Overhead

Deployment
• Deploy and Manage any type of MongoDB implementation
– Replica Sets
– Sharded Environments
– Standalone Server
• Designed to support a Wide Variety of architectures
– Public Cloud
– Private Cloud
– Bare Metal
• Allows for detailed parameter tuning

No Down-Time Modification
• Modify your MongoDB deployments with no down-
time
– Sharded Environments
– Replica Sets
• Example operations: (Not Exhaustive)
– Version upgrades and Downgrades
– Resizing Oplog
– Change Startup Parameters
– Build Indexes
– Change Listening Ports / Storage Engine
– Enable Profiler
– Tune Storage Engine Parameters
– Change Log Verbosity
– Change member priority / Vote / Replication
Delay
Effortless Best Practices

Painless Scaling
• Scale for throughput
– Expand a Sharded Environment
• Scale for availability/DR
– Add Members to a Replica Set
• Migrations
– Add Members to a New DC to
retire old ones
• Just a few simple clicks
Meet the Demands

Performance Monitoring
• Platform Specific Metrics
– 100+ MongoDB metrics
• Different zoom levels
– Macro View (Cluster, RepSet) Stacked.
– Individual Node View
– Database specific view
• Extensive Granularity Levels – Down to the Min
• Examples: (Non Exhaustive)
– OpCounters
– Cache Usage
– Queues
– Page Faults
– CPU Time
– Oplog GB/Hour
Quickly Derive Performance Insights

Issue Isolation Capacity Planning
Metrics for Issue Isolation:
• Cursors
• OpCounter
• Replication Lag
• Queues
• Page Faults
• Connections
• Network
• Cache Usage
• Page Faults
Metrics for Capacity Planning:
• DB Storage
• CPU Time
• Network
• OpLog GB/Hour
• Number of DB objects
• Storage Size
• Data Size
• OpCounters

Query Perf. Visualizations & Optimization
Fast and simple query optimization with the
new Visual Query Profiler
• Query and write latency are consolidated and
displayed visually; your ops teams can easily
identify slower queries and latency spikes
• Visual query profiler analyzes the data it displays
and provides recommendations for new indexes
that can be created to improve query performance
• Ops Manager and Cloud Manager can automate
the rollout of new indexes, reducing risk and your
team’s operational overhead

Alerting
• Establish Alerts based on Metrics/Baselines
• Specify by Server Type
• Specify the Alert Target
• Specify Alert mechanism
– SNMP
– Email
– HipChat
– Slack
– FlowDock
– PagerDuty
• Specify Alert Let-Off
Be proactive with Alerting

Integrations with APM Platforms
Easily incorporate MongoDB performance
metrics into your existing APM dashboards
for global oversight of your entire IT stack
• MongoDB drivers enhanced with new API that
exposed query performance metrics to APM tools
• In addition, Ops and Cloud Manager can
complement this functionality with rich database
monitoring.

Online Backups – PIT Restore
• Ops Manager performs Online backups
• Offers PIT recovery
• Offers Automated Restore options
• Storage Medium options:
– BlockStore (MongoDB Database)
– Specified File system
• Permits specifying custom retention policies
• PIT recovery for up to 1yr
• Fully supports Replica Sets and Sharded
Environments
• Supports Namespace Filtering
Effective Backup and Restore Strategies

Centralized Authentication/RBAC Management
• Manage Users and Roles
• Deploy Users and RBACs based on
system membership in Ops
Manager
• User/Roles Defined will
automatically propagate to all
systems in that Ops Manager group
• Supports External Authentication
configurations
Making Security Easy and Automatic
