The previous lookup filtered on aws_options->>'aws_access_key', which holds ciphertext, so static-key groups never matched. Groups with no access key skipped the filter entirely and matched every RDS exporter on the pmm-agent, letting one group's status overwrite unrelated exporters. Verified against a live PostgreSQL (testdb.Open) before this fix: the static-key lookup returned an empty agent list (encrypted column never equals the plaintext filter), and the ambient lookup returned both the ambient and the static-key agent's IDs (empty filter matched every RDS exporter on the pmm-agent). Both new subtests pass after this change. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>

Correct proto comments on aws_role_arn fields to name the actor that actually assumes the role: pmm-agent for AddRDSServiceParams, RDSExporter, AddRDSExporterParams, ChangeRDSExporterParams, and UniversalAgent. DiscoverRDSRequest correctly names PMM Server and is left unchanged. Includes regenerated .pb.go, swagger, and json client output from make prepare-pr. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>
Attribute discovery to PMM Server and adding/scraping to the pmm-agent host, consistent with the API comment fixes. Show the trust policy's Principal.AWS as an array so the cross-host case (trusting both identities) is directly copy-pasteable. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>
Per-region discovery errors are only logged, so a bad ARN or a missing sts:AssumeRole trust entry returned an empty list with HTTP 200. Assume the role once eagerly, inside the discovery timeout, and return FailedPrecondition when it fails. Derive the STS region from the partition that owns the ARN rather than from the union of configured partitions: STS is partition-scoped, so an aws-cn role must not have its AssumeRole sent to the aws partition, even when the ambient region says otherwise. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>
Pin the PGV pattern rejection to a 400 InvalidArgument with the field that failed, so the assertion cannot pass on a 500. Move AWSOptions.Validate next to the other AWSOptions methods in agent_model.go. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>
STS is partition-scoped, and the region to call it in is already known at the point of use: the region the fan-out is about to scan. Assume the role there rather than deriving a region from the ARN's partition, which made the STS region a second, independent notion of region alongside the one discovery already had. Record the assumption failure separately from the group error. Every region fails identically when a role cannot be assumed, errgroup keeps only whichever error arrived first -- in practice a context deadline, since 29 doomed STS attempts outlast the discovery budget -- and once the RDS call wraps the failure its outer error names RDS, not STS. Resolving the credentials in the goroutine and recording the first failure keeps the reported cause deterministic. Signed-off-by: Fergal Kearns <fergal.kearns@deliveroo.co.uk>

Clean up test-created PMM resources. These integration tests create persistent resources without registering t.Cleanup(), so a fatal assertion can leave state that contaminates later tests. Register cleanup immediately for every created exporter agent, PMM agent, RDS node, generic node, and service, including the rejected and malformed-ARN cases. The same requirement applies to the management RDS test.

Wrap the RDS exporter lookup error with operation context.
FindAgents can return a database or decryption error without identifying this fallback lookup or the PMM agent. Add the lookup operation and pmmAgentID before returning the error.
Proposed fix
if err != nil {
- return nil, err
+ return nil, fmt.Errorf("find RDS exporters for PMM agent %q: %w", pmmAgentID, err)
}Based on learnings, wrap lower-level errors that lack resource or operation context. As per coding guidelines, “Wrap errors with context: fmt.Errorf("descriptive context: %w", err).”

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Limit role assumption to the role ARN partition.
regions can include several AWS partitions. A role ARN belongs to one partition, but this loop attempts it in every configured partition.
A role can succeed in its own partition and fail in another partition. The first failure can then be reported as an assumption failure when no RDS instance is found. Filter the scan regions by the role ARN partition before creating STS providers.

Folks, the docs cannot be merged with this PR. We are merging PRs well before the release which is why we don't want them to show up before PMM is released.
May I ask you to extract them to a separate PR while restoring the .md files from main, please?
I know, it's inconvenient, but that's what it is :(

Build one assumed-role credentials provider before the region scan, using the default STS region for the role ARN's partition, instead of one provider per scanned region. Resolve it once up front, so a role that cannot be assumed is reported immediately without scanning any region. This also removes the false assumption failure a role could trigger when the configured partitions cover regions the role does not belong to: those regions now just fail their normal RDS call instead of a misreported role-assumption error.

