Begin Monitoring One Host

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

Resource

POST /groups/{PROJECT-ID}/hosts

Request Path Parameters

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

Request Query Parameters

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

Request Body Parameters

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
  • PLAIN
  • MONGODB_X509
  • NONE
hostname string 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 boolean Conditional

Flag indicating whether TLS should be enabled for this MongoDB process.

Set to true if "authMechanismName" : "MONGODB_X509".

username string Conditional

Username needed to connect to this MongoDB process.

Required if "authMechanismName" : "MONGODB_CR"

Response

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.
slaveDelaySec 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 slave 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
  • MASTER
  • SLAVE
  • 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.
