8.2.3 Agent unhealthy, when "Network Packet Capture" integration is enabled in agent policy

buzzdeee · June 16, 2022, 11:27am

I created a elastic cloud trial instance yesterday, but my Windows client is unhealthy.
elastic-agent status output shows:

diagnostics actually looks good, but I wonder about the endpoint-security error message.

Anyone knows what's going on?

On a Linux client it looked a little different, but then I removed the "Network Packet Capture" integration from the policies, and they all three became healthy.

Seems to be something odd with that integration.

TiagoQueiroz · June 17, 2022, 9:27am

Indeed it's a problem with the "Network Packet Capture" integration, more specifically with its Redis capture.

If you want to use the integration, just disable the Redis capture, to do so go to the integration settings, then on "Capture network traffic" click on "Change defaults", scroll down until you find "Redis", then turn it off.

That should solve the problem and make Filebeat start.

I'll report the bug.

buzzdeee · June 17, 2022, 3:09pm

Hi @TiagoQueiroz

thanks for your reply, that helped.
In my testing, I enabled everything, even though I don't need all.
With only the pieces enabled that I need, agents are healthy.

cheers,
Sebastian

It's a problem with the way Agent generates the config for Filebeat. The Agent misidentifies the redis config as something that belongs to Filebeat instead of Packetbeat.

github.com/elastic/elastic-agent

Filebeat spec is incorporating Packetbeat inputs into its config

bug Team:Elastic-Agent-Data-Plane 8.5-candidate

When an agent policy contains the Packetbeat redis input, Elastic Agent is gener…ating config for Filebeat that includes a redis log input. The policy for Packetbeat uses input `type: packet` with a data_stream of `type: redis`. For example: ```yaml # agent policy inputs: - type: packet streams: - data_stream: dataset: network_traffic.redis type: logs type: redis ports: - 6379 ``` The impact is that this causes Filebeat to report UNHEALTHY status if Packetbeat is deployed at the same time. A workaround is to disable redis collection in the Network Packet Capture integration. Here is a patch to the Elastic Agent testdata that reproduces the bug using unit tests: <details> ```diff diff --git a/internal/pkg/agent/program/testdata/single_config-packetbeat.yml b/internal/pkg/agent/program/testdata/single_config-packetbeat.yml index f800d0bd2..4ea37b1fb 100644 --- a/internal/pkg/agent/program/testdata/single_config-packetbeat.yml +++ b/internal/pkg/agent/program/testdata/single_config-packetbeat.yml @@ -23,6 +23,13 @@ inputs: data_stream: dataset: packet.icmp type: logs + - data_stream: + dataset: network_traffic.redis + type: logs + id: packet-network_traffic.redis-387bdc6a-0acb-4ef2-9552-c21e524a2d21 + ports: + - 6379 + type: redis output: elasticsearch: hosts: diff --git a/internal/pkg/agent/program/testdata/single_config.yml b/internal/pkg/agent/program/testdata/single_config.yml index 16a03f9a7..140a61f79 100644 --- a/internal/pkg/agent/program/testdata/single_config.yml +++ b/internal/pkg/agent/program/testdata/single_config.yml @@ -104,6 +104,13 @@ inputs: data_stream: dataset: packet.icmp type: logs + - data_stream: + dataset: network_traffic.redis + type: logs + id: packet-network_traffic.redis-387bdc6a-0acb-4ef2-9552-c21e524a2d21 + ports: + - 6379 + type: redis - id: endpoint-id type: endpoint name: endpoint-1 ``` </details> ### Workarounds You can disable the redis protocol in the network packet capture integration. <img width="717" alt="Screen Shot 2022-05-13 at 18 41 58" src="https://user-images.githubusercontent.com/4565752/168398092-a23997f5-9723-448e-b7b0-9fee64ca8195.png"> <img width="715" alt="Screen Shot 2022-05-13 at 18 42 12" src="https://user-images.githubusercontent.com/4565752/168398099-0e8b16c0-685e-41b6-87e1-017956a1fb17.png">
