[mixin] Bloom dashboards are not using SSD job

[lindeskar]

Describe the bug

The rendered "Bloom Build" and "Bloom Gateway" dashboards in loki-mixin-compiled-ssd have job label values like:

• $namespace/bloom-planner
• $namespace/bloom-builder
• $namespace/bloom-gateway
• $namespace/index-gateway

When they should be something like these to support the SSD deployment mode:

• ($namespace)/(loki.*|enterprise-logs)-backend
• ($namespace)/(loki.*|enterprise-logs)-read

This leads to "No data" in the dashboards when following the standard of namespace/loki-component.

To Reproduce

Steps to reproduce the behavior:

1. Install Loki in SSD deployment mode
2. Install Grafana dashboards from loki-mixin-compiled-ssd or rendered with $._config.ssd.enabled
3. Scrape metrics from Loki components and set job to namespace/loki-component

Expected behavior

The dashboards show data.

Environment:

• Infrastructure: Kubernetes
• Deployment tool: Helm, mixin

Screenshots, Promtail config, or terminal output

Other dashboards seem to override the values with logic like:

loki/production/loki-mixin/dashboards/loki-reads.libsonnet

Lines 88 to 90 in 23b5fc2

	bloomGateway: if $._config.meta_monitoring.enabled
	then [utils.selector.re('job', '($namespace)/(bloom-gateway|%s-backend|loki-single-binary)' % $._config.ssd.pod_prefix_matcher)]
	else [utils.selector.re('job', '($namespace)/%s' % (if $._config.ssd.enabled then '%s-backend' % $._config.ssd.pod_prefix_matcher else 'bloom-gateway'))],

But this logic is missing in the mentioned dashboards:
