Monitor delegation - Fetching data fails or gets incomplete data set

[haraldfianbakken]

When invoking https://management.azure.com/providers/microsoft.insights/eventtypes/management/values?api-version=2015-04-01&`$filter=eventTimestamp ge '$($dateFormatForQuery)

you get in certain cases an empty result with a nextlink to fetch - or you get multiple pages with nextLink in response - so you need to iterate and fetch the result (fix coming)

Hi.

$list = Invoke-RestMethod @listOperations

Comment: First link can be empty - and point to a next link (or potentially multiple pages)
Comment: While you get more data - continue fetching and add result
while($list.nextLink){
$list2 = Invoke-RestMethod $list.nextLink -Headers $listOperations.Headers -Method Get
$data+=$list2.value;
$list.nextLink = $list2.nextlink;
}

$showOperations = $data;

$data does not get set if there is no value for $list.nextLink. Then the script does not work.

For the same tenant - if I set $showOperations = $list.value, I get an event as expected.

This works for me:
Comment: First link can be empty - and point to a next link (or potentially multiple pages)
Comment: While you get more data - continue fetching and add result

if ($null -ne $list.nextLink){
while($list.nextLink){
$list2 = Invoke-RestMethod $list.nextLink -Headers $listOperations.Headers -Method Get
$data+=$list2.value;
$list.nextLink = $list2.nextlink;
}
$showOperations = $data
}else{

Comment: Sometimes the first link is not empty.
$showOperations = $list.value

}
