Managing and Monitoring Apache Solr
Apache Solr is an open source full text search platform for the enterprise. It includes real time indexing, dynamic clustering and rich document (e.g. Word, PDF) handling. Solr is designed for scalability and fault tolerance.
The Instana agent will automatically detect the presence of Apache Solr and install the sensor for it along with the sensors for the JVM and process it is running on. Additionally sensors for the OS and if running inside a container the sensor for Docker are also installed. This level of automation reduces the effort required by the operations team to set up and maintain the monitoring. Rapidly start sending metric data with the minimum of work required.
Typical metrics that are tracked include:
- Request rate
- Cache hit ratio
See the documentation for a complete list.
Instana will track the metrics and health signatures of Apache ActiveMQ with 1-second granularity and raise an Event within 3 seconds if they go out of bounds. The use of Machine Learning applied to pattern detection together with a curated knowledge base acting on the collected raw metrics, is what makes Instana different to other monitoring solutions. The intelligence is built in, there is no need to spend time creating and maintaining numerous health rules to trigger alerts.
Instana will detect configuration changes and tack them on the timeline. See how changes to configuration affect application performance.
