Architecture

This section explains the architecture. The following graphic shows the end-to-end data flow of the Oracle Lightweight Availability Collection Tool.

Availability Data Collection and Online Reporting

Upon installation of the Oracle Lightweight Availability Collection Tool on the monitored host, the tool spawns a daemon (tictimed) that continuously monitors and collects the availability status of the host. This collected availability data is stored in the form of an XML file. The Oracle Lightweight Availability Collection Tool's reporting utility (ltreport) can be used to generate and view command line interface (CLI) based reports from this file. The tool also provides a few XSL sheets to generate HTML-based reports from the datagram (for more information, see ltreport Utility).

Offline Reporting at Oracle

The Availability datagram is picked-up and transported back to Oracle by the Oracle Explorer Data Collector and is stored in Oracle's database. This data is used by Oracle to improve its products and is also available for account managers to communicate improvement opportunities with customers.
