Andrzej Bialecki commented on SOLR-13155: ------------------------------------------ This patch implements a tool for getting the current suggestions / diagnostics and/or testing the current cluster against the supplied autoscaling configuration. The tool is integrated into the SolrCLI suite, and hooked up to the {{bin/solr autoscaling}} script. One notable addition is a method in {{RedactionUtils}} for replacing collection names and node names / IPs in the output data. You can see it in action when you invoke the tool with the {{-r}} option: {code} ... { "liveNodes":[ "N_1_solr", "N_0_solr"], "violations":[ { "collection":"COLL_0", "node":"N_1_solr", "tagKey":"N_1_solr", "violation":{ "replica":{ "NRT":2, "count":2}, "delta":1.0}, "clause":{ "replica":"<2", "shard":"#ANY", "node":"#ANY", "collection":"COLL_0"}, "violatingReplicas":[ {"core_node7":{ "core":"COLL_0_shard2_replica_n3", "shard":"shard2", "collection":"COLL_0", "node_name":"N_1_solr", "type":"NRT", "leader":"true", "base_url":"http://N_1/solr", "state":"active", "force_set_state":"false", "INDEX.sizeInGB":6.426125764846802E-8}}, {"core_node6":{ "core":"COLL_0_shard1_replica_n2", "shard":"shard1", "collection":"COLL_0", "node_name":"N_1_solr", "type":"NRT", "leader":"true", "base_url":"http://N_1/solr", "state":"active", "force_set_state":"false", "INDEX.sizeInGB":6.426125764846802E-8}}]}, ... {code} TODO: hook up the tool to the Windows scripts.

Issues are Public) > Components: AutoScaling > Reporter: Andrzej Bialecki > Assignee: Andrzej Bialecki > Priority: Major > Fix For: 8.0, master (9.0) > > Attachments: SOLR-13155.patch > > > Solr already provides /autoscaling/diagnostics and /autoscaling/suggestions > endpoints. In some situations it would be very helpful to be able to run > "what if" scenarios using data about nodes and replicas taken from a > production cluster but with a different autoscaling policy than the one that > is deployed, without also worrying that the calculations would negatively > impact a production cluster's Overseer leader. > All necessary classes (including the Policy engine) are self-contained in the > SolrJ component, so it's just a matter of packaging and writing a CLI tool + > a wrapper script. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