Adopt the assumed-role implementation from #5804 (by Fergal Kearns) onto current main, squashed into one commit. PMM can assume an AWS IAM role using its own ambient credentials instead of long-lived access keys, for both RDS discovery (on PMM Server) and rds_exporter scraping (on the pmm-agent host). Adds aws_role_arn across the RDS API surface, mutually exclusive with the access/secret key; assumes the role once per partition during discovery; groups rds_exporter processes by credential identity; and exposes --aws-role-arn on the pmm-admin RDS commands. AWS SDK bumped to the versions already on main, with service/sts promoted to a direct dependency. Docs are intentionally excluded; they land via #5838. Known defects from the #5804 review are fixed in follow-up commits on this branch. Original PR: #5804 Signed-off-by: Ante Gulin <ante.gulin@percona.com>

Fixes two defects in the DiscoverRDS assume-role path found reviewing #5804. The STS AssumeRole call ran on the raw request context, before the awsDiscoverTimeout region-scan deadline was applied, and the HTTP client had no timeout of its own. A slow or unreachable STS endpoint could hang DiscoverRDS for minutes. The assume now runs under its own awsDiscoverTimeout deadline and the HTTP client carries a matching per-request ceiling. The role ARN's partition was never checked against settings.AWSPartitions. A role in a partition PMM is not configured to scan could assume successfully and then fail every scanned region, or return nothing with no error. The partition is now rejected up front with FailedPrecondition, before any network call. stsRegionForRoleARN returns the partition for this check. Signed-off-by: Ante Gulin <ante.gulin@percona.com>

* PMM-15389 Add instance_id to inventory RDS node API/CLI AddRemoteRDSNodeParams had no instance_id field and `pmm-admin inventory add node remote-rds` had no flag for it, so every remote-RDS node created through the inventory path stored an empty identifier. rds_exporter then received `instance: ""`, logged "No scraper for <region>/, skipping." and collected nothing while the agent reported AGENT_STATUS_RUNNING. PMM-13157 split address from instance_id but wired the new field through the management API only; the inventory API and CLI were never updated. This adds instance_id to AddRemoteRDSNodeParams and to the CLI, and refuses the broken state at source: an empty identifier is rejected at node creation (InvalidArgument), and attaching an rds_exporter to a remote_rds node that lacks one is rejected at agent creation (FailedPrecondition), which also covers rows created before this fix. The stale "DB instance identifier" comment on the address field is corrected in both RemoteRDSNode and AddRemoteRDSNodeParams. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Make --instance-id a required CLI flag The help text already said it was required, but Kong accepted an omitted value and sent an empty identifier the server then rejected.

