On windows, the user running the app needs to be able to run wmic. It is used to get the app's cpu usage.

This package should handle the error and show a warning that it is unable to get the app's cpu usage. Also, node 6 added process.cpuUsage which we could look into using instead when available.

@zodern So, what the solution ?? the package still prevent some code from running

Thank's

This is fixed in version 2.32.2. Instead of crashing the app, it will show a message in the logs, and the memory and cpu usage will show as 0 in the Monti APM UI.

The command that is failing is:

wmic PROCESS where ProcessId=<insert app PID> get CreationDate,KernelModeTime,ParentProcessId,ProcessId,UserModeTime,WorkingSetSize

You can try running it to see why it is failing. Remember to insert the PID of the app in the command.

Once soyuka/pidusage#63 is implemented it will be able to get the cpu and memory usage in Meteor 1.6 and newer without using wmic.
