Grid Engine messages can be found in syslog during startup:

After startup the daemons log their messages in their spool directories.

Qmaster:

$SGE_ROOT/default/spool/qmaster/messages

Exec daemon:

$SGE_ROOT/default/spool/$HOSTNAME/messages

or in syslog, if configured

Rotating and truncating Grid Engine Log Files

Contents

  1. Overview

  2. Variables

  3. Command line parameters

  4. Examples

Sun Grid Engine daemons create log files called "messages" in their respective spool directories. Also, an 'accounting' file and a 'statistics' file is created. A script for truncating log files is found in the following directory:

$SGE_ROOT/util/logchecker.sh

The script is not activated by any of the Sun Grid Engine daemons automatically. It is intended to be edited according to the needs of your site. After customizing the script, you can add an entry to your crontab. The script is can run in verbose mode or completely silently. It can also run in a mode where it only prints what would be done. The script accepts only two command line parameters for overriding the ACTION_ON parameter and the location of the exec daemon spool directory (see below).

Sun Grid Engine Software daemons create log files in the qmaster_spool_dir and execd_spool_dir which are defined in the global cluster configuration, the can be overridden in the local cluster configuration of every execution host (usually this is not done). The directory is usually called 'default', and only if the $SGE_CELL variable is used, 'default' is overridden.

Default location of Sun Grid Engine log files:

<qmaster_spool_dir>/messages
<qmaster_spool_dir>/schedd/messages
<execd_spool_dir>/<hostname>/messages
<sge_root>/<sge_cell>/common/accounting
<sge_root>/<sge_cell>/common/statistics
  

Since these directories can all be located in the same directory hierarchy in a shared NFS filesystem, or the execd spool directories can point to a local directory, it is possible to specify with the ACTION_ON parameter (see below) which 'messages' files should be rotated when the script is called.

Variables

The following variables need to be configured in the script. The "|" character specifies an alternative. All variables in the script must be entered in Bourne shell syntax. So there may be no white space before or after the equal "=" sign.


Command line parameters

The script accepts the following command line parameters:


Examples

  1. All Sun Grid Engine spool directories are shared. You can call the script on any one of your Sun Grid Engine hosts or on your file server.

    set ACTION_ON to "4" in the script. Set other values according to your needs and add the script to your crontab of one of the above machines.
  2. Sun Grid Engine execd spool are defined only through the global cluster configuration, but point to a local directory.

    set ACTION_ON="3". Add the start of the script to all crontabs of your execds in your cluster. On your qmaster machine (or on your file server) add the following call of the script to your crontab:
       <path_to_script>/logchecker.sh -action_on 1
  3. Sun Grid Engine spool directories of execds are defined in the local configuration.
    Set ACTION_ON="2" in the script:

    On your qmaster machine (or on your file server) add the following call of the script to your crontab:

       <path_to_script>/logchecker.sh -action_on 1
    On your exec hosts add the following line:
       <path_to_script>/logchecker.sh -execd_spool
