I have 3 solr instances with zookeeper
Is there a way in Solr to find out the number of search query made to my solr instances? like per day/week/month wise?
Solr doesn't allow you to have statistics grouped by day/month/year.
Despite this, you can integrate your Solr cloud with third-party services like Prometheus and Grafana to store, monitor, and alert historical metrics.
Check this out: https://solr.apache.org/guide/7_3/monitoring-solr-with-prometheus-and-grafana.html
Be sure the metrics are enabled on the solr.xml config file
Install and configure your prometheus-exporter
Install and configure Prometheus and Grafana
Create the query you need on Grafana: https://grafana.com/docs/grafana/latest/panels-visualizations/query-transform-data/#query-options

Is there any way to replicate replicate file index data which is aws cloudsearch to apache solr hosted on ec2 real time.
Not really- in order to make sure that all of your original documents are indexed correctly you have to reindex them into Solr in their original form.
My current application has a Solr engine for storing large amounts of data, however I would like to have some of this data copied over to a PostGres database.
Ideally this "replication" should have a delta comparation mechanism for not missing any data coming from Solr.
I can see lots of examples for importing the data from a database into Solr (DataImportHanlder) but not the other way around, I cannot find any DataExportHandler in the Solr Documentation.
Any suggestions?
Thanks
I'm new to new Solr. I got the examples of how to index data directly from database for Solr 4.9 but still not able to find anything for Solr 6.5.
Does Solr 6.5 support database indexing? If yes, then how to achieve same.
DataImportHandler is usually the way to load data from a database into Solr. It was there in Solr 4.9 and is still there in Solr 6.5.
Specifically, Solr ships with a dih example (bin/solr start -e dih) that has a number of collection, one of them showing database indexing.
There are also third party products that can read from database and index into Solr (eg. Apache NiFi), but their levels of Solr support may vary.
I am new user to solr,I want to access and search the MYSQL database tables in java applications via solr.i am able to index my table in solr admin interface. Can anyone tell me how to connect and access MYSQL tables in java application so that i can search data fastly ? I was not able to understand tutorials whatever i found.
Solr provides client libraries in java, ruby and other languagues to help you connect to Solr and query it.
Check for the Java library Solrj to connect and query Solr.
If you are using Frameworks with your projects you might want to check for Spring data as well which will help you seamlessly query and transform Solr response.
So you will need to set up an instance of a Solr Server, SOlr will store and indexes from your database using the DataImportHandler.

Solr creates indexes using Lucene, so you have two options, you can use classes from the Lucene jar file or SolrJ to search your indexes.
OR
You can query Solr by sending http requests. I set-up a Java Web Service so you can snatch some of my code if you need to.

I have a Hbase Database that holds crawled information of wikipedia.org. My machine is at Amazon Wweb Services.
I have downloaded the Solr and I want to index the data at Hbase after that I will make search on it.
I am new to Solr and Hbase, how can I do that?
All you have to do is, run this command - sudo bin/nutch solrindex http://localhost:8983/solr/ -reindex
But before you do that please make sure your solr instance is up and running which you can verify by visiting this link http://localhost:8983/solr/ and if you can find Solr admin then your Solr instance is running.
