pm2 list

user is shown as undefined. This is not application dependent, can also affect other apps that are shown correctly in the screen shot.

Can't reproduce this issue.
We need more details to reproduce.

KaiSchwarz-cnic · 2018-03-23T16:15:10Z

We have a webhook app which restarts the apps via child_process.exec.
A more detailed description can be found here: #3276

If you need further informations, please feel free to ask.

wallet77 · 2018-03-23T17:03:09Z

I think this is the problem.
We find user in pm2.env variable. But if you restart app with a hook we can't catch the user.

KaiSchwarz-cnic · 2018-03-26T07:24:30Z

Doesn't make sense imo as this worked fine in the past.
We also provide the user in our pm2 configuration which we use to reload our apps.
So for sure pm2 should have access on this in the environment.

kepi · 2018-04-23T09:42:30Z

We have same problem when starting PM2 from systemd unit. Correct user is set in systemd unit, application but in pm2 list it shows undefined.

using standard systemd script generated from pm

KoteKotlyarov · 2018-04-25T15:00:17Z

Long story short:

Run pm2 l to see everything is ok
Run npm install pm2@latest -g && pm2 update
Saw in logs messages about updating from 2.8.0 to 2.10.2 version
Saw in logs message about "All apps restored" and response of pm2 status with all apps in "stopping" status with "undefined" users
Run pm2 l again and saw no apps at all (Why ? It said all aps were restored)
Run pm2 resurrect and saw all apps are running with "undefined" users

All these actions are on screenshot.

Then I did:

Made a copy of /.pm2/dump.pm2 file
Deleted one application from pm2 monitor and redeployed it
Run pm2 l to validate that user is "centos"
Run pm2 save and compare 2 dumps
Found "username" property in last dump for redeployed app
Add "username": "centos", manually in all apps in current dump file
Run pm2 stop all && pm2 delete all
Run pm2 resurect and see all apps have "centos" user

Is it OK to do it ?

Env is Centos 7

KaiSchwarz-cnic · 2018-05-02T15:26:28Z

@wallet77 any update? the current flag could be changed at least, thanks

wallet77 · 2018-05-02T15:48:28Z

Didn't have time to investigate.
I still need more information to find a way to reproduce, otherwise I can't really fix it.

KaiSchwarz-cnic · 2018-05-02T15:52:01Z

@wallet77 KoteKotlyarov provided a step by step guide, isn't that enough?

wallet77 · 2018-05-02T16:04:03Z

@Papakai Unfortunately no, on my computer I can't reproduce this issue.
Even if I type : npm install pm2@latest -g && pm2 update and if I follow all steps, my user is displayed as expected. I need to test on another environment I think.

kepi · 2018-05-03T10:20:31Z

In our cases problem was fixed by upgrading PM2 and multiple restart/resurrects. Now everything is ok, unfortunately cannot pinpoint exact command which fixed it.

KoteKotlyarov · 2018-05-03T10:47:45Z

@wallet77 I have mentioned analized dump files before and after doing those commands. The main different was in username property in app dump data.

In brief, to fix my issue was enough to add in old dump file username: centos for each app in dump file.
Looks like old version created dump without username property and new version tries to read that undefined username property. Its my opinion, didn't look into code.

It can be proofed by checking logic of creating and restoring dump file in 2 versions, for my case they were 2.8.0 and 2.10.2

wallet77 · 2018-05-14T15:27:35Z

@KoteKotlyarov indeed we change the dump file creating/restoring logic but it's not release. It's still on development branch.
Maybe another commit has an impact on this feature.

ghost · 2018-06-01T04:06:03Z

i have the same issue. My .pm2/dump file has no "username" field. I just did an upgrade to the latest version (first did pm2 save), then pm2 update and this happened.

Unitech · 2018-06-03T18:53:50Z

fixed, will be landed on next release

wallet77 · 2018-07-04T12:28:08Z

PM2 3.0.0 has been released:

$ npm install pm2@latest -g
$ pm2 update

Be aware of breaking changes, especially drop support for node 0.12.
