I don't think there is a normal directory for job logs. Generally, they live in the msdb
catalog. When you view a job's history through the GUI, you're effectively looking at something along the lines of the following:
SELECT TOP 1000 *
FROM msdb.dbo.sysjobs sj
INNER JOIN msdb.dbo.sysjobhistory sjs
ON sj.job_id = sjs.job_id;
That said, you should be able to tailor an export of this information to your liking and have your remote support work with that output.
