I was wondering if it's somehow possible to combine the results of several pollers. For instance the combined bandwidth usage of ports (not what I need it for) - can the new transforms somehow be used for this ?
Just create a transform and add all your pollers together:
{poller1}+{poller2}+{poller3}+etc...
Keep in mind that if you're polling for bandwidth, the counters are 'octets', which means they are in bytes, not bits. In order to get bits, you need to divide by 8, so your final transform should look like this:
{poller1}+{poller2}+{poller3}/8
or
({poller1}/8)+({poller2}/8)+({poller3}/8)
Sorry, that should be:
({poller1}+{poller2}+{poller3})/8
One clarification: you can combine poller results in this way, just like bleearg13 demonstrated, but only from pollers that are assigned to the same network object. You can't combine results for pollers assigned to two different nodes, for example.
