Demo: Monitoring Your Cluster

By Lionel Gibbons | August 16, 2016

You've already seen how Bright Cluster Manager simplifies the tasks involved in deploying and managing a cluster. But there's even more to it than that.

Cluster monitoring vs. health checking: What’s the difference?

By c. brandis | March 11, 2015

If you are responsible for managing a cluster, you certainly use monitoring software to help you keep it running right. Many organizations, however, tend to lump cluster monitoring with cluster health checks, as if they were one and the same, interchangeable. They’re not.

One way to look at it is that cluster monitoring involves tracking and measuring data. Health checks show how well things are working (diagnostic).

Monitoring HPC Clusters: Is It Time for an Extreme Makeover?

By Ian Lumb | November 13, 2014

From the components that comprise a node (e.g., CPU cores plus accelerators and coprocessors, memory, disks), to the operating system and HPC software stack (e.g., client system for executing workload), device-specific metrics abound. As individual nodes communicate via interconnect fabrics (e.g., Ethernet, InfiniBand), metrics mushroom to reveal cluster-wide perspectives.

Everyone involved in running HPC clusters needs metrics. Hybrid-architecture, distributed systems, however, are a challenge to monitor, especially as systems scale out. Given the importance and inherent difficulties, it is not surprising that monitoring is once again topical in the HPC community. In fact, recent discussions are calling for an extreme makeover, by expressing the need to modernize monitoring for HPC clusters.

Bright Cluster Manager for Apache Hadoop: The First 6 Months of a Radiant Relationship

By Ian Lumb | September 26, 2014

Last week we released support for Apache Hadoop 2.5.0. I thought it would be a good time to revisit all the updates we’ve made over the last 6 months - in case you missed them.

Latest Updates

Our latest updates include:

  • Apache Hadoop 2.5.1  Typo? Not exactly. We introduced support for Apache Hadoop 2.5.0 last week. Since Version 2.5.1 (released on September 13, 2014) is a minor release that builds upon the stable 2.4.1 release, you can now expect support via YUM updates to Bright. Note that vanilla Apache Hadoop includes HDFS (the Hadoop Distributed File System), ZooKeeper (the coordination service) as well as YARN (the workload manager).
  • Cloudera CDH 5.1.0  We introduced support for CDH 5.1.0 in mid-July.
  • Hortonworks HDP 2.1  We introduced support for Hortonworks Data Platform (HDP) 2.1 in mid-May.

Bottom line: Bright Cluster Manager maintains support for all major distributions of Apache Hadoop. Because we’re obsessed with keeping you current, you don’t have to be. We free you up to focus on the analysis of Big Data - and wasn’t that why you got interested in Hadoop in the first place?
