11/12/2022 0 Comments Filebeats cleanup data![]() The maximum possible memory occupied by filebeat is max_message_bytes * = 40G. max_message_bytes is the size of a single message.In versions before 6.0, this parameter is spool size, which can be configured at startup through the command line The default value of events message queue is 4096. From the perspective of configuration, there are two main indicators affecting filebeat memory usage: Note that in the above configuration, only the number of cpu cores is limited, and there is no special limit on the utilization of memory. It is recommended to manually set it to 1 max_procs, which limits the number of filebeat processes, is actually the number of cores.multiline, multi line configuration, when the log file does not meet the specification and a large number of matching pattern s, it will cause memory leakage.This is wrong, this is wrong, this is wrong!!! The reasonable way is to analyze specific problems and make customized configurations for different scenarios. It is this undifferentiated simple configuration that causes problems. We use a unified simple configuration to monitor many hosts. Here, I mainly describe the problems I encountered on filebeat 6.0. No matter what version (the latest version 6.5 has not been observed for the time being), it takes up too much memory in different scenarios and configurations. Unfortunately, the problem of memory leakage has not been completely solved since the birth of filebeat. However, if there are some unexpected situations, such as occupying a large amount of memory, the operation and maintenance team must give priority to ensuring the resources of the core business and kill the filebeat process. When this consumption can be limited to an acceptable range, I don't think anyone will restrict you to use filebeat in the production environment. When filebeat runs, it will certainly consume cpu, memory, network and other resources. According to the official recommendation, filebeat is not recommended to collect data on NFS (network shared disk). It is generally installed in the same place as the program generating the collected files (mainly logs). Here we will discuss the problem of memory leakage in detailįilebeat is one of the core components of beats Suite (another core is metricbeat). There may be many aspects that affect the performance of the host, such as CPU occupancy, network throughput occupancy, disk IO, memory, etc. Because the stable operation of the business is the core KPI, and other data generated by operation and maintenance is always a lower priority. However, since beats need to be installed outside the ELK cluster, on the host, its impact on the performance of the host often becomes the key to consider whether it can be used, rather than what functions it provides. Beats is a group of lightweight software, which provides us with a simple and fast way to collect and enrich more data in real time to support our analysis. If set to true, replace dots in labels with _.īut I think I am just going to use CLI flags to mount the docker socket as volumes.ELK was renamed elastic stack after it added beats suite after releasing 5.0. (Optional) Time of inactivity to consider we can clean and forget metadata for a container, 60s by default. It defaults to 4 to match /var/lib/docker/containers//*.log (Optional) Index in the source path split by / to look for container ID. This allows to match directories names that have the first 12 characters of the container ID. (Optional) Match container short ID from a log path present in the field. (Optional) Match container ID from a log path present in the field. If the process is running in Docker then the event will be enriched. (Optional) A list of fields that contain process IDs. (Optional) A list of fields to match a container ID, at least one of them should hold a container ID to get the event enriched. (Optional) SSL configuration to use when connecting to the Docker socket. It uses unix:///var/run/docker.sock by default. (Optional) Docker socket (UNIX or TCP socket).
