This commit changes the state package so that errors encountered while
expanding templates for custom labels and annotations are returned
from the function. This is not used at present, but will be used in the
future as we look at how to offer better feedback to users who don't
have access to logs, for example our customers who use Hosted Grafana.
This commit fixes a bug in the $values variable in notification
templates when using Classic Conditions. Since Classic Conditions
are not multi-dimensional, the values of each series that exceeded
the condition should be available as a RefID and offset. For example,
B0, B1, etc. However, this bug meant that instead just a single
condition would be printed as B, not B0.

* Record histogram of how long it takes to write history data
* Don't copy the registerer
* Adjust naming of write failures metric
* Introduce WritesTotal to complement WritesFailedTotal
* Measure TransitionsFailedTotal to complement TransitionsTotal
* Rename all to state_history
* Remove redundant Total suffix
* Increment totals all the time, not just on success
* Drop ActiveWriteGoroutines
* Drop PersistDuration in favor of WriteDuration
* Drop unused gauge
* Make writes and writesFailed per org

* Remove unnecessary whitespace
* Consistency improvements to help texts
* Update tests to match new descs
* Alerting: Add metrics for active receiver and integrations
Introduces metrics that allows us to track the number of configured receivers and integration in the Alertmanager for all orgs.
As a bonus, I realised that the alert reception metrics where not being exported nor collected. This does that too.
* revert to using folder store from the resolvers
* fixing tests after revert

* chore(services): replace dependencies on dashboard store with dashboard service
This continues the backend service/store split by replacing dashboard store dependencies with service dependencies. the folder service remains the single exception for now; otherwise we'd have a dependency cycle between the folder and dashboard services. I have some ideas for that, but I'll take care of all the easy parts first.
While doing this, I identified and removed a number of unused arguments from the following functions:
NewFolderNameScopeResolver
NewFolderIDScopeResolver
NewFolderUIDScopeResolver
NewDashboardIDScopeResolver
NewDashboardUIDScopeResolver
resolveDashboardScope
I have a small enterprise PR to support this commit.
* lingering fmt
* Loki backend and client depend on a requester
* Instrument all requests to loki using weaveworks TimedClient
* Construct collector in metrics package
This commit fixes an incorrect comment in the Result struct in eval.go
that I had written some time ago. The comment now documents the
actual behaviour and content of this field.
* Alerting: get alert rules on faults (#61248)
Two functions used to fetch alert rules from DB are updated:
- GetAlertRulesForScheduling
- ListAlertRules
Rows are scanned one by one so good ones are returned.
Common Error is logged with indication how many
rules failed on deserialization.
Resolved: #61248
* updates from review comments
This commit adds filterLabels, filterLabelsRe, removeLabels, and
removeLabelsRe functions to templates for custom labels and annotations.
It allows for use cases such as removing all private labels.
This commit changes the Data struct in template.go to use Labels
instead of map[string]string. It changes how labels are printed
when using {{ .Labels }} from map[foo:bar bar:baz] to
foo=bar, bar=baz.
This commit changes how labels are printed in templates for custom
annotations and labels from map[foo:bar bar:baz] to foo=bar, bar=baz.
Labels are comma separated, and sorted in increasing order.
This commit moves templating from the state package to a sub-package
called template. This sub-package will be the logical package for
future ease-of-use improvements to templating custom annotations
and labels.
* Use existing row struct instead of [2]string, add deserialization helper
* Replace Stream struct with stream struct which is exactly the same
* Drop unused status field
* Don't export queryRes and queryData
* Tests for custom marshalling
* Rename row fields to T and V for consistency with prometheus samples
* Rename row to sample
The `rule_groups_rules` metric is currently defined and computed by `State`.
It makes more sense for this metric to be computed off of the configured rule
set, not based on the rule evaluation state. There could be an edge condition
where a rule does not have a state yet, and so is uncounted.
Additionally, we would like this metric (and others), to have a `rule_group`
label, and this is much easier to achieve if the metric is produced from the
`Scheduler` package.
