Resolutions for common issues

SymptomCauseResolution

The Cloudera ETL is not collecting data. The following message is reported in the Cloudera ETL log for each entity in the environment:

[2017-09-07 00:00:22] INFO Cloudera Extractor: Extracting HOST_PERF data for host hostname.domain.com
[2017-09-07 00:00:22] INFO Cloudera Extractor: Extracting data for [HOST_PERF:hostname.domain.com] since YYYYMM-
DD HH24:MI:SS Z
[2017-09-07 00:00:22] INFO Cloudera Extractor: empty time period, skipping query.


The Default Last Counter value is not correctly set in the ETL configuration

The setting might have a value of "YYYY-MM-DD HH24:MI:SS Z" when it should be set to an actual timestamp value, such as "2017-09-11 00:00:00".


The Cloudera ETL fails with BCO_ETL_ERR011 error or an error similar to the following:

[2019-11-20 10:08:58] INFO [SQLite Wrapper] Database file /opt/cpit/BCO/etl/temp/237-data/TO1LWWJ1.db
correctly deleted
[2019-11-20 10:08:58] WARNING [SQLite Wrapper] Database file delete failed since there is no such file or directory

This is a known issue with Cloudera ETL.Deploy the latest version of the Cloudera ETL from the Products Download section of the BMC Support portal.
