New in This Release
MapR Monitoring in the EEP 4.0.0 release introduces the following enhancements:
- An upgraded component stack.
- A default security feature that secures the MapR cluster and supported ecosystem components, including MapR Monitoring, using MapR-SASL and wire-level encryption, as well as the ability to configure custom security.
- A Spyglass on Streams feature that uses Streams as the default mechanism through which
metrics flow from collectd to OpenTSDB.NOTE Writing to an external OpenTSDB is not supported from release 6.0 onwards.
- MapR Monitoring now provides metrics for the YARN Resource Manager and Node Manager.
Fixes
None
Known Issues and Limitations
Resolved Issues
- COLD-4: By default, collectd reads files from the custom configuration file directory (/opt/mapr/collectd/conf/) on nodes without support for the wordexp function, eliminating the need to include Filter "*.conf" in the collectd.conf configuration file.
- SPYG-838: On secure clusters, JMX ports can no longer be accessed without authentication, eliminating the need to setup a password on each Node Manager and Resource Manager node.
- KIB-1: A syntax error in export_cert.sh no longer causes an error message when you run configure.sh on a node with Kibana installed in a secure cluster.
