GitHub user sachingsachin opened a pull request:

    Solr 7121: : Solr nodes should go down based on configurable thresholds

    Code:
    SolrConfig - Adds a new config-node CoreDownThresholds (Example config in data_driven_schema_configs/conf/solrconfig.xml)
    SolrCore - Based on coreNameExpression in the above config, each core gets its own config for thresholds.
    SolrHealthMonitor* - Main logic for monitoring health of each core. Brings down a core if its stats look bad and brings the same up if the stats improve.
    ResponseTimeMonitor - Helper to SolrHealthMonitor, focussed solely on monitoring response-time of queries.
    
    Tests:
    CoreDownOnBadSelectStatsTest
    CoreDownOnHighLoadTest
    CoreDownOnLongRunningQueriesTest

    SOLR-7121: Solr nodes should go down based on configurable thresholds and not rely on resource exhaustion
    
    Code:
    SolrConfig - Adds a new config-node CoreDownThresholds (Example config in data_driven_schema_configs/conf/solrconfig.xml)
    SolrCore - Based on coreNameExpression in the above config, each core gets its own config for thresholds.
    SolrHealthMonitor - Main class for monitoring health of each core. Brings down a core if its stats look bad and brings the same up if the stats improve.
    ResponseTimeMonitor - Helper to SolrHealthMonitor, focussed solely on monitoring response-time of queries.
    
    Tests:
    CoreDownOnBadSelectStatsTest
    CoreDownOnHighLoadTest
    CoreDownOnLongRunningQueriesTest

    Refactor SolrHealthMonitor
    
    SolrHealthMonitor is broken into:
    1) SolrHealthMonitor - Interface holding public APIs
    2) SolrHealthMonitorBase - Abstract class with logic to bring cores up and down
    3) SolrHealthMonitorImpl - Has logic to get real stats like thread-count, gc-time, long-queries etc.
