Matthias Loibl 77e76485c0
Use absolute jsonnet import paths 
This should be the way forward when importing libraries in jsonnet. It's
closer to how Go imports look and makes it more obvious where packages
live.

This is not breaking anything, as the old imports were already symlinks
to the now directly used directories.

Make FS space alerts thresholds configurable (#1624) 
* Make FS space alerts thresholds configurable (#1)

This makes it possible to tweak the thresholds for
the NodeFilesystemSpaceFillingUp alerts. Which
might be necessary in systems like Kubernetes,
where the image garbage collector runs at 85%,
so it's not a problem that the disk reaches that usage %.

beorn7 c6914477f5 Fix the normalization for the cluster-wide dashboards 
We actually have to count or sum, respectively, _all_ the selected
metrics for the cluster-wide view. Which means it's easiest to use the
`scalar` approach after all (but only in the cluster dashboard). This
still propagates all the labels.

I have extended the comment for the `nodeExporterSelector` to note
that the cluster dashboard only makes sense if all the selected node
exporter actually belong to the same cluster.

Since this is jsonnet, users can easily disable the cluster
dashboard. Or even create multiple instances of the dashboards with
different `nodeExporterSelector`s for different clusters.

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.

Sergiusz Urbaniak f4417b209a node-mixin: fix configuration for unset fsSelector/diskDeviceSelector 
As per https://github.com/prometheus/node_exporter/pull/1429#discussion_r304210103
we want to fetch all devices and all fs types.

Currently, this is done by setting empty string which breaks most queries which rely on it.

This fixes it by setting the appropriate selector instead of empty string.
