high availability SOLR

Q: Why is monitoring and alerting important to Solr health?

Performance: Monitoring and alerting can help ensure that Solr is performing optimally. By tracking metrics such as response time, query throughput, and indexing speed, administrators can identify performance bottlenecks and take action to optimize the system. Availability: Solr is often used in high-traffic, mission-critical applications. Monitoring and alerting can help ensure that Solr is always available and accessible to users. By monitoring metrics such as uptime, network latency, and request errors, administrators can quickly identify and resolve any issues that may be impacting availability. Capacity Planning: Monitoring and alerting can help administrators plan for future growth and capacity requirements. By tracking metrics such as index size, query volume, and storage utilization, administrators can identify when the system is nearing capacity and take action to add additional resources or optimize the system. Security: Monitoring and alerting can help detect and respond to security threats. By tracking metrics such as login attempts, authentication failures, and unusual user activity, administrators can quickly identify potential security breaches and take action to mitigate the risk.

With SearchStax Managed Search, getting high availability Solr is easy.

SearchStax offers highly available Solr deployments that are robust and scalable — ensuring maximum uptime and minimal downtime for your mission-critical applications.

SearchStax is trusted and proven in the largest, most demanding Solr environments

With over fifteen years of hands-on experience hosting hundreds of SolrCloud deployments, SearchStax has proven expertise configuring and managing high availability Solr.

Our implementations range from simple out-of-the box implementations to enterprise mission-critical applications where high availability, performance, failover, disaster recovery and security are critical business requirements

High availability Solr has significant value for organizations who rely on Solr to run their business

Increased Uptime

High availability Solr ensures that search is available and operation even in the event of hardware or software failures

Improved Reliability

High availability Solr eliminates the single points of failure and reduces the risk of data loss and system downtime

Better Scalability

High availability Solr allows organizations to scale horizontally to improve performance or meet spikes in traffic or demand

Enhanced Disaster Recovery

By adding disaster recovery, organizations can quickly recover from natural disasters, cyber attacks or human errors

How does SearchStax achieve high availability Solr?

SolrCloud deployments are built around clusters of virtual machines or nodes. This means that multiple copies of replicas are distributed across the Solr cluster.

SearchStax achieves high availability by deploying a Solr cluster consisting of:

Solr monitoring and alerting is an important component for maintaining high availability Solr. Active monitoring allows for early detection of any performance issues and failures, and using alerts, the appropriate team members are notified so timely corrective action can be taken.

Many organizations want to minimize any possible downtimes for the Solr deployment and achieve this by adding a disaster recovery option to their implementation.

Organizations can achieve near realtime replication of Solr deployments with Cross Data Center Replication (CDCR)

For applications with greater availability requirements, we use Cross Data Center Replication or CDCR to achieve near instantaneous synchronization across cloud regions. With CDCR, two or more Solr clusters in separate cloud regions are continuously synchronized.

Learn more about CDCR and see how one of our customers used CDCR to achieve near 100% uptime with SearchStax Cloud.

What are 4 critical metrics for Solr health?

Monitoring these 4 metrics are critical to Solr health:

JVM Heap Memory
System Load Average
Disk Space
Errors of all kinds

Learn more in the 4 Critical Metrics blog post.

What alerts are the most useful for monitoring Solr performance?

Apache ZooKeeper integration for cluster coordination and configuration.

When used with SolrCloud, ZooKeeper tracks each node of the cluster and the state of each core on each node. In this mode, configuration files are stored in ZooKeeper and not on the file system of each node

How long does SearchStax retain Solr monitoring data?

The retention period for Solr monitoring data varies depending on the Support Plan:

Silver – data is retained for 24 hours
Gold, Platinum and Platinum Plus – data is retained for 30 to 90 days depending on the contract
