Fixes

Principal fixes in this release include:
  • ES-20: Elastic Search Key management seems unnecessarily complex. For more information, see "Simplified Installation for Log Monitoring" in Installation Notes (Release 7.6.1).
  • COLD-168: Collectd process leak memory.
  • GRAF-57: Grafana: SSRF Incorrect access control vulnerability (CVE-2020-13379).

Known Issues and Limitations

This release contains the following known issues and limitations:
  • COLD-162: Graphs in the Control System do not display metrics for file system operations when hostname aliases are used. Workaround: Use fully qualified domain names when you install the Data Fabric through the Installer. Run hostname -f to verify that the fully qualified domain name is returned. If the command returns a short hostname, the issue will persist.
  • ES-77: During an upgrade from EEP 6.x to EEP 7.0.0 or EEP 7.0.1, some monitoring components do not get updated because of an error in the fourth digit of the package version. This issue can occur during manual upgrades or upgrades performed using the Installer. The affected components can include any or all of the following:
    • Elasticsearch
    • Fluentd
    • Grafana
    • Kibana
    Workaround: See Reinstalling Monitoring Components After an Upgrade.
  • FLUD-51: In the fluentd.conf file, the log file name for Kibana is kibana.log. The file name is incorrect; the file name should be kibana_daemon.log. As long as the fluentd.conf file has the incorrect log-file name, you will not see Kibana log entries in Elasticsearch. Workaround: In the fluentd.conf file, change kibana.log to kibana_daemon.log, and restart Fluentd.
  • KIB-45: The Kibana default index and example dashboard are not loaded at system startup. Workaround: Run the following command, and restart Fluentd:
    chmod +x /opt/mapr/kibana/kibana-6.8.8/bin/es_mgmt.sh

Resolved Issues

  • None.
