So whatever the details comes behind ** - Customer_Entry :::**, I will be able to extract it using XML Plugin Filter (will be stored similar to multi-line codec). My Customized pattern which is stored inside Pattern_dir, ABC ( - Customer_Entry :::) So Even though I am using Multiple Logstash Files, and Multiple GROK Patterns, All his Information could be bounded/Aggregated using his "Customer_ID" (Unique Key)ħ-04-2017 08:49:41 INFO abcinfo (ABC_RemoteONUS_Processor.java52) - Customer_Entry ::: "D:\elk\logstash-5.2.1\vendor\bundle\jruby\1.9\gems\logstash-patterns-core-4.0.2\patterns" To track the The Individual Customer Activities, I am using "Customer_ID" as a unique key. I am Using customized GROK Patterns and logstash XML filter plugin to extract the data which would be sufficient to track. Since it is a Billing Summary log, Customer Information will be recorded in no particular order. To be Precise, I am handling a log file which has almost millions of records. Hs.message = "Waiting for rollout to finish : replicas hasn't finished updating. ![]() ![]() ![]() Hs.message = "Waiting for rollout to finish : observed sidecarSet generation less then desired generation" # Share log directory with app container via volumeMount # sidecarSet is effective for the whole cluster by default, you can specify the scope of the effect through the namespace field # Pod labels that need to be injected into the sidecar container There is a lot of documentation in the community to install EFK, this article is mainly deployed by way of Helm, refer to Elastic Helm Charts.įirst of all, K8S cluster needs StorageClass for ElasticSearch PVC, this article uses the already created alibabacloud-cnfs-nas, as follows: Upgrade Sidecar Container Independently: No rebuilding Pod, upgrade Sidecar container alone, no feeling to business service.ĮFK + SidecarSet(FileBeat) Practice Install EFK (ElasticSearch, Kibana) .Automatic Injection Of Sidecar Container: Decoupling sidecar container from business Pod configuration, simplifying business development usage cost and learning cost.For details, please refer to SidecarSet Document SidecarSet is an abstract concept for sidecar container management in OpenKruise, responsible for injecting and upgrading sidecar containers in k8s cluster, and is one of the core workloads of OpenKruise. Sidecar container upgrade will lead to business Pod rebuild, and since Sidecar containers are generally the responsibility of independent middleware teams, there will be great business-side resistance if upgraded.Ī Powerful Tool for Sidecar Container Management .operation and maintenance, proxy) multiple sidecar containers, increasing the complexity of Pod configuration and the learning cost of business developers. But there are also some disadvantages, as follows: log collection, traffic proxy).Īdvantage: decoupling the auxiliary capacity from the business container, realizing independent release and capacity reuse. Pod Sidecar Model: By defining specialized containers in Pods to perform the auxiliary work required by business containers (e.g. EFK Architecture ĮFK (ElasticSearch, FileBeat, Kibana) is a very popular and widely used log collection solution in the community, architecture as follows:Īs shown above, the FileBeat container is deployed in Sidecar mode in the same Pod as the business app container, and the logs are collected and uploaded to ElasticSearch by means of a shared volume, configuration as follows: ![]() The Sidecar approach deploys a separate logging agent for each POD, which is relatively more resource intensive, but more flexible and multi-tenant isolated, and is recommended for large K8S clusters or clusters serving multiple business parties as PAAS platforms. Best Practice for Managing Log Collection Sidecar Containers Kubernetes Container Log Collection Īs an indispensable part of any system, K8S Official Documentation also introduces various forms of log collection, summarizing the following three main types: Native approach, DaemonSet approach and Sidecar approach.Īll three approaches have advantages and disadvantages, and none of them can perfectly solve 100% of the problems, so they have to be fitted according to the scenarios.
