Resolve problems faster and gain end-to-end visibility across your Hadoop® environment
Splunk® App for HadoopOps
F a c t S h e e t
enter SplunkThe Splunk App for HadoopOps meets this challenge with a single interface to search, monitor and analyze the full Hadoop environment including cluster resources beyond Hadoop itself, such as the network, switch, rack, operating system and database.
The Splunk App provides end-to-end visibility and lets you perform rapid troubleshooting and analysis across your Hadoop environment. Search, monitor, alert, troubleshoot and analyze Hadoop nodes, Hadoop distributed file systems (HDFS), MapReduce jobs and more.
Features and BenefitsThe Splunk App for HadoopOps provides a number of specialized features that help you monitor Hadoop:
Monitor Nodes on Cluster – Get a complete view of all the servers in the cluster. See the health of the cluster, track hard disk, CPU and RAM utilization from a single view. Cluster visualization display the rack or node where a specific failure might occur
Troubleshoot MapReduce Jobs – Gain real-time and historical statistics on the individual and combined Map and Reduce tasks. Troubleshoot MapReduce performance issues by comparing similar jobs and comparing JobIDs to TaskIDs. Correlate between the used core slots and MapReduce tasks and pinpoint the MapReduce attempts that are using them.
Monitor Hadoop Services – Expose Hadoop metrics and view the health of the Hadoop file system daemons. Monitor the key load, capacity and resource metrics for enabling hardware and software capacity planning.
Manage Services – Enable Hadoop administrators to establish specific views of nodes so they can monitor only the nodes need to see. For example, an administrator can choose to view only the production nodes within a cluster
challenge of Monitoring hadoop environmentsMonitoring Hadoop deployments is a complex and time-consuming function. Existing Hadoop monitoring tools are designed solely to monitor the Hadoop environment—with a lack of visibility into the network, switch, OS and other supporting infrastructure administrators are faced with a significant visibility gap. Without an end-to-end view, critical problems impacting the Hadoop environment will often reoccur and remain unresolved.
• Real-time operational health and performance monitoring of entire Hadoop environment
• Integrated alerting to track and respond to activities from MapReduce to the individual node in the cluster
• A centralized real-time view of Hadoop nodes using an intuitive heat map display

View Hadoop Configurations – Discover the configuration of each node and each daemon in the Hadoop cluster. Hadoop is highly dependent on the hardware and network it uses. Monitor for any changes made to the Hadoop configurations to help prevent service disruptions. Drive faster resolution times by using Splunk software to view configurations from HDFS, MapReduce and the entire surrounding environment.
Search Logs – Enhance end-to-end debugging of issues with the power of Splunk search and real-time display of information from all Hadoop, Linux, database and network log files. See at- a-glance health status, cluster visualization, job performance and analysis through a powerful, interactive user interface. The App data model includes hundreds of specialized event types, source types and field definitions to help you build new dashboards and generate reports quickly.
Set Headline and Alert Notifications – Create alerts that are triggered on a single event as well as on a correlated group of events. Per-result alerting provides granular control over the notifications received when a Hadoop node, MapReduce task or HDFS daemon is failing.
