The rvt-gather_diags script collects diagnostic information. Run rvt-gather_diags [--force] [--force-confirmed] on the VM command line.

Option Description


option will prompt user to allow execution under high cpu load.


option will not prompt user to run under high cpu load.

Diagnostics dumps are written to /var/rvt-diags-monitor/dumps as a gzipped tarball. The dump name is of the form {timestamp}.{hostname}.tar.gz. This can be extracted by running the command tar -zxf {tarball-name}.

The script automatically deletes old dumps so that the total size of all dumps doesn’t exceed 1GB. However, it will not delete the dump just taken, even if that dump exceeds the 1GB threshold.
