quelle est la version de la stack que vous utiliser ? Elasticsearch et Kibana
Kibana version 7.9.3
Elasticsearch 7.9.3
Votre Kibana n'arrive pas peut a communiquer avec elasticsearch
Vérifier que vous ariver à accéder à elasticsearch depuis http://localhost:9200
Partager votre config (elasticsearch.yml et kibana.yml) et décrire un peu les étpapes pour reproduire le problème ...
voici pour elasticsearch.yml je n'ai rien modifier
======================== Elasticsearch Configuration =========================
voici pour kibana.yml
Kibana is served by a back end server. This setting specifies the port to use.
server.port: 5601
Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
The default is 'localhost', which usually means remote machines will not be able to connect.
To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "0.0.0.0"
Enables you to specify a path to mount Kibana at if you are running behind a proxy.
Use the server.rewriteBasePath setting to tell Kibana if it should remove the basePath
from requests it receives, and to prevent a deprecation warning at startup.
This setting cannot end in a slash.
#server.basePath: ""
Specifies whether Kibana should rewrite requests that are prefixed with
server.basePath or require that they are rewritten by your reverse proxy.
This setting was effectively always false before Kibana 6.3 and will
default to true starting in Kibana 7.0.
#server.rewriteBasePath: false
The maximum payload size in bytes for incoming server requests.
#server.maxPayloadBytes: 1048576
The Kibana server's name. This is used for display purposes.
#server.name: "your-hostname"
The URLs of the Elasticsearch instances to use for all your queries.
elasticsearch.hosts: ["http://localhost:9200"]
When this setting's value is true Kibana uses the hostname specified in the server.host
setting. When the value of this setting is false, Kibana uses the hostname of the host
that connects to this Kibana instance.
elasticsearch.preserveHost: true
Kibana uses an index in Elasticsearch to store saved searches, visualizations and
dashboards. Kibana creates a new index if the index doesn't already exist.
kibana.index: ".kibana"
The default application to load.
kibana.defaultAppId: "discover"
If your Elasticsearch is protected with basic authentication, these settings provide
the username and password that the Kibana server uses to perform maintenance on the Kibana
index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
is proxied through the Kibana server.
#elasticsearch.username: "kibana_system"
#elasticsearch.password: "pass"
Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
These settings enable SSL for outgoing requests from the Kibana server to the browser.
#server.ssl.enabled: false
#server.ssl.certificate: /path/to/your/server.crt
#server.ssl.key: /path/to/your/server.key
Optional settings that provide the paths to the PEM-format SSL certificate and key files.
These files are used to verify the identity of Kibana to Elasticsearch and are required when
xpack.security.http.ssl.client_authentication in Elasticsearch is set to required.
#elasticsearch.ssl.certificate: /path/to/your/client.crt
#elasticsearch.ssl.key: /path/to/your/client.key
Optional setting that enables you to specify a path to the PEM file for the certificate
authority for your Elasticsearch instance.
#elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]
To disregard the validity of SSL certificates, change this setting's value to 'none'.
#elasticsearch.ssl.verificationMode: full
Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of
the elasticsearch.requestTimeout setting.
#elasticsearch.pingTimeout: 1500
Time in milliseconds to wait for responses from the back end or Elasticsearch. This value
must be a positive integer.
elasticsearch.requestTimeout: 30000
List of Kibana client-side headers to send to Elasticsearch. To send no client-side
headers, set this value to (an empty list).
#elasticsearch.requestHeadersWhitelist: [ authorization ]
Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten
by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.
#elasticsearch.customHeaders: {}
Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.
elasticsearch.shardTimeout: 0
Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying.
#elasticsearch.startupTimeout: 5000
Logs queries sent to Elasticsearch. Requires logging.verbose set to true.
#elasticsearch.logQueries: false
Specifies the path where Kibana creates the process ID file.
#pid.file: /var/run/kibana.pid
Enables you to specify a file where Kibana stores log output.
#logging.dest: stdout
Set the value of this setting to true to suppress all logging output.
#logging.silent: false
Set the value of this setting to true to suppress all logging output other than error messages.
#logging.quiet: false
Set the value of this setting to true to log all events, including system usage information
and all requests.
#logging.verbose: false
Set the interval in milliseconds to sample system and process performance
metrics. Minimum is 100ms. Defaults to 5000.
#ops.interval: 5000
Specifies locale to be used for all localizable strings, dates and number formats.
Supported languages are the following: English - en , by default , Chinese - zh-CN .
#i18n.locale: "en"
Je vois que c'est la config par défaut
Comment tu as installé Kibana et comment tu la lance ?
If you've installed Kibana using the package manager (e.g. `apt` ), you should start kibana using `sudo systemctl start kibana.service` or otherwise it will not read the `kibana.yml` configuration file.
J'ai téléchargé le package zip pour Windows, extrait le fichier et j'ai copié le chemin jusqu'à \bin\kibana et exécuté
