Installbuilder check memory and space3/14/2023 Lots of delta imports also means lots of commits. If in the logs you read anything about overlapping ondecksearchers this is definitely an issue for you. If you have a master-slave setup, check to see if the slave is backing up certain configuration files, like schema.xml or solrconfig.xml.ĭepending on how many records are imported per delta, you could have commits overlapping each other, which will affect resource usage on your box. Basically you'll want to navigate to solr startup script to disable Solr's log backups and then replace that with a solution of your own. For information on how to deal with Solr's love of logging, I'm going to refer to my self-answer at Solr 5.1: Solr is creating way too many log files. Solr after 4.10 has a nasty habit of generating large numbers of log files, which can cause disk space issues, especially with how often you import. Since the logs are generated on the server, check to see how many of them exist. If there's a very, very large number, you should schedule a time during low usage to run optimize to get rid of them.Īlso be aware that Solr seems to have a tendency of filling up as much of the given heap space as it can. In fact, if you go to :/solr/#/, you should be able to see how many deleted docs are in your index. I also wonder if you're ending up with a lot of old, deleted files due to your numerous delta imports that are lying around until Solr automatically deletes them. For disk space, I wouldn't be surprised if it's the log files behind that. To me, that you can "sort of" resolve the problem by restarting Solr screams "query and import obnoxiousness" for memory. It may be something else on the box is the culprit for at least some of the resource usage. The memory and system elements will be most useful to you. It does contain faceting (field, queries), sorting, grouping, … But I doesn’t really affect the various metrics of heap and gc count.įirst, visit ://admin/system and check to see how many resources Solr is actually using. With the monitoring in place I tested the most common queries.
