This application is designed to enhance the efficiency of MongoDB database administrators (DBAs) and developers by automating the process of identifying slow queries, redacting sensitive information, and providing index suggestions using advanced AI capabilities.

• MongoDB Query Profiler Integration: Connects to your MongoDB instance and retrieves slow query data from the system.profile collection.
• Redaction of Sensitive Information: Analyzes the retrieved MongoDB queries, redacts sensitive information, and presents them for further analysis.
• AI-powered Index Suggestions: Leverages AI capabilities to generate index suggestions based on the extracted MongoDB queries, aiding in optimizing query performance. Currently supported AI providers: OpenAi, Ollama

Ollama allows you to run open-source large language models and keep privacy. Setup:

ollama run llama3

To set up authentication, follow these steps:

mongosh

use admin
db.createUser({
  user: "mongodb-index-advisor",
  pwd: passwordPrompt(),
  roles: [ { role: "clusterMonitor", db: "admin" } ]
})

docker run --rm -it --net host andriik/mongodb-index-advisor -aiProvider ollama -dbName rto -mongoURI "mongodb://mongodb-profiler-exporter:<password>@127.0.0.1:27017/admin?authSource=admin&readPreference=primaryPreferred"

There are two ways to enable profiler in mongodb:

use db_name
db.getProfilingStatus()
db.setProfilingLevel(1, { slowms: 100 })

operationProfiling:
  mode: slowOp
  slowOpThresholdMs: 50

The default size of the system.profile collection is set to 1MB, which can be insufficient for certain scenarios. To address this limitation, you can adjust the size of the collection by recreating it. Note that this process should not be replicated to replicas.

Below are example commands that can be used to increase the size of the system.profile collection:

db.setProfilingLevel(0) // Disable profiling temporarily
db.system.profile.drop() // Drop the existing system.profile collection
db.createCollection( "system.profile", { capped: true, size: 1024 * 1024 * 50 } ) // 50Mb
db.setProfilingLevel(1, { slowms: 100 })  // Enable profiling again
