MongoDB Ops Tool

The MongoDB Ops tool gathers collection level query/insert/update/delete counters to assist in the process of sizing.

Requirements

• Python 3.7+
• PyMongo
  • MongoDB 2.6 - 3.4 | pymongo 3.10 - 3.12
  • MongoDB 3.6 - 5.0 | pymongo 3.12 - 4.0
  • MongoDB 5.1+ | pymongo 4.0+
  • DocumentDB | pymongo 3.10 - 4.0

Using the MongoDB Ops Tool

python3 mongodb-ops.py --uri <mongodb-uri> --server-alias <server-alias> --collect

• Produces an output file for comparison

python3 mongodb-ops.py --compare --file1 <first-compare-file> --file2 <second-compare-file>

• Compares the results of two executions to estimate the number of queries, inserts, updates, and deletes per second at the collection level.

Notes

• Run on any instance in the replicaset (the larger the oplog the better)
• If sharded, run on one instance in each shard
• Each execution creates a file starting with <server-alias> and ending with .json
• The <mongodb-uri> options can be found at https://www.mongodb.com/docs/manual/reference/connection-string/
• Use &directConnection=true
