Trying to list all Feature Services in Portal and what Maps use those specific services

[phess_luckstone]

So I am trying to create an excel document that list all of my feature services / feature collections  and what specific maps they are in, so far I have this, but when it runs it lists all my services in Column A, but then Column B is blank, any idea what could be happening?  I am very new to python.  Any help would be appreciated.

import arcgis
import openpyxl

# Set the URL of your ArcGIS Online portal
portal_url = 'https://yourportal.arcgis.com'

# Set your ArcGIS Online username and password
username = 'your_username'
password = 'your_password'

# Connect to the portal
gis = arcgis.GIS(portal_url, username, password)

# Search for all feature services and feature collections in the portal
items = gis.content.search(query='type: "Feature Service" OR type: "Feature Collection"', max_items=5000)

# Create a new Excel workbook
workbook = openpyxl.Workbook()
worksheet = workbook.active

# Add a header row to the worksheet
worksheet.append(['Feature Service/Collection', 'Maps Using Feature'])

# Iterate through the feature services and feature collections
for item in items:
    # Search for maps in the portal that use the feature service or feature collection as a layer
    maps = gis.content.search(query=f'type: "Web Map*" AND layers: {item.id}', max_items=5000)
    
    # Create a list of the map names
    map_names = [map.title for map in maps]
    
    # Add a row to the worksheet with the feature service/collection name and the list of map names
    worksheet.append([item.title, *map_names])

# Save the workbook to a file
workbook.save('feature_services_maps.xlsx')

When I tested this, I was getting an empty empty list when I printed the map_names list.  Are you sure it is populating?  I would try building in some print statements to test your results.

This is what the output looks like for me, I am using Enterprise 10.8.1, it seems like it is picking up more than just services but the built in esri tools as well.

your map_names variable is trying to populate a list with map.title, and it errors out telling me that map has no attribute 'title'

As I think it's more reliable that way.

 I'm also not 100% sure you can query a webmap on its layers using the gis.content.search function. I wrote some code to search webmaps for all services in a portal/agol instance to find services that were unused, which you can find here https://github.com/joshsharpheward/gis-administration/blob/master/find_unused_services.py which I think you could modify to do what you need or at least use for inspiration!

So modifying a little of what you your code is, I was able to get the output of every map and every service inside of the map using this:

from arcgis.gis import GIS
from arcgis.mapping import WebMap
import arcpy
import pandas as pd

def main():
    # logs into active portal in ArcGIS Pro
    gis = GIS('pro')

    arcpy.AddMessage("Logged into {} as {}".format(arcpy.GetActivePortalURL(), gis.properties['user']['username']))

    # creates list of items of all map image, feature, vector tile and image services (up to 10000 of each) in active portal
    services = (gis.content.search(query="", item_type="Map Service", max_items=10000) +
                gis.content.search(query="", item_type="Feature Service", max_items=10000) +
                gis.content.search(query="", item_type="Vector Tile Service", max_items=10000) +
                gis.content.search(query="", item_type="Image Service", max_items=10000))

    arcpy.AddMessage('Searching webmaps in {}'.format(arcpy.GetActivePortalURL()))

    # creates list of items of all webmaps in active portal
    web_maps = gis.content.search(query="", item_type="Web Map", max_items = 10000)

    # Create an empty data frame to store the data
    df = pd.DataFrame(columns=['Web Map', 'Service URL'])

    # loops through list of webmap items
    for item in web_maps:
        # creates a WebMap object from input webmap item
        web_map = WebMap(item)
        # accesses basemap layer(s) in WebMap object
        basemaps = web_map.basemap['baseMapLayers']
        # accesses layers in WebMap object
        layers = web_map.layers

        # loops through basemap layers
        for bm in basemaps:
            # tests whether the bm layer has a styleUrl(VTS) or url (everything else)
            if 'styleUrl'in bm.keys():
                for service in services:
                    if service.url in bm['styleUrl']:
                        services.remove(service)
            elif 'url' in bm.keys():
                for service in services:
                    if service.url in bm['url']:
                        services.remove(service)

        # loops through layers
        for layer in layers:
            # Add a new row to the data frame for each service used in the web map
            if hasattr(layer, 'styleUrl'):
                df.loc[len(df)] = [item.title, layer.styleUrl]
            elif hasattr(layer, 'url'):
                df.loc[len(df)] = [item.title, layer.url]

    # Save the data frame to an Excel file
    df.to_excel('web_maps.xlsx', index=False)

if __name__ == "__main__":
    main()
