Brian Brazil ca050b599d Merge pull request #204 from pborzenkov/centos6-meminfo-numa-fix 
meminfo_numa: fix crash on CentOS 6 kernel
 2016-02-06 13:17:34 +00:00
Pavel Borzenkov 5a085dcaf5 meminfo_numa: fix crash on CentOS 6 kernel 
It turns out, on some kernels (notably - CentOS6) there is an empty line
inserted at the beginning of /sys/devices/system/node/node*/meminfo
files.  The leads to node_exporter crash on such kernels.

Fix this by checking for empty string first.

Tobias Schmidt 3a96e6881b Remove unused flag -debug.memprofile-file 
The option to write out a memory profile to file was removed in a730cff.
Declaring flags as local variable does not only result in cleaner, more
testable code, but also ensures that the program won't compile anymore
when unused flags are left in place.

Tobias Schmidt 33f99c4fc1 Vendor all dependencies 
Uses godep to vendor dependencies. Godeps is not necessary during build,
golang's new vendor support is used instead.

Pavel Borzenkov 0e78ed63a6 Add new collector exposing 'ksmd' stats 
Add new collector which exposes the content of /sys/kernel/mm/ksm
directory. This directory contains control and statistics files for
Kernel Samepage Merging daemon.

The collector is not enabled by default.

Pavel Borzenkov 21d473ffd4 Fix compilation without conntrack collector 
Entry collector uses readUintFromFile() function which is defined by
conntrack collector. Thus, it is impossible to build node_exporter w/o
conntrack collector. Fix this by factoring out the function into
helper.go file.

Pavel Borzenkov c12d8ea927 Add new per NUMA node memory statistics collector 
It is sometimes useful to understand the distribution of free/occupied
memory between NUMA nodes to deal with performance problems. To do so,
add new meminfo_numa collector that enables exporting of per node
statistics along with unit and end-to-end tests for it.

Logical sector size appears to be fixed at 512B for the foreseeable
