We can most likely meet our metrics endpoints discovery need using conventions and kubernetes_sd_config.

While we're at it we should revisit long term storage and querying.

We must do service discovery using conventions + labels. Make sure that ystack uses port names along with modern community standards for prometheus discovery, then update SD config so that it has no specific targets. I'm fine with more than one SD config as long as it's clear how a pod in any namespace can match it. Also ServiceMonitor sometimes is a use case so we need an example of that in ystack.

Replace prometheus-operator with vanilla Prometheus v3.10.0
32847d1
Remove all monitoring.coreos.com CRDs (Prometheus, Alertmanager,
ServiceMonitor, PodMonitor, PrometheusRule) and replace with plain
Kubernetes Deployments, ConfigMaps, and scrape config.
Prometheus now uses kubernetes_sd_configs for target discovery
instead of operator-managed ServiceMonitor/PodMonitor CRDs.
Recording rules moved from PrometheusRule CRD to a ConfigMap-mounted
rules file. A configmap-reload sidecar triggers /-/reload on changes.
Consolidates k3s/30-monitoring-operator + k3s/31-monitoring into
a single k3s/30-monitoring base. Updates converge and validate
scripts accordingly.

Add Thanos Receive + GreptimeDB with dual remote_write
5e9c90d
Deploy Thanos Receive (StatefulSet) + Query (Deployment) and
GreptimeDB standalone as competing remote_write backends for the
metrics-v2 experiment. Prometheus sends scraped metrics to both
via remote_write for side-by-side comparison.

Add metrics-v2 experiment results report
1663f28
Thanos wins 8.35 vs 8.00 over GreptimeDB on weighted criteria:
query correctness, operational complexity, resource usage, maturity,
and storage cost projection. All PromQL queries returned consistent
results across all three backends. Documents deviations from the
original experiment plan.

Update experiment report with S3 storage cost comparison
7e3d067
Both backends now write to versitygw. GreptimeDB's columnar format
produces 5.6x less data (252 KB vs 1.4 MB) for the same metrics
workload. This flips the storage cost score and brings the weighted
totals to a near-tie (Thanos 8.05 vs GreptimeDB 8.30).

We must do service discovery using conventions + labels. Make sure that ystack uses port names along with modern community standards for prometheus discovery, then update SD config so that it has no specific targets. I'm fine with more than one SD config as long as it's clear how a pod in any namespace can match it. Also ServiceMonitor sometimes is a use case so we need an example of that in ystack.

Replace prometheus-operator with vanilla Prometheus v3.10.0
32847d1
Remove all monitoring.coreos.com CRDs (Prometheus, Alertmanager,
ServiceMonitor, PodMonitor, PrometheusRule) and replace with plain
Kubernetes Deployments, ConfigMaps, and scrape config.
Prometheus now uses kubernetes_sd_configs for target discovery
instead of operator-managed ServiceMonitor/PodMonitor CRDs.
Recording rules moved from PrometheusRule CRD to a ConfigMap-mounted
rules file. A configmap-reload sidecar triggers /-/reload on changes.
Consolidates k3s/30-monitoring-operator + k3s/31-monitoring into
a single k3s/30-monitoring base. Updates converge and validate
scripts accordingly.

Add Thanos Receive + GreptimeDB with dual remote_write

Deploy Thanos Receive (StatefulSet) + Query (Deployment) and
GreptimeDB standalone as competing remote_write backends for the

Thanos wins 8.35 vs 8.00 over GreptimeDB on weighted criteria:
query correctness, operational complexity, resource usage, maturity,
and storage cost projection. All PromQL queries returned consistent
results across all three backends. Documents deviations from the
original experiment plan.

Update experiment report with S3 storage cost comparison
7e3d067
Both backends now write to versitygw. GreptimeDB's columnar format
produces 5.6x less data (252 KB vs 1.4 MB) for the same metrics
workload. This flips the storage cost score and brings the weighted
totals to a near-tie (Thanos 8.05 vs GreptimeDB 8.30).

Update experiment report with S3 storage cost comparison
7e3d067
Both backends now write to versitygw. GreptimeDB's columnar format
produces 5.6x less data (252 KB vs 1.4 MB) for the same metrics
workload. This flips the storage cost score and brings the weighted
totals to a near-tie (Thanos 8.05 vs GreptimeDB 8.30).

y-cluster-provision-k3d: skip sudo when /etc/hosts is already up to date
77af594
for provisioners that use a fixed IP.
Use y-k8s-ingress-hosts -check before attempting -write, so provision
can complete without a TTY or sudo when entries already exist.

We can most likely meet our metrics endpoints discovery need using conventions and kubernetes_sd_config.
While we're at it we should revisit long term storage and querying.

Requesting changes (I created the PR so I can't reject it formally).
Only core changes reviewed. I will look at the benchmark setup for long term storage later.

Do we need all of these? I'd prefer we avoid legacy versions.

We must do service discovery using conventions + labels. Make sure that ystack uses port names along with modern community standards for prometheus discovery, then update SD config so that it has no specific targets. I'm fine with more than one SD config as long as it's clear how a pod in any namespace can match it. Also ServiceMonitor sometimes is a use case so we need an example of that in ystack.

Replace prometheus-operator with vanilla Prometheus v3.10.0
32847d1
Remove all monitoring.coreos.com CRDs (Prometheus, Alertmanager,
ServiceMonitor, PodMonitor, PrometheusRule) and replace with plain
Kubernetes Deployments, ConfigMaps, and scrape config.
Prometheus now uses kubernetes_sd_configs for target discovery
instead of operator-managed ServiceMonitor/PodMonitor CRDs.
Recording rules moved from PrometheusRule CRD to a ConfigMap-mounted
rules file. A configmap-reload sidecar triggers /-/reload on changes.
Consolidates k3s/30-monitoring-operator + k3s/31-monitoring into
a single k3s/30-monitoring base. Updates converge and validate
scripts accordingly.

Downgrade alertmanager to v0.28.1 for experiment compatibility

v0.31.0 was not available in the container registry at experiment
time. Revert this commit to restore v0.31.0 once it is published.

Add Thanos Receive + GreptimeDB with dual remote_write
5e9c90d
Deploy Thanos Receive (StatefulSet) + Query (Deployment) and
GreptimeDB standalone as competing remote_write backends for the
metrics-v2 experiment. Prometheus sends scraped metrics to both
via remote_write for side-by-side comparison.

Add metrics-v2 experiment results report
1663f28
Thanos wins 8.35 vs 8.00 over GreptimeDB on weighted criteria:
query correctness, operational complexity, resource usage, maturity,
and storage cost projection. All PromQL queries returned consistent
results across all three backends. Documents deviations from the
original experiment plan.

Configure Thanos Receive and GreptimeDB to use versitygw S3 storage

Both backends now write to versitygw object storage for storage cost
comparison. Adds bucket-create jobs and S3 configuration for each.

Add 5m block duration override for experiment verification
b1e137d
WARNING comment included: these overrides should not be used in
production. Forces frequent block cuts so S3 uploads are visible
quickly during the metrics-v2 experiment.
