Hi Michael,
Further to Silvio's response, eHealth and Spectrum poll the devices separately and so have their own polling mechanisms independent of each other. What the integration does is synchronise the discovered devices between the two so that:
- alarms can be forwarded from eHealth (via Live Exceptions) when raised against any particular element to Spectrum where it will be asserted against the correspondingly mapped model.
- You can also run certain eHealth functions (such as performance reports) from the Spectrum OneClick client console as the integration pulls the polled data from eHealth to Spectrum.
You can read up on the full scope of the integration here:
eHealth and CA Spectrum - CA Spectrum - 10.2 to 10.2.3 - CA Technologies Documentation
Please be advised though that eHealth will be End of Support (EOS) on 1st May 2018, so neither it, nor the integration with Spectrum will be supported after this date:
CA eHealth End of Life Announcement
So we recommend you look at transitioning to the more capable CA Performance Management (current release 3.5) which not only integrates with Spectrum but also is SNMPv3 capable out of the box.
