Logs are cut off in dashboard UI

[bartoliniii]

Logs presented in web UI are always cut off and there is no way to find the reason for the failure from this view.
In jx get build logs logs are present correctly.

Sample URL address for this view - https://dashboard-jx.jenkinsx.company/org/repot/master/XXX
Pipelines visualizer version: 1.7.5

Described situation is illustrated below. On the left you can see all logs from a pod, on the right you can see that in dashbord there are a few last lines missing. I have this issue for every failing build.

more details would help

I haven't seen this

Is there an error?

[keskad]

Could you post any screenshots to show how it looks like? Any logs from browser's inspector while viewing this view? Server responses from inspector? 🙂

@keskad @patrickleet I've just attached a screenshot to the issue description.

In network traffic, I see that dashboard is presenting everything that gets from the server:

I'm not sure if it is connected with this issue, but sometimes I get the below between log lines:

failed to create fsnotify watcher: too many open files

[patrickleet]

failed to create fsnotify watcher: too many open files

is an error with how your kubernetes nodes are configured.

see kubernetes/kubernetes#64315 (comment)

FWIW, I've only seen this happen with worker groups, not managed node groups - I think defaults for managed node groups are better

@patrickleet I've changed the node configuration, now I don't see an error with "open files" anymore.

Unfortunately original issue, with cut off logs, still occurs.
It looks like a general error with sending data from a server. Isn't this kind of problem that occurs for each user?

[patrickleet]

I didn't make the ui but maybe something to do with stdout vs stderr?

I am also experiencing the same.

example pipeline step:

- name: db-wait
          image: docker.io/amazon/aws-cli:2.0.52
          script: |
            #!/bin/sh
            source .jx/variables.sh
            echo ">>> Found PR #$PULL_NUMBER"

sometimes it will show the echo output, sometimes it wont.
if i have multiple lines that use echo, some will show, others will not
