The file:read_file(".../OTP_VERSION") call should be done in the background
This PR added a file:read_file/1 call needed for the Home page: #59
On my system, under specific circumstances, when I start observer_cli it takes 10+ seconds to show the Home page. The same problem happens when going to another page and coming back to the Home page. The Erlang node is doing a lot of file operations, and as a result the schedulers are not able to do this file:read_file/1 call in a timely manner. This is not good because this kind of scenario is precisely what I am trying to investigate.
The relevant code today is at https://github.com/zhongwencool/observer_cli/blob/master/src/observer_cli.erl#L781-L786 Removing these lines greatly improves the responsiveness of observer-cli in my case, with the downside being that the version now only shows "23".
I do not think removing the precise version is a good idea because the more accurate version is useful. However perhaps getting the more accurate version should be done in the background instead, and the value updated whenever the file:read_file/1 call has completed. Also I would suggest keeping this value cached to avoid reading the file every time the user goes back to the Home tab.
What do you think?

Observer_cli startup crash on OTP 23
This is happening with OTP 23.1.1

Lots of cores
I have a 64 vCPU machine with 128 schedulers set in vm.args (+S 128).
This is what my output looks like:
Keyboard does not work with Linux KDE 5
Hello
I'm trying to run observer_cli in KDE5 konsole.
Program starts normally, but it doesn't react at pressing any keys :(.
Why ?
Unable to connect remote ejabberd server
erl -sname `monitor@localhost`
observer_cli:start('ejabberd@nikhil5', 'actualcookiedata').
On the remote machine, the ejabberd server is running with node name ejabberd@nikhil5. On the same remote machine while running above command, the process monitor tool gives the following error-
badrpc,{'EXIT',{undef,[{observer_cli,start,[1500],[]},
{rpc,'-handle_call_call/6-fun-0-',5,
[{file,"rpc.erl"},{line,197}]}]}}}
Any suggestions/ideas why this is happening? Machine runs CentOS, and ejabberd-18.01, if that information is useful.
Support Nerves by no longer depending on hard-coded OTP_VERSION file location
I tried to add observer_cli to Nerves.
However, upon attempting to start it, it will crash with the following error:
00:01:22.567 [error] Process #PID<0.1234.0> on node :"[email protected]" raised an exception
** (MatchError) no match of right hand side value: {:error, :enoent}
(observer_cli) src/observer_cli.erl:607: :observer_cli.get_stable_system_info/0
(observer_cli) src/observer_cli.erl:123: :observer_cli.render_worker/3
Digging into the code, it seems that observer_cli is using a function called get_stable_system_info (which seems to only be used to display the full version (both major and minor) of OTP that under the covers attempts to read a file located at e.g. /srv/erlang/releases/22/OTP_VERSION
This location does not exist on Nerves (and actually the whole 22 folder) . The OTP_VERSION file can therefore not be read.
My suggestion would be to fallback to just set Version = erlang:system_info(otp_release) in case the file is not found, rather than crashing violently.
Rewrite process view to make it more clear and useful

Row numbers in plugins?
Is it possible to add row numbers in plugins, switching to a detail view when a row is selected?
Thank you!
output reports as serialized data
Observer CLI's reports use formatted ASCII and terminal control. Parsing this is certainly possible, but it would be far nicer (less hassle and possible error) if the reports could be made available in a serialized data format (e.g., Erlang Terms, GraphQL, JSON). Could this be added as an option?

OTP 21 compatability?

Clarify the how to use instructions
Can we clarify the instructions to get this working? I'm using an elixir project, I've added {:observer_cli, "~> 1.3"}, to my defp deps and omitted :observer_cli from def application do as per https://www.amberbit.com/blog/2017/9/22/elixir-applications-vs-extra_applications-guide/
Then I run the local shell with rebar3 shell followed by observer_cli:start()., but then I get:
** exception error: undefined function observer_cli:start/0Clearly I'm doing something wrong, but it's difficult to understand where this is the case. Can we add some more detail to the How To part of the readme to help people like me get started?
Observer_cli startup crash on OTP 22.2 on Solaris 11.3 (sparc)
Ets view incorrectly displays memory usage
Hi, thanks for the great tool!
We found an issue with Ets view (the one activated with E) incorrectly displaying memory size of the tables. It would seem that the value displayed corresponds to the value in {memory, X} tuple returned by ets:info/1. However, that value is in machine words, not in bytes. Home view (activated with H) displays the correct size.

Question around process list
Awesome work on this library! Very useful and well executed in my short time with it.
I may be missing something so wanted to ask. Is it possible to page/scroll through the process list to see additional processes, beyond what will fit in the buffer?
Cheers.
Manually adding dependency :recon necessary for mix
I had to add this to my Mixfile to make it work:
defp deps do
[
{:observer_cli, "~> 1.0.8"},
{:recon, "~> 2.3.2"}
]
end
It seems that the recon dependency is properly defined in observer_cli version 1.0.8 for mix.
Otherwise i get the following error when starting the application:
** (Mix) Could not start application recon: could not find application file: recon.app

io:format/2 calls stored in the release DEBUG log files
When connecting observer_cli escript to one of our VMs (Erlang 21.0), we noticed that all io:format/2 calls used by observer_cli where also send to our debug.log (we use the new Logger module) .
Then, the VM's CPU usage went super high.
Did anyone notice such a behavior?

This is running on AWS Fargate and it looks like the reason is that they have a non-standard ps command, it doesn't respond to --version or --help. This failure is handled on line 291 of observer_cli_system.erl but those "--" string values aren't subsequently supported.
catch io terminated exception ?
it might be related to otp 26, but can be caught at higher level, maybe.

How to get full names of processes within Home tab?
Hi, thank you for the library!
Is there way to fit Name or Initial Call column, so it shows full name of process?
Thanks!
Plugin per row shortcut
I would like to have my plugin be able to set a shortcut for each row in the sheet, similar to how we can choose processes in the Home view. In my case I could select a RabbitMQ queue I want to get more information about. It would be good if I could also link this detailed queue view to its detailed process view.
What do you think?

Plugin bytes conversion
Currently it seems I can only provide bytes as an integer. I am not sure how I should proceed to have the bytes formatted like the Home tab's Memory column for example 6.3586 MB. Is that something that is currently possible and if not, do you think it could be added?
Windows is broken
@zhongwencool - With SHA 7f80ae4 , running on Windows is broken as ps is not available. Suggest to check platform and run it conditionally.
在以mq排序来查看进程列表时发现存在一个进程有两条消息
环境
observer_cli version: 1.4.0

重现方式:
erl -pa $(rebar3 path)

猜测
怀疑是 observer_cli 开启的进程没有处理exit消息
Jump to process by pid
If I know the pid of a process, is there any way for me to jump directly to it? Without having to search through the list? I was thinking entering something like <#.#.#> and hitting enter?
(btw, we find this project super useful, thanks!)
