Thank you for the quick response! The HISTORY_HELPER fix works for me.

Subject: [HTCondor-users] Remote condor_history with multiple Schedd hosts

Â

Hello Experts,

Â

I'm having an issue with condor_history (and the Python binding equivalent) returning blank results for some Schedds. (Version 8.8.5)

Â

We have several Schedds in our pool split across two physical hosts. We consider one of these hosts the "primary" as it contains the default Schedd (i.e. DAEMON_LIST contains SCHEDD). We have specified the name and history file path for this Schedd:

Â

SCHEDD_NAME = gld-default@

HISTORY = /opt/condor/history/gld-default.history

Â

The additional schedds on both hosts follow a similar pattern, for example:

Â

SCHEDD_TROLLS20 = $(SCHEDD)
SCHEDD_TROLLS20_ARGS = -f -local-name TROLLS20 -p 8510
TROLLS20.SCHEDD_NAME = trolls2-0@
TROLLS20.HISTORY = /opt/condor/history/trolls2-0.history

<...>

DAEMON_LIST = $(DAEMON_LIST), SCHEDD_TROLLS20

Â

All config settings, other than the different schedds, are the same on both hosts.

Â

Running 'condor_history -n gld-default@' from a remote host in the pool will return that Schedd's history correctly. Similarly, using -name for any Schedd on the primary host will work as expected. However, specifying the name of a Schedd on the secondary host will return just the header with no results. (e.g. condor_history -n trolls2-0@)

Â

The command is reaching the correct Schedd, because it logs the following in response:

Â

12/17/19 12:18:15 (pid:275016) invoking /usr/bin/condor_history condor_history -inherit -stream-results -match -1 -scanlimit 10000 -constraint true -attributes Args,Arguments,ClusterId,Cmd,CompletionDate,JobStatus,Owner,ProcId,QDate,RemoteUserCpu,RemoteWallClockTime
12/17/19 12:18:15 (pid:275016) Create_Process: using fast clone() to create child process.

Â

The Schedd is also writing the history file correctly, because using condor_history -file instead works. (e.g.Âcondor_history -fileÂ/opt/condor/history/trolls2-0.history)

Â

Any help is appreciated.

Â

Thanks,

Collin
