| 10 | + |
| 11 | +You can use {filebeat} to monitor the {es} log files, collect log events, and |
| 12 | +ship them to the monitoring cluster. Your recent logs are visible on the |
| 13 | +*Monitoring* page in {kib}. |
| 14 | + |
| 15 | +//NOTE: The tagged regions are re-used in the Stack Overview. |
| 16 | + |
| 17 | +. Verify that {es} is running and that the monitoring cluster is ready to |
| 18 | +receive data from {filebeat}. |
| 19 | ++ |
| 20 | +-- |
| 21 | +TIP: In production environments, we strongly recommend using a separate cluster |
| 22 | +(referred to as the _monitoring cluster_) to store the data. Using a separate |
| 23 | +monitoring cluster prevents production cluster outages from impacting your |
| 24 | +ability to access your monitoring data. It also prevents monitoring activities |
| 25 | +from impacting the performance of your production cluster. See |
| 26 | +{stack-ov}/monitoring-production.html[Monitoring in a production environment]. |

| 41 | +The {filebeat} {es} module can handle |
| 42 | +{stack-ov}/audit-log-output.html[audit logs], |
| 43 | +{ref}/logging.html#deprecation-logging[deprecation logs], |
| 44 | +{ref}/gc-logging.html[gc logs], {ref}/logging.html[server logs], and |
| 45 | +{ref}/index-modules-slowlog.html[slow logs]. |
| 46 | +For more information about the location of your {es} logs, see the |
| 47 | +{ref}/path-settings.html[path.logs] setting. |
| 48 | + |
| 49 | +IMPORTANT: If there are both structured (`*.json`) and unstructured (plain text) |
| 50 | +versions of the logs, you must use the structured logs. Otherwise, they might |
| 51 | +not appear in the appropriate context in {kib}. |

| 56 | +nodes that contain logs that you want to monitor. |

| 58 | +. Identify where to send the log data. |
| 59 | ++ |
| 60 | +-- |
| 61 | +// tag::output-elasticsearch[] |
| 62 | +For example, specify {es} output information for your monitoring cluster in |
| 63 | +the {filebeat} configuration file (`filebeat.yml`): |
| 64 | + |
| 65 | +[source,yaml] |
| 66 | +---------------------------------- |
| 67 | +output.elasticsearch: |
| 68 | + # Array of hosts to connect to. |
| 69 | + hosts: ["http://es-mon-1:9200", "http://es-mon2:9200"] <1> |
| 70 | +
|
| 71 | + # Optional protocol and basic auth credentials. |
| 72 | + #protocol: "https" |
| 73 | + #username: "elastic" |
| 74 | + #password: "changeme" |
| 75 | +---------------------------------- |
| 76 | +<1> In this example, the data is stored on a monitoring cluster with nodes |
| 77 | +`es-mon-1` and `es-mon-2`. |
| 78 | + |
| 79 | +If you configured the monitoring cluster to use encrypted communications, you |
| 80 | +must access it via HTTPS. For example, use a `hosts` setting like |
| 81 | +`https://es-mon-1:9200`. |
| 82 | + |
| 83 | +IMPORTANT: The {es} {monitor-features} use ingest pipelines, therefore the |
| 84 | +cluster that stores the monitoring data must have at least one |
| 85 | +<<ingest,ingest node>>. |
| 86 | + |
| 87 | +If {es} {security-features} are enabled on the monitoring cluster, you must |
| 88 | +provide a valid user ID and password so that {filebeat} can send metrics |
| 89 | +successfully. |
| 90 | + |
| 91 | +For more information about these configuration options, see |
| 92 | +{filebeat-ref}/elasticsearch-output.html[Configure the {es} output]. |
| 93 | +// end::output-elasticsearch[] |
| 94 | +-- |
| 95 | + |
| 96 | +. Optional: Identify where to visualize the data. |
| 97 | ++ |
| 98 | +-- |
| 99 | +// tag::setup-kibana[] |
| 100 | +{filebeat} provides example {kib} dashboards, visualizations and searches. To |
| 101 | +load the dashboards into the appropriate {kib} instance, specify the |
| 102 | +`setup.kibana` information in the {filebeat} configuration file |
| 103 | +(`filebeat.yml`) on each node: |
| 104 | + |
| 105 | +[source,yaml] |
| 106 | +---------------------------------- |
| 107 | +setup.kibana: |
| 108 | + host: "localhost:5601" |
| 109 | + #username: "my_kibana_user" |
| 110 | + #password: "YOUR_PASSWORD" |
| 111 | +---------------------------------- |
| 112 | + |
| 113 | +TIP: In production environments, we strongly recommend using a dedicated {kib} |
| 114 | +instance for your monitoring cluster. |
| 115 | + |
| 116 | +If {security-features} are enabled, you must provide a valid user ID and |
| 117 | +password so that {filebeat} can connect to {kib}: |
| 118 | + |
| 119 | +.. Create a user on the monitoring cluster that has the |
| 120 | +{stack-ov}/built-in-roles.html[`kibana_user` built-in role] or equivalent |
| 121 | +privileges. |
| 122 | + |
| 123 | +.. Add the `username` and `password` settings to the {es} output information in |
| 124 | +the {filebeat} configuration file. The example shows a hard-coded password, but |
| 125 | +you should store sensitive values in the |
| 126 | +{filebeat-ref}/keystore.html[secrets keystore]. |
| 127 | + |
| 128 | +See {filebeat-ref}/setup-kibana-endpoint.html[Configure the {kib} endpoint]. |

| 131 | +-- |
| 132 | + |
| 133 | +. Enable the {es} module and set up the initial {filebeat} environment on each |
| 134 | +node. |

| 153 | ++ |

| 155 | +// tag::configure-es-module[] |
| 156 | +If the logs that you want to monitor aren't in the default location, set the |
| 157 | +appropriate path variables in the `modules.d/elasticsearch.yml` file. See |
| 158 | +{filebeat-ref}/filebeat-module-elasticsearch.html#configuring-elasticsearch-module[Configure the {es} module]. |
| 159 | + |

| 178 | +For example, use the {ref}/cat-indices.html[cat indices] command to verify |
| 179 | +that there are new `filebeat-*` indices. |
| 180 | + |
| 181 | +TIP: If you want to use the *Monitoring* UI in {kib}, there must also be |
| 182 | +`.monitoring-*` indices. Those indices are generated when you collect metrics |
| 183 | +about {stack} products. For example, see <<configuring-metricbeat>>. |
