Kibana8.5破解白金版，配置webhook推送日志告警到钉钉

前提：你已经安装好了Elasticsearch和Kibana，Elastic分为基础版、白金版和企业版。告警推送通道只有白金版才支持webhook，所以需要进行破解。

1：下载源代码文件

破解Elastic需要修改两个java文件，分别为LicenseVerifier.java和XPackBuild.java,我们从github上下载对应的源文件，注意你的Elasticsearch版本，修改url中对应的版本号即可，我这里是8.5.

curl -o LicenseVerifier.java -s https://raw.githubusercontent.com/elastic/elasticsearch/8.5/x-pack/plugin/core/src/main/java/org/elasticsearch/license/LicenseVerifier.java
curl -o XPackBuild.java -s https://raw.githubusercontent.com/elastic/elasticsearch/8.5/x-pack/plugin/core/src/main/java/org/elasticsearch/xpack/core/XPackBuild.java

2：修改代码

修改XPackBuild.java，在第一个静态方法中的if、else是判断jar包有没有被修改的，我们修改这段代码。

import java.net.URL;
import java.nio.file.Files;
import java.nio.file.Path;
import java.util.jar.JarInputStream;
import java.util.jar.Manifest;

/**
 * Information about the built version of x-pack that is running.
 */
public class XPackBuild {
   

    public static final XPackBuild CURRENT;

    static {
   
        final String shortHash;
        final String date;

        Path path = getElasticsearchCodebase();
        /*if (path.toString().endsWith(".jar")) {
            try (JarInputStream jar = new JarInputStream(Files.newInputStream(path))) {
                Manifest manifest = jar.getManifest();
                shortHash = manifest.getMainAttributes().getValue("Change");
                date = manifest.getMainAttributes().getValue("Build-Date");
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        } else {
            // not running from a jar (unit tests, IDE)
            shortHash = "Unknown";
            date = "Unknown";
        }*/

		shortHash = "Unknown";
		date = "Unknown";
        CURRENT = new XPackBuild(shortHash, date);
    }

    /**
     * Returns path to xpack codebase path
     */
    @SuppressForbidden(reason = "looks up path of xpack.jar directly")
    static Path getElasticsearchCodebase() {
   
        URL url = XPackBuild.class.getProtectionDomain().getCodeSource().getLocation();
        try {
   
            return PathUtils.get(url.toURI());
        } catch (URISyntaxException bogus) {
   
            throw new RuntimeException(bogus);
        }
    }

    private String shortHash;
    private String date
