Hi Team, I'm trying to send application logs (filebeat -\> logstash-\> kafka topic) to kafka stream. For some reason I'm not able to see logs in kafka. Here is my filebeat.conf ```auto filebeat.spool_size: 2048 filebeat.idle_timeout: 5s fields: envName: gxpbt output.logstash: hosts: ['xyz.logstash.com:6045'] filebeat.inputs: - type: log paths: - /var/log/osquery/xyz.results.log multiline.type: pattern multiline.pattern: '^{' multiline.negate: true multiline.match: after fields: host_ip: "10.0.0.1" hostname: "test-compute" logtype: osquerylog json.message_key: log ``` Logstash conf file: ```auto input { beats { port => 6045 } } filter { if [fields][logtype] == "osquerylog" { grok { match => ["[log][file][path]", "%{GREEDYDATA:message}"] add_tag => "osquerylog" } } } output { if "osquerylog" in [tags] { kafka { codec => "json" bootstrap_servers => "https://xyz.kafka.com:9092" ssl_truststore_location => "/etc/certs/kafkatruststore.jks" ssl_truststore_password => "1234567" ssl_truststore_type => "JKS" ssl_keystore_location => "/etc/certs/kafkakeystore.jks" ssl_keystore_password => "1234567" ssl_keystore_type => "JKS" sasl_mechanism => "PLAIN" security_protocol => "SASL_SSL" request_timeout_ms => "5000" sasl_jaas_config => "org.apache.kafka.common.security.plain.PlainLoginModule required username='test' password='test123';" topic_id => "osquery_log" } } } ``` I'm seeing following log messages in logstash logs, ```auto [2022-07-12T20:19:48,773][INFO][org.apache.kafka.common.security.authenticator.AbstractLogin][main] Successfully logged in. [2022-07-12T20:19:48,846][INFO][org.apache.kafka.common.utils.AppInfoParser][main] Kafka version: 2.5.1 [2022-07-12T20:19:48,846][INFO][org.apache.kafka.common.utils.AppInfoParser][main] Kafka commitId: 0efa8fb0f4c73d92 [2022-07-12T20:19:48,846][INFO][org.apache.kafka.common.utils.AppInfoParser][main] Kafka startTimeMs: 1657657188843 ``` Please help me understand why I am not able to see events in kafka. ---

The first step would be to add ``` output { stdout { codec => rubydebug } } ``` (or a file output) to make sure that the events are reaching logstash and have the fields that you expect. ---

Thanks for your reply. I can see logs being sent, because of the kafka stream offset all events were not reaching. I'have following filebeat.conf file, ```auto fields: envName: gxpbt output.logstash: hosts: ['xyz.logstash.com:6045'] filebeat.inputs: - type: log paths: - /var/log/osquery/osquery.results.log multiline.type: pattern multiline.pattern: '^{' multiline.negate: true multiline.match: after fields: host_ip: "10.0.0.1" hostname: "test-compute" regio: "ashburn" json.message_key: log' - type: log paths: - /var/log/hostname/forwarded-logs.log fields: logtype: rsyslog - type: log paths: - /u01/data/domains/*_domain/servers/*/logs/access.log fields: logtype: wlsAccess ``` Logstash.conf: ```auto input { beats { port => 6045 } } if [fields][region] == "ashburn" { grok { match => ["message", "%{GREEDYDATA:message}"] add_tag => "osquerylog" } } if [fields][logtype] == "wlsAccess" { grok { match => ["[log][file][path]","%{GREEDYDATA}/%{DATA:servername}/logs/%{DATA:dirname}/%{GREEDYDATA:filename}"] } } if [fields][logtype] == "rsyslog" { grok { match => ["message", "%{GREEDYDATA:message}"] add_tag => "rsyslog" } } else { grok { match => ["[log][file][path]","%{GREEDYDATA}/%{DATA:servername}/logs/%{GREEDYDATA:filename}"] } } output { if "osquerylog" in [tags] { kafka { codec => "json" bootstrap_servers => "https://xyz.kafka.com:9092" ssl_truststore_location => "/etc/certs/kafkatruststore.jks" ssl_truststore_password => "1234567" ssl_truststore_type => "JKS" ssl_keystore_location => "/etc/certs/kafkakeystore.jks" ssl_keystore_password => "1234567" ssl_keystore_type => "JKS" sasl_mechanism => "PLAIN" security_protocol => "SASL_SSL" request_timeout_ms => "5000" sasl_jaas_config => "org.apache.kafka.common.security.plain.PlainLoginModule required username='test' password='test123';" topic_id => "osquery_log" } } if "rsyslog" in [tags] { syslog { appname => "SIEM" host => "10.x.x.52" port => "514" protocol => "tcp" codec => line { format => "%{message}" } } } stdout{} else{ file { codec => line { format => "%{[message]}" } path => "/mnt/shared_fs_03/%{[fields][envName]}/%{[host][name]}/%{[servername]}/%{[filename]}-%{+YYYY-MM-dd}" } #stdout{} } } ``` Could you please confirm if I can use **IF** and **else** conditions and filters? ---

@Badger For example I have field "region is ashburn" under filebeat.conf. can I use the if condition as above. Can I write if else conditions as above? ---

Provided that the names match (region vs. regio) then the answer to both questions is yes. ---
