    Administering and Monitoring SolrCloud Clusters Administering and Monitoring SolrCloud Clusters Presentation Transcript

    • Administering and Monitoring SolrCloud Rafał Kuć – Sematext Group, Inc. @kucrafal @sematext sematext.com
    • Ta me… Sematext consultant & engineer Solr.pl co-founder Father and husband 
    • SolrCloud Concepts Shard1 Replica Shard2 Replica Solr Server Solr Server Shard2 Shard1 Solr Server Solr Server Application
    • Local SolrCloud Cluster java -Dbootstrap_confdir=./solr/revolution/conf -Dcollection.configName=revolution -DzkRun -DnumShards=1 -jar start.jar Runs embedded ZooKeeper Bootstraps collection with 1 shards Starts Solr
    • Starting Solr Cluster No Collection No Collection -DzkHost=192.168.1.1:2181, 192.168.1.2:2181,192.168.1.3:2181 Solr Server -DzkHost=192.168.1.3:2181, 192.168.1.1:2181,192.168.1.2:2181 Solr Server No Collection No Collection -DzkHost=192.168.1.2:2181, 192.168.1.1:2181,192.168.1.3:2181 -DzkHost=192.168.1.3:2181, 192.168.1.1:2181,192.168.1.2:2181 Solr Server ZooKeeper ZooKeeper ZooKeeper Solr Server
    • Uploading Collection Configuration ./zkcli.sh -cmd upconfig -zkhost 192.168.1.1:2181 -confdir ./conf/ -confname revolution ZooKeeper Collection configuration ZooKeeper ZooKeeper Solr
    • Collections API Create Delete Reload Split Create Alias Delete Alias Shard Creation/Deletion http://wiki.apache.org/solr/SolrCloud
    • Collection Creation curl 'http://solrhost:8983/solr/admin/collections?action=CREATE &name=revolution&numShards=3&replicationFactor=4' name numShards replicationFactor maxShardsPerNode createNodeSet collection.configName
    • Collection Split Example $ curl 'http://solr1:8983/solr/admin/collections?action=CREATE& name=collection1&numShards=2&replicationFactor=1'
    • Collection Split Example $ curl 'http://localhost:8983/solr/admin/collections? action=SPLITSHARD&collection=collection1&shard=shard1'
    • Getting Deeper – CoreAdmin API curl 'http://solrhost:8983/solr/admin/cores?action=CREATE &name=newcore&collection=revolution&shard=shard2' collection shard numShards collection.configName
    • Schema – the API Reading (Solr 4.2) Fields Dynamic fields Types Copy fields Name (4.3) Version (4.3) Unique Key (4.3) Similarity (4.3) Writing (Solr 4.4) Adding new fields Adding copy fields
    • Reading Your Schema curl -XGET 'http://solrhost:8983/solr/rev/schema/fields/name' { "responseHeader" : { "status" : 0, "QTime" : 5 }, "field" : { "name" : "name", "type" : "text_general", "indexed" : true, "stored" : true } } Full reference: http://wiki.apache.org/solr/SchemaRESTAPI
    • Dynamic Schema Modifications <schemaFactory class="ManagedIndexSchemaFactory"> <bool name="mutable">true</bool> <str name="managedSchemaResourceName">managed-schema</str> </schemaFactory> curl -XPUT 'http://solrhost:8983/solr/rev/schema/fields/content' –d '{ "type" : "text", "stored" : "false", "copyFields" : ["catchAll"] }' curl -XPOST 'http://solrhost:8983/solr/rev/schema/copyFields' -d '[ { "source" : "name", "dest" : [ "text", "personal" ] } ]'
    • The Right Directory StandardDirectory SimpleFSDirectory NIOFSDirectory MMapDirectory _0.fdt _0.fdx _0.fnm _0.nvd _1.fdt _1.fdx _1.fnm _1.nvd NRTCachingDirectory RAMDirectory <directoryFactory name="DirectoryFactory" class="solr.NRTCachingDirectoryFactory" />
    • Segment Merging Level 0 a b f Level 1 c c d e g
    • Segment Merge Under Control Merge policy Merge scheduler Merge factor Merge policy configuration https://cwiki.apache.org/confluence/display/solr/IndexConfig+in+SolrConfig
    • Autocommit or Not? Automatic data flush (hard commit) Automatic index view refresh <autoCommit> <maxTime>15000</maxTime> <maxDocs>1000</maxDocs> <openSearcher>false</openSearcher> </autoCommit> <autoSoftCommit> <maxTime>1000</maxTime> </autoSoftCommit>
    • Caches Refreshed with IndexSearcher Configurable Different purposes Different implementations Solr Cache
    • Monitoring Importance
    • What to Pay Attention to?
    • Cluster State Health Shards and replica status Shard placement Failing nodes
    • Indexing Related Metrics Index throughput Document distribution I/O subsystem metrics Merging
    • Search - related Metrics Count Latency Distribution among nodes Anomalies and spikes
    • Monitoring Memory and GC Heap details Pool size Pool utilization Garbage collection count Garbage collection time
    • Monitoring OS Related Metrics CPU details Load I/O activity Network usage
    • Solr Administration Panel
    • Solr & JMX <jmx /> java -Dcom.sun.management.jmxremote –jar start.jar
    • Solr & JMX
    • SPM Index statistics Request # and latency Caches and warmup CPU JVM Memory and OS Memory Garbage collector OS related statistics
    • SPM Dashboard
    • Other Monitoring Tools Ganglia http://ganglia.sourceforge.net/ New Relic http://www.newrelic.com/ Opsview http://www.opsview.com
    • Too much is too much
    • Too hot
    • Caches
