The Goals of Monitoring
Databases Always Up
No Missed Backups
Never Run out of Disk Space
No Performance Problems
And… achieve all this in the most
efficient way possible

Traditional Monitoring Methods
Utilize Maintenance Plans
Send Both Success and Failure Notifications
Or….no monitoring at all

Issues with the Traditional Method:
Missed Backups:
• Maintenance Plans are modified from All User to selected databases, potentially
leaving new databases without backup.
Stopped SQL Agent:
• Agent does not restart and no jobs run—without your knowledge.
Missed Alerts:
• Too many emails. Multiple success and failure notifications get buried in inboxes.
Time Consuming to Set Up and Maintain:
• Monitoring not centralized: difficult to set up, maintain and update.

Centralized Monitoring Solution:
Gather Data and Alert Process Flow

A Better Method:
Why
Centralized
Monitoring is
Better
 Nothing Slips Through the Cracks: you do not
miss when jobs do not run.
 One Single Email: email displays results across
entire environment-rather than multiple emails lost
in your inbox.
 Easily Scalable: Single set of jobs, rather than
deploying the same set of jobs across 100 servers.
 Historical Data Readily Available: data can be
used for trending and alerting.
 Flexible Framework: the sky is the limit—you
can easily expand and extend monitoring jobs.

Two Different Approaches
Single Tier
Approach
• Components running on
single, centralized
Database Server:
• Meta Data to hold
server, connection strings, jobs to
send alerts, results tables, etc.
• Linked servers to connect to all
destination databases.
• Dynamic SQL Generating
Procedure to run jobs, store
results, and send alerts.
Multi Tier
Approach
• Adds App Server and
additional components:
• Same Data Model: adds
additional tables for scheduling
jobs to run on instances.
• Utilizes Windows Service
Agent to connect, execute
SQL, and send alerts.
• Adds Front End to manage job
maintenance, view alerts, and
generate reports

Usage

Key Syntax:
SQL Query: Gather Database Backup Info

Key Syntax:
SQL Query: Gather Database Failed Jobs

Key Syntax:
SQL Query: Gather Database File Size

Key Syntax:
SQL Procedure: Gather Disk Free Space
Utilize SQL Hidden Procedure:
EXEC master..xp_fixeddrives

Key Syntax:
Detect and Alert SP: Failed Backups/Jobs
 SELECT Last Set of Records from Data Results
Table.
 Use MAX(LASTMOD) value to select
records.
 IF detects SOME records (i.e., where backup
date is older than 24 hours/where job status
indicates failure)
 THEN
 Generate alert email.
 Write records to an Alert table.
Stored
Procedure
Detects failures,
sends alert, and
stores alert history

Key Syntax:
Detect and Alert SP: Disk Space/File Size
 SELECT Current Set of Records from Data
Results Table AND Set of Records inserted X
hours (e.g. 24 hours) ago.
 Use MAX(LASTMOD) value to select both
sets of records.
 COMPARE file size/disk space.
 IF detects SOME records where size increased
by X%...
 THEN
 Generate alert email.
 Write records to alert table.
Stored
Procedure
Detects out of range
conditions, sends alert,
and stores alert history
