I am trying to install "Splunk add-on for new relic" on splunkcloud instance, but i am not able to find any option to install. Can anyone share steps or document if any, that can help?
Or any alternate, we need to integrate new relic data to splunk.
According to splunkbase, that add-on is not compatible with Splunk Cloud. It's possible the add-on just hasn't been validated for Splunk Cloud so you may want to consider submitting a Support request to have them install it. They will confirm if the add-on can be installed in Splunk Cloud.
If the add-on cannot be installed in Splunk Cloud then you can install it on an on-prem heavy forwarder that sends the collected data to Cloud indexers.
