ObjectRocket has created a couple of example tools to use in conjunction with the ObjectRocket service. The ObjectRocket API makes it very easy to query the service for data and metadata for various things like monitoring or performance tools.
Rocketstat is a clone of the popular mongostat utility. This utility show various performance metrics about the ObjectRocket instance. Note the data is an aggregation of all shards. It runs on the command line, and probes the ObjectRocket API for data every N seconds and reports the performance data on the command line. It is actually based on the original python implementation of mongostat from 2009. Licensed under the Apache License, Version 2.0.
RocketTop is a real-time statistics viewer for ObjectRocket. It runs on the command line and probes the ObjectRocket API for real time session data every N seconds and displays the results similarly to the Unix "top" utility. Licensed under the Apache License, Version 2.0.
