Fail: could not retrieve user/lsof metrics

I have pm2 and pm2-server-monit running on a Windows Server 2012 R2 machine.

I am seeing these issues/errors:

Fail: could not retrieve lsof metrics
Fail: could not retrieve user metrics

The number just keeps going up and I can't find any information on them.

It also says:

Infected deployments: Server infected

What does this mean and how do I fix it..?

no free/used disk space

Hi,
I'm unable to get the free/used disk space stats.
Drive param is / (I tried /opt too as this is the disk I'd like to monitor)
the disk usage command from the dashboard outputs
[+] Response has been successfully received:

in the logs I see lots of

thanks

ifconfig not available as non-root user

I've setup pm2 to a non-root user for security reasons. The issue is that ifconfig is not available to this user because /sbin is not on his path and I would like to keep it that way.

Is there any solution to this problem, e.g.: passing PATH env to pm2 or adding a config to specify the path to ifconfig?

Thanks

pm2 processes ? (question mark) on left side, beside process name

I have installed pm2 and it all went on fine. But I see a few question (?) marks when I run pm2 monit which I don't really understand what it means. I have set up the monitoring server too, as specified in https://app.keymetrics.io console.

? PM2 monitoring (To go further check out https://app.keymetrics.io)

The question marks that I am referring to are the ones in front of "index" e.g "? index"
I can see from some of the other screenshots on the web that it is supposed to be either a green or red circle. I have no idea as to what those circles are. Anyone can help me understand?

Add ability to specify different network device

My VPS uses not "eth0" as its network interface name but "venet0". Could you add an option in the future to be able to specify the network interface name please?

Wrong disk usage

I have some VPS on scaleway and pm2-server-monit reports 100% available disk at all times.

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
none            3.9G     0  3.9G   0% /dev
tmpfs           795M   22M  773M   3% /run
/dev/nbd0        46G   12G   32G  27% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup

As you see, the primary disk is mounted in /dev/nbd0 which is 27% used.

To much processes spawned

Yesterday we had problem on production servers with pm2-server-monit.
This module spawned over 600+ df -k processes and not killed them.
We had to remove module and kill processes manualy.

On my Keymetrics console, I'm not getting any data for Net in or out. Is there a config change that I'm missing? Client is CentOS 7.2.

Fail on Centos

Low memory warning does not accurately reflect the threshold which has been set

When the low memory threshold is adjusted from the 10% default to a custom value of 30% the error message generated by the system reads:

"Less than 10% memory available 30"

Ideally this message would more clearly state the event which occurred. "Less than 30% memory available".

CentOS 6.9 gets reported as Ubuntu 14.04

Add commands to retrieve output of commands:

list number of open files: lsof -i -n -P | wc -l
list top processes using memory: ps -eo pmem,pid,cmd | sort -k 1 -nr | head -10 | cut -c 1-60

Cannot change DRIVE. Always monitors first drive

The drive I want to monitor appears second.
Looking thought the code, the drive been monitored is hard coded to [1]
So the monitor was looking a udev instead of /dev/xvda1

> df -h
Filesystem      Size  Used Avail Use% Mounted on 
udev            2.0G   12K  2.0G   1% /dev   
/dev/xvda1      7.8G  6.0G  1.4G  82% /

Ideally we should be able to configure the monitor through the configuration file:
> pm2 set pm2-server-monit:drive /dev/xvda1

Having issue on windows

When I install it on windows using pm2 install pm2-server-monit its went crazy and keep opening new command windows and closing them. It acted like I have installed some virus. In a second it will open multiple command prompts and close them automatically and this goes on forever.

Can't start: Error: spawn ENOENT

Hi.
I have CentOS 7 on my VDS and I have been installed pm2 and pm2-server-monit. But I have this errors in my log:

Error: spawn ENOENT
    at errnoException (child_process.js:1011:11)
    at Process.ChildProcess._handle.onexit (child_process.js:802:34)

14 times with status errored in pm2 list and number 14 in restarts column.
What I need to do? I know that this tool is working on ubuntu 14.04 on this VDS. May be I have some unresolved dependencies?
Thank you for your attention

My pm2-server-monit-error-10.log log file is littered with the message above. No other useful output beside it.

Retrieve every possible temperature sensor

This feature will help to detect the temperature of server components (CPU, GPU, inner box...) and detect component overheat.

Linked to disk drive health check this would potentially allow to determine an index of server health.

CPU spikes to 100% with installation of pm2-server-monit

Hi guys,

Thanks for your wonderful work on this project.

A few days ago we had an outage that was a result of servers spiking to 100% CPU usage and becoming inoperable.

Start two processes, a web process and a application process with pm2
Add pm2-server-monit alongside a Keymetrics key. pm2 install pm2-server-monit && pm2 link XXX YYY $HOSTNAME
CPU spikes to 100%.
Remove pm2-server-monit - pm2 uninstall pm2-server-monit.
CPU returns to usual.

The application does not spike CPU when running with pm2-server-monit, indeed, it barely troubles > 10% CPU usage even for intensive operations. These are AWS m4.large instances.

I am wondering if we can walk through this problem together. The monitoring Keymetrics gives me at the moment (we are a paying customer) is useful and my own mitigation for now has been to remove the installation of pm2-server-monit from our deploy process.

TypeError: Cannot read property 'replace' of undefined

I had this error, when my server was overload (in 30 minutes I had 60 load).

Build Keymetrics interface for module

Like pm2-redis

TypeError: Incorrect value of args option

just installed and i am getting this exception on ubuntu 14.04.1 with node v0.10.31 and pm2 v0.14.3:

is there any necessary configuration or requirements i am missing?
