Listing trace spooling status

Edit online

To display the trace spooling status of a resource manager's trace files, use the lssrc -ls resource_manager command.

For example, to display the trace spooling status of the configuration resource manager's trace files, run this command: 

lssrc -ls IBM.ConfigRM
The following output is displayed: 

(other resource manager information)

/var/ct/IW/log/mc/IBM.ConfigRM/trace.1.sp (7 pages) ->
  /admin/bubbly/Spool.ConfigRM/IW/25384144/c206bc1b07/f224ca38a699a2c/IBM.ConfigRMd
/var/ct/IW/log/mc/IBM.ConfigRM/trace.detail -> spooling not enabled
/var/ct/IW/log/mc/IBM.ConfigRM/trace.summary.1.sp (5 pages) -> /dev/null
The sample output shows that trace spooling is:
  • enabled and on for the resource manager's /var/ct/IW/log/mc/IBM.ConfigRM/trace trace file, and is being spooled to the /admin/bubbly/Spool.ConfigRM/IW/25384144/c206bc1b07/f224ca38a699a2c/IBM.ConfigRMd directory.
  • not enabled for the resource manager's /var/ct/IW/log/mc/IBM.ConfigRM/trace.detail trace file.
  • enabled and off for the resource manager's /var/ct/IW/log/mc/IBM.ConfigRM/trace.summary trace file.
For enabled trace files, the listing shows the first page file name (including the page file .number.sp suffix) to emphasize the fact that spooling is enabled.

Examples

  1. In this example, trace files produced by rmcd (those in /var/ct/.*/log/mc/) are each grouped into nine file sets, with trace records added globally, in a circular fashion: 
    
$ export CT_TR_SPOOL=\ 
"/var/ct/.*/log/mc/.*:ON:9:/data/trc"
    As each file is completed, it is renamed (a time stamp is appended) and copied to /data/trc/cluster_name/cluster_ID/host_name/node_ID/rmcd.
  2. This example contains a second directory pattern in the environment variable, /var/ct/.*/log/mc/IBM.StorageRM/.*, which instructs the trace library to create a nine-file spool group from the storage resource manager's trace files and to store the files under /data/trc: 
    
$ export CT_TR_SPOOL=\
"/var/ct/.*/log/mc/IBM.StorageRM/.*:ON:9/data/trc,\
/var/ct/.*/log/mc/.*:ON:9:/data/trc"
  3. To configure trace spooling for the RMC (Resource Monitoring and Control) daemon that has a trace size of 2 MB, run the following command:
    
cttracecfg -T -a -n RMCD -p "/var/ct/.*/log/mc/.*" -d "/data/trc" -s 2097152 -o on
  4. To delete the trace files from the trace spool area /data/trc if the spool area exceeds a size of 50 MB, run the following command:
    cttracecfg -S -a -n spoolarea_data -d "/data/trc" -i 12 -c 50 -o on
