Postgres Enterprise Manager!u  Community PostgreSQL


u  EnterpriseDB Postgres Plus Advanced Server!

An EnterpriseDB tool for DBAs and Developers to manage, monitor, and tune

large Postgres deployments en masse.

Manage means...!u  Add, change, delete and view database objects

•  Server languages, triggers, stored procedures, functions, operators!•  Postgres clusters, Schemas, Databases, Tables, Views, row data!•  Columns, constraints, indexes, sequences!•  Roles, Users, Rules!

u  Routine DB Maintenance •  Edit configuration files!•  Auto-vacuum Management!•  Log file Browser!•  Lock viewer!•  Server Status!•  Execute SQL!•  Scheduling jobs!


Monitor means...!u  Performance Management (database and OS statistics)

u  Capacity Management

u  Configuration Management

u  Alerts Management u  Team Management

u  Log Management


Tune means...!u  Editing Parameter Configurations

u  Profiling SQL workloads by inspecting SQL workloads to finding slow running queries in need of improved performance

u  Debugging and re-writing queries

u  Creating new new indexes



What is Postgres Enterprise Manager (PEM)?!

An EnterpriseDB tool for DBAs and Developers to monitor, manage, and tune

large Postgres deployments en masse!

It’s the only solution of its kind for PostgreSQL!


u  Distributed Architecture •  Specialized components: Server, Client and Agents!•  Efficient low impact processing that is scalable!

u  Pre-configured customizable settings •  Works right out of the box!•  You are immediately productive!

u  Automatic Bulk Operations Across Multiple Servers •  Eliminates repetitive work!•  Tasks are performed faster and consistently across the infrastructure!

u  Centralized Data Store •  Automatic data gathering into a database for easy manipulation of data!•  Easier consolidated reporting/views and historical analysis!

!

Designed for Large Scale Deployments!


u  Multiple pre-configured views over data with drill down features •  Analyze multiple servers from different data perspectives!•  Faster root cause determination!

u  Centralized Work Console •  One place for all database related activities: managing, monitoring, tuning!•  Less context switching tools maintenance is more efficient & scalable style of work!

u  Results: One DBA can easily manage many more database servers!

•  DBAs are happier!•  Organizations' have reduced expense!•  Organization have better control and efficiency in their database infrastructure!

Designed for Large Scale Deployments!

u  Enterprise Manager Agent •  Installed on each managed machine; collects data on OS and databases!

u  Enterprise Manager Server •  Centralized storage for agent collected data and client dashboards !

u  Enterprise Manager Clients •  User GUI console with global at-a-glance monitoring dashboards and used to

carry out centralized database administration and tuning!•  Fat client and web client!

u  An efficient distributed architecture perfectly suited for large numbers of PostgreSQL servers in multiple locations

PEM Designed for 2 types of Users!

u  Features for DBAs •  Performance Management!•  Capacity Management!•  Configuration Management!•  Alerts Management!•  Team Management!•  Log Management!

u  Features for Developers •  View over all database objects!•  Optimizing Parameter configurations!•  Server Side Debugging of Triggers

and Stored Procedures!•  Performance Management!

Performance Management!




Global Overview

u  Without PEM: •  Manual gathering of statistics by hand, scripts, and tools!•  Creating spreadsheets and formulas!•  Creating charts and graphs for historical trends and future !

u  Results: Unpredictable forecasting results in poor performance, rushed and costly upgrades outside of general data center plans.


Capacity Planning & Forecasting!

u  With PEM:

u  Allows early planning to lower costs, reduce maintenance windows,

avoid performance or downtime issues



u  Automatic collection of desired performance statistics u  Customized selections of what metrics to analyze u  Historical trend analysis over specified periods of time u  Future forecasting of resource consumption and usage u  Custom reports containing both graphical and tabular data



u  Before PEM:

u  No commitment to response times u  No commitment that the appropriate experts will respond u  Lacks complete knowledge of your database


Parameter Configuration Management!

