Overview
The task of collecting the support data is performed by a background CLI task called the record collector. The
administrator configures the SDC via the CLI with the commands to be executed on a periodic basis. The
record collector always runs in the background and checks if there are records to be collected.
When it is time to collect support data, the scheduler executes the configured sequence of CLI commands and
stores the results in a gunzipped (.gz) file on the hard-disk. This file is called an SDR (Support Data Record),
and represents a snapshot of the overall state of the system at that time.
Technical Assistance Center (TAC) personnel and local administrators can review the SDRs on-line or by
transferring them off the system. They may also wish to investigate the collector state information. The figure
