Known issues

Version 3.12.1 of Splunk DB Connect contains the following known issues. If no issues appear below, no issues have yet been reported.


Date filed Issue number Description
2023-05-26 DBX-5787 Inputs containing interval in a Non Standard cron expression cause failures

Workaround:
Splunk Modular Inputs only support Standard (Unix) cron expressions, as DB Connect does.

To fix the issue you can modify the cron expression for the affected Input in $SPLUNK_HOME/etc/apps/splunk_app_db_connect/local/inputs.conf and $SPLUNK_HOME/etc/apps/splunk_app_db_connect/local/db_inputs.conf, then restart Splunk.

You can also fix it by following the steps below:

  1. Disable the Input.
  2. Adjust Interval to be a Standard cron expression.
  3. Enable the Input.
2023-04-17 DBX-5788 Not allow to edit the description field in the Input configuration
2023-03-23 DBX-5766 Unable to write records java.net.SocketTimeoutException: Read timed out

Workaround:
Set dedicatedIoThreads = 8 in $SPLUNK_HOME/etc/system/local/inputs.conf

Allows the HEC to process multiple requests simultaneously, must not be greater than the number of CPU cores.

Set parallelIngestionPipelines = 2 in $SPLUNK_HOME/etc/system/local/server.conf

Multiple pipeline sets increase forwarder throughput and allow the forwarder to process multiple inputs simultaneously.

Set batch_upload_size = 500 in $SPLUNK_HOME/etc/apps/splunk_app_db_connect/local/db_inputs.conf

Number of rows to be uploaded to HEC in one batch.

Set maxHecContentLength = 5242880 in $SPLUNK_HOME/etc/apps/splunk_app_db_connect/local/dbx_settings.conf

Maximum size of each batch when uploading it to the HEC.

Note: A patch will be released with version 3.12.2.

2023-03-21 DBX-5765 Unable to set "org" parameter for connection with InfluxDB

Workaround:
Instead of using the dedicated "Org" field on the left side of the UI, use the JDBC URL text field next to it. Input the org parameter along with the proper value in that field.
