/_cat/indices?v等对es的查询也慢的出奇,需要1、2分钟才返回结果。 排查 top命令看了es的java进程,发现cpu一直很高,130%左右,一直没有下降过。查看es的日志,发现gc.log中几乎每秒都要触发一次GCFull GC (Allocation Failure)。内存不够用,又没有内存可回收,所以GC也不断。怪不得CPU这么高,大部分时间都用在g...
生产环境一两个请求都会将含有该分片的Es节点的负载打到15以上,导致整个集群响应偶发超时。 流量分布 负载 GC https://www.elastic.co/guide/cn/elasticsearch/guide/current/heap-sizing.html 代码语言:javascript 复制 -age1:59713408bytes,59713408total:996800K->110720K(996800K),0.2355552secs]20496770K->19901...
View GC logs to obtain detailed GC information, check whether frequent CMS GC operations or full GC operations are performed, and check whether the promotion failure is caused by insufficient space in the old generation. Log on to the Elasticsearch console and go to the Logs page of your El...
堆大小检查 默认自动根据节点角色和总内存进行配置,最小堆和最大堆要相同,避免resize导致gc暂停时间长。如果开启了bootstrap.memory_lock,可能导致resize的内存没有lock。 文件描述符检查 es需要使用很多文件描述符 Memory lock check 开启内存锁来防止内存数据交换 Maximum number of threads check es进程能够创建的最...
At this moment, the failure to release the searcher results in the lucene-merged files being not deleted. Some leafreader and fst remain in the JVM for a long time, resulting in FullGC with more and more search contexts. The user can use the following 2 APIs to view and clear these ...

关闭swap可以防止OS将内存也置换到磁盘中,根据官方文档的说法,可以防止很慢的GC: https://www.elastic.co/guide/en/elasticsearch/reference/6.7/setup-configuration-memory.html 根据文档,来配置/etc/systemd/system/elasticsearch.service.d/override.conf,设置值为: ...
副本写入失败,会向master发送一个内部请求internal:cluster/shard/failure,master接收到该请求,会根据shardId和allocationId去匹配,如果匹配关系不成立,说明主分片节点的routingTable不对,会更新clusterStats,生成StaleShard;如果匹配关系成立,说明路由信息正确,但分片无法写入,会生成FailedShard,FailedShard处理过程就是上图代...
