MongoDB module
editMongoDB module
editThis module periodically fetches metrics from MongoDB servers.
Module-specific configuration notes
editWhen configuring the hosts
option, you must use MongoDB URLs of the following
format:
[mongodb://][user:pass@]host[:port][?options]
The URL can be as simple as:
- module: mongodb hosts: ["localhost"]
Or more complex like:
- module: mongodb hosts: ["mongodb://myuser:mypass@localhost:40001", "otherhost:40001"]
The username and password can be included in the URL or they can be set using the respective configuration options. The credentials in the URL take precedence over the username and password configuration options.
- module: mongodb metricsets: ["status"] hosts: ["localhost:27017"] username: root password: test
The default metricsets are collstats
, dbstats
and status
.
Compatibility
editThe MongoDB metricsets were tested with MongoDB 3.4 and 3.0 and are expected to work with all versions >= 2.8.
MongoDB Privileges
editIn order to use the metricsets, the MongoDB user specified in the module configuration needs to have certain privileges.
We recommend using the clusterMonitor
role to cover all the necessary privileges.
You can use the following command in Mongo shell to create the privileged user (make sure you are using the admin
db by using db
command in Mongo shell).
db.createUser( { user: "beats", pwd: "pass", roles: ["clusterMonitor"] } )
You can use the following command in Mongo shell to grant the role to an existing user (make sure you are using the admin
db by using db
command in Mongo shell).
db.grantRolesToUser("user", ["clusterMonitor"])
The MongoDB module supports the standard configuration options that are described in Modules. Here is an example configuration:
metricbeat.modules: - module: mongodb metricsets: ["dbstats", "status", "collstats", "metrics", "replstatus"] period: 10s enabled: true # The hosts must be passed as MongoDB URLs in the format: # [mongodb://][user:pass@]host[:port]. # The username and password can also be set using the respective configuration # options. The credentials in the URL take precedence over the username and # password configuration options. hosts: ["localhost:27017"] # Optional SSL. By default is off. #ssl.enabled: true # Mode of verification of server certificate ('none' or 'full') #ssl.verification_mode: 'full' # List of root certificates for TLS server verifications #ssl.certificate_authorities: ["/etc/pki/root/ca.pem"] # Certificate for SSL client authentication #ssl.certificate: "/etc/pki/client/cert.pem" # Client Certificate Key #ssl.key: "/etc/pki/client/cert.key" # Username to use when connecting to MongoDB. Empty by default. #username: user # Password to use when connecting to MongoDB. Empty by default. #password: pass
This module supports TLS connections when using ssl
config field, as described in SSL.
The following metricsets are available:
