Add_docker_metadata not working with match_source: false

pa.cloud · June 21, 2018, 1:24pm

Hi,

Though I could successfully use add_docker_metadata with "~" as well as if I set match_source: true

But i am unable to get it to work if i set match_source: false. Please see my config below.
Not sure if it's because of the "fields" in match_fields/match_pids, though i've tried with some other fields as well..it more looks like at runtime the value of the fields is not found. Although I see no clue in logs (even debug level)

============================

filebeat.prospectors:

- type: docker

  enabled: true
  containers:
    path: /var/lib/docker/containers
    ids: "*"
  processors:
    - add_docker_metadata:
        host: "unix:///var/run/docker.sock"
        match_fields: ["system.process.cgroup.id"]
        match_pids: ["process.pid", "process.ppid"]
        match_source: false
        match_source_index: 4
        match_short_id: true

====================================

I've tried this with filebeat 6.2.4 as well as 6.3
Tried both with

type: log and
type: docker

Any help/pointer is appreciated.

TIA

Could you please format your config using </>? Also, please attach the debug logs.

pa.cloud · June 21, 2018, 2:02pm

Please find logs below. Fwiw, i changed the config to monitor just my container "9010..", instead of ids: "*"

Just to add, i couldn't spot any difference in logs for success/failure case.
Just changing the "match_source: " to true in mentioned config emits the metadata.

Also, I noticed the fields of my container map. Should it contain the fields specified in match_fields/match_pids to work without match_source ?

Hi, kvch,
I have provided debug logs. Would really appreciate if I can get some pointer.

I feel it's because of fields not being present in the container map. Can anyone guide what needs to be done to get them in map:

match_fields: ["system.process.cgroup.id"]
match_pids: ["process.pid", "process.ppid"]

I don't see them in map...

map[service.name:myservice service.version:docktest execID:84ad266925ba5a8fbb5a3f325dd1cfe39bb873a8920281eed66016d4ebf74f82

TIA

kvch · June 25, 2018, 3:34pm

If you disable match_source, log paths are not matching. Thus, events are not going to be enriched.
sytem.process.cgroup.id, process.pid and process.ppid fields are not present in Filebeat events by default. It's provided by Metricbeat automaticcaly. You need to add those fields to your event manually in case of Filebeat.

What is it that you are trying to achieve by disabling this option?

pa.cloud · June 25, 2018, 4:41pm

Thanks for replying.
Can you please guide me how to add those fields. Is there any link/documentation that i can refer to?

I want to log to custom location (volume)...so my log path would not have container id.

pa.cloud · June 27, 2018, 11:09am

Hi,
Can anyone please let me know how can I get additional fields (process.pid, process.ppid or any other which can enable enriching of logs with docker metadata.

I tried include_fields: and fields: but it didn't work

- type: docker

  fields: #      =====> DOESN'T SEEM TO HELP
    docker: true
    system: true
    auditd: true

  enabled: true
  containers:
    path: /var/lib/docker/containers
    ids: "*"
  processors:
    - include_fields:  #    ====> DOESN'T SEEM TO HELP
        fields: ["docker.container.id", "process.pid", "process.ppid"]
    - add_docker_metadata:
        host: "unix:///var/run/docker.sock"
        match_fields: ["docker.container.id", "system.process.cgroup.id"]
        match_pids: ["process.pid", "process.ppid"]
        match_source: false
        match_source_index: 4
        match_short_id: false

By manually I meant that Filebeat does not support this unfortunately.
