The Primary requests the information for each poller with pull requests. </p><p><span class="confluence-embedded-file-wrapper confluence-embedded-manual-size"><span class="confluence-embedded-file-wrapper confluence-embedded-manual-size"><img class="confluence-embedded-image" draggable="false" height="400" src="https://community.opmantek.com/download/attachments/132546786/Screen%20Shot%202021-04-08%20at%207.33.06%20am.png?version=1&modificationDate=1710131444000&api=v2" data-image-src="https://community.opmantek.com/download/attachments/132546786/Screen%20Shot%202021-04-08%20at%207.33.06%20am.png?version=1&modificationDate=1710131444000&api=v2" data-unresolved-comment-count="0" data-linked-resource-id="132546787" data-linked-resource-version="1" data-linked-resource-type="attachment" data-linked-resource-default-alias="Screen Shot 2021-04-08 at 7.33.06 am.png" data-base-url="https://community.opmantek.com" data-linked-resource-content-type="image/png" data-linked-resource-container-id="132546786" data-linked-resource-container-version="4" alt=""></span></span></p><p>The first time the pull script runs, it requests all the data for each configured poller.
