❔ Connecting to the system resource usage monitor database

Hello! 👋 I am attempting to read and parse the SRU db found at C:\Windows\System32\sru\srudb.dat - From what I'm found, it's an Extensible Storage Engine database, however I haven't been able to find code that actually works to connect to it. The OleDb answers all except saying I don't have the right provider installed, so maybe I just need to change the connection string to something more current, and the Isam answers I've found all fail because the page size does not match the page size of the database for all legal page sizes. I'm hoping someone more knowledgeable than I can point me in the right direction on how I might parse this. Here's the most recent failed attempt

JET_INSTANCE instance;
JET_SESID sesid;

SystemParameters.DatabasePageSize = 8192;

Api.JetCreateInstance(out instance, Guid.NewGuid().ToString());
Api.JetInit(ref instance);

JET_DBID dbid;
JET_COLUMNID columnid;
JET_TABLEID tableid;
JET_COLUMNDEF columndef = new JET_COLUMNDEF();

Api.JetBeginSession(instance, out sesid, null, null);

Api.JetAttachDatabase(sesid, @"C:\Windows\System32\sru\srudb.dat", AttachDatabaseGrbit.None);

Api.OpenDatabase(sesid, @"C:\Windows\System32\sru\srudb.dat", out dbid, OpenDatabaseGrbit.None);

JET_INSTANCE instance;
JET_SESID sesid;

SystemParameters.DatabasePageSize = 8192;

Api.JetCreateInstance(out instance, Guid.NewGuid().ToString());
Api.JetInit(ref instance);

JET_DBID dbid;
JET_COLUMNID columnid;
JET_TABLEID tableid;
JET_COLUMNDEF columndef = new JET_COLUMNDEF();

Api.JetBeginSession(instance, out sesid, null, null);

Api.JetAttachDatabase(sesid, @"C:\Windows\System32\sru\srudb.dat", AttachDatabaseGrbit.None);

Api.OpenDatabase(sesid, @"C:\Windows\System32\sru\srudb.dat", out dbid, OpenDatabaseGrbit.None);
