The Unravel 4.5 release, now generally available, builds on our previous 4.4 release with enhanced reporting, expanded SQL insights, and improved RESTful APIs.
Unravel 4.5 features new reports for “TopX”, queue analysis, cloud migration, and enhancements to the existing reports such as forecasts and chargeback.
[under Data Insights]
When you’re managing big data clusters, you have many ongoing operational and application challenges. Wouldn’t it be easier if you were notified daily/weekly/monthly about the top applications that you need to uncover-> understand->unravel?
Unravel’s TopX reports provide you with precisely this service. When you schedule a Top X report, Unravel generates a list of the top X (where 0 < X < 100) applications – whether they are Hive-on-MapReduce, Hive-on-Tez, or Spark – organized by categories, such as:
Within these reports, you can drill down into the APM view for each app, identify any inefficiencies and their root causes, and understand how to tune/optimize the app.
[Under Operational Insights]
Queue Analysisreports shine light on how you’re using queues and how you can tune them for optimal usage. These reports analyze queue activity with respect to applications, vcores, memory, and disk. As with all reports, you can generate Queue Analysis reports on an ad hoc or on a scheduled basis.
Unravel 4.5 also includes several new reports aimed at helping organizations move their big data workloads to the cloud (either onto an IaaS platform or onto a cloud native platform like AWS EMR, Azure HDInsight, etc.). These reports help organizations in planning -> migrating -> managing their big data workloads. Here’s a quick preview on these new reports
Cluster Discovery Report
Unravel provides a single pane of glass to display all of the relevant information e.g., services deployed, the topology of the cluster, cluster level stats (which have been suitably aggregated over the entire cluster’s resources) in terms of CPU, memory and disk. The across-cluster heatmaps display the relative utilization of the cluster across time (a 24×7 view for each hour of say a week).
Cloud Mapping Reports
Unravel provides you a mapping of your current on-prem environment to a cloud based one. Cloud Mapping Reports tell you the precise details of what type of cloud instances you would need, how many and what it would cost you. Here’s the mapping based on the strategy we refer to as “Cost Reduction” that provides you a one to one mapping of each existing on-prem host to the most suitable instance type in the cloud such that it matches the actual resource usage on-prem.
Stay tuned for new blogs on this topic in the coming weeks!
In addition to our new reports, we’ve enhanced our Forecasting, Chargeback, and Small Files reports for speed/performance and with support for additional frameworks (Impala, Tez) and platforms (MapR).
You spoke, we listened. A frequent request from customers has been to
As part of 4.5, Unravel now shows the progress (%) of individual jobs in a Spark app:
And, when you see a running YARN app (Spark, MR, and Tez) that’s taking far too much time (for issues related to data skew, slow nodes, etc.), you can now kill it or move it to a different YARN queue.
We continue to add more insights and recommendations for SQL engines like Tez and Impala. Some specific improvements for Hive/Tez apps include:
Some of the improvements for Impala include:
Unravel’s RESTful APIs provide an easy way to access the rich information collected and correlated by Unravel. Developers can access KPIs, metrics, alerts, etc. and integrate that data with other systems or tools already in use such as Slack, PagerDuty, Nagios, ServiceNow, etc.
As part of this release, we’ve made several enhancements to our existing API, including several new endpoints allowing you to:
Finally, I have highlighted just some of the key features in Unravel 4.5. This release also includes other updates like Auto Actions for Impala and Tez apps, support for SSO/SAML, security fixes, UI fixes, and many enhancements!
The Unravel 4.5 release is available on all supported platforms and works identically on-premises and in the cloud (Amazon AWS/EMR, Microsoft Azure, Google Cloud Platform).
