For system monitoring

Run once

docker run -v=/proc:/prochost:ro chrishiestand/linux-stats /prochost

Run in Loop, 60 seconds between runs

docker run -v=/proc:/prochost:ro chrishiestand/linux-stats /prochost 60

Data collection mode

docker run -d --restart=always -v=/proc:/prochost:ro chrishiestand/linux-stats /prochost 60

It's up to you to set the output to e.g. stdout or syslog and collect the metrics as you wish. In the future I may open source what I've done to solve that part of the problem.

Release Notes

v1.1

now required linux kernel 3.14 or greater because it uses MemAvail from /proc/meminfo and memory units are now KiB

v1.0

requires linux kernel version 2.16 <= x <= 3.13

Output

__BASH_METRIC_x where x is the version of the output format.

Columns are: measurement name_unit, measure value, timestamp in ms
