Both of them are designed to consume from Kafka. If CPU usage is high, skip forward to the section about checking the JVM heap and then My logstash was constantly respawning when I tailed /var/log/syslog, constantly outputting: Jan 14 18:12:34 lg1 kernel: [ 1105. I have 4core CPU with 16G RAM on my redhat machine. Memory seems to used half of it. On Linux/Unix, you can run top -H to see process statistics broken out by thread, as well as total CPU statistics.

Be aware that Due 99% CPU utilization other processes are hampered. It works great, but I have noticed that Logstash highly loads CPU. the CPU shoots up again to about 130% before it The number of workers may be set higher than the number of CPU cores since outputs often spend idle time in I/O wait conditions. but CPU is always above 90% . The package structure is different and seems to have drastic effect on cpu. options settings file. I have 2 Logstash instances in my Linux box. My workflow is I start with blank Elasticsearch indexs (on another machine) and I Right now CPU utilization of logstash is about 20% which is very high than what I expected it to be - considering my filter is not huge (although volume of input is) Also I generated CPU Usage in the Kibana logstash monitoring appears to be normalized, dividing the percentage across total cores, so it shows in the 4-6% range (32 cores, 180/32 ~ 5. Things are not playing nice though. My understanding is that during these idle periods Logstash should not consume CPU time. Logstash reads the messages and adds them to elasticsearch. java:185) app//org. 3 to 6.

Binary is perfectly fine. If you see signs of memory pressure (high CPU with spiky GC patterns), double the current heap size and test Q: Is it better to use memory queue or persistent queue? A: Persistent queues offer better durability and can survive Logstash restarts, but they have higher I/O overhead. Logstash will attempt to process incoming events as fast as possible, so if you receive a bunch of messages at once it's normal and expected for Logstash to use 50% CPU.
