Data collection failed due to "Unknown" status of Data template.

Hello, community,

After a few months of using the new version of CACTI 1.2.27 (we updated from version 1.2.24), we have encountered an issue that is affecting our operations. Below are the configuration details:

• Some of the graphs monitored via SNMP queries defined on Data queries have stopped collecting data.

• In CACTI, we have defined a Data Template with various Output Type IDs for handling different types of data.

After these months of correct operation, it seems that some of the graphs have stopped displaying data. Upon analysing the issue, we noticed that the Output Data ID had been modified, so the parameters no longer matched, and as a result, the data was not being collected correctly for these graphs.

Investigating the possible cause, we found in the databases that these incorrect graphs were pointing to a Template ID that no longer existed, as it had been deleted. It seems that this template deletion was not done manually, so:

• Could it be possible that, for some reason, CACTI deleted this entry?

• Could this be due to the new version of CACTI or the update?

• What user-level actions on the web interface could lead to the deletion of this Output Data ID? And what about at the administrator level?

Thank you in advance. Best regards.
