DSpace
...
DSpace 1.6 and newer versions uses the Apache SOLR application underlying the statistics. SOLR enables performant searching and adding to vast amounts of (usage) data.
Unlike previous versions, enabling statistics in DSpace does not require additional installation or customization. All the necessary software is included.

The DSpace Statistics Implementation is a Client/Server architecture based on Solr for collecting usage events in the JSPUI and XMLUI user interface applications of DSpace. Solr runs as a separate webapplication and an instance of Apache Http Client is utilized to allow parallel requests to log statistics events into this Solr instance.
Configuration settings for Statistics
In the {dspace.dir}/config/modules/solr-statistics.cfg file review the following fields to make sure they are uncommented:
Property: | solr.log.server | server | ||||||
Example Value: | solr.log. server = http://127.0.0.1/solr/statistics | |||||||
Informational Note: | Is used by the SolrLogger Client class to connect to the Solr server over http and perform updates and queries. In most cases, this can (and should) be set to localhost (or 127.0.0.1).
Assuming you get an HTTP 200 OK response, then you should set | |||||||
Property: | solr. spiderips.urls | |||||||
Example Value: | solr. spiderips.urls =

Property:

Example Value:
solr.resolver.timeout = 200
Informational Note:

]]></ac:plain-text-body></ac:structured-macro>
Property:
statistics.item.authorization.admin
Example Value:
statistics.item.authorization.admin = true
Informational Note:
When set to true, only general administrators, collection and community administrators are able to access the statistics from the web user interface. As a result, the links to access statistics are hidden for non logged-in admin users. Setting this property to "false" will display the links to access statistics to anyone, making them publicly available.
Property:
solr.statistics.logBots
Example Value:
solr.statistics.logBots = true
Informational Note:
When this property is set to false, and IP is detected as a spider, the event is not logged.
When this property is set to true, the event will be logged with the "isBot" field set to true.
(see solr.statistics.query.filter.* for query filter options)
Property:
solr.statistics.query.filter.spiderIp
Example Value:
solr.statistics.query.filter.spiderIp = false
Informational Note:
If true, statistics queries will filter out spider IPs -- use with caution, as this often results in extremely long query strings.
Property:
solr.statistics.query.filter.isBot
Example Value:
solr.statistics.query.filter.isBot = true
Informational Note:
If true, statistics queries will filter out events flagged with the "isBot" field. This is the recommended method of filtering spiders from statistics.

Statistics differences between DSpace 1.7.x and 1.8.0
Displayed file statistics bundle configurable
In DSpace 1.6.x & 1.7.x the file download statistics were generated without regard to the bundle in which the file was located. In DSpace 1.8.0 it is possible to configure the bundles for which the file statistics are to be shown by using the query.filter.bundles property. If required the old file statistics can also be upgraded to include the bundle name so that the old file statistics are fixed.
Warning | ||
---|---|---|
| ||
Applying this change will involve dumping all the old file statistics into a file and re uploading these. Therefore it is wise to create a backup of the {dspace.dir}/solr/statistics/data directory. It is best to create this backup when the Tomcat/Jetty/Resin server program isn't running. |
When a backup has been made start the Tomcat/Jetty/Resin server program.
The update script has one optional command which will if given not only update the broken file statistics but also delete file statistics for files that where removed from the system (if this option isn't active these statistics will receive the "BITSTREAM_DELETED" bundle name).

...
In DSpace 1.6.x, each solr event was committed to the solr server individually. For high load DSpace installations, this would result in a huge load of small solr commits resulting in a very high load on the solr server.
This has been resolved in dspace 1.7 by only committing usage events to the solr server every 15 minutes. This will result in a delay of the storage of a usage event of maximum 15 minutes. If required, this value can be altered by changing the maxTime property in the
