Script to list MongoDB collection URI (to map to WiredTiger files)

When tracing I/O to WiredTiger files, like with strace -y, the filenames do not give the collection name:

strace -yy -e trace=pwrite64 -s100 -fqT -p $(pgrep -d, mongod)

Here is a quick script to run with mongosh that gets the URI for all collections:

let results = [];  
const dbNames = db.adminCommand({ listDatabases: 1 }).databases.map(db => db.name);  
// For each database
for (const dbName of dbNames) {  
  const currentDB = db.getSiblingDB(dbName);  
  const collNames = currentDB.getCollectionNames();  
  // Get collectons
  for (const collName of collNames) {  
    const stats = currentDB[collName].stats({ indexDetails: true });  
    // Collection URI  
    if (stats.wiredTiger?.uri) {  
      results.push({  
        id: (stats.wiredTiger.uri.replace(/^statistics:table:/, "")),  
        name: `${dbName}.${collName}`  
      });  
    }  
    // Index URIs  
    if (stats.indexDetails) {  
      for (const [indexName, details] of Object.entries(stats.indexDetails)) {  
        if (details.uri) {  
          results.push({  
            id:(details.uri.replace(/^statistics:table:/, "     ")),  
            name: `${dbName}.${collName} "${indexName}"`  
          });  
        }  
      }  
    }  
  }  
}  
// Sort by the identifier  
results.sort((a, b) => a.id.localeCompare(b.id));  
// Print  
results.forEach(r => {  
  print(`${r.id} ${r.name}`);  
});

This helps me to understand my trace:

• collection-2f934890-bfba-4bf1-8e30-a4983d1e443e is config.image_collection that stores pre/post-image documents for retryable findAndModify operations, enabling idempotent retries across failovers.
• collection-2fb69242-1b95-4a08-9939-23172e5ea178 is config.transactions that tracks session transaction state including startOpTime for active transactions.
• collection-7dc3bad2-7f29-4853-b83a-a0d75ce4091c is local.oplog.rs   which is the capped collection containing all replication operations in timestamp order
• collection-d3c1ce81-a90b-434a-867e-d985cc474e98 is local.replset.oplogTruncateAfterPoint which marks the safe truncation point to remove oplog holes after unclean shutdown (crash recovery)
• collection-af1de828-88d4-462d-8163-138c3e6a94de is config.sampledQueries that stores sampled query shapes for query analyzer and sharding key analysis
