Percona Server for MongoDB: Features Overview
summary
Percona Server for MongoDB adds two storage engines (Percona Memory Engine, MongoRocks (RocksDB-based)), audit, external authentication, HotBackup for WiredTiger and MongoRocks, and a rate limiter. The session shows concrete monitoring steps: use db.serverStatus, rs.status and sh.status; track journal flush and checkpoint times, page faults/cache evictions, and WiredTiger 128-ticket behavior; watch connections (1 MB overhead each) and oplog headroom to derive an oplog recovery window. PMM is demoed as a working Prometheus + Grafana stack for these metrics.
