Use Cases
With Keyhole, experienced users should be able to spot performance issues and to determine whether upgrades are needed quickly from a few minutes of testing and analyzing the results. Keyhole supports TLS/SSL connections.
Several features are available, and they are
- Write Throughputs Test measures the MongoDB performance by writing documents at a high rate to a MongoDB cluster.
-
Load test extends the Write throughputs test by issuing different ops against a MongoDB cluster. Stats analytic is also provided
- Memory: resident, virtual, and page faults
- Executor and ops
- Latency: read, write, and command
- Metrics: index keys examined, collection scan, in-memory sort, and ops
- WiredTiger analytic
- Customized load test with a sample document. Uses can load test using their own document format (see simulation.md for details).
- Cluster Info and Sanity Check to display information of a cluster including stats to help determine working set data size.
- Display all indexes and their usages
- Duplicate all indexes to another MongoDB cluster.
- Seed data for demo and educational purposes as a trainer.
- Display ops time and query patterns by parsing logs.
- Display indexes scores of a query shape.
- Monitor WiredTiger Cache in near real time.
- View FTDC Data and scores with a friendly interface.
- MongoDB Atlas API integration.
