Extracting OID returned data

Question

I'm using a combination of APC Environmental Management modules AP9319, AP9340, AP9341 to return temperature and humidity data.

Both OIDs return 4 data elements, such as 0, 0, 0, 30.

How do I extract  say the second number from this string so that I can create a custom poller that triggers when it exceeds a preset number ?

Hi,

I would advise you to submit a support ticket so that one of the tech support could help you on this.

Sorry I'm trying to learn this as I go - "type the OID in a UnDP" What is the UnDP ?

UnDP => Universal Device Poller. Sorry about that I try to detail each abbreviation I use at least once in each thread but seems that I forgot in this one.

Thanks,

Yann

Hi Yann,

Thanks for your help - unfortunately the .2 doesn't work.

By a MIB walk do you mean browsing the MIB tree ? If so there are no index numbers shown.

Frustrated,

Hi,

Are you saying to add ".2" at the end of the oid string above to get the 2nd data element

Yes. so this means 1.3.6.1.4.1.318.1.1.10.3.13.1.1.3.2 for the temp and 1.3.6.1.4.1.318.1.1.10.3.13.1.1.6.2 for the humidity sensor.

It works for all the tables I tested it againsy, so I thought it would work as well on your table.

To ensure this works on your table, simply run a MIB walk (to see the full path + index number) or type the OID in a UnDP and select the following advanced options:

SNMP GET Type: GET

Polling Type: Node

Click on Next and test it on some nodes.

A comma (,2) would appear to be more likely.

I have never seen any comma in an OID path. OIDs path seems to be defined only with numbers and dots.

HTH,

Yann
