Hi, Sematext's monitoring agent with a ZooKeeper integration is open-source: https://github.com/sematext/sematext-agent-java The ZK integration is at https://github.com/sematext/sematext-agent-integrations/tree/master/zookeeper (Solr and SolrCloud integrations are in the same repo) If you can't

Re: jetty access logs for monitoring

Hi, I think Logagent has support for Solr logs. Aha, yes, it does: https://github.com/sematext/logagent-js/blob/master/patterns.yml (search for Solr). But if you are looking for Solr metrics monitoring, see Solr monitoring

Re: Disadvantages of having many cores

Hi, Core per day is not too bad. I assume you'll want to keep 7 days or maybe 30 or 60 or 180 days worth of logs. That won't result in too many cores, given adequate hardware. Otis -- Monitoring - Log Management - Alerting - Anomaly Detection Solr & Elasticsearch Consulting Support Training -

Poll: Master-Slave or SolrCloud?

Hi, I'm really really surprised here. Back in 2013 we did a poll to see how people were running Master-Slave (4.x back then) and SolrCloud was a bit more popular than Master-Slave: https://sematext.com/blog/2013/02/25/poll-solr-cloud-or-not/ Here is a fresh new poll with pretty much the same

Hi, It's simply expensive. You are rewriting your whole index. Why are you running optimize? Are you seeing performance problems you are trying to fix with optimize? Otis -- Monitoring - Log Management - Alerting - Anomaly Detection Solr & Elasticsearch Consulting Support Training -

Hi Matthew, I'm guessing it's the EBS. With EBS we've seen: * cpu.system going up in some kernels * low read/write speeds and maxed out IO at times Otis -- Monitoring - Log Management - Alerting - Anomaly Detection Solr & Elasticsearch Consulting Support Training - http://sematext.com/ On

Re: Reset JMX counters for monitoring without restarting

Hi Jeff, With info that Solr provides in JMX you have to keep track of things yourself, do subtractions and counting yourself. If you don't feel like reinventing that, see https://sematext.com/spm/integrations/solr-monitoring/ Otis -- Monitoring - Log Management - Alerting - Anomaly Detection

Re: High Cpu sys usage

Hi, I looked at those metrics outputs, but nothing jumps out at me as problematic. How full are your JVM heap memory pools? If you are using SPM to monitor your Solr/Tomcat/Jetty/... look for a chart that looks like this: https://apps.sematext.com/spm-reports/s/zB3JcdZyRn If some of these

Re: Solr memory usage

Hi Steve, Fluctuation is OK. 100% utilization for more than a moment is not :) Not sure what tool(s) you use for monitoring your Solr servers, but look under "JVM Pool Utilization" in SPM if you're using SPM. Or this live demo of a Solr system: * click on https://apps.sematext.com/demo to get
