From an AGOL hosted feature service, there is the very neat "Usage" tool. How does one access this programatically, e.g via python or the REST API? This is some very useful data, but having to visit a large number of service definition pages, individually, is not very effective. We'd like to be able to query and report of service useage statistics for all hosted feature services within the organization. We do NOT consider "Number of Times Viewed" a very reliable counter, as that is not capturing hits to the service that are originating from other apps, such as web map or geojson query. ...

There are about as many opinions and resources on SQL Spatial Index Tuning as there are on why the use of a Sequential GUID is good or bad. There's The Black Art Of Spatial Index Tuning In SQL Server | boomphisto , ArcGIS Help 10.1, Spatial Indexing Overview , Spatial Indexing: From 4 Days to 4 Hours - CSS SQL Server Engineers - Site Home - MSDN Blogs, sp_help_spatial_geography_histogram and Indexing geography data in SQL Server Denali | Alastair Aitchison , Basic Multi-Level Grids - Isaac @ MSDN - Site Home - MSDN Blogs , http://social.technet.microsoft.com/wiki/contents/articles/9694.tuning-spatial-point-data-queries-in-sql-server-2012.asp… ,  and of course, if you've ever struggled with a poorly-performing spatial index and posted about it on the internet, chances are you got a reply from this guy. Unfortunately, most of us are not database programmers, nor do we dream in SQL syntax. SQL is like learning French by reading a Chinese dictionary. I don't know about you, but I can't make heads or tails of one single line of SQL code. I'm happy to copy other peoples SQL snippets and hack them up 'till I get them to work. I particularly love this statement from ArcGIS Help: "If you create your data through ArcGIS for Desktop, the spatial grid index is calculated for you." That's like saying "If you put your key in the ignition, your car will drive to the store, get milk, and NOT kill a raccoon on the way". Unless your a Massachusetts driver, there are obviously a few things you have to tweak, such as turn the steering wheel and press the gas paddle in endlessly unique combinations in order to get to the milk store and swerve to avoid the raccoon. The same goes for SQL Spatial Indexes in a SDE Database. Just because the software enables them out of the box by no means implies that the index is optimized for your particular data environment. Out of the box, ArcGIS creates a spatial index with 16 Cells Per Object with all four levels set to Medium Grid Levels. Notice how the storage type is Goemetry, which some of you are discovering is the "New" ESRI default storage format. Let's see how the "Out of the Box" spatial index performs. One way to test a spatial index "Quick and Easy" is with the Spatial Index Stored Procedures. CREATE SPATIAL INDEX --THIS IS THE DEFAULT NAME OF THE INDEX --CREATED BY ARCGIS [S1169_idx] ON --AND THIS IS THE NAME OF TABLE --SUPPLIED BY THE USER IN ARCGIS --AT CREATION TIME [dbo].[TEST_GEOM] (   [SHAPE] )USING  GEOMETRY_GRID WITH (BOUNDING_BOX =(227166.13, 3925740.74, 314851.6915, 3968047.64), GRIDS =( LEVEL_1 = MEDIUM, LEVEL_2 = MEDIUM, LEVEL_3 = MEDIUM, LEVEL_4 = MEDIUM), CELLS_PER_OBJECT = 16, PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, --DROP_EXISTING = ON ALLOWS US TO DO THIS ALL --DAY WITHOUT MESSING WITH DROPPING THE IDX DROP_EXISTING = ON, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) ON [PRIMARY] GO DECLARE @geom geometry --THE POLYGON IS AN AREA SMALLER THAN THE BOUNDING BOX SET @geom = GEOMETRY::STGeomFromText('POLYGON ((247804.201 3943957.896, 29932.568 3943963.210, 247671.344 3942876.441, 247684.630 3943652.325,247804.201 3943957.896))', 26917)jjj exec sp_help_spatial_geometry_index 'TEST_GEOM', 'S1169_idx', 1, @geom There's a WHOLE lot of output. The first thing my eye spies is Primary_Filter_Efficiency 19.634703196347 and Internal_Filter_Efficiency 0 I'm no expert on SQL or spatial indexes, but I don't think those numbers look good. No wonder my draw times are slow, spatial queries are sluggish, and in general, the database is performing horribly. Every single ArcGIS-created table has the same index parameters! Just for giggle, lets change the cells per object by altering just this in the above code snippet: CELLS_PER_OBJECT = 4096 And look at the increase in efficiencies! Internal_Filter_Efficiency 76.7441860465116 Primary_Filter_Efficiency 91.4893617021277 Again, I'm claiming to be no expert at SQL Spatial Index Tuning, but I think I'm on to something here. As it turns out, my test data consists of "Very Complex Line Strings", which, if you're not living under the GIS rock, that's what all of your data is. Coincidentally, using value of 8192 for Cells Per Object in this scenario is a good starting point. But there's a lot (lots and lots) of values between 16 and 8092, and then there's all the permutations of Low, Medium, and High that could be tested to determine the spatial index that is likely to give you the best performance most of the time. What if there was a way to automatically test spatial index settings and magically determine which parameters best fit your data scenario? Enter the SDE Hacker.... I stumbled across this geospatial - Selecting a good SQL Server 2008 spatial index with large polygons - Stack Overflow  post where someone had posted a SQL stored procedure that will loop through Cell Sizes and Grid Levels to report Spatial Query results for every permutation (user supplied). Being the tinker that I am, I of course broke the code trying to add a bunch of output. Finally got it working.

70.2127659574468 This post doesn't even scratch the surface of Spatial Index Tuning.

You also want to look at other performance factors such as Internal Filter Efficiency. There's a lot of Witch Magic and Snake Oil Medicine to Spatial Index Tuning.
