Samples Available

This section describes the monitoring samples that are included with Application Center. These samples include additional performance counters that you can install and configure for the Application Center performance chart and database monitoring samples that you can modify and use to monitor your database in the Monitors view and the performance chart.

Database Monitoring Samples

The database monitoring samples consist of six ASP applications and one .mof file. You can change these to reflect your database situation and use them to monitor your database.

 Caution   To use these samples, you must be running SQL Server version 6.5 or later with Service Pack 2.

The ASP Files

The six ASP files provide five different monitoring tasks. Error checking procedures pass any error information back with the HTML page returned by the ASP application. These application check to ensure the following:

• That the connection is functioning.

• That the database is both connected and functioning.

• That the database server can call stored procedures.

• The Data Source Names (DSNs).

 Note   These samples are designed to work with Application Center Events and Performance Logging and might need modification to work with other types of databases.

• Helloworld.asp—confirms you database functionality by calling a stored procedure on your database that returns the message "Hello, World" upon completion. It creates an ADO database connection and calls a stored procedure with a parameter.

• Verifysp.asp—performs the same test as Hellowworld.asp, except that it uses information passed in a query string to call the stored procedure.

• Adotest.asp—checks ADO functionality by querying an Application Center table for a known value. It creates an ADO database connection and uses a SQL query.

• Eventclassescount.asp—performs the same test as Adotest.asp. It creates an ADO database connection and uses a SQL query.

• Serverlist.asp—checks basic functionality by using a query against an Application Center table to form a list of the cluster members. It creates an ADO database connection and uses a SQL query.

• Dnseventclasses.asp—checks DSN functionality by using a DSN to connect to your database and return results. It uses a SQL query.

   Note   To use Dnseventclasses.asp, you must create a DSN.

• Samples.mof—creates and registers classes in WMI. Samples.mof is compiled and registered during set up. These WMI classes define data groups, data collectors, thresholds, actions, and performance counters.

Additional Performance Counters

You can add the additional performance counter samples to the performance counters that are already monitored and displayed by Application Center. To use these counters, you must either run Application Center Setup, and select only the optional samples, or you can compile Samples.mof.

Additional Web Service Counters

You can use the additional performance counters listed in the following table for monitoring Web services and resources:

Object	Counter
ASP pages	Request Execution Time, Request Wait Time, Requests Executing, Sessions Total, Transaction/sec, Template cache hit rate
Distributed Transaction Coordinator (DTC)	Transactions/sec
Global IIS	File Cache Hits %, File Cache Flushes
Process	% Processor Time, Thread Count
W3Svc Service	Not found errors/sec, Current anonymous users, Non-anonymous users/sec, Maximum connections, Post request/sec, Bytes Sent/sec for, Files Sent/sec for, ISAPI extension requests/sec

Additional System Counters

You can use the additional system counters listed in the following table to monitor the operating system and services:

Object	Counter
Memory	Page reads/sec
Physical Disk	Reads/sec, Writes/sec, % Disk Time
Processor	Interrupts/sec, % DPC time
Server	Logons/sec
System	Processor Queue Length

Additional SQL Server Counters

You can use the additional SQL Server counters listed in the following table for monitoring SQL Server performance and availability:

Object	Counter
Access Methods	Table Lock Escalations/sec
Buffer Manager	Page Reads/sec, Page Writes/sec, Buffer Cache Hit Ratio, Free Buffers
Databases	Data File(s) Size (KB), Percent Log Used
General Statistics	User Connections
Locks	Number of Deadlocks/sec
Memory Manager	Total Server Memory, Lock Memory
SQL Statistics	SQL Compilations/sec, SQL Re-compilation/sec, Failed Auto-Params/sec
Physical Disk	Avg. Disk Queue Length, % Disk Time, Disk write bytes/sec, Disk read bytes/sec
Memory	Page Faults / sec
Processor	% Privileged Time, % Processor Time, Processor Queue Length

Additional COM+ Counters

You can use the additional COM+ counters listed in the following table primarily for monitoring COM+ applications. You must alter this file before you can compile and use it. The following counters are associated with this file:

Counter	Instance
Total Committed Transactions	application_name
Committed Transactions/sec	application_name
Total Aborted Transactions	application_name
Aborted Transactions/sec	application_name
Total Object Creations	application_name
Object Creations/sec	application_name
Total Object Activations	application_name
Object Activations/sec	application_name
Total Shutdowns	application_name
Timeout Shutdowns	application_name
Admin Shutdowns	application_name
Failure Shutdowns	application_name
State	application_name

Additional Miscellaneous Counters

You need to do some configuration of the additional counters listed in the following table before you can use them. You can make these changes in the Health Monitor snap-in. The following counters are associated with this file:

Object	Counter
Network Interface	Bytes total per second, Bytes received per second, Bytes sent per second
Processor	% Processor Time
Process	% Processor Time, Thread count

Monitors and Counters for BizTalk Server

Some monitors and performance counters are also included for use with Microsoft BizTalk™ Server. These can be used to monitor your BizTalk servers by using Application Center or Health Monitor and can be found in the Health Monitor data group BizTalk Server 2000 Sample Monitors under Samples.

The monitors and counters include:

• BizTalk Messaging Service Perf Counter Monitors – monitors performance counters specific to BizTalk Server.

• Suspended Queue Event Monitors – checks for documents in the suspended queue.

• BizTalk Messaging Service Monitor – checks the status of the BizTalk Messaging Service.

• Pipelines performance counters – lists total pipeline executions and errors.

• Marketing and Catalog performance counters – LRUCache: Cache size, LRUCache: Flushes/sec, LRUCache: Hits/sec, LRUCache: Misses/sec.

Some of these monitors do not have supplied thresholds. You will need to create the thresholds according to your specific environment.

Additional Monitors

You can add the additional monitor samples to those already monitored and displayed by Application Center. The .mof file that defines them is compiled during Setup when you install the samples.