Community mail lists and other users

u  With PEM

u  Response in seconds based on knowledgebase derived PostgreSQL expertise

u  Based on knowledge of your specific database


Parameter Configuration Management!

Postgres Expert


Alert Management!u  Without PEM:

u  Generic solutions not tailored to PostgreSQL u  Inefficient: each alert requires a different query to be executed u  Requires complex manual configuration, hand-written scripts to

gather required data, integration with other tools u  Complicated environment and more skills to learn

Alert Management!


u  With PEM:

u  Tailored solution out-of-the-box designed by PostgreSQL experts u  PEM separates data collection and alerting and does both efficiently to

minimize impact on the monitored system and the PEM server u  Easily customizable and efficient

Team Support!


u  With PEM Team Support:

Log Management!u  Without PEM

•  Write scripts to edit configuration files!•  Test scripts!•  Update scripts!•  Update each server manually!•  Write scripts to consolidate logs ! for easy review!•  Test and update!•  Repeated logins!


Log Management!u  With PEM Log Manager

•  Fast Wizard-based specification and deployment!•  Instant Consolidated Log views!


PEM for Developers!u  Parameter Configuration

u  Stored Procedure and Trigger Debugging

u  SQL Performance Management – SQL Profiler

u  SQL Performance Management – Index Advisor


Parameter Configuration!u  Without PEM


Parameter Configurations - Postgres Expert !


u  With PEM Postgres Expert

Parameter Configurations - Postgres Expert !


Stored Procedure / Trigger Debugging!



u  Number one cause of most database problems is poorly optimized SQL code

u  Postgres Enterprise Manager provides multiple tools:

•  SQL Profiler captures a SQL workload over time to locate your slowest running SQL queries!

•  Query Metrics view shows a query’s performance in relation to other SQL in a captured workload!

•  Index Advisor suggests and/or implements new indexes on tables based on queries you run against the table!

SQL Performance Management!

u  Without SQL Profiler:

u  Set config parameter to log long-running queries + server log scraping + pgFouine report…then re-run top queries using EXPLAIN; a slow manual process to find problem queries and interpret results; difficult using multiple tools


SQL Profiler!


Duration: 122 seconds

u  With SQL Profiler:

u  Manual or scheduled SQL captures by user or database, with sorting and filtering of key performance metrics results.

SQL Profiler!


u  With SQL Profiler:

u  Customized views of performance statistics of interest.

SQL Profiler!


u  Trace Metrics compare individual queries against the entire trace:

u  Individual Query statistics within the context of multiple queries run during the trace.

SQL Profiler!

Index Advisor!u  Integrated to work with the SQL Profiler u  Suggests new indexes if the query can be improved

u  Provides the SQL syntax for adding the new index to a table u  Will optionally add the index for you on request



In Summary...!

u  Features for DBAs •  Managing database objects!•  Routine Maintenance!•  Performance Management!•  Capacity Management!•  Configuration Management!•  Alerts Management!•  Team Management!•  Log Management!

u  Features for Developers •  View over all database objects!•  Optimizing Parameter configurations!•  Server Side Debugging of Triggers

and Stored Procedures!•  SQL Profiler!•  Queries Metrics View!•  Index Advisor!

An Enterprise class tool for DBAs and Developers to manage, monitor, and tune

large Postgres deployments en masse.

How can I learn more about PEM?!


u  What versions of PostgreSQL and Postgres Plus can be managed by Postgres Enterprise Manager Agent? •  PostgreSQL versions 8.2 and higher!•  Postgres Plus Advanced Server versions 8.3r2 and higher!•  OS: Linux32/64, Windows and Solaris (x86 and SPARC)!

u  If PEM is built on pgAdmin, is it open source software too? •  No. PEM is EnterpriseDB intellectual property including the combined pgAdmin

functionality.!•  pgAdmin is distributed under a “PostgreSQL License” which allows EnterpriseDB

to do this.!

u  What OS platforms does the Client support? •  Linux, Windows, HP-UX servers and!•  Windows and Linux clients!!!
