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.

Get all MongoDB hosts in a project. Use the CLUSTER-ID query parameter to only get the hosts that belong to the specified cluster. The response sorts the hosts alphabetically by HOSTNAME:PORT.

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

Resource

GET /groups/{PROJECT-ID}/hosts
GET /groups/{PROJECT-ID}/hosts?clusterId={CLUSTER-ID}

Request Path Parameters

Parameter
Type
Necessity
Description
PROJECT-ID
string
Required
Unique identifier of the project that owns this MongoDB host.

Request Query Parameters

Name
Type
Necessity
Description
Default
pageNum
number
Optional
One-based integer that returns a subsection of results.
1
itemsPerPage
number
Optional
Number of items to return per page, up to a maximum of 500.
100
pretty
boolean
Optional
Flag that indicates 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 a list of results, the results object is an envelope. Ops Manager adds the status field to the response body.

false
backupJobsEnabledOnly
boolean
Optional
Flag indicating whether to exclude daemons not enabled for backing up databases from the response. Set this to false to include daemon configurations with the backupJobsEnabled flag set to false.
true
Parameter
Type
Necessity
Description
CLUSTER-ID
string
Required
Unique identifier of the cluster in which this MongoDB process belongs.

Request Body Parameters

This endpoint doesn't use HTTP request body parameters.

Response

Response Document

The response JSON document includes an array of result objects, an array of link objects and a count of the total number of result objects retrieved.

Name
Type
Description
results
array
Array includes one object for each item detailed in the results Embedded Document section.
links
array
Array includes one or more links to sub-resources and/or related resources. The relations between URLs are explained in the Web Linking Specification.
totalCount
number
Integer count of the total number of items in the result set. It may be greater than the number of objects in the results array if the entire result set is paginated.

results Embedded Document

Each result is one host.

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
Unique identifier of the cluster to which the MongoDB process belongs.
created
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.
hidden
boolean
true if host is displayed in the Ops Manager UI. Hosts set to true are omitted from API responses.
hiddenSecondary
boolean
true if this host is a hidden secondary.
hostEnabled
boolean
true if the MongoDB process currently enabled.
hostname
string
Primary hostname as Ops Manager can best determine. This can be a hostname, an FQDN, an IPv4 address, or an IPv6 address.
id
string
Unique identifier.
ipAddress
string
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
sslEnabled
boolean
true if TLS/SSL and is enabled for this MongoDB process.
systemInfo
object
Object that contains RAM and CPU information for this MongoDB process' server as reported by the operating system or container.
systemInfo.memSizeMB
number
Amount of RAM in megabytes.
systemInfo.numCores
number
Number of CPU cores.
typeName
string

Type for this MongoDB process. Possible values are:

  • STANDALONE

  • REPLICA_PRIMARY

  • REPLICA_SECONDARY

  • REPLICA_ARBITER

  • RECOVERING

  • SHARD_MONGOS

  • SHARD_CONFIG

  • SHARD_STANDALONE

  • SHARD_PRIMARY

  • SHARD_SECONDARY

  • NO_DATA

The type for new hosts added to Ops Manager will be NO_DATA until the Monitoring receives its first ping.

uptimeMsec
number
Number of milliseconds since this process last restarted.
version
string
Version of MongoDB running for this process.

Note

Some hosts don't return clusterId. This occurs when a mongos process routes data operations to shards that don't store data. Ops Manager doesn't assign a clusterId to some non-data bearing nodes.

Example Request

curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
 --header "Accept: application/json" \
 --include \
 --request GET "https://{OPSMANAGER-HOST}:{PORT}/api/public/v1.0/groups/{PROJECT-ID}/hosts?pretty=true"
