stapeldiagram från Kibana med antalet besök på trainfo.eu under några dagar

Utan externa statistiktjänster som kräver cookies (trainfo.eu är nog i en väldigt liten minoritet som inte har cookies) kan man räkna besökare från webserverloggarna (anonymiserade). Flest besökare på förmiddagen och kvällen.

Inga större överraskningar […]

Introduction to the ELK Stack The ELK Stack (Elasticsearch, Logstash, and Kibana) is a powerful suite for managing and analyzing logs and other structured/unstructured data. By integrating Beats, the stack supports lightweight data shippers for log and metric collection. #### Elasticsearch * A distributed, RESTful search and analytics engine. * Stores, searches, and analyzes massive volumes of data quickly and in near real-time. #### Logstash * A data processing pipeline that ingests data from multiple sources, transforms it, and sends it to Elasticsearch. #### Kibana * A visualization tool that provides insights into data stored in Elasticsearch. * Enables users to create charts, graphs, and dashboards for monitoring and analytics. #### Beats * Lightweight data shippers that send data from edge machines to Logstash or Elasticsearch. * Includes Filebeat for log files, Metricbeat for metrics, and others. #### Use Cases * Log and event data analysis. * Real-time application monitoring. * Security and compliance reporting. ### 2. Pre-requisites #### System Requirements * Minimum requirements for a single node: * **CPU:** 4 cores * **RAM:** 16GB * **Disk Space:** 50GB (varies based on retention needs) * For multi-node clusters: * Dedicated roles (Master, Data, and Ingest) recommended. * Nodes should reside on a private network. #### Dependencies * **Java:** Elasticsearch and Logstash require Java 11 or later. * **OpenSSL:** For enabling TLS encryption. * **Firewall Rules:** Ensure ports 9200, 9300 (Elasticsearch), 5044 (Logstash), and 5601 (Kibana) are open as needed. #### Security Considerations * Always enable TLS encryption for inter-node communication. * Use authentication and authorization mechanisms provided by Elasticsearch. * Restrict access to management tools such as Kibana using firewalls and authentication. ### 3. Installation of ELK Stack #### Elasticsearch ##### Single Node Installation 1. **Download Elasticsearch:** wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-<version>-linux-x86_64.tar.gz 1. **Extract and Install:** tar -xvf elasticsearch-<version>-linux-x86_64.tar.gz cd elasticsearch-<version> 1. **Set JVM Options and Heap Size:** * Edit `config/jvm.options` to allocate appropriate heap size. * Example: -Xms8g -Xmx8g 2. **Run Elasticsearch:** ./bin/elasticsearch 1. **Test Elasticsearch:** Visit `http://localhost:9200` in your browser or use: curl -X GET "localhost:9200/" ##### Multi-node Cluster Setup 1. **Prepare Each Node:** Follow steps 1-4 above on each node. 2. **Configure Cluster Settings:** * Edit `elasticsearch.yml` on each node: cluster.name: my-cluster node.name: node-1 network.host: 0.0.0.0 discovery.seed_hosts: ["node1-ip", "node2-ip", "node3-ip"] cluster.initial_master_nodes: ["node-1", "node-2", "node-3"] 3. **Enable TLS:** * Generate certificates using `elasticsearch-certutil`. * Configure `elasticsearch.yml` with TLS settings. Example TLS Configuration: xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate xpack.security.transport.ssl.key: /path/to/private.key xpack.security.transport.ssl.certificate: /path/to/certificate.crt xpack.security.transport.ssl.certificate_authorities: ["/path/to/ca.crt"] 1. **Start Cluster Nodes:** Start each node individually and confirm cluster health: curl -X GET "http://node1-ip:9200/_cluster/health" #### Logstash 1. **Download and Install Logstash:** wget https://artifacts.elastic.co/downloads/logstash/logstash-<version>-linux-x86_64.tar.gz tar -xvf logstash-<version>-linux-x86_64.tar.gz cd logstash-<version> 1. **Configure Input, Filter, and Output Pipelines:** * Example Configuration (`logstash.conf`): input { beats { port => 5044 } } filter { grok { match => { "message" => "%{COMBINEDAPACHELOG}" } } } output { elasticsearch { hosts => ["localhost:9200"] index => "apache-logs" } } 2. **Run Logstash:** ./bin/logstash -f logstash.conf #### Kibana 1. **Download and Install Kibana:** wget https://artifacts.elastic.co/downloads/kibana/kibana-<version>-linux-x86_64.tar.gz tar -xvf kibana-<version>-linux-x86_64.tar.gz cd kibana-<version> 1. **Edit Configuration:** * Update `config/kibana.yml`: server.host: "0.0.0.0" elasticsearch.hosts: ["http://localhost:9200"] 2. **Run Kibana:** ./bin/kibana 1. **Access Kibana:** Visit `http://<kibana-ip>:5601`. ### 4. Installation of Beats #### Filebeat Installation and Configuration 1. **Download Filebeat:** wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-<version>-linux-x86_64.tar.gz tar -xvf filebeat-<version>-linux-x86_64.tar.gz cd filebeat-<version> 1. **Edit Configuration File:** * Open `filebeat.yml` and configure inputs: filebeat.inputs: - type: log enabled: true paths: - /var/log/apache2/access.log * Set Elasticsearch output: output.elasticsearch: