To change the ESE index in Fluent Bit

To change the ESE index in Fluent Bit, you can follow these steps:

  1. Open the Fluent Bit configuration file (typically located at /etc/td-agent-bit/td-agent-bit.conf or /etc/fluent-bit/fluent-bit.conf, depending on your installation).

  2. Locate the output section for the ESE output plugin. It should look something like this:

    [OUTPUT]
    Name        ese
    Match       ese.*
    Index       fluent-bit
    Database    /var/lib/td-agent-bit/ese.db
    Interval_Sec 10

  3. Change the value of the Index parameter to the desired name of your ESE index. For example, if you want to create an index named "myindex", you would change the configuration to:

    [OUTPUT]
    Name        ese
    Match       ese.*
    Index       myindex
    Database    /var/lib/td-agent-bit/ese.db
    Interval_Sec 10

  4. Save the configuration file and restart the Fluent Bit service to apply the changes.

    On Linux, you can restart Fluent Bit using the following command:

    sudo systemctl restart td-agent-bit

    On Windows, you can restart the Fluent Bit service from the Services app in the Control Panel.

After following these steps, Fluent Bit will use the new ESE index name that you specified in the configuration file.

To switch to a specific tag in a Git repository

To switch to a specific tag in a Git repository, you can use the git checkout or git switch command. Here's how you can do it: 1. List Available Tags First, you may want to see a list of all available tags in the repository: git tag 2. Checkout a Specific Tag Once you know the tag you want to switch to, you can use either git checkout or git switch (if you're using a newer version of Git, which recommends git switch for checking out branches). Using git checkout : git checkout <tag- name > Using git switch (recommended for newer versions of Git): git switch -- detach <tag- name > The --detach flag is necessary because tags are not branches; they are just pointers to specific commits. Using --detach makes your HEAD point to the tag without modifying any branch. 3. Verify the Checkout After switching to the tag, verify that you're on the correct commit: git status This will show the tag you're currently on (you'll see somethi...

How to checkout branch of remote git, 깃 리모트 브랜치 체크아웃

To check out a branch from a remote Git repository, you can follow these steps: 1. Fetch the remote branches First, ensure that your local repository is aware of the remote branches by using git fetch . This updates your local references to the remote branches. git fetch origin 2. Check out the remote branch Once the remote branches are fetched, you can check out the desired branch using git checkout -b and specifying the remote branch. Command: git checkout -b < local -branch- name > origin/<remote-branch- name > Explanation: <local-branch-name> : The name you want to give to your local branch. origin/<remote-branch-name> : Refers to the branch on the remote called origin (which is the default name for the main remote repository) and the branch you want to check out. Example: If the remote branch is called feature-branch and you want to create a local branch with the same name, you would run: git checkout -b feature -branch origin / feature -...

Using the MinIO API via curl

Using the MinIO API via curl is straightforward, as MinIO is compatible with Amazon S3 API, so most commands follow a similar syntax. Here’s a guide on how to use curl with the MinIO API for some common operations like uploading, downloading, and managing objects. Prerequisites Access Key and Secret Key : Obtain your MinIO Access Key and Secret Key. MinIO Endpoint : Know your MinIO server endpoint, e.g., http://localhost:9000 . Bucket : You may need an existing bucket name, or create a new one using the commands below. Authentication Header For requests to work with MinIO, you need to include authentication in the headers. MinIO uses AWS Signature Version 4 for signing requests. Common Examples 1. List Buckets To list all buckets in your MinIO account, use: curl -X GET \ - -url "http://localhost:9000/" \ - H "Authorization: AWS <AccessKey>:<Signature>" 2. Create a Bucket To create a new bucket, use: curl -X PUT \ - -url "htt...

리눅스의 부팅과정 (프로세스, 서비스 관리)

보통 사용되지 않는 서비스나 사용 빈도가 적은 프로세스의 경우 stop 시켜두는 것이 시스템 사용 상의 이점이 있다. 자신에게 필요 없는 프로세스를 정지 한다거나 nice 값을 조정하여 실행 시에 프로세스의 우선순위를 변화시킬 수 있다. 이렇게 시스템 상황에 따라 적절히 서비스들을 관리하려면 현재 자신의 시스템의 여러가지 상황을 알아야 하는데, 이런 경우 프로세스 및 실시간 시스템 상황을 보는 명령어인 top 을 사용할 수 있다.  top [-][d delay][q][c][S][s][i][n][b] -d delay : delay 의 시간이 경과하면 현재 스크린을 갱신한다. -q : 이 옵션을 사용하면 스크린을 계속 갱신한다. -c : command list 전체를 보여준다. 즉 욥선을 사용한 것까지 모두 보여준다. -i : idle 상태와 zombie 프로세스는 무시한다.   * 이 외의 옵션은 man 파일을 참고 top 실행 화면 1.

Joining an additional control plane node to an existing Kubernetes cluster

Joining an additional control plane node to an existing Kubernetes cluster involves specific steps to ensure proper synchronization between the control plane components. Below is the detailed process: 1. Pre-Requisites Ensure the following on the new control plane node: Same Kubernetes Version : The new node must have the same Kubernetes version installed as the existing control plane. kubeadm version Kubeadm, Kubelet, and Kubectl Installed : Ensure these tools are installed and configured. Network Configuration : The new control plane must have network connectivity to the existing control plane nodes. 2. Retrieve the Join Command On an existing control plane node, generate the kubeadm join command with the --control-plane flag: kubeadm token create -- print -join-command You will get output similar to: kubeadm join <control-plane-endpoint> : 6443 --token <token> \ --discovery-token- ca -cert-hash sha256 : <hash> \ --control-plane 3. ...

CDPEvents in puppeteer

In Puppeteer , CDPEvents refers to events emitted by the Chrome DevTools Protocol (CDP) . Puppeteer leverages CDP to interact with and control a Chromium-based browser. CDP provides detailed, low-level access to browser internals, such as network traffic, console logs, page lifecycle events, and more. You can listen to these CDP events through Puppeteer’s API to monitor or intercept browser activity. How to Listen for CDP Events in Puppeteer Enable the Required CDP Domain: Some events require enabling a particular domain (e.g., 'Network' , 'Page' , 'Runtime' ). Use page._client() to Access the CDP Session: Although it’s a bit lower-level, Puppeteer allows access to DevTools through the page._client() API. Example: Listening for Network Requests This example demonstrates how to intercept and log network requests using CDP. const puppeteer = require( 'puppeteer' ); ( async () => { const browser = await puppeteer.launch({ headless...

Avro + Grpc in python

Developing a gRPC client in Python that leverages Avro serialization involves several steps. gRPC is a high-performance RPC framework, while Apache Avro is a serialization framework used for efficient data exchange. In this example, we will show how to: Define gRPC services using Protocol Buffers ( .proto ). Serialize and deserialize data using Avro. Implement the gRPC server and client in Python. We’ll walk through the Avro-based gRPC client-server application in Python, using gRPC to transmit messages and Avro to serialize the messages. Overview of the Application Avro is used to serialize complex data structures (e.g., dictionaries) into bytes. gRPC transmits the serialized Avro bytes over the network. Python will be used to implement the gRPC client and server. Steps to Develop the gRPC + Avro Application Step 1: Install Required Dependencies Ensure you have the following dependencies installed: pip install grpcio grpcio-tools avro-python3 grpcio and ...
