessId = ""

# Request Info
httpVerb ='GET'
# This gets the properties for a device with id of 804
deviceId = 804
resourcePath = f'/device/devices/{deviceId}/properties'
data = ''

# Construct URL
url = 'https://'+ Company +'.logicmonitor.com/santaba/rest' + resourcePath

# Get current time in milliseconds
epoch = str(int(time.time() * 1000))

# Concatenate Request details
requestVars = httpVerb + epoch + data + resourcePath

# Construct signature
hmac1 = hmac.new(AccessKey.encode(), msg=requestVars.encode(), digestmod=hashlib.sha256).hexdigest()
signature = base64.b64encode(hmac1.encode())

# Construct headers
auth = 'LMv1 ' + AccessId + ':' + signature.decode() + ':' + epoch
headers = {'Content-Type': 'application/json', 'Authorization': auth, 'X-Version': '3'}

# Make request
response = requests.get(url, data=data, headers=headers)
strdata = response.content
parsed = json.loads(strdata)
#print(parsed)

# Print status and body of response
print('Response Status:', response.status_code)
# print('Response Body:', response.content)

for x in range(len(parsed['items'])):
    if parsed['items'][x]['name'] == "system.groups":
        print(parsed['items'][x]['value'])

Hope it helps!

I thought it might be helpful to be able to get to that property and then go from there.
