mms-api

Minimalistic MMS API agent for ruby

Installation

gem install mms-api

API coverage

The MMS Public API follows the principles of the REST architectural style to expose a number of internal resources which enable programmatic access to MMS’s features. Current implementation support only a few of API features.

Resource	Get All	Get One	Create	Update	Delete
Groups	+	+	-	-	-
Hosts	+	+	+	+	+
Clusters	+	+	x	+	x
Snapshots	+	+	x	x	-
Alerts	+	+	x	-	x
Restore Jobs	+	+	+	x	x
Backup Configs	+	+	x	-	x
Metrics	+	+	x	x	x

Library usage

Source code itself is well-documented so when writing code it should auto-complete and hint in all supported usages.

Client

Most important part of the api is client. In order to make any request you need to instantiate client with correct params.

client = MMS::Client.new('username', 'api_key')

This client is used by all other classes connecting to api no matter if it's Resource or helper class like Agent.

Agent

Agent is simple wrapper class for listing all accessible resources.

client = MMS::Client.new('username', 'api_key')
agent = MMS::Agent.new(client)

agent.alerts.each do |alert|
    alert.ack('now')
end

List of resource-listing agent methods:

• groups
• hosts
• clusters
• snapshots
• alerts
• restorejobs

Resources

You can find lists of resource by using agent as pointed above, or by various resource methods. Each resource have a find method loading certain resource with provided id (plus corresponding parent ids), e.g.

client = new MMS::Client.new('username', 'api_key')
host = MMS::Resource::Host.find(client, 'group_id', 'host_id')

Additionally some resources have additional instance methods to retrieve sub-resources, e.g.

client = new MMS::Client.new('username', 'api_key')
group = MMS::Resource::Group.find(client, 'group_id')
hosts = group.hosts

Metrics

(Not available via CLI)

You can list the available metrics on each host. The list contains the resource type MMS::Resource::Metric. This can be used to see which performance metrics the host has.

In order to get the metric's data points you'll need to call the specific function.

Note - you can send a hash containing query parameter. With no input it uses MMS default.

The return value of the data points is the hash described in MMS's API reference docs.

client = new MMS::Client.new('username', 'api_key')
host = MMS::Resource::Host.find(client, 'group_id', 'host_id')
metrics = host.metrics
options = {"granularity" => "HOUR", "period" => "P1DT12H" }
metrics.each do |m|
  puts m.data_points(options)
end

In case of hardware or database metrics, the return value will be an array that each value contains the data points for the relevant device or database.

Cli usage

There is a built-in cli with several commands retrieving api resource lists.

Configuration

Cli uses configuration with all values set to default ones. Config itself has config_file property which merges itself with params from the file. By default config_file points to home directory, but it can be changed to points to any file.

username=sysadmin@example.tld
apikey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
apiurl=https://mms.mydomain.tld/api/public/v1.0
default_group_id=your-group-id
default_cluster_id=your-cluster-id

Additionally some options can be modified using cli options.
