Recommendations

Database Monitoring (DBM) Recommendations draw attention to potential optimizations and problematic areas across your database fleet.

The Recommendations page in Datadog

How it Works

Datadog analyzes metrics and sample data from DBM to identify your systems’ highest-priority issues. A severity indicator is calculated for each recommendation, highlighting the most impactful areas to focus on. High-severity recommendations may indicate immediate or impending problems, while lower-severity recommendations can be addressed asynchronously to proactively maintain database health.

Recommendation types

Choose your database type to view the supported recommendations:

    Missing Index
    The query’s execution plan performs expensive sequential scans. When detected, Datadog recommends using an index to expedite the query.
    High Impact Blocker
    The query is causing a significant amount of waiting time for blocked queries.
    Function in Filter
    The query calls a function on columns being filtered, leading to expensive sequential scans that can’t take advantage of typical column-based indexes.
    High Row Count
    The query returns a large number of rows in its result set.
    Long Running Query
    The query has durations that have exceeded a threshold of 30 seconds.
    Unused Index
    The index has not been used in any execution plans recently.
    Low Disk Space
    The database instance is running low on disk space.

    Note: The Low Disk Space recommendation is only available for instances hosted on AWS RDS.
