vfs.dev.read/write.bps Support

[rrm74001]

Recently, I have been looking in to ways I can collect disk IO performance (specifically read/write throughput) data from my Linux machines using Zabbix. In looking at the items available:

https://www.zabbix.com/documentation/2.0/manual/appendix/items/supported_by_platform

I see options for vfs.dev.read/write.bps, but it indicates that it is not supported under Linux, only FreeBSD. Is collecting this information simply not feasible under Linux, or has it just not been implemented yet?

I found a workaround here, dated way back in 2007:

http://www.muck.net/19/getting-hard-disk-performance-stats-from-zabbix

and have been collecting data using this method for a few months, but I am unsure of how accurate it is. Is there a more official/less cumbersome method of achieving this?

just write the delta values from /proc/diskatates

nothing you can do wrong.
should be easy testing with writing, copyying files to verifiy the values on a non busy box.

This should be logged as a bug. ops works fine. No reason bps shouldnt be.

Yes, it is very good reason to ignore such report. Why? On all systems is not possible to do VFS read/write with single bits granularity.
To be honest only by this it is very good reason to log this metrics as bug .. and remove it.
