More on monitoring dashboards for Alfresco using SOLR, Banana and Apache Zeppelin

Using an Apache stack for indexing your logs and metrics

In the previous posts I talked about ELK stack for monitoring Alfresco. But another possibility for loading metrics or logs information, extracted by logstash, is a SOLR index server (instead of Elastic Search), which is part of Alfresco architecture by default, and in principle, it would seem more natural for indexing our Alfresco logs and metrics. Besides, there exists some ports for Kibana in SOLR, such Banana or Silk, that may be deployed in our SOLR dedicated instance. Basically, you need the following steps:


  • Having a SOLR 6.x instance installed (
  • Create a logstash collection in SOLR for saving extracted logs and metrics ($SOLR_HOME/bin/solr create -c logstash -d server/solr/configsets/data_driven_schema_configs/)
  • Install logstash-output-solr_http plugin for Logstash ($LS_HOME/bin/logstash-plugin install logstash-output-solr_http) as described in the following post, and configure solr_url parameter in output section for logstash.conf
  • Clone Banana project via git (git clone
  • Deploy (copy) Banana src folder to $SOLR_HOME/server/solr-webapp/webapp/ (you may also compile dist folder via npm install && bower install && grunt build - then copy dist folder instead src).
  • Create a collection in SOLR for banana dashboards in SOLR ($SOLR_HOME/bin/solr create -c banana-int).

When starting your logstash process, you may check the corresponding info in SOLR query console for logstash collection. This is part of SOLR administration console which is a nice tool for inspecting and managing collection config or doing search queries.

Finally, you may configure a banana dashboard for visualizing some metrics events:


Finally, if you are working with Apache ecosystem, these SOLR collections may also be consumed from Apache Zeppelin via SQL. This topic was covered in past Beecon 2017 apropos SOLR features. For this, you need to install a SOLR interpreter for Apache Zeppelin (./bin/ --name zeppelin-solr --artifact com.lucidworks.zeppelin:zeppelin-solr:0.0.1-beta2) and to create a new interpreter for SOLR with the corresponding Zookeeper endpoint (solr.zkHost). Once the interpreter is available, you can configure a notebook and use some SQL and SOLR queries.
