Pushgateway, Pushes Persisted To Disk
Prometheus Pushgateway from the upstream release (sha256-verified) as a hardened system service on loopback with pushed metrics written to disk every five minutes, so a restart does not lose a batch job's last push. The live test pushes a metric, reads it back with its job label, deletes the job and reads it gone. Original role, live-tested on Rocky Linux 10.

Documentation
pushgateway
Prometheus Pushgateway from the upstream release tarball (sha256-verified), as a system service on loopback with pushed metrics persisted to disk. Original role for EL 10, live-tested with podman on Rocky Linux 10.
No package, so the checksum is the whole story. EL 10 carries no
pushgateway; Prometheus ships a release with a checksum file beside it. The
role downloads both and has Ansible's get_url refuse the asset unless its
SHA-256 is the one in the vendor's file, then installs the binaries as
root's in /usr/local/bin, pinned by pushgateway_version.
A service account, a hardened unit, a loopback listener. pushgateway
is a system user with no shell that owns the data directory and nothing
else; the unit runs with NoNewPrivileges, PrivateTmp, ProtectHome and
ProtectSystem=strict. The listener is 127.0.0.1:9091 by default,
for a proxy that authenticates or a client on the same host; the live test
reads the listening sockets and expects loopback only.
A push that survives a restart. The upstream default keeps pushed
metrics in memory only, so a restart drops the last push of a batch job
that will not run again until tomorrow; the role writes them to
/var/lib/pushgateway/metrics every five minutes. The live test pushes a
metric for a job, reads it back from /metrics with its job label,
deletes the job and reads it gone: push, serve and delete all ran. The
Pushgateway is for batch jobs; scraping a long-running service through it
is the mistake its own documentation warns about first.

Related modules
ansible-alertmanager
Prometheus Alertmanager from the upstream release (sha256-verified) as a hardened system service on loopback, its cluster gossip listener switched off and its configuration checked by amtool before it lands. The live test posts an alert through the API and reads it back active, held by the default receiver, and expects no 9094 listener at all. Original role, live-tested on Rocky Linux 10.
ansible-alloy
Grafana Alloy from the upstream release (sha256-verified) as a hardened system service on loopback with --disable-reporting, a self-scrape pipeline that proves the collector runs, and its configuration checked by alloy validate before it lands. The live test reads Alloy's own metrics and asks the component API for the scrape component's health. Original role, live-tested on Rocky Linux 10.
ansible-blackbox-exporter
Prometheus Blackbox exporter from the upstream release (sha256-verified) as a hardened system service on loopback with HTTP and TCP modules, checked by --config.check before the file lands. The live test has it probe itself over HTTP and TCP (probe_success 1) and a port with nothing behind it (probe_success 0): it measures, not only answers. Original role, live-tested on Rocky Linux 10.
ansible-grafana-server
Grafana on loopback with a secret key of yours: every install that never set one shares the package's, which encrypts the data-source credentials in its database. Secure cookies and HSTS for the TLS proxy in front; public snapshots, plugin update checks, feedback links and Gravatar switched off. Settings verified through the API, not the file. Original role, live-tested on Rocky Linux 10.
ansible-loki
Grafana Loki from the upstream release (sha256-verified) as a single-binary system service on loopback with filesystem storage, a TSDB index, retention the compactor enforces and usage reporting off, its configuration checked by loki -verify-config before it lands. The live test pushes one log line and queries it back. Original role, live-tested on Rocky Linux 10.
ansible-prometheus-server
Prometheus from the upstream release (EL 10 has no package), sha256-verified, on loopback: the binary listens everywhere and authenticates nobody. Retention time and size as explicit flags, lifecycle and admin endpoints off (the live test POSTs to both), prometheus.yml checked by the promtool it installs. Pairs with grafana-server and node-exporter. Original role, live-tested on Rocky Linux 10.
