condor_fetchlog

Retrieve a daemon's log file that is located on another computer

Synopsis

condor_fetchlog [-help $\vert$ -version]

condor_fetchlog [-pool centralmanagerhostname[:portnumber]] [-master $\vert$ -startd $\vert$ -schedd $\vert$ -collector $\vert$ -negotiator $\vert$ -kbdd] machine-name subsystem[.extension]

Description

condor_fetchlog contacts HTCondor running on the machine specified by machine-name, and asks it to return a log file from that machine. Which log file is determined from the subsystem[.extension] argument. The log file is printed to standard output. This command eliminates the need to remotely log in to a machine in order to retrieve a daemon's log file.

For security purposes of authentication and authorization, this command requires ADMINISTRATOR level of access.

The subsystem[.extension] argument is utilized to construct the log file's name. Without an optional .extension, the value of the configuration variable named subsystem_LOG defines the log file's name. When specified, the .extension is appended to this value.

The subsystem argument is any value $(SUBSYSTEM) that has a defined configuration variable of $(SUBSYSTEM)_LOG, or any of

A value for the optional .extension to the subsystem argument is typically one of the three strings:

  1. .old
  2. .slot<X>
  3. .slot<X>.old
Within these strings, <X> is substituted with the slot number.

A subsystem argument of STARTD_HISTORY fetches all condor_startd history by concatenating all instances of log files resulting from rotation.

Options

-help
Display usage information
-version
Display version information
-pool centralmanagerhostname[:portnumber]
Specify a pool by giving the central manager's host name and an optional port number
-master
Send the command to the condor_master daemon (default)
-startd
Send the command to the condor_startd daemon
-schedd
Send the command to the condor_schedd daemon
-collector
Send the command to the condor_collector daemon
-kbdd
Send the command to the condor_kbdd daemon

Examples

To get the condor_negotiator daemon's log from a host named head.example.com from within the current pool:
condor_fetchlog head.example.com NEGOTIATOR

To get the condor_startd daemon's log from a host named execute.example.com from within the current pool:

condor_fetchlog execute.example.com STARTD

This command requested the condor_startd daemon's log from the condor_master. If the condor_master has crashed or is unresponsive, ask another daemon running on that computer to return the log. For example, ask the condor_startd daemon to return the condor_master's log:

condor_fetchlog -startd execute.example.com MASTER

Exit Status

condor_fetchlog will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
