Troubleshooting

Service does not exists

  • Verify that the csd is well present in /opt/cloudera/csd

  • Restart Cloudera Manager

  • Verify in its log: /var/log/cloudera-scm-server/cloudera-scm-server.log that DATAGEN CSD is well added and no errors pops up.

No metrics - Error Querying Internal

  • Restart Cloudera Management Service and especially Service Monitor.

  • You can also check that the local cloudera-agent is well running and able to capture metrics from Datagen Web server.

No Datagen status - Test has invalid configuration

It is possible that Service Monitor is not able to get some configuration values from Datagen.

  • Go to Datagen > Configuration and make following changes:

    unexpected_exits_thresholds to set Warning to Any and Critical to Never. process_swap_memory_thresholds to set Warning to Any and Critical to Never. process_swap_memory_rate_thresholds to set Warning to Any and Critical to Never. log_directory_free_space_percentage_thresholds to set Warning to 80 and Critical to 80.

  • Restart Cloudera Management Service.

  • The warning: Test disabled because of an invalid configuration: Test of whether enough DATAGEN_SERVER roles are healthy could be safely ignored and removed using suppress button.
