However if you install an intermeiate buffer for example Kafka then the agents will write logs much faster due to the fact that Kafka does not do any processing. And then you can transfer all the logs from Kafka to Elasticsearch using a separate vectorthat is a separate Vector instanceand then conveniently view them Scheme of how the streaming topology for collecting logs works . In the rest of the report we will consider Vector as an agent for collecting logs from cluster nodes. Vector in Kubernetes Now lets figure out how Vector works in Kubernetes. First lets look at the sub below Vector containers in Kubernetes after deployment in DaemonSet format.
Send their logs to syslog such
The diagram may seem overly complicate but there is a reason for that. In this pod we have three containers The first one uses Vector . Its main purpose is to collect logs. The second container is Reloader . Users of our platform have the opportunity to describe Namibia WhatsApp Number List their own log collection pipelines. A special operator takes userspecifie data and creates a configmap for Vector. The Reloaders job is to check that the config is correct and if so to reload the Vector. The third container is Kube RBAC proxy . This is important because Vector displays various metrics about the logs it collects.
Service logs on nodes Additionally
This information may be sensitive so it is important to protect it with proper authorization. Vector is deploye as a its agents must be on all nodes of the Kubernetes clustevolumes name name v name true In addition additional directories nee to be connecte to Vector so that Armenia Phone Number List it can collect logs varlog which also stores pod logs mntvectordata a directory on the host for storing checkpoints as well as for storing a buffer. Every time Vector sends a log line it writes a checkpoint to avoid duplicate logs being sent to storage localtimeto get the nodes time zone.
