Deploy or add existing standalone nodes, replicasets or shards.
Use the vendor of your choice; MongoDB Inc or Percona Server for MongoDB.
This blog post discusses how to deploy a Graylog cluster, with a MongoDB Replica Set deployed using ClusterControl.
MongoDB is great at storing clickstream data, but using it to analyze millions of documents can be challenging. Hadoop provides a way of processing and analyzing data at large scale. Since it is a parallel system, workloads can be split on multiple nodes and computations on large datasets can be done in relatively short timeframes. MongoDB data can be moved into Hadoop using ETL tools like Talend or Pentaho Data Integration (Kettle).
Replica Sets in MongoDB are very useful. They provide multiple copies of data, automated failover and read scalability. A Replica Set can consist of up to 12 nodes, with only one primary node (or master node) able to accept writes. In case of primary node failure, a new primary is auto-elected.Replica Sets in MongoDB are very useful. They provide multiple copies of data, automated failover and read scalability.

So, maybe you’ve been working with MySQL for a while and are now being asked to also properly maintain one or more MongoDB instances. It is not uncommon that MySQL DBAs, developers, network/system administrators or DevOps folks with general backgrounds, find themselves in this situation at some point in time. In fact, with more organisations operating polyglot environments, it’s starting to become commonplace.
To operate MongoDB efficiently, you need to have insight into database performance. And with that in mind, we’ll dive into monitoring in this second webinar in the ‘Become a MongoDB DBA’ series. MongoDB offers many metrics through various status overviews and commands, but which ones really matter to you? How do you trend and alert on them? What is the meaning behind the metrics?
