Listing Feature Classes Used By ArcGIS Server Services

RogerDunnGIS

Arriving at a new organization, I wasn't sure how our geodatabase feature classes and tables were used in ArcGIS Server. If I want to shut down services locking down a feature class, which services should I shut down? If I am replacing a feature class with a new one, which map documents and Pro projects should I modify and republish? The script I created has served me, and I wanted to share it with you, after obfuscating our connection details.

As I am not allowed to attach .ipynp files to a post, there will be some copying and pasting involved. I will describe exactly what you have to do to list out all of your services' dependencies. You can then search the CSV output for the feature classes and tables you're wondering about, and see which services use them.

Open Start > ArcGIS > Jupyter Notebook
Browse to a folder where you would like to store a script about passwords, then click New > Python 3. You'll have to change the name later. Until then, it will be named Untitled.ipynp
Copy and paste the following code into the cell:

import keyring
keyring.set_password("ArcGIS Portal", "admin", "password")

Change "admin" to the username of your ArcGIS Server/Portal administrator
Change "password" to the password of that account
Run the cell by pressing Ctrl+Enter. There will be no output and that's okay
Close the browser tab representing the file
In the Jupyter window listing your folders and files, check the box next to Untitled.ipynb (its icon will be a green book because it is running)
Click the orange Shutdown button at the top of the list
Check the box next to Untitled.ipynb again
Click the Rename button at the top of the list
Rename your file. This file should be safeguarded by you. You should NOT publish this file to a blog, code-sharing web site, or put it on a file server where lay users of your organization can find it, as it is pure text and contains a powerful password. But you need to perform this step to run the code that will follow
Once again in Jupyter, browser to a folder where you want the next script and click New > Python 3
Copy and paste the code at the bottom of this post into the cell. Feel absolutely free to split the code into logical blocks. With your cursor at a desired spot in the code block, hit Ctrl+Shift+Minus. This will allow you run blocks of code, one at a time, as you debug the code for your needs
Read through the code, replacing text constants as needed. For instance, replace variables like the adminURL with the actual URL to your ArcGIS Server Administrator Directory and tokenURL with the actual URL of your token generator. [Finding these URLs is outside the scope of this post and can be found in the product documentation]
With code divided into chunks as you please, run a cell using keyboard shortcuts like Ctrl+Enter (to run and keep the cell selected), Shift+Enter (to run the cell and select the next one down), or Alt+Enter (to run the cell and insert a new cell below). Feel free to add print() statements to show the output of various commands
Scripts are meant to be modified. If a CSV output isn't what you want, modify the script to suit your needs! Perhaps you want to pump the output to a real database table, a pandas DataFrame, or one huge JSON object, the choice is yours! The tricky part is the many-to-many nature of it all (many services can use a feature class, and many feature classes can be part of one service)

# The requests library is necessary for making http(s) calls to REST services
# The keyring library is necessary for obtaining the password for your ArcGIS Server username.  See documentation below.
# The csv library is necessary because the final output for this script is a CSV file.
# The json library is necessary for pretty printing JSON output.  Humans can more easily see property names, values,
# and parent/child relationships

                                # Write the path to the output dictionary, which is typically the name of the ArcMap document or ArcGIS Pro project
                                # which published the service.
                                outionary["Source"] = resource["onPremisePath"]

                            outWriter.writerow(outionary)
âoutfile.close()

The resulting file will likely be stored in the same place as the script. You control the name of the file with the constant outputCSVName in the script.

I hope this post has helped you, even if it has only inspired you to write your own. Feel free to follow me, as I tend to post reusable scripts that help me do my job, and they may help you use yours. And please ask questions if something fails; if I don't know the answer I'll say as much.

I know it's been a while but, wanted to say thank you! This PowerShell script was very helpful. I had to add a .Replace() method to the $service.folderName part of building the $ServiceItem object to account for services in our root folder but, after that it worked great!

Roger,
No worries, and no need.
What I ended up finding after further research is that, no, the ArcGIS REST API provides no way to know the specific dataset used by each layer of a service, for "security reasons". Even if you have full admin access to ArcGIS Server, the API provides no means to extract this information at all.

We were trying to achieve the same outcome finding a relationship between the map service layers and dataset information. We were hitting the same hurdles however while digging around noticed that the .mapx files on the server contain the appropriate layer and dataset information.

We wrote the following using PowerShell to perform the appropriate requests to the ArcGIS REST API as we also needed access to the administrative file share on the server to access the mapx files. The server path was found by retrieving the resources serverPath from the service's manifest.json file.

$Layers | Export-CSV '<csv path>' -NoTypeInformation

This outputs a CSV file with the service folder, name, mapx location, layer name, database connection and feature class.

Hope this is useful to others!

Thanks

Roger,

No worries, and no need.

What I ended up finding after further research is that, no, the ArcGIS REST API provides no way to know the specific dataset used by each layer of a service, for "security reasons". Even if you have full admin access to ArcGIS Server, the API provides no means to extract this information at all.

Therefore I ended up switching to an hybrid solution where I extract what I can from the ArcGIS REST API and then use python, ArcGIS Pro arcpy and the original .mxd project file (used to publish the service) to extract the rest, like the feature class name of the data source used by each layer. It works but we have hundreds of services and using this approach is defitely not has convenient as just making HTTP requests on the API (which could be made from any programming language).

Thanks

Would you happen to know if it would also be possible to know which service layers use which datasets? Like being able to map each dataset to one or more layer names/ids (i.e. array of layers) that uses that dataset? Ideally using only the REST API?

I'm really sorry I'm late replying. I'm at a new job now and I don't think I have notifications turned on my new email address. Anyway, back to your question, when you say "dataset", do you mean the groups of feature classes found in a geodatabase, or as layers in a manifest file?

The manifest does not keep track of which datasets its layers come from, even though it calls feature classes datasets. If your geodatabase has three FIRE_HYDRANTS feature classes, all owned by different owners and in different datasets, then I don't think you'll be able to successfully know which datasets some services are using.

However, if your feature classes are uniquely named, then, yes, you can definitely see which datasets are being used by which services, and which services are using which datasets. Would you like me to write the code for you?

Roger,
Thanks so much for your work and for posting these scripts. This saved a whole lot of time.

This has been extremely helpful

I have rewritten this script. Rather than spitting out a CSV, this new script will report all the services used by a target feature class and all of its siblings in the feature dataset. And it will list the map documents or Pro projects that directly contain the target feature class. Each code block below represents a different cell in my Python notebook, be it in Pro or Jupyter.

Like the previous script, I have imported keyring, and in a different script, I have called keyring.set_password(keyringType, administratorUser, myPassword)

# The requests library is necessary for making http(s) calls to REST services
# The keyring library is necessary for obtaining the password for your ArcGIS Server username.  See documentation below.

# and parent/child relationships

By breaking up the code into testable functions, it is more easily tested at each step. I hope this proves useful to those who find this. Also, I apologize for not providing proper doc strings for each function. I wish to improve, not in documentation (because I'm good at that), but in documenting things the way Python would rather they be documented. Thanks for your support!

This was very helpful for us to go through our services to be able to clean up services that are no longer in use and from some projects that were done in 2016. It was great to be able to see the sources of the data as well. Great work!!

Oh, also remember to save and rename your script afterwards, and to cleanly close down the Jupyter server (DOS window) with Ctrl+C.
