[Geoserver-devel] Viewing logs from the web admin GUI

GeoServer GeoServer Developer
1

Hi,
it is common experience that people have to consult logs
in order to debug GeoServer or just see something about
the latest requests flow.

At the moment the only way is to drop on the command line/remote
terminal and open the log files manually.

I have a little patch that integrates a log viewing page.
The page is really simple, it will scan the log file and report
in a read only text area the last N lines of the log file.
See the attachment.

What do you think, useful? Ok to commit?

I'm also attaching the patch (minus the menu icon, which is
page_white_text.png coming from the Silk set) for anyone
interesting in reviewing or improving the page.

Cheers
Andrea

Woo hoo! Definitely useful, one of the features I've wanted since GeoServer 1.2 or so...

+1 from me too (the number of times I've struggled to teach a remote
student where to look for the log)

Very nice indeed.

Perhaps as a future enhancement we could add some sort of "download log" utility. Where the entire log is compressed and sent back to the client. Be a nice way to help users submit bug reports.

Andrea, you are a new feature and patching machine. :slight_smile:

About the only thing I think could be a nice bonus to this is an Export button. Or, going crazier, an Export dialog with options for how many lines (or what date) to export from.

Thanks,

I would find it very useful. Along with the readonly view, what do you think
about adding a limited search capability? Nothing fancy, just a simple
string query. Also, since log files get closed and named with a .#, could a
selection of which logfile to view be added?

The built in search capabilities of the browser do work in text area contents too.

string query. Also, since log files get closed and named with a .#, could a

That goes beyond the time I can dedicate to this today (I had an hour I did not know how to use), but if anyone wants to contribute
improvements, please do :slight_smile:

Hi Andrea,

Indeed another very useful add on to GS!

Concerning geoserver log file, it's no longer possible in the GS 2.0.x
series modify the output folder?
In my present GS 1.7.7. configuration the log location is declared like
<logLocation>${catalina.home}/logs/geoserver.log</logLocation> in
services.xml. Testing a similar configuration on GS 2.0.2 logging.xml file -
<location>logs/geoserver.log</location> - I verified that it doesn't work.
It's really important for us configure a log location not relative to
GEOSERVER_DATA_DIR.

Thanks!
Best regards,
Pedro Mendes

I did not even know it was possible to make such configuration.
Create a jira issue for it. For better chance to get it into the next
release, don't forget to attach a patch to fix the problem :wink:
