Log Aggregation
- Matthew Girard
CloudWatch
Logs across all Denodo servers are aggregated into Amazon CloudWatch using the CloudWatch Agent.
Logs can be viewed here.
Logs prior to 2023-10-06 can be accessed in the DLT account. Logs from that date and after can be found the LZ Dev account. Logs can be accessed in those accounts using the same link.
Logs for production systems (solution manager and VDP) after 2023-12-11 need to be accessed from the LZ Prod account.
Logs are grouped by file into log groups starting with the prefix /denodo/. After the /denodo/ prefix comes the server type prefix (such as /vdp/ or /solution-manager/), followed by the log type.
Within each log group is a stream with a name that represents where the stream is coming from (such as denodo-dev-01.it.tufts.edu).
When viewing logs, be sure that your log viewer is set to show columns and details. Don’t select View in plain text, since this will keep you from properly filtering on the timestamp.
