[Netarchivesuite-users] NAS/Heritrix doesn't obey byte limits

Thanks, Tue

The crawl.log file has one line for each URL which Heritrix has tried to fetch, I assume.

But that file (and surrounding files) seem to disappear when the job is done, right? So you have to monitor during harvest?

Hello Peter

In the H3 crawl.log.

You can find it during the harvest  f.x. here:
harvester_low_8090/307071_1552863418226/heritrix3/jobs/307071_1552863418226/logs/crawl.log
or  in Netarchivesuite GUI under the job reports

It will tell you why  ☺

Best regards
Tue

Hello Tue!

Not much, the ones that I’ve seen. Which kind of log/filename should I check? Should we change log level? How? What should I look for in the log?

(I’ve got sysadmin and programming experience but I’m new with this system. So I’m eager to learn more!)

Hello, NAS users and others!

We are experiencing a very strange behavior from NAS/Heritrix (see attached Excel file, with comments):

The harvests reports says ”Stopped due to … byte/object limit reached" at very different levels – sometimes much above (more than five times the limit), sometimes much below the limit. We fail to see any pattern in this, it seems more or less random.

What are we doing wrong? Is it some error in the harvest template? (Attached below each table.)

Or, if it is some kind of bug, are there workarounds?

We would much appreciate any hints, as this is quite a problem for us, both for the on-going selective harvests and the upcoming big snapshot run!

(We are running version 5.4.2, I hope that it doesn’t affect this problem, as we can’t upgrade now.)

Best regards,
