Hi, we were using Solr for about 3 months without problems until a few days ago it crashed one time and we don't know why. After a restart everything was fine again but we want to be better prepared the next time this could happen. So I'd like to know what's the best way to monitor a single Solr-instance and what logging-configuration you think is useful for this kind of monitoring. Maybe there's a possibility to automatically restart Solr after it crashed + to see in detail in the logs what happend right before the crash ..?
Can you give me any hints? We're using Tomcat 6.X with Solr 4.8.X Cheers, Michael
