What Operating System are you using (both controller, and any agents involved in the problem)?

Linux

Reproduction steps

Configure OpenTelemetry plugin to "Store pipeline logs In Elastic and visualize logs both in Elastic and through Jenkins"

Create any Jenkins Job that will do generate > 10kB of logs (logText in this example)

podTemplate(yaml: """
apiVersion: v1
kind: Pod
spec:
containers:
- name: ubuntu
  image: ubuntu:20.04
  tty: true
  command:
  - cat
""", showRawYaml: false) {
node(POD_LABEL) {
container('ubuntu') {
  timestamps {
    for (int run = 1; run < 1000; run++) {
      for (int line = 0; line < 50; line++) {
        println('xxxxxxxxxx----------xxxxxxxxxx----------xxxxxxxxxx----------xxxxxxxxxx----------xxxxxxxxxx----------')
      }
      println("Run: ${run}")
      sleep(1)
    }
  }
}
}
}

Navigate to the Console Output while the job is running ( https://jenkins/job/log-test/lastBuild/console)
Overserve what happens after run ~21, when the log becomes > 10 kB

Expected Results

The console log should continuously extend on the bottom of the log, line by line

Actual Results

If the log size exceeds > 10 kB, the log will not extend by the additional lies but extend by the complete log - from the begin of the run.

Anything else?

If you monitor the network traffic coming to your Browser (https://jenkins/job/log-test/lastBuild/logText/progressiveHtml) you will notice a change.

Until the complete log is < 10 kB, the data transferred will be ~1 kB

If the total log is > 10 kB, it will start to sending the complete log, starting from the start and not a "delta". By this, the live view will not be usable anymore due to it will continuously full.

If the job was finished, everything is back to normal - so only the live streaming of the log seems to have an issue with the total log of a total size greater than 10 kB

progressiveHtml if log < 10 kB: only delta

progressiveHtml if log > 10 kB: log from the begin of the job
