fluentd-ui's Issues

Create "Add Data Output" Button

Create "Add Data Output" button, to add data source to running Fluentd. The candidates for data sources are:

Treasure Data
S3
MongoDB
Forward

(Please add possible data output cc: @repeatedly)

Auto update fluentd-ui by itself

fluentd-ui is a gem, so update info is available on rubygems.org
e.g. Rails
https://rubygems.org/gems/rails/versions.atom

Evaluate fluentd-server as something we want to incorporate

https://github.com/sonots/fluentd-server

While @sonots's fluentd-server is not strictly about UI, it does help with deploying/managing Fluentd configs.

This is a placeholder issue for us to discuss whether we want to incorporate fluentd-server into fluentd-ui.

Prepare spec/rails_helper.rb for RSpec 3

Because some files created by rails g require 'spec/rails_helper.rb' but it doesn't exist.

zombie process is increased

I use fluend-ui

Started with the following command:

[root@localhost ~]# fluentd-ui start

When the fluentd start in Dashbard web,
zombie process is increased.

[root@localhost ~]# ps aux | grep ruby

root 5541 8.2 0.0 0 0 pts/1 Z+ 14:22 0:00 [ruby]
root 5541 1.0 0.0 0 0 pts/1 Z+ 14:22 0:00 [ruby]
root 5593 2.7 0.0 0 0 pts/1 Z+ 14:23 0:00 [ruby]

Please let me know the reason why it occurs.

Inject several values via environment variables.

To overwrite some values, like FLUENT_PLUGIN.

We can set title and other names with same approach. Fluentd UI to Treasure Agent UI

Change Password To Default

Hi Guys,
i'm pretty new to ruby, and i got stuck at fluend-ui because i forgot my password ( i've change it from 'changeme' ) and my question is how do i reset the fluentd-ui password to default ?

Unable to input any words in regex text box at Select File Format

Problem Description

When I use Select File Format, fluentd-ui was caused the issue like the following image.
And, I can't type any words in text box.

Environments

ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-darwin14.0]
fluentd 0.10.59
fluentd-ui 0.3.12

Reproduce steps

Select "Select File Format"
Select regep as format
Type words quickly in regexp text box

Setting up fluentd does not create parent directories

When I set pid file path to /Users/frsyuki/test/fluentd/var/run/fluentd.pid, fluentd-ui doesn't create /Users/frsyuki/test/fluentd/var/run directory.

Rails 4.2 compatability

Is anyone working on this right now?

Thanks,

Unable to start fluentd on vagrant box

Not exactly an issue,but I am not a ruby rails person and did not find any docmentation on getting this to work.

I have setup fluentd on scotch box vagrant image and installed the required dependencies.
After doing

vagrant@scotchbox:/var/www/fluentd-ui$ bundle exec rails s
=> Booting Puma
=> Rails 4.2.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Puma 2.11.1 starting...
* Min threads: 0, max threads: 16
* Environment: development
* Listening on tcp://localhost:3000

I have setup fluentd-ui in my project directory which is under /var/www/.My structure is

  /var/www/
         |
         |__fluentd-ui (alongwith my -app directories)
                 |
                 |__all fluentd ui related files

I tried to access it via ip address using 192.168.10.33/fluentd-ui/ did not work 192.168.10.33:3000 even this did not work. port 9900 (thought this is default) did not work.
I believe I have configured it correctly,but how am I supposed to access it via the browser?

Make auto-reload by default

I believe most of the people want auto-reloading here by default. > http://localhost:3000/fluentd

Installation redirects are taking a long time

Running the recommended
gem install -V fluentd-ui
is triggering a cascading series of
302 Temporarily Moved
redirects which are taking a huge amount of time compared to the installation itself. It does eventually complete but it would be useful to get this fixed (or looked at, at the very least).

refactor around config history handling

Change URL from /fluentd to /daemon or /server

Change URL from /fluentd to /daemon or /server.

Admin UI template selection

Please select admin UI template.

Got gem dependency error

I Installing fluentd-ui on Amazon Linux(Amazon Linux AMI release 2014.03 / ruby 2.0.0p451 (2014-02-24 revision 45167) [x86_64-linux]).

sudo yum install gcc gcc-c++ openssl-devel ruby-devel.noarch patch
sudo gem install fluentd-ui --no-ri --no-rdoc -V

But got following error.

ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: mechanize requires mime-types (~> 2.0); mail requires mime-types (~> 1.16)

Please confirm.

Editing fluentd config file does not validate new config file

If I wrote invalid config file, fluentd-ui accepted the file and restarted fluentd. But it should validate the config file so that fluentd can always start.

Update sucker_punch gem

Latest sucker_punch replaces celluloid with concurrent-ruby.
It is good for reducing gem dependencies.

fluentd process management (eg. start, stop, etc)

Implement Editor feature for Edit Config File

Editor on Edit Config File doesn't have no text editor feature.
Feature to insert TAB and to select multiple lines, and to color for tags should be more better to editor config file.

Visualization error with \#

In the UI conf file editor, when you \# it is marked as a comment (gray colour). But when you run the agent it works correctly (not as a comment).

Preview format nginx|apache2|etc

Installation issue around sass

On Ubuntu 12.04, I got the following error message while running gem install -V fluentd-ui

ERROR:  Error installing fluentd-ui:
        invalid gem: package metadata is missing in /home/vagrant/.rbenv/versions/2.1.4/lib/ruby/gems/2.1.0/cache/sass-3.2.19.gem

I do have node installed

node --version

Change some parameters on fluent-plugin-td settings

Match

Setting default value, td.*.*, seems better.

Remove parameters

These parameters are for very rare case.

use_ssl
endpoint
xxx_timeout

APIKEY

Can you check API Key is valid or not in this configuration process?
If it could be implemented, users avoid the invalid API key trouble.
This is not critical but support is better.

in_tail multi line support

http://docs.fluentd.org/articles/in_tail

Add new UI parts for generate such config.

format multiline
format_firstline /^Started/
format1 /Started (?<method>[^ ]+) "(?<path>[^"]+)" for (?<host>[^ ]+) at (?<time>[^ ]+ [^ ]+ [^ ]+)\n/

Want `uname -a` result to detect OS / Kernel version in system information download

It is useful for debugging the problem.

Gather configuration, log file and system information.

Easy to investigate the problem.

Don't render un-related parameters in plugin configuration

For example, s3 plugin generator generates following configuration with json format:

<match s3.**>
  type s3
  aws_key_id XXXXXXXXXXXXXXXXXXXXXX
  aws_sec_key XXXXXXXXXXXXXXXXXXXXXXXX
  s3_bucket fluent-plugin-s3
  path test
  format json
  include_time_key false
  add_newline false
  output_tag false
  output_time false
  store_as gzip
  use_ssl true
  buffer_type memory
  flush_interval 5s
  num_threads 2
</match>

Fluentd dumps some unused warnings when received this configuration.
So we should change render parameters for each formats.

Don't install ri and rdoc

We don't use ri and rdoc with fluentd / td-agent.
So installing gem with ri and rdoc is extra cost.

List and search plugins

More human readable version of http://fluentd.org/plugin/
Separate tables into filter, database and other sections.

customizable header?

Just small request which would help me - can you implement "customizable header" in UI? Our "herd" of fluentd installations is growing so it would help me to see immediately with which fluentd-ui I am currently working.

User management

Use id:admin / password:changeme as default for now.

Create "Add Data Source" Button

Create "Add Data Source" button, to add data source to running Fluentd. The candidates for data sources are:

tail
syslog

(cc: please add possible data sources @repeatedly)

Broken updated plugins page

http://gyazo.com/f5907787907856cc58a465cef420c19b.png

Bottom span tag is not needed.

Need buffer_path parameter when select 'buffer_type file'

Similar to #157 .
buffer_type file without buffer_path causes validation error at configuration phase so
need buffer_path parameter when selects file buffer_type.

Configure plugins

Configure plugin and apply modified configuartions to fluentd configuration file.

After modifed, restarting Fluentd is needed: https://github.com/treasure-data/fluentd-ui/issues/3

Fix unstable Circle CI spec

Failures:

  1) Fluentd::Agent::LocalCommon #config_write keep files num up to max
  Failure/Error: expect(backup_files.size).to eq ::Settings.max_backup_files_count

    expected: 100
         got: 101

    (compared using ==)
  # ./spec/models/fluentd/agent/local_common_spec.rb:71:in `block (3 levels) in <top (required)>'

Sometimes our spec is failed on Circle CI as above. got: 101 is dancing about 100-110 range.
