Custom error message with IMAP sensor.



Hello, we are using the IMAP sensor to indirectly monitor some Synology NASs. You can't get the information if there are false sectors on a disk via SNMP but the DSM can send mails. We can filter the mails to our needs but we would like to see which disk on which Synology has false sectors. Is there a way to copy text from the content of mails into the error message?

Regards, Marco Riechen

Hi Marco,

I appreciate your contact.

Per default, it is not possible to extract parts of the mail context to show up as sensor message. Maybe, a custom sensor might help to query the Synology API and provide that information, but this is just a shot in the dark.

Best regards,

Hi Sebastian,

Thank you for your reply, unfortunately that is what i thought. I will try to write a custom sensor. Best regards, Marco
