Packetbeat not starting after standby

I have packetbeat 6.1.2 installed as a service, running fine, but when I turn my laptop in standby (closing it) and I wake it up, packetbeat would not start.
I can start it manually.
And all 3 other beats that I installed the same way (audit, metric and winlog) are starting fine...
Thanks in advance for your help!

How can you tell packetbeat does not startup anymore?

Which operating system are you using?

I wonder if packetbeat actually starts, but can not sniff from device anymore. Might be a kernel issue... which device and sniffer type are you using?

Hi Steffen,
I'm running Windows 10 Pro (Version 10.0.16299 number 16299)
I know it doesn't run because when I check my services, it's "stopped". And I can start it again.
After running a few tests, it appears there is an error in windows events saying that the packetbeat service has stopped unexpectedly every time I close my laptop (goes in stand by mode).
Note that my packetbeat is configured to send data to a cluster I have on Elastic Cloud.

Have you checked packetbeat logs for errors? Please run packetbeat in debug mode. Debug selector 'service' should enough.

Can you run packetbeat on foreground, in terminal. In case packetbeat crashes/breaks after a sleep this info will be lost when being run as a service. For testing please run packetbeat in terminal with packetbeat.exe -e -v -d '*' -c <path/to/config/file>, but you machine to sleep and wake up after a while.

Here you go (i replaced my cloud id with xxx) :

Please format logs, configs and terminal input/output using the </>-Button or markdown code fences. This forum uses Markdown to format posts. Without proper formatting, it can be very hard to read your posts.

The last message indicates why packetbeat stops:

2018/02/09 16:14:14.883567 beat.go:635: CRIT Exiting: Sniffer main loop failed: Sniffing error: Read Error

It gets an Read Error from WinPCAP (just assuming you use WinPCAP) and there shuts down. I guess the network adapter is not yet ready, while packetbeat is trying to continue sniffing.

Sorry Steffens for the poor formatting
I solved my issue! indeed it was coming from winpcap
winpcap doesn't work on Windows 10
I used the win10pcap (see ) which is working fine!
Thanks for your support :slight_smile:
