Unstable using latest from 0.13-dev branch

[StevenACoffman]

I am experiencing a lot of instability when applying the latest changes from 0.13-dev branch, specifically #16

Eventually if a pod crashes on a busy nodes and enters CrashLoopBackOff, it won't ever recover. I am still investigating, but if you can see anything obvious, I would really appreciate your insight.

At first, I thought it was the memory and or cpu limits, so I removed those and crashes happen much less reliably. Without limits, I'm still seeing what looks like multiple failure reasons. I changed the namespace (to kangaroo) and kafka topic (to k8s-firehose), and I changed the Log_Level to debug. In the Kube_URL, kubernetes.default.svc got a few Temporary failure in name resolution errors so I changed it to kubernetes.default.svc.cluster.local and it have not seen it again.

I am using kail to follow all the daemonset pods in parallel, but that's quite chatty, so I do filter it down to errors with some context using:

kail --ds=fluent-bit | grep -A 10 -B 10 error

The output I get is:

[edsiper]

do you know if is there any best practice about using a DNS name to reach the API server ? filter_kubernetes by default uses kubernetes.default.svc, but what about kubernetes.default.svc.cluster.local ? (cc: @solsson)

[solsson]

I've seen a lot of both [service].[namespace] as well as names ending with .svc.cluster.local but rarely names ending with .svc. https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#a-records seems to recommend the full name. I don't know if there's specific conventions for Kubernetes API access.

[edsiper]

thanks for the feedback, I will go ahead and change that.

[edsiper]

@StevenACoffman is this still an issue ?

[StevenACoffman]

@edsiper You mentioned a lack of "check" in out_kafka in #18

The instability I'm seeing seems completely attributable due to the memory (and cpu?) limits for nodes with lots of pre-existing logs.

From @solsson on Jan 26, 2018:

Spikes in memory use at pod start are impractical. Can log processing be halted when kafka buffers hit a size limit? Would it be possible to add output buffer size to prometheus metrics?

From @leahnp on May 17, 2017 0:6

Add memory limit to deployment yaml. Test special case: in long-running clusters with lots of pre-existing logs, deploy Fluent-bit, initial workload is very heavy then it evens out. If it hits the memory limit in this initial processing it will continually be killed and re-created.

Copied from original issue: samsung-cnct/kraken-logging-fluent-bit-daemonset#5 and Moved to samsung-cnct/chart-fluent-bit#9

[solsson]

@edsiper I think you can merge #18 as further increases in limit would make no difference. Only caps to buffer sizes will.

What's the effect of Mem_Buf_Limit on the input plugin at start? Desired behavior of Tail would be that parsing stops temporarily. According to http://fluentbit.io/documentation/0.12/configuration/backpressure.html#membuflimit it can be set on output plugins too, but am I correct to interpret your earlier remarks as this having no effect because the kafka client does the buffering? Maybe fluent/fluent-bit#495 can help for a cap there, through queued.max.messages.kbytes etc.

[edsiper]

@solsson merged, thanks.

Mem_Buf_Limit only applies for input plugins to pause data ingestion into the engine. Since out_kafka buffer the data (not delivery), Fluent Bit issue a "OK", so in_tail keeps ingesting data. The fix is to add out_kafka logic to real check if a message was delivered.

If you see memory grow with a different output plugin, there is definitely something wrong, I will double check the code anyways

[solsson]

I'm only running out_kafka. I will try out_kafka with queue.buffering.max.kbytes after the 0.13 release. The default seems to be 1GB, so with fluent/fluent-bit#495 I can set it to something like 10MB instead. The docs say "Maximum total message size sum allowed on the producer queue." and allowed indicates that out_kafka would be notified when the max is reached.

Hmm... I pulled from the latest, removed the cpu and memory limits, and I'm getting some CrashLoopBackOff Pods terminated with exitCode 139, which I think is a Segmentation Fault (SIGSEGV 11). No termination message. This is not on a node with excessive existing logs.
The logs from fluent-bit look entirely normal. I tried changing the Log_Level to debug and deleted the old pod, when the new one gets created it logs normal debug messages:

Earlier in fluent-bit pod's output, I am getting a lot of:

[2018/01/30 22:26:08] [debug] [filter_kube] could not merge log as requested

I cannot seem to have the pod on that node come up healthy, regardless of restarts or terminate and re-create attempts, but the rest do.

I altered the configmap and changed the filter-kubernetes.conf to:

        Merge_Log           Off
        K8S-Logging.Parser  Off

Applying the change, deleting the pod, the daemonset recreated the pod and it came up healthy after several hours of other failed attempts.
