Filebeat Pre-requisite & CPU , memory utilization

[priti (priti bhangale)]

Hi,

I have some questions regarding filebeat.

1. To deploy filebeat , we need to have java on same system ?
2. How much memory & CPU Utilized by filebeat?
3. If there is heavy log file, memory & CPU utlization also increased ? or it cause filebeat to stop?

Thanks ,
Priti

Filebeat is developed in Go language and there is no dependency of java to deploy it either by source code or by rpm.

@priti

2. How much memory & CPU Utilized by filebeat?

As Filebeat is very lightweight process, so there is no such minimum hardware requirement of filebeat is there as per elastic.co.

But I gathered few information just before and after installation of filebeat and I found it takes
Memory : approx 1810 kB
CPU usage : very very little.

To get more info regarding CPU or Memory usage you can use "vmstat", "iostat", "/proc/meminfo" before and after service start or installation of filebeat

3. If there is heavy log file, memory & CPU utlization also increased ? or it cause filebeat to stop?

Filebeat uses back-pressure protocol to handle the heavy load of logs. To handle this Filebeat spooler and harvester will use more memory and cpu . So system utilization will be increased accordingly. But it totally use case specific.

what is the CPU and Memory utilization by filebeat agent on Production server running log analyses on 30-50 application ?
