Running on windows, p2-server-monit is calling linux commands #78

Open ebors opened 6 years ago

ebors commented 6 years ago

Running pm2 on windows causes many errors. The pm2 process want to call unix commands like top, who, grep etc. :

@carlosen14 I am facing the exact issue. any solution for it

carlosen14 commented 5 years ago

nope, just let it go... :(

jordy-leung commented 5 years ago

Hi, I'm having similar issue still...is it still outstanding issue and not fixed yet? Here is my log:

pm2-server-monit > Failed to retrieve TTY metrics { Error: Command failed: who | grep -v localhost | wc -l

Doc999tor commented 4 years ago

Any updates with it?

malkico commented 4 years ago

Similar issue on September 2020 !

Problem happens here, my problem was that my Docker container was using a Debian without the top process. I just installed the 'procps' package using apt and things are fine now.

MSIPhil commented 3 years ago

Any updates on this? It is quite annoying.

Konders commented 1 year ago

Issue exists 5 years and reproducible on your official docker image(18-alpine)

Issue still exists, I console log alot of stuff and this error is clogging up my logs which is real annoying. Might just uninstall server-monit since I can just RDP into my server in like 5 seconds and check task manager. Thanks PM2 for ignoring an issue since 2018!

WindsurfAR commented 1 month ago

So, in case someone wants to get rid of those errors: Go to C:\Users\YOURUSER\.pm2\modules\pm2-server-monit\node_modules\pm2-server-monit\src\metrics and check every file in there for fetch() functions (those do the unix commands through an exec). Then just delete their contents or comment them. For example in tty.js change:

fetch () {
    exec('who | grep -v localhost | wc -l', (err, stdout, stderr) => {
      if (err || stdout.length === 0) return console.error(`Failed to retrieve TTY metrics`, err)
      this.ttyCount.set(parseInt(stdout))
    })
  }

to:

fetch () {
}

Far from a clean solution, but the errors will be gone and I don't miss any feature.
