The EPO Addon probes are provided as much as possible in a suitable scriptingformat. With this open source view we hope to encourage you to make you're own probes. As a result we hope that in return you will upload the results of your own creativity. You will experience that the EPO-community not only is interested in using these new probes but also that where possible/applicable these new probes will be adapted to be even more powerfull or more effective.

If you have questions about making your own probes don't hesitate to join the forum with your questions!

*** EXAMPLE PROBES ***

Backuplog. This probe is written in Visual Basic script. It can be used whitout modifications to the code for monitoring backuplogs and report the text you want to see. This backuplogprobe will read the actual backuplog (plain ASCII or HTML) and report to EPO the text that you specify in the configuration of the probe (refer to the readme.txt for how to use the script). You can also specify the EPO-state of the test (normal, warning or critical) depending on the interpretation of the text that was found in the backuplog. This probe can also be used if the backuplog is retrieved as an HTML-page.
The code can also be used as an example on how to write your own probes.

File Age. This probe is written in Visual Basic script. It can be used whitout modifications to the code for checking if a file is older then a specified period. You can use this probe for functional testing if a file is renewed. By example: testing if a exportfile is actually refreshed. This in stead of only checking the existance of the technical process (or job) that should supply this exportfile.

Number of Files. This probe is written in DOS-commands. It can be used to monitor the number of files in a specified directory. For example if you want to be notified if an application dumps too many (error)files. You can also adapt this script to monitor similar situations.

SQL Server Statistical information. This probe is written in DOS and SQL-commands. It can be used to retrieve performance information from databases. The example retrieves the sent packets from SQL Server. It is an performance variable indicating the the number of output packets written to the network by SQL Server. It can easely be alltered to retrieve other global values from Microsoft SQL Server like @@PACK_RECEIVE, @@CPU_BUSY, @@IO_BUSY. See the microsoft SQL Server documentation for more values and information.

SQL Server Database Avalability. These probes are written in SQL-commands. They can be used (even without altering) to retrieve information from SQL Server about the status of the databases. The example probes are installed/copied during the installation in the directory ...\The Early Warning Company\EPO\Script Examples.
File: MSSQL.DatabaseAvailablityCheck.sql - checks result of all databases and reports in EPO to one overall state (=datakey).
File: MSSQL.DatabaseAvailablityCheckPerDB.sql - checks result of all databases and reports in EPO to individual states
File: MSSQL.DatabasesAvailabilityReport.sql - checks result of all databases and reports in EPO to a textual summary

SQL Server database value. This example retrieves a specific recordcount from a specified database tabel. This example can easely be adapted to use it to retrieve actual selling figures, number of incidents or last update time in the database.
File: MSSQL.NumberofRecords.sql.

*** TIPS ***

If you want to find script examples for various topics, take a look in the Script Repository of Microsoft Technet or on the ActiveXperts-page.
An other fine place to look is the "Hey, Scripting Guy!"-page on the Microsoft Scripting Center, where common scripting questions are discussed and explained.
NB Don't forget to use the '//x'-parameter if you want to trace (requirement: MS Studio) Visual Basic scripts! (ie: cscript.exe vbscript.vbs param1 param2 //x)
