Capsule add-ons

Capsules are what we call our running containers at Compose. Add-on capsules are configured to provide extra services and can be set up immediately, most through the Compose UI. Read more about Compose capsules.

Meteor Router

Meteor speaks with the MongoDB oplog extensively. Typically sharded MongoDB deployments do not expose the oplog through the mongos router. In order to access the oplog, customers can use the Oplog Access addon which provides an HAproxy portal for you that can be configured to connect to the shard's primary node at a cost of $4.50/month per deployment.


Get more detailed log monitoring and analysis with our Syslog-ng add-on. Syslong-ng allows you to send a copy of your log files to Papertrail, Logentries and Loggly (more coming soon) to help you better understand how your databases are performing and how to optimize. The syslog-ng add-on capsule costs $9/month per deployment.


Telegraf is a package for collecting metrics from numerous sources and delivering them to one or more metric consuming systems. We currently offer configuration support for the DataDog performance monitoring platform. You'll need to create a Datadog account and that means you will also have to set up a single agent (that isn't Compose) to initialise the account. The Telegraf Add-on is priced at $9/month per deployment.


The Kibana visualization tool for Elasticsearch is a powerful way of turning your data into graphical expressions of trends and patterns. It offers a web interface which makes it easy to segment your data and then aggregate that data into meaningful information. The Kibana add-on for Compose is installed within your Compose cluster's private network and fronted by the same HAproxy access control that protects your Elasticsearch database. It means all your configured users get access to Kibana without installing anything locally. $6.50/month for 256MB.

Getting set up

  • Login to the Compose UI and select a deployed database
  • Select the tab on the left side labeled Add-ons
  • Add a new add-on capsule to the selected database, or re-configure whichever add-ons you've already added

What goes where

Each database offers different add-on capsules. Here's a handy chart that shows which capsules are available for which Compose databases.
