4 Introduction ULtraLog is a HomeSeer HS2 v2.2 plug-in that stores HomeSeer and syslog events to an underlying database in real-time. The built in web interface allows you to query the data making it easier to turn your home automation log data into useful information. Intended Audience This document is intended for the HomeSeer user that has chosen to install and configure the UltraLog HomeSeer Plug-in. UltraLog HSPI Overview How It Works UltraLog listens for HomeSeer and syslog events and inserts the data into an underlying database. Access to the underlying database is provided via built in web pages and a plug-in API. Features Multiple threading allows UltraLog to process HomeSeer and syslog events without disrupting the performance of HomeSeer. Supports HomeSeer triggers based on text or regular expression matches on HomeSeer log or syslog events. Ability to save and recall SQL queries. Logs all events to an OLEDB aware database. Currently supports Microsoft Access (database included), Microsoft SQL 2000 and Microsoft SQL 2005, MySQL and other ADO.Net database providers. Ability to specify custom connection strings. Ability to open and close database connections while plug-in is running. Debugging output to troubleshoot database connection issues. Ability to purge database records after a specified number of months. Error Try/Catch logic to ensure plug-in doesnt fail with an unhandled exception. If you are using an external database, the database watchdog logic will automatically reconnect if the database connection is lost. Web page is non-code behind ASP.Net to allow the user to easily customize the code and interface. UltraLog can insert device status and value changes to the underlying database. This feature and designed for users that need historical data associated with each HomeSeer device. 4

If you need to stop or start the syslog server for any reason, simply click the Enable or Disable button from the HomeSeer Status web page. UltraLog HSPI Triggers UltraLog Log Match This option allows you to trigger a HomeSeer event based on a text or regular expression match within a HomeSeer log event. The following plug-in specific triggers are supported: 1. Look In Log Specifies which part of the HomeSeer log event to search. a. Type Search the HomeSeer log type (e.g. Info, Warning, Error, etc). b. Message Search the HomeSeer message (e.g. Web Server Authorized login). 2. Match Type Specifies what type of string comparison to perform. a. Contains b. Starts With c. Ends With d. Regular Expression 3. Match Value Specifies the text string or regular expression used to trigger the HomeSeer event. 4. Notes Enter text to help you remember what the UltraLog Log Match trigger does. When the UltraLog Log Match triggers, the following HomeSeer variables are updated: 1. LogType Contents the HomeSeer log type. 2. LogMessage Contents the HomeSeer log message. If you specify named or parenthesized regular expression captures, then HomeSeer variables are automatically created based on your regular expression. See UltraLog HSPI Named Captures for more information. The plug-in has built in protection to prevent a trigger from creating an endless loop. 8

9 Screenshot UltraLog Syslog Match This option allows you to trigger a HomeSeer event based on a text or regular expression match within a syslog event. The following plug-in specific triggers are supported: 1. Look In Syslog Specifies which part of the syslog event to search. a. Hostname Search the syslog hostname or IP address. b. Message Tag Search the syslog tag. c. Message Content Searches the syslog message contents. 2. Match Type Specifies what type of string comparison to perform. a. Contains b. Starts With c.
