Heavy forwarder can't reach some cloud sources

[Gursimar_singh]

We have a HF which was configured to pull data from various sources, but it stopped receiving data suddenly from a few sources. How can I troubleshoot this issue?

Hi

you are probably sending it's internal logs to splunk? If yes, then you could search those vis GUI and try to find when and why it has stopped. Usually you could found those with queries like

index=_internal host=<your hf> source=*/<your log sources under $SPLUNK_HOME/var/log/splunk/<your log name>>

Otherwise just log to your HF and look those logs on cmd line.
