<![CDATA[Cannot read measurement unit information: Illegal repetition]]>I've been able to figure out how to poll a lot of information from SNMP, but as I'm trying to dump this into dashboards, I'm receiving the following error:

Cannot read measurement unit information: Illegal repetition near index 28
.1.3.6.1.4.1.41112.1.4.7.1.3.{instance}

Some google searching reveals that the java implementation of regex requires \\ before the { however with various attempts/changes and more searching, I'm not finding anything that works and doesn't break what I already have working 🙂

Since I don't quite know what I'm doing, I'm not sure if this is an issue with the script in Instance Discovery, or if there is a bug of some sort when building dashboards, that doesn't like an SNMP OID that references {instance}.

These fields will be renamed, e.g. "DCI name regular expression" to give more understanding.

Am I correct?   

Is there any way to define a DCI and then, also, tell it to ignore the last n characters of the OID based on the context?
