Welcome

PolyMon is an open source system monitoring solution that can be used to generate email alerts and analyze historical trends of monitor counters and monitor statuses. It is based on the .NET 2.0 framework and SQL Server 2005.

It is simple to use and run but flexible enough for many circumstances.

It is made up of three primary components:

• A SQL Server database to store monitor statuses, alerts and general settings.
• A windows service (PolyMon Executive) that runs monitors on a periodic basis, logs results to the database and sends out email notifications.
• A management/monitoring front-end (PolyMon Manager) that is used to manage general settings, monitor definitions, operators, alert rules, etc. and analyze historical trends (both monitor counters and statuses).

Current monitor plug-ins:

• CPU Monitor
• Disk Monitor
• File (Age and Counts)
• Windows Performance Counters Monitor (built-in Performance Counter browser)
• Ping
• PowerShell Scripting
• SQL Monitor (Can run any stored procedure that returns resultsets in a specific format)
• SNMP Monitor
• TCP Port Monitor
• URL (HTML) Monitor
• URL (XML) Monitor
• Windows Service Monitor
• WMI Monitor (built-in WMI browser and query builder)

Monitors are built using a plug-in architecture and can be added to PolyMon without requiring a recompile of the application. New plug-ins simply need to inherit from a base class. Once compiled and placed in the appropriate directories, new monitors are registered with PolyMon using a plug-in registration form in PolyMon Manager.

In addition, users can create completely custom monitors by using PowerShell scripts. PolyMon now integrates PowerShell scripting allowing Status and Counter information to be passed back from a PowerShell script to the PolyMon PowerShell Monitor. This essentially provides PolyMon a complete integrated scripting language for custom monitoring. Furthermore, because these monitors are created using PowerShell you have full control over what actions to take in the event of a Warning or Failure state.

All questions and suggestions are welcome! Also more than welcome would be suggestions for new monitor types.

Thanks and please let me know if you find PolyMon useful!
