<![CDATA[DCI Database errors]]>I have a node with a DCI issue.

I am getting the error:

'Read DCI data from server' has encountered a problem.  Cannot get data for DCI "Node Name":[1464]: database failure

I noticed this as the data from the node was displaying on a dashboard and now just shows "Cannot get DCI Value..."

I have run a database check and all passed, I have deleted and recreated the DCI collection items with no success.

Please let me know what I can do to troubleshoot this.

Thank you.

Hi. After you delete and recreate dci items, you have to adjust dashboards, too. Because Your new DCISs' id numbers are different then older ones and dashboards save dci information as their ids. So, If you deleted and recreated any DCI that using by dashboard, you must adjust that dashboard (delete old dci info and add new ones).

mysqlcheck --auto-repair netxms -u root -p

Many entries were repaired...

started the NetXMS service:

the node with failures now allows charts... however they are blank for now, which I suppose should be expected.
