Hi Walter, Do you see errors in the logs when visiting the following page?
https://dspace36a.library.uaf.edu/search-statistics At least on that page I got “There was an error while generating the search statistics, please try again later.” You can also see an error message when visiting https://dspace36a.library.uaf.edu/workflow-statistics -- Sean From: dspace-tech@googlegroups.com <dspace-tech@googlegroups.com> On Behalf Of wlrutherf...@alaska.edu Sent: October 18, 2018 2:52 PM To: DSpace Technical Support <dspace-tech@googlegroups.com> Subject: Re: [dspace-tech] View Statistics links not working This is maddening and taking far longer than it should, mostly because I can't tell where the problem is located. I've setup all of the configuration variables mentioned in the manual but I'm not seeing anything in the logfiles that says what's wrong. It could be a combination of Tomcat/DSpace, httpd, solr, ... The only other similar posts I've seen here haven't had solutions. It doesn't help that I haven't see the statistics links working so I'm not quite sure even what to expect. For example: I can see https://dspace36a.library.uaf.edu/solr but that looks more like an administrator page. But I don't need to be logged in at all to see it and I'm pretty sure that's not the statistics page. If I try this instead: https://dspace36a.library.uaf.edu/statistics I get an entirely blank page. In my experience that means it's being handled (it's not returning an error) but the output is null. I can attach config files or logs but which would be most useful to help troubleshoot this problem? Thank you. Walter R.

There was something a co-worker had added to the web.xml file to force HTTPS but I don't see it now. He might've removed it and put all that in the httpd configuration. If he didn't that might be the problem - the two of them fighting.

That "messages.xml" file is not directly related to Solr. The XMLUI also looks for those files in several different locations, so if it doesn't find them in one place, it will look elsewhere. So, those log lines can likely be ignored. What you should be looking more closely at is whether any errors/warnings are occurring in the dspace.log files (or Tomcat logs) when you: (1) Access any Community/Collection/Item homepage on the site --- this should contact Solr and log a "view" of that Item (2) When you access the statistics page (that empty page may be throwing an error behind the scenes). Essentially look closely at the logs whenever you are performing tasks that should be logging "view" statistics to Solr, and also look closely in the Tomcat logs to be sure that the "/solr" webapp is deploying properly, without errors. - Tim On Tue, Oct 9, 2018 at 2:41 PM <wlruth...@alaska.edu<mailto:wlruth...@alaska.edu>> wrote: This might be the problem.

I started to say the messages.xml file exists but no, the one I've had to edit is in the i18n directory - the one in the error message doesn't exist in i18n/aspects/Versioning - the entire 'aspects' subdirectory doesn't exist at all. I could create the directories but can't populate them without knowing what should be in there. Where should it have come from? If fixing this doesn't require a scratch rebuild we might be able to quickly squash this bug. Walter R.

So, for example, if Tomcat is running on http://localhost:8080, then Solr should be accessible on something like http://localhost:8080/solr/ In other words, the only way DSpace can properly communicate with Solr (to send/query statistics) is if it's available in Tomcat. The full path to Solr in Tomcat should also be configured in your installed [dspace]/config/modules/solr-statistics.cfg: https://github.com/DSpace/DSpace/blob/dspace-5_x/dspace/config/modules/solr-statistics.cfg#L12 If DSpace is unable to find/communicate with Solr, you likely would see errors appearing in your logs. - Tim On Tue, Oct 9, 2018 at 2:04 PM <wlruth...@alaska.edu<mailto:wlruth...@alaska.edu>> wrote: Thank you Tim. I didn't notice anything in the logs that seemed to point to a problem with Solr or the statistics. I'll look again to make sure I haven't overlooked something. Also checking the troubleshooting page you linked. I'm not sure what you mean by the DSpace Solr webapp, *must* be installed into Tomcat. Are you talking about during the build it must be configured with Tomcat or that it is configured in the [dspace]/webapps/solr directory after DSpace has been built? Walter R. On Tuesday, October 9, 2018 at 10:28:53 AM UTC-8, Tim Donohue wrote: Hi Walter, I'd recommend checking your logs for any errors or warnings. We have a guide for doing so at: https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error DSpace does *require* using Solr for Statistics. However, the required "solr" webapp is provided out-of-the-box with DSpace (it is built into the [dspace]/webapps/solr/ directory), so you do not need to install Apache Solr separately. That DSpace Solr webapp *must* be installed into Tomcat (alongside your UI, either XMLUI or JSPUI) for Statistics to work properly. Any errors that are occurring with accessing or logging statistics should be logged in your dspace.log file (or, occasionally, in the Tomcat logs). In the XMLUI, blank pages usually mean something went wrong. Most of the time, you should have more information in your logs. However, if no information is found there, it's always possible that the problem is in your *theme* (XSLTs or similar). So, if you get stuck, you may also want to try temporarily switching to a default DSpace theme, to ensure your custom theme is not causing issues. If you have more information to share, or start to figure out what might be to blame, please let us know on this mailing list. Currently, though, it doesn't look like we have enough information to provide help (unless someone else on this mailing list has seen this exact same behavior before).

I have an older server running DSpace3.1 which is a "copy" of the original system. The statistics apparently haven't worked since the system moved. The 2nd system is running DSpace5.5. On both systems there is a "View Usage Statistics" link on the Home page but following the link gives a valid, live page but with no numbers. The Search and Workflow statistic links give identical error messages on both systems. I have gone through the manual and tried enabling all of the configuration parameters mentioned but with no luck. I even tried a few which didn't at first seem necessary but couldn't hurt. Still nothing. The manual says that DSpace uses Apache Solr and there is no need to download any separate software. But something isn't working. Do I really need to install and run Apache Solr? What I'm I misconfiguring? Does this look familiar to anyone?
