Writing Log Entries

Use the EventSource class to write entries to the standard or custom event logs. Set the ComputerName property to write an event log on a remote computer. Specify the source name, category, event number and type of entry to write. You can also include an array of insertion strings and binary data.

Reading and Backing up Log Files

The EventLog class provides access to the standard or custom event logs. Use the SourceName property to specify the event log to access. You can read event log records as well as backing up logs to file or clearing them. You may also subscribe to an event that’s raised whenever the event log changes. When reading, event log entries are cached internally to speed up access. For advanced users you may specify the cache size and, if reading a log on a remote computer, the message files lookup order.

With the EventLogBackup class you may read event logs that have been saved to file either on the local or a remote computer.

Accessing Event Log Records

The EventLogRecord class represents event log records. It includes properties to access the record number, user name, category number and description, event type, event number and description, time, and data. Message and parameter files are looked up to convert insertion strings into full category and event descriptions. You may also access the raw insertion strings if required.

Configuring Event Logs

The EventLogConfiguration class allows you to read and update the configuration for event logs. Specify the maximum size of the log file, the overwrite mode and period. The EventSourceConfiguration class allows the setting and retrieval of event source configuration information. This includes the various message file paths, category count and event types supported.

XML and CSV Support

A number of support classes are also included for converting events logs to comma separated value (CSV) records and XML. An EventLogMonitor class provides enhanced event log monitoring.
