Note

Groups and projects are synonymous terms. Your {PROJECT-ID} is the same as your project id. For existing groups, your group/project id remains the same. This page uses the more familiar term group when referring to descriptions. The endpoint remains as stated in the document.

Start monitoring a new MongoDB process. The Monitoring starts monitoring the MongoDB process on the hostname and port you specify. Ops Manager knows only the information that you provide. The response document includes blank values until Ops Manager completes discovery of the MongoDB processes configuration.

Base URL: https://{OPSMANAGER-HOST}:{PORT}/api/public/v1.0

POST /groups/{PROJECT-ID}/hosts
Parameter
Type
Necessity
Description
PROJECT-ID
string
Required
Unique identifier of the project that owns this MongoDB process.

The following query parameters are optional:

Name
Type
Necessity
Description
Default
pretty
boolean
Optional
Flag indicating whether the response body should be in a prettyprint format.
false
envelope
boolean
Optional

Flag that indicates whether or not to wrap the response in an envelope.

Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:

Name
Description
status
HTTP response code
envelope
Expected response body
false
Name
Type
Necessity
Description
alertsEnabled
boolean
Optional
Set to true if alerts should be enabled for this MongoDB process.
authMechanismName
string
Optional

Specify which authentication mechanism should be used to connect to this MongoDB process. Possible values are:

  • MONGODB_CR (This covers SCRAM-SHA-1, SCRAM-SHA-256, and MONGODB-CR.)

  • GSSAPI

Required
Set the primary hostname Ops Manager should use to connect to this MongoDB instance.
logsEnabled
boolean
Optional
Set to true if Ops Manager should collect logs for this MongoDB process.
password
string
Optional

Password associated with username for connecting to this MongoDB process.

Set this parameter if "authMechanismName" : "MONGODB_CR"

Ops Manager doesn't include this parameter in any Host || response.

port
number
Required
Port on which MongoDB process listens.
profilerEnabled
boolean
Optional
Flag indicating whether Ops Manager collects profile information from this MongoDB process.
sslEnabled

string
Conditional

Username needed to connect to this MongoDB process.

Required if "authMechanismName" : "MONGODB_CR"

Name
Type
Description
aliases
array of strings
Array of alternate hostname and port combinations that Ops Manager discovered for the MongoDB process. These combinations can include hostnames, FQDNs, IPv4 addresses, and IPv6 addresses.
alertsEnabled
boolean
true if this MongoDB process has alerts enabled.
authMechanismName
string

Authentication mechanism used to connect to this MongoDB process. This displays only one of the following values:

  • MONGODB_CR (This covers SCRAM-SHA-1, SCRAM-SHA-256, and MONGODB-CR.)

  • GSSAPI

  • PLAIN

  • MONGODB_X509

  • NONE

clusterId
string

date
Date Ops Manager created or first discovered this MongoDB process.
groupId
string
Unique identifier of the group that owns this host.
hasStartupWarnings
boolean
true if this MongoDB process had startup warnings.

IPv4 or IPv6 address associated with the hostname of this MongoDB process. Additional accessible IPv4 or IPv6 addresses may be displayed in the aliases array.
journalingEnabled
boolean
true if journaling is enabled for this MongoDB process.
lastDataSizeBytes
number
Uncompressed size of the host's databases on disk in bytes excluding indexes. lastDataSizeBytes does not include the data in the local database.
lastIndexSizeBytes
number
Uncompressed size of the host's database indexes on disk in bytes. This number does not include the size of the index for the local database.
lastPing
date
Timestamp in ISO 8601 date and time format in UTC when the last ping for this MongoDB process was received.
lastRestart
date
Timestamp in ISO 8601 date and time format in UTC when this process last restarted. If the MongoDB process has never been restarted, the lastRestart field is omitted.
links
array
Array that includes one or more links to sub-resources and/or related resources. The relations between URLs are explained in the Web Linking Specification. At minimum, a links array contains one link called self.
logsEnabled
boolean
true if Ops Manager is collecting logs for this MongoDB process.
lowUlimit
boolean
true if this MongoDB process's host has a low ulimit setting.
port
number
Port on which the MongoDB process listens.
profilerEnabled
boolean
true if Ops Manager collects profile information from this MongoDB process.
replicaSetName
string
Name of the replica set this process belongs to. Only present if this process is part of a replica set.
replicaStateName
string
Current state of this MongoDB process within a replica set. Only present if this process is part of a replica set. See Replica Set Member States for possible values.
shardName
string
Name of the shard to which this process belongs. Only present if the process is part of a sharded cluster.
secondaryDelaySecs
number
Number of seconds this replica set member's data trails the primary. If this value is set to 0, the member is not configured as a delayed member. For additional details on secondary delays, see Delayed Replica Set Members
