Lizenz
Für den Betrieb von Avantra benötigen Sie eine gültige Lizenz. Die Lizenz wird mithilfe einer Lizenzdatei implementiert, die mit dem Avantra Server verwendet wird. Sie enthält im Wesentlichen die Anzahl der Systeme, die verwaltet werden dürfen, und einen Aktivierungsschlüssel, der die Lizenz an eine Avantra Server-Instanz bindet.
Log-Adapter
A Log Adapter in Avantra provides log entries of arbitrary log sources as an array of standardized sets of key-value pairs.
Log Adapters are used in LogAdapterCustomCheck in order to monitor the content of log files.
Log sources can be either textual log files or the Microsoft Windows EventLog. There are pre-defined read-only Log Adapters for the Windows System Event Log, Oracle Alert Log, DB2 Diagnostics Log, etc., but you also can define your own Log Adapters in order to monitor other log resources.

Log files in the context of Avantra are text files recording certain actions in a structured way. There are applications out there that consider dumping an arbitrary amount of unstructured bytes into arbitrary files as logging. You can try to get a grip on these things defining an appropriate Log Adapter, but your mileage may vary. |
Technically speaking, you can think of a Log Adapter as a regular expression-based parser using named capturing groups. The result is provided as Macros for use in the LOG_ADAPTER Custom Check, but also in the Monitoring Parameters configuring the Oracle Alert Log or DB2 Diagnostic log checks.