hosts: ["localhost:9200"] 1. **Enable and Start Filebeat:** ./filebeat modules enable apache ./filebeat setup ./filebeat -e #### Metricbeat Installation and Configuration 1. **Download Metricbeat:** wget https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-<version>-linux-x86_64.tar.gz tar -xvf metricbeat-<version>-linux-x86_64.tar.gz cd metricbeat-<version> 1. **Edit Configuration File:** * Open `metricbeat.yml` and configure modules: metricbeat.modules: - module: system metricsets: - cpu - memory - network enabled: true period: 10s hosts: ["localhost:9200"] 1. **Enable and Start Metricbeat:** ./metricbeat modules enable system ./metricbeat setup ./metricbeat -e #### Other Beats * **Heartbeat:** For uptime monitoring. * **Packetbeat:** For network packet analysis. * **Auditbeat:** For auditing user activity and processes. Installation steps are similar to Filebeat and Metricbeat, with module-specific configurations. ### 6. Detailed Cluster Creation #### Multi-node Cluster Configuration 1. **Node Roles:** * Assign roles to nodes for better scalability and fault tolerance. * **Master Nodes:** Responsible for cluster-wide management. * **Data Nodes:** Store and handle data-related tasks like indexing and searching. * **Ingest Nodes:** Pre-process and transform data before indexing. * **Coordinating Nodes:** Handle client requests and distribute tasks across the cluster. 1. **Prepare Environment:** * Ensure all nodes have the same version of Elasticsearch installed. * Use a private network for communication between nodes. 1. **Node-Specific Configuration:** * Update `elasticsearch.yml` for each node based on its role: cluster.name: my-cluster node.name: <node-name> node.roles: [<role1>, <role2>] network.host: 0.0.0.0 discovery.seed_hosts: ["node1-ip", "node2-ip", "node3-ip"] cluster.initial_master_nodes: ["node-1", "node-2", "node-3"] 1. **Secure the Cluster:** * Generate and deploy SSL/TLS certificates to each node. * Enable security features in `elasticsearch.yml`: xpack.security.enabled: true xpack.security.transport.ssl.enabled: true xpack.security.transport.ssl.verification_mode: certificate 1. **Start and Monitor the Cluster:** * Start Elasticsearch on each node. * Verify cluster health: curl -X GET "http://<master-node-ip>:9200/_cluster/health?pretty" * Check node details: curl -X GET "http://<master-node-ip>:9200/_cat/nodes?v" ### 8. Advanced Pipelines in Logstash #### Pipeline Architecture * **Inputs:** Define data sources (e.g., Beats, syslog). * **Filters:** Apply transformations, parsing, or enrichment. * **Outputs:** Define destinations (e.g., Elasticsearch, file). #### Conditional Logic and Data Routing * Example: if [type] == "error" { output { elasticsearch { hosts => ["localhost:9200"] index => "error-logs" } } } #### Using Ruby Filters for Advanced Transformations * Example: filter { ruby { code => "event.set('formatted_message', event.get('message').upcase)" } } #### Optimizing Pipelines for Performance * Reduce memory footprint by minimizing intermediate steps. * Use bulk indexing for Elasticsearch outputs. ### 9. Security Hardening Tips #### Securing Communication Between Nodes * Use mutual TLS authentication. * Ensure certificates are from a trusted CA. #### Implementing Role-Based Access Control (RBAC) * Assign roles based on the principle of least privilege. * Example roles: * Admin: Full access * Viewer: Read-only access to dashboards #### Using Encryption for Data at Rest * Enable disk encryption for Elasticsearch data directories. #### Regular Security Audits and Patching * Periodically update ELK Stack components to the latest versions. * Review logs for unauthorized access attempts. ### 10. Kibana Dev Tools and Console #### Introduction to Kibana Console * Accessible via the "Dev Tools" section in Kibana. * Provides an interactive interface to query Elasticsearch. #### Writing and Testing Elasticsearch Queries * Example query to fetch all documents: GET /_search { "query": { "match_all": {} } } #### Managing Index Patterns * Define patterns to group similar indices (e.g., `logstash-*`). * Use the "Index Management" tool in Kibana. #### Examples of Advanced Queries * Aggregation query: GET /logs/_search { "aggs

Logstash http output plugin: difference between json and json_batch format The http output plugin of Logstash supports multiple formats. But what is the actual difference between json and json_batch formats?

When you use the #Logstash http output plugin, you can send logs to a HTTP endpoint, sometimes also named #logsink. 🪵 ⬇️

The format setting allows a couple of options. But what is the actual difference between the default "json" value and "json_batch"? 🤔

Log manipulation and alteration with Logstash mutate filter The Logstash mutate filter is a powerful filter to manipulate and alter log events.

If log events need to be altered or manipulated, there's the #Logstash mutate filter.
Needed to use this filter in a large #observability stack, to get rid of unnecessary (meta) data and rename fields as required by an external data API. Works great ❤️.