Original PR: #5804 Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Bound and validate RDS role assumption in discovery Fixes two defects in the DiscoverRDS assume-role path found reviewing #5804. The STS AssumeRole call ran on the raw request context, before the awsDiscoverTimeout region-scan deadline was applied, and the HTTP client had no timeout of its own. A slow or unreachable STS endpoint could hang DiscoverRDS for minutes. The assume now runs under its own awsDiscoverTimeout deadline and the HTTP client carries a matching per-request ceiling. The role ARN's partition was never checked against settings.AWSPartitions. A role in a partition PMM is not configured to scan could assume successfully and then fail every scanned region, or return nothing with no error. The partition is now rejected up front with FailedPrecondition, before any network call. stsRegionForRoleARN returns the partition for this check. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Gate RDS role ARN on pmm-agent 3.4.0 A pmm-agent older than 3.4.0 bundles an rds_exporter that assumes an IAM role from empty static credentials rather than the ambient chain, so the sts:AssumeRole is never signed and the exporter dies with EmptyStaticCreds. Before this, a current server accepted --aws-role-arn for such an agent, returned success, and left the exporter failing with no server-side signal. CreateAgent and ChangeAgent now reject a role-based rds_exporter whose pmm-agent is below PMMAgentMinVersionForAWSRoleARN (3.4.0-0), with FailedPrecondition. Static-key exporters are unaffected. An agent with no reported version is treated as unsupported, which is the safe default. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Make clearing an RDS role ARN an explicit change Clearing the role ARN (--aws-role-arn="") without also supplying keys leaves the exporter with empty AWS options, so rds_exporter falls back to the pmm-agent host's ambient credentials - often a broader identity than the role the operator deliberately chose. This transition was silent: the CLI printed only "cleared AWS role ARN". Ambient credentials are a legitimate mode, so this is not rejected; instead it is made explicit. The pmm-admin change command now states that the exporter will use the host's ambient credentials when the ARN is cleared without keys, the flag help spells out the mutual-exclusion and clear semantics, and ChangeRDSExporter logs a Warn covering the API and UI callers that do not see the CLI message. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Version pmm-server in roster role-ARN test The 3.4.0 role-ARN gate rejects a role-based rds_exporter whose pmm-agent reports no version. TestRoster/GetFallbackHandlesRoleARN creates one on the built-in pmm-server agent, which the test fixtures seed without a version, so the gate refused it. Give that agent a supported version in the test, as any running 3.4.0+ server would report once the built-in agent connects. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Allow RDS role ARN when pmm-agent version is unknown The pmm-agent 3.4.0 gate rejected a role ARN whenever IsAgentSupported returned any error, which includes the 'no version info' case for a pmm-agent that has not connected yet. Reject only AgentNotSupportedError (a pmm-agent known to be too old); an unreported version no longer blocks storing the config and the gate re-checks once the agent connects. This is what the api-test TestRDSExporter/WithRoleARN and the feature's own intent expect. Signed-off-by: Ante Gulin <ante.gulin@percona.com> (cherry picked from commit 1ebc19b) * PMM-15389 Fix golangci-lint findings in RDS role ARN code Shorten the change-agent role-ARN help to satisfy lll, drop the named returns on stsRegionForRoleARN, and remove a redundant .Querier selector in the roster test (golangci-lint --fix). Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Tighten role-ARN version gate and STS timeout Address CodeRabbit review on #5944: - The role-ARN gate allowed on any non-AgentNotSupportedError, so a present-but-malformed pmm-agent version (and, on the change path, a PMM Agent lookup error) silently persisted an unverifiable role ARN. Add an ErrAgentVersionNotReported sentinel and allow only that case; reject the rest. - DiscoverRDS reported an STS timeout as FailedPrecondition; return DeadlineExceeded for context cancellation/deadline instead. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Backfill instance_id on remote RDS nodes Migration 110 filled instance_id only for the remote RDS nodes that existed at the time. AddRemoteRDSNode never passed InstanceID on, so every node created through the inventory API or `pmm-admin inventory add node remote-rds` since then has an empty instance_id. Its rds_exporter queries CloudWatch with an empty DBInstanceIdentifier, and the new guard now refuses to attach an exporter to it at all, with no API to update the node. Fill it in from the first label of the address. That is the DB instance identifier whether the address holds the bare identifier, as the inventory API documents, or the RDS endpoint. Nodes that already have an instance_id are left alone. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Refuse role ARN on unversioned pmm-agent The role ARN check let through a pmm-agent that had not reported a version yet. Such an agent can be older than 3.4.0: it would accept the config, report RUNNING and scrape nothing. Nothing checks the version again once the agent connects, despite what the comment said. Treat an unreported version like any other failed version check, as IsAgentSupported does everywhere else, and drop the ErrAgentVersionNotReported sentinel that only served this exception. The api-test that stored a role ARN on a never-connected pmm-agent now uses the pmm-server agent, and a new subtest checks that the never-connected case is refused. