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. Signed-off-by: Pavel Borzenkov <pavel.borzenkov@gmail.com>	9 years ago
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.
