condor_fetchlogcontacts 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 ADMINISTRATORlevel 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 .extensionis appended to this value.

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




A value for the optional .extensionto the subsystemargument is typically one of the three strings:

1. .old

2. .slot<X>

3. .slot<X>.oldWithin these strings,  <X> is substituted with the slot number.

A subsystemargument of STARTD_HISTORYfetches all condor_startdhistory by concatenating all instances of log files resulting from rotation.

condor_fetchlog STARTD

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