This article mainly introduces "what to do with CPU100% caused by too much redis total_connections_received". In daily operation, I believe that many people have doubts about what to do with CPU100% caused by too much redis total_connections_received. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubt that "too much redis total_connections_received leads to CPU100%". Next, please follow the editor to study!

During the stress test, it was found that the throughput had been around 3000. During the monitoring of redis, it was found that the total_connections_received was particularly high (up to 70W connections per minute), which directly caused the CPU of the redis server to reach 100%. Although the connection pool was configured, the connection pool did not take effect. The inspection found that when using Spring Boot, the JedisConnectionFactory was created on its own, but the creation was not standardized, so the connection pool did not take effect.

JedisShardInfo shardInfo = new JedisShardInfo ("http://" + connectionFactory.getHostName () +": "+ connectionFactory.getPort ()); shardInfo.setPassword (connectionFactory.getPassword ()); shardInfo.setSoTimeout (connectionFactory.getTimeout ()); connectionFactory.setShardInfo (shardInfo)

The JedisShardInfo here does not need to manually write the afterPropertiesSet method that directly uses JedisConnectionFactory.

ConnectionFactory.afterPropertiesSet (); at this point, the study of "what to do with CPU100% caused by too much redis total_connections_received" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
