RRD with multiple DS-items and SNMP OID's

Hi,

I'm playing with 0.8 (pre-20030508) on FreeBSD and wonder how I should do following , IF possible offcourse ;

- I have 3 SNMP OID's

.1.3.6.1.4.1.529.26.1.4.1.8.8.43.45.51.51.51.52.48.48
.1.3.6.1.4.1.529.26.1.4.1.8.8.42.41.51.51.51.52.48.48
.1.3.6.1.4.1.529.26.1.4.1.8.8.41.49.51.51.51.52.48.48

I've created a new DATA Template and added multiple "DS" entries, in my hopes to accomodate the integer values returned from these queries.

However, I can only put 1 SNMP OID, altough I can create multiple DS
Why is that.

Yes, I could offcourse make 1 RRD per SNMP per device, but I was hoping I could "group" some SNMP OID's together and have them work and put the data in the RRD

I've taken a look at "Data Queries" but the problem is my SNMP OID's are not "walkeable", no indexed. I need this,that and that specific OID.
I've tried to edit the XML file but that does not seem to work...

Any clues if this is possible ?
Regards,
Jan

I have ran into similar situations as well, but have concluded each time that keeping one OID per data template keeps cacti's data model consistant.

The purpose of a data template is the abstract values common to some piece of retrievable data. Even though it may seem a little redundant at times, each OID represents a separate value and therefore should have its own fields.

Aside from my reasoning, this is definitely possible. You would probably end up having to create your own snmpget script though and it would have to expect or be fed the number of OIDs to process.

Like you noticed, data queries are not what you want for this task. My recommendation is to create a data template for each OID.

This means that if you create a rrd file with 2 DS you cannot assign a different OID's for each DS?
