Thanks for the info. I understand that the latest "replicateable" version of index may differ from the actual version of index on master/slave. But why when I use /solr/replication?command=indexversion
On master: <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">0</int> </lst> <long name="indexversion">1363263304585</long> <long name="generation">4</long> </response> And on slave: <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">1</int> </lst> <long name="indexversion">1363263600323</long> <long name="generation">5</long> </response> Why do I get higher version on slave than on master? The page https://wiki.apache.org/solr/SolrReplication states: "Get the latest replicateable index on master: http://master_host:port/solr/replication?command=indexversion"; -> ok, returns latest replicatable index version "Get version number of the index: http://host:port/solr/replication?command=indexversion"; -> for me it means that on slave I should get actual index version and not an index version appropriate for replication (it is a slave, it should not be the source of replication) Yes, it is confusing overall :) My question is: how to get actual index version on master and slave for monitoring purpose? I can use: /solr/replication?command=details On master: <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">1</int> </lst> <lst name="details"> <str name="indexSize">22.59 KB</str> <str name="indexPath">/usr/share/solr/data/index/</str> <arr name="commits"> <lst> <long name="indexVersion">1363263304585</long> <long name="generation">4</long> <arr name="filelist"> <str>_2_Lucene41_0.pos</str> <str>_2.si</str> <str>_2_Lucene41_0.tim</str> <str>_2.fdt</str> <str>_2_Lucene41_0.doc</str> <str>_2_Lucene41_0.tip</str> <str>_2.fdx</str> <str>_2.tvx</str> <str>_2.fnm</str> <str>_2_nrm.cfe</str> <str>_2.tvd</str> <str>_2_Lucene41_0.pay</str> <str>_2_nrm.cfs</str> <str>_2.tvf</str> <str>segments_4</str> </arr> </lst> </arr> <str name="isMaster">true</str> <str name="isSlave">false</str> <long name="indexVersion">1363263304585</long> <long name="generation">4</long> <lst name="master"> <str name="confFiles">schema.xml,stopwords.txt</str> <arr name="replicateAfter"> <str>commit</str> <str>startup</str> </arr> <str name="replicationEnabled">true</str> <long name="replicatableGeneration">4</long> </lst> </lst> <str name="WARNING"> This response format is experimental.
