Benoît Knecht 5a7b85876d docs/node-mixin: Improve memory pressure rule The `instance:node_memory_swap_io_pages:rate1m` rule was intended to measure the amount of memory pressure a system is under, but its name is a bit misleading (it specifically refers to swap), and the rate of `node_vmstat_pgmajfault` is a better metric for memory pressure (see #1524). This commit renames `instance:node_memory_swap_io_pages:rate1m` to `instance:node_vmstat_pgmajfault:rate1m`, and defines it as `rate(node_vmstat_pgmajfault{%(nodeExporterSelector)s}[1m])`. The dashboards are updated accordingly. Signed-off-by: Benoît Knecht <benoit.knecht@fsfe.org>	6 years ago

Benoît Knecht 5a7b85876d docs/node-mixin: Improve memory pressure rule

The `instance:node_memory_swap_io_pages:rate1m` rule was intended to
measure the amount of memory pressure a system is under, but its name is
a bit misleading (it specifically refers to swap), and the rate of
`node_vmstat_pgmajfault` is a better metric for memory pressure
(see #1524).

This commit renames `instance:node_memory_swap_io_pages:rate1m` to
`instance:node_vmstat_pgmajfault:rate1m`, and defines it as
`rate(node_vmstat_pgmajfault{%(nodeExporterSelector)s}[1m])`. The
dashboards are updated accordingly.
