The tpm diag command will create a TGZ file including log files, current dataservice status and a number of OS metrics.
shell> tpm diag
NOTE >> host1 >> Diagnostic information written to /home/tungsten/tungsten-diag-2013-10-09-21-04-23.tgzThe operation of tpm diag differs between installation types (Staging vs INI). This is outlined below:
With Staging-method deployments, the tpm diag command can be issued in two ways:
The tpm diag command alone will obtain diagnostics from all hosts in the cluster.
The tpm diag --hosts host1,host2,hostN command will obtain diagnostics from the specified host(s) only.
Within an INI installation, the behaviour will depend on a number of factors, these are outlined below
For versions prior to 5.3.7, and version 6.0.0 to 6.0.4
For versions 5.3.7 to 5.4.0, and versions 6.0.5 onwards
The tpm diag command alone will ONLY obtain diagnostics from the local host on which the command is executed.
The tpm diag --hosts host1,host2,hostN command will obtain diagnostics from the specified host(s) only.
The tpm diag -a|--allhosts command will attempt to obtain diagnostics from all hosts in the cluster if ssh has been configured and the other hosts can be reached. The output of tpm diag will provide feedback detailing the hosts that were reached.
The structure of the created file will depend on the configured hosts, but will include all the logs for each accessible host configured in individual directories for each host.
Additional options
It is possible to limit the amount of information gathered by tpm diag by optionally skipping individual gather subroutines, or skipping entire groups. These are outlined below
--list : Print all diagnostic gathering groups and
associated subroutines for use with --skip and
--skipgroups
--skip : Specify a comma-separated list of
subroutines to skip (NO spaces)
--skipgroups : Specify a comma-separated list of
subroutine groups to skip (NO spaces)
Examples
shell> tpm diag --list
GROUP: SUBROUTINE(s)
cluster: cctrlClusterValidate cctrlHistoryFile cctrlLong cctrlPing cctrlStatus

shell> tpm diag --skip=getOSCommands
shell> tpm diag --skipgroups=os
tungsten_send_diag
If the host you are running the diag from has external internet connectivity, you may also wish to consider using tungsten_send_diag. This will run tpm diag for you and automatically upload the resulting file to Continuent Support. For more information on using this, see Section 9.44, “The tungsten_send_diag Script”
