The semantics of honor_labels are that if a target exposes
and empty label it will override the target labels. This PR
fixes that by once again distinguishing between empty labels
and missing labels in this one use case.
Beyond that empty labels should be pruned and not added to storage,
which this also fixes.
Fixes#3841
There is currently no way to differentiate Windows instances from Linux
ones. This is needed when you have a mix of node_exporters /
wmi_exporters for OS-level metrics and you want to have them in separate
scrape jobs.
This change allows you to do just that. Example:
```
- job_name: 'node'
azure_sd_configs:
- <azure_sd_config>
relabel_configs:
- source_labels: [__meta_azure_machine_os_type]
regex: Linux
action: keep
```
The way the vendor'd AzureSDK provides to get the OsType is a bit
awkward - as far as I can tell, this information can only be gotten from
the startup disk. Newer versions of the SDK appear to improve this a
bit (by having OS information in the InstanceView), but the current way
still works.
The implementation of `sendAll` means that we observe latencies even for
notifications that would be considered dropped due to errors when
sending them.
Similarly, we count alerts as 'sent' even if an error occurred when
trying to send them (meaning they are potentially not sent at all).

If the GOBIN environment variable is set to a non-default location
relative to GOPATH, then promu will be built in this location and the
the build will fail because it tries to run $GOPATH/bin/promu.

* Fix JS error: cannot read source of undefined
When the page was refreshed with queries on the page,
the updateTypeaheadMetricsSet function was called before
the typeahead had been initialized.
* Fix: updates URL when query submits
When queries were submitted by pressing enter, the URL did not update
to reflect the change. Not sure why, but this was only the case when
the queries were non-simple, meaning when either labels werre specified
or other promql functions were used.
* Rebase master and make assets
This is a very minor UX change. The current "No Alert rules" present
table row has the `alert_header` class attached. This changes the cursor
and some other stuff and makes sense with the populated table but less
sense with the unpopulated table. So removing it the latter case.
This adds a parameter to the storage selection interface which allows
query engine(s) to pass information about the operations surrounding a
data selection.
This can for example be used by remote storage backends to infer the
correct downsampling aggregates that need to be provided.
When you have no alerting rules defined you get a screen sharing this
information in the WebUI. If no rules are defined then you instead see
an empty white screen. This adds a "No rules" defined `else` clause and
a `Rules` header to the page.
Currently the offsets are cast into uint32 even though the index can
grow larger than 4GiB.
