== Installing Marvel
|
||
|
||
To use Marvel, you need to install two components:
|
||
|
||
* An Elasticsearch plugin that collects data from each node in your cluster.
|
||
This plugin must be installed on every node.
|
||
* A Kibana app that provides the Marvel monitoring and management UI.
|
||
|
||
By default, the Marvel plugin stores data in the same Elasticsearch cluster
|
||
where it is installed. If you are monitoring a production cluster we recommend
|
||
that you store the Marvel data in a separate monitoring cluster. Sending the Marvel
|
||
data to a monitoring cluster helps ensure that you can continue to monitor your
|
||
production cluster if it's in an unhealthy state.
|
||
|
||
For basic installation instructions, see <<getting-started, Getting Started with Marvel>>. For
|
||
information about storing Marvel data in a separate monitoring cluster, see <<monitoring-cluster,
|
||
Setting up a Separate Monitoring Cluster>>.

[[package-installation]]
|
||
=== Installing Marvel on a DEB/RPM Package Installation
|
||
|
||
If you use the DEB/RPM packages to install Elasticsearch, by default Elasticsearch is installed in
|
||
`/usr/share/elasticsearch` and the configuration files are stored in `/etc/elasticsearch`. (For the
|
||
complete list of default paths, see {ref}/setup-dir-layout.html#_deb_and_rpm[Directory Layout] in
|
||
the Elasticsearch Reference.)
|
||
|
||
To install the Marvel and License plugins on a DEB/RPM package installation, you need to run
|
||
`bin/plugin -i` from the `/usr/share/elasticsearch` directory with superuser permissions, and
|
||
specify the location of the configuration files by setting `-Des.path.conf`. For example:
|
||
|
||
[source,shell]
|
||
----------------------------------------------------------
|
||
cd /usr/share/elasticsearch
|
||
sudo bin/plugin -i elasticsearch/license/latest -Des.path.conf=/etc/elasticsearch
|
||
sudo bin/plugin -i elasticsearch/marvel/latest -Des.path.conf=/etc/elasticsearch
|
||
----------------------------------------------------------

[[offline-installation]]
|
||
=== Installing Marvel on Offline Machines
|
||
|
||
Elasticsearch’s `bin/plugin` script requires direct Internet access to download and install the
|
||
License and Marvel plugins. If your server doesn’t have Internet access, you can manually
|
||
download and install the plugins.
|
||
|
||
To install Marvel on a machine that doesn't have Internet access:
|
||
|
||
. Manually download the License and Marvel binaries:
|
||
+
|
||
** https://download.elastic.co/elasticsearch/license/license-latest.zip[
|
||
https://download.elastic.co/elasticsearch/license/license-latest.zip]
|
||
** https://download.elastic.co/elasticsearch/marvel/marvel-latest.zip[
|
||
https://download.elastic.co/elasticsearch/marvel/marvel-latest.zip]
|
||
|
||
. Transfer the zip files to the offline machine.
|
||
|
||
. Run `bin/plugin` with the `-u` option to install the plugins using the zip files. For example:
|
||
+
|
||
[source,shell]
|
||
----------------------------------------------------------
|
||
bin/plugin -i license -u file:///path/to/file/license-latest.zip <1>
|
||
bin/plugin -i marvel -u file:///path/to/file/marvel-latest.zip
|
||
----------------------------------------------------------
|
||
<1> Note that you must specify an absolute path to the zip file after the `file://` protocol.

[[monitoring-cluster]]
|
||
=== Setting up a Separate Monitoring Cluster
|
||
|
||
To store Marvel data in a separate monitoring cluster:
|
||
|
||
. Set up the Elasticsearch cluster you want to use for monitoring. For example, a two host cluster
|
||
with the nodes `es-mon-1` and `es-mon-2`.
|
||
|
||
. Disable Marvel data collection for the nodes in your monitoring cluster by configuring the
|
||
`marvel.agent.enabled` setting in their `elasticsearch.yml` configuration files.
|
||
+
|
||
[source,yaml]
|
||
------------------------
|
||
marvel.agent.enabled: false
|
||
------------------------
|
||
|
||
. Install the Marvel and License plugins on the nodes in your monitoring cluster:
|
||
+
|
||
[source,sh]
|
||
----------------
|
||
bin/plugin -i elasticsearch/license/latest
|
||
bin/plugin -i elasticsearch/marvel/latest
|
||
----------------
|
||
|
||
. Start Elasticsearch on the nodes in your monitoring cluster:
|
||
+
|
||
[source,shell]
|
||
----------------------------------------------------------
|
||
bin/elasticsearch
|
||
----------------------------------------------------------
|
||
|
||
. Configure the nodes in your production cluster to send Marvel data to your monitoring cluster by
|
||
configuring the `marvel.agent.exporter.es.hosts` setting in their `elasticsearch.yml`
|
||
configuration files:
|
||
+
|
||
[source,yaml]
|
||
------------------------
|
||
marvel.agent.exporter.es.hosts: ["es-mon-1:9200","es-mon-2:9200"]
|
||
------------------------
|
||
|
||
. Install the Marvel and License plugins on the nodes in your production cluster:
|
||
+
|
||
[source,sh]
|
||
----------------
|
||
bin/plugin -i elasticsearch/license/latest
|
||
bin/plugin -i elasticsearch/marvel/latest
|
||
----------------
|
||
|
||
|
||
. Restart Elasticsearch on the nodes in your production cluster
|
||
+
|
||
[source,shell]
|
||
----------------------------------------------------------
|
||
bin/elasticsearch
|
||
---------------------------------------------------------
|
||
+
|
||
TIP: You may want to temporarily {ref}/modules-cluster.html[disable shard
|
||
allocation] before you restart your nodes to avoid unnecessary shard
|
||
reallocation during the install process.
|
||
|
||
. Install the Marvel app into Kibana.
|
||
|
||
. Run Kibana and open the Marvel app to verify the installation. You should
|
||
see an overview of your cluster's status: |
