Active streams plugin or alternatively open files plugin

im sorry im not sure i understand what you mean

I'm not sure I understand what you don't understand, but on the Apps tab there are Plugins you can install to look at Active Streams and to look at Open Files.

ok i did that, with no dockers/vms running i am averaging 300 reads per second and the active streams are showing 0

 

The drive is also healthy

And what about Open Files?

 

You don't have your server exposed to the internet do you?

The File Activity Plugin is also a good one as it shows historical activity as well.  This helped me track down where Radarr was spinning up my drives

It is not exposed, its definately a docker. i have moved all configs to my cache drive, still reading one single drive like crazy, but i cant tell which app is killing that single drive because its not showing being "read" in open files

When i run this, and set the settings all to "yes" all i see is a blank screen. 

 

This is very wierd behavior, ive tried reinstalling the dockers and erasing app data but no luck. i moved the app data to cache too....i believe i did it all properly

Just an update....so ive turned dockers to "Off" and VMs to "off"

and im averaging 300 reads/per second.

Ive noticed this in open files still even after both Docker/Vms are off  Any suggestion as to what/why that is doing that?

 

find 9744 Kill 2 1

/mnt/disk6/Cache Backup/appdata/plex/Library/Application Support/Plex Media Serv ...
/mnt/disk6/Cache Backup/appdata/plex/Library/Application Support/Plex Media Serv ...

you have to increase Max Watches 'fs.inotify.max_user_watches' in the Tips & Tweaks plugin.  I've set mine to 720000

gets the file activity plugin working

 

 

  • Author

DZMM, that did not let file activity work, still blank.

 

Docker/VM off, server essentially idle, and the "find" process is scanning just that one drive constantly. new folders every time, new process ID.

 

any suggestions as to how i can find the "parent" process that is starting find?

Its Dynamix Cache Dirs

 

Exclude the Cache Backup share from the settings.  (And ideally your appdata share also, since its going to have tons and tons of files that trying to keep track of them all may result in other cached inodes getting dropped.

bump.....it went up to 117 million reads...help whats inotify wait please

inotifywait is a program that monitors files / folders for access to them, and then signals another program that something has happened.

 

I doubt that inotifywait itself is causing the reads.

 

Where its used off the top of my head:  OpenFiles, Dynamix File Integrity, Ransomware Protection and more, docker apps like Plex, Emby, Crashplan, and many more.

Restart in safe mode.  (Or keep docker disabled and start uninstalling plugins one at a time), but diagnostics never hurt.

ok so after restart in safemode what needs to be done? will dockers/VMs run?

Honestly I can't remember.  It used to be just plugins wouldn't get installed, but that changed.  You'll know by if there's a docker tab or vm tab.  Just disable whats actually not needed
