Logstash is open-source and free. At some point Sematext contributed Solr connector/output to Logstash. Here are some numbers about Logstash (and rsyslog, which is also an option, though it doesn't have Solr output): http://blog.sematext.com/2015/05/18/tuning-elasticsearch-indexing-pipeline-for-logs/
If you are new to Logstash, this is a good one: http://blog.sematext.com/2013/12/19/getting-started-with-logstash/ Note: Solr was mentioned as the destination for logs here, but it's not the only option. You can send your logs to other systems and services, including off-site ones, those that also archive your old logs for audit or other purposes, have more than just basic log search functionality, etc. HTH Otis -- Monitoring * Alerting * Anomaly Detection * Centralized Log Management Solr & Elasticsearch Support * http://sematext.com/ On Mon, Jun 1, 2015 at 4:47 PM, Vishal Swaroop <vishal....@gmail.com> wrote: > Thanks Rajesh... just trying to figure out if *logstash *is opensource and > free ? > > On Mon, Jun 1, 2015 at 2:13 PM, Rajesh Hazari <rajeshhaz...@gmail.com> > wrote: > > > Logging : > > > > Just use logstash to a parse your logs for all collection and logstash > > forwarder and lumberjack at your solr replicas in your solr cloud to send > > the log events to you central logstash server and send it to back to solr > > (either the same or different instance) to a different collection. > > > > The default log4j.properties that comes with solr dist can log core name > > with each query log. > > > > Security: > > suggest you to go through this wiki > > https://wiki.apache.org/solr/SolrSecurity > > > > *Thanks,* > > *Rajesh,* > > *(mobile) : 8328789519.* > > > > On Mon, Jun 1, 2015 at 11:20 AM, Vishal Swaroop <vishal....@gmail.com> > > wrote: > > > > > It will be great if you can provide your valuable inputs on strategy > for > > > logging & security... > > > > > > > > > Thanks a lot in advance... > > > > > > > > > > > > Logging : > > > > > > - Is there a way to implement logging for each cores separately. > > > > > > - What will be the best strategy to log every query details (like > source > > > IP, search query, etc.) at some point we will need monthly reports for > > > analysis. > > > > > > > > > > > > Securing SOLR : > > > > > > - We need to implement SOLR security from client as well as server > > side... > > > requests will be performed via web app as well as other server side > apps > > > e.g. curl... > > > > > > Please suggest about the best approach we can follow... link to any > > > documentation will also help. > > > > > > > > > > > > Environment : SOLR 4.7 configured on Tomcat 7 (Linux) > > > > > >
