Include `job` filter for node resource checks about docker-flow-monitor

[vfarcic]

The reason I asked for the shortcut is because none expands to the expression you used. You're probably using the older Prometheus 1.x based DFM.

Anyways, most of the shortcuts had job baked in, except two. Now that's corrected and all are having job (or an equivalent). You can see the current list of shortcuts through https://github.com/vfarcic/docker-flow-monitor/blob/master/server/server.go#L261.

A new tag vfarcic/docker-flow-monitor:17.12.29-41 is building while I'm typing this. It'll be available in a few minutes.

@dave08 Can you please let me know the shortcut behind this expression? The closest I could find is @node_mem_limit. However, it is not the same. It expands to:

(sum by (instance) (node_memory_MemTotal) - sum by (instance) (node_memory_MemFree + node_memory_Buffers + node_memory_Cached)) / sum by (instance) (node_memory_MemTotal) > [SOME_VALUE]

Is that the one you're using?

Yes, I just gave an example of how I think it might look after the change, am I right? Also, this could apply to all yhe node related shortcuts like fs.. I just haven't (luckily) reached 80% disk usage yet...
