Adds a single GCP Monitoring dashboard that surfaces CPU and memory
across all Sigstore GKE workloads (grouped by namespace / container),
so oncall does not have to navigate multiple metric pages while
investigating resource issues.
The dashboard includes:
- CPU usage in cores (rate of core_usage_time)
- Memory used (non-evictable bytes)
- CPU/memory limit utilization (REDUCE_MAX so a hot replica is visible)
- CPU/memory request utilization (REDUCE_MAX)
- Container restart deltas
- Node CPU allocatable utilization

The xyChart threshold schema does not accept color/direction for these chart types; the dashboard create rejects them. Keep just the value. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Signed-off-by: Eugene Jahn <ejahn@sigstore.dev>
Heights of 16 in a 12-column mosaic produced very tall narrow tiles. Use h=4 (standard) for charts and keep h=4 for the overview banner. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Signed-off-by: Eugene Jahn <ejahn@sigstore.dev>
…iles to workloads dashboard Mirrors the standard GKE Workloads dashboard so oncall does not have to navigate to multiple pages to find resource usage charts: - Pod network received / sent (per namespace) - Ephemeral storage used (per container) - Node memory allocatable utilization (sibling of node CPU) - Running containers per namespace (uptime count) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Signed-off-by: Eugene Jahn <ejahn@sigstore.dev>
Previous tile used ALIGN_COUNT + REDUCE_SUM, which sums sample counts within the alignment window and is an approximation of container count. Switch to ALIGN_MEAN per series + REDUCE_COUNT across series so the y-axis is the exact number of running containers per namespace.

Summary
Adds a single GCP Monitoring dashboard
Workloads CPU & Memorythat consolidates CPU and memory across all Sigstore GKE workloads (grouped by namespace / container_name), so oncallers do not have to navigate multiple metric pages while investigating resource issues.It includes (per namespace / container):
Aggregations use
REDUCE_MAXon utilization charts so a single hot replica stays visible, andREDUCE_SUMon usage charts to show total per workload.Wired in via a new
google_monitoring_dashboard.workloadsresource ingcp/modules/monitoring/infra/dashboards.tf(same pattern as the existingclients,timestamp_authority, andrekor_v1dashboards).Testing
terraform fmt -recursivecleanWill roll out to staging first via the usual Sigstore CI flow once merged.
