Update Filebeat Traefik module to handle mixed Common and Combined Log Format #8768

sayden · 2018-10-26T15:23:58Z

This is a continuation of PRs #6488 and #6136

Previous PR's were misleading because there's no difference between Traefik 1.5 and 1.7 log formats but as you can see in this issue Traefik could miss some quote which would make our parser to fail. So those PR's were to address that issue.

Traefik uses by default since 1.4 version (at least) the Combined Log Format https://httpd.apache.org/docs/trunk/logs.html#combined also used in Apache. In 1.7 it still uses this format but you can also setup Common Log Format or JSON. Maybe we should open an issue to support JSON in the future.

Solves #8015 and #6111

frontend_name field was added so Traefik frontend_name is missing #8015 is solved.
The Grok pattern have been improved to handle the case of Traefik module for Filebeat is not working as expected #6111 and the log lines described there have been added to the test cases successfully so the issue is also solved.
Added user_identifier field which was hardcoded to '-' before
Added duration field which was missing too
Added request_count field
Numeric fields added as string have been converted to long like response_code

GeoIP plugin error, as usual

ruflin · 2018-10-29T07:56:03Z

The geoip problem should be solve for quite some time now. Make sure to run the most recent master version locally and run the test command with GENERATE=1.

For the IP address: I would prefer to keep the "original" IP addresses instead of defaulting to 1.2.3.4 in this PR.

ruflin · 2018-10-29T07:57:17Z

Can you add a CHANGELOG entry?

I also added the needs_backport label. I'm thinking we should backport this to 6.x and potentially event 6.5. @jsoriano WDYT?

jsoriano · 2018-10-29T11:55:43Z

@ruflin it'd be great if it could make it to 6.5, yes

sayden · 2018-10-29T21:38:26Z

@ruflin about the 1.7 format that you mention here. Do you think it should be added to this PR already or we open a new one once this is merged?

ruflin · 2018-10-30T06:32:37Z

@sayden Let's keep this focused on 1.5 for now and follow up on 1.7 afterwards. Let me know if you need help with the generated data.

jsoriano · 2018-11-27T10:23:05Z

This seems to need an update.

sayden · 2018-11-27T12:34:48Z

Apart from the fields.go file, I'm carefully looking at the rebase as there were some updated in the expected JSON, I think coming from the ECS migration

ruflin · 2018-11-27T13:37:24Z

This will soon conflict with this PR. @webmat for awareness: #9005 I would suggest to get this one in and then ECS to make sure we cover all the fields but please coordinate together.

webmat · 2018-11-27T14:32:01Z

The race is on, to merge first! ;-)

Kidding, I don't mind if this gets in first. Looks like this PR needs a rebase, and has test failures, though.

I can keep my Traefik PR for last to give this time to get in, but note that I'd like to merge mine today.

@sayden did you expect to be finishing this up today?

sayden · 2018-11-27T17:26:11Z

@webmat If you want and you are close to finish just go on and I'll resolve conflicts later. I prefer to be careful with small details and take my time 👍

webmat · 2018-11-27T18:09:36Z

Perfect.

Note I may not get to my own Traefik PR today, as I need to work on something else before this.

        {
-            "rename": {
+            "remove": {


What is the reason we remove this one now?

After spending some minutes looking at it without understanding very well why either, I think that in a first look it made me think that it was a typo, because the field is set in the previous rule. Then, in a second look (maybe I couple of days later) I probably saw the "target_field": "traefik.access.user_agent.original" and I also thought it was some kind of typo that shouldn't be there and I delete it.

I guess that the approach here would be to not leave it again as a rename to preserve the original user_agent extracted from the Grok pattern, right?

Yes, please keep this field around

I see we add 2 new grok patterns: How are they different? Below we only add 1 new log line to test. Would be good to have at least 1 for each new pattern.

Yes, I also think so. I'll add a new input test line.

sayden · 2018-11-30T11:58:55Z

After digging deeply into this issue I discovered that there's nothing like Traefik logs format but that they have always used CLF - Common Log Format or Combined Log Format.

The problem is that Traefik had a bug prior 1.5 where if the request_referrer field was empty it didn't match the requirements of CLF because quotes were missing. Fix is merged here.

Current version of Traefik (1.7) uses Combined Log Format as default output format.

I suggest to leave the pattern with Combined Log Format to "force" Traefik users to update. It doesn't make sense that we have a modified Grok pattern just to cover some bug in a different product that we will have track to eventually delete it. Option 2 is to try to cover both: combined and common log format although it seems that Common is not used in Traefik right now.

WDYT @ruflin?

@sayden I suggest we follow up this PR with moving the dissect processing to the ingest pipeline. It should still be dissect as it's more efficient but like this we have everything in one place if we want to do reprocessing for example. We can do this change for 7.0 but not backport it.
