When your databases support mission-critical applications, latency and outages can hurt your business. That’s why you need monitoring and management tools to help you keep your enterprise Postgres servers — and the applications they support — consistently available and consistently fast. In this webinar, you’ll learn: The various tasks — monitoring, administration, etc. — required to keep a database server working well, and how they differ Why it’s hard to monitor databases with general-purpose monitoring tools The main tools available for enterprise Postgres needs How these solutions differ, and when and why to choose each of them for specific cases By the end of this session, you will have an understanding of how to avoid downtime and optimize the user experience with database monitoring tools.

4. PostgreSQL is HOT

...by 2022, more than 70% of
new in-house applications will
be developed on an
open-source database

5. BENEFITS OF MONITORING
CONFIDENTIAL © Copyright EnterpriseDB Corporation, 2019. All rights reserved.5
•Time & Resources •Capacity Planning •Availability •Performance
USER EXPERIENCE MANAGE COSTS AVOID DOWNTIME

6. DATABASE MONITORING IS DIFFERENT
6
You can restart most apps
when they fail, but not
databases because they’re
durable or stateful
Stateless vs Durable
Range and timing of
workloads (CRUD, data
warehouse, analytics, month
end) varies tremendously
Variable Workload
Telemetry is beyond just
time series data: SQL,
EXPLAIN plans, etc.
Doesn’t fit into
simple monitoring
data models

9
Did the backup complete successfully?
Which queries are consuming the most resources?
Is replication running and up-to-date?
Why is the app encountering slow queries sometimes?
Did auto vacuum run? Are databases bloated?
Are configuration settings optimal?
When will I run out of disk space?
What user accounts exist?
What is the schema (tables, data types, indexes…)?
And many more...

conditions such as a metric
crossing a threshold, and
generate alerts and notifications.

14. QUERY
PERFORMANCE
These tools are query-focused and help you
understand the database’s workload and how it’s
performing, from the client’s perspective.

You can also use Application Performance
Monitoring tools*
• New Relic
• AppDynamics
• Dynatrace
• Datadog APM
* These tools are app-centric, not DB-centric

15. REPORTING &
ADMINISTRATION
These tools enable DBAs and operations staff to do:
• Administrative tasks like defining
tables/indexes/datatypes, adding users, inspecting
status
• Ad-hoc interactions like querying the database to
run a report or edit the data in a table

16. GENERAL
PURPOSE
MONITORING TOOLS
• These tools typically scrape status metrics
from the server and store them in a time series
database for charting and trending
• They often have the ability to send alerts
based on thresholds
• They shine when you want to use one tool to
monitor as many things as possible
