1. Solr Monitor
In Data Collection, we introduced the common data sources. As a monitor framework, Open-Falcon can collect the monitor index data of any system as long as they are converted to the standard format of Open-Falcon.
The data collection of solr can be done through the script solr_monitor.
1.1. Working Principle
Solr-monitor is a cron that runs the script solr_monitor.py every minute. It mainly collects the information of solr instance memory, cache hit and etc. Next it encapsulates them in the format that is suitable for Open-Falcon and post them to the local falcon-agent.
The script can be deployed in each Solr instance with a cron that collects the data reguarly. Therefore, Solr instance and cron matches one-to-one.
If a server has multiple solr instances, user can change the servers property in solr_monitor.py to add the address of Solr instance to realize the local one-to-many data collection.