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Refuse duplicate RDS instance IDs UNIQUE (address, region) used to cover the DB instance identifier because the address was the identifier. Since the address became the endpoint, two remote RDS nodes in one region can carry the same instance_id, and rds_exporter then queries CloudWatch for that instance twice. Check instance_id and region when creating a remote RDS node, next to the address check. The check is in the application only, since existing data may already hold duplicates or empty values. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Withhold role-based RDS exporters from old agents The pmm-agent version was only checked when an rds_exporter with a role ARN was created or changed. A pmm-agent downgraded below 3.4.0 afterwards still received the role in its state, ran an rds_exporter that ignores it, reported RUNNING and scraped nothing. The state updater now re-checks the version every time it sends the state and leaves such an exporter out with a warning. The change-time gate runs only when the request sets a role ARN, so an exporter stuck on a downgraded agent can still be disabled, relabelled or moved to ambient credentials. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Avoid %q in RDS role error messages Partitions and role ARNs contain no spaces, so %s reads better and follows the error message convention. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Scan only the role's partition in RDS discovery Credentials assumed for a role are valid only in the role's own partition, yet discovery scanned every region of every enabled partition. The extra calls could only fail, and when the role's partition had no instances the first such failure was returned instead of an empty list. The discovery tests now run the role path against a fake STS and RDS endpoint and check, from the SigV4 credential scope, which regions were signed. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Derive instance_id from bare RDS address Before 3.4.0 the inventory API took the DB instance identifier as the address, and rds_exporter used the address as its instance. Clients from that time, including older pmm-admin builds, still send it that way and omit instance_id. PMM-13157 moved the exporter to instance_id without wiring the inventory path, so those clients have scraped nothing since, and the new empty-identifier check would have rejected them outright. When instance_id is empty and the address has no dots, use the address as the identifier, which restores the pre-3.4.0 contract. An endpoint address without an identifier is still refused: its first label is only right for a standard instance endpoint, not for a cluster endpoint, a CNAME or an IP. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Backfill instance_id from bare addresses Splitting the first label off an endpoint stores a wrong identifier for an Aurora cluster endpoint, a CNAME or an IP. rds_exporter drops such an instance with "can't determine resourceID" just as it does an empty one, but the wrong value passes the new CreateAgent guard, looks plausible in the inventory, and cannot be corrected through the API. Backfill only rows whose address has no dots, the same rule the creation fallback uses. Endpoint addresses stay empty so that attaching an rds_exporter is refused and the node is re-added with --instance-id. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Limit rds_exporter to remote RDS nodes Generic and container nodes allow every agent type, so an rds_exporter could be attached to one and skip the instance_id guard. The guard would not help there anyway: migration 110 copied the address into instance_id for every node type. rds_exporter scrapes CloudWatch for the node's region and DB instance identifier, so it only makes sense on a remote RDS node. Refuse the combination in compatibleNodeAndAgent and drop the node-type condition from the guard, which is now redundant. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Lowercase RDS instance identifiers AWS stores DB instance identifiers in lowercase, and rds_exporter compares the configured value against DescribeDBInstances with plain string equality before using it as the CloudWatch dimension. A mixed-case identifier never matches, and the uniqueness check does not see it as a duplicate of the lowercase one. Lowercase the identifier in createNodeWithID before validation, storage and the uniqueness check, which covers the inventory and the management path. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Test --instance-id parsing Cover the required flag and the request body: parsing fails without --instance-id, and the value reaches remote_rds.instance_id. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Clarify RDS node address comments Nodes created before 3.4.0 or through the inventory API hold the bare identifier in address, not the endpoint. Say so on both messages, describe the instance_id fallback and lowercasing, and call RemoteRDSNode.instance_id a DB instance identifier rather than an AWS instance ID, which reads like an EC2 ID. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Update API descriptors Add the instance_id field on AddRemoteRDSNodeParams to the buf breaking baseline. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Lowercase identifiers in migration 119 Migration 110 copied the address into instance_id as typed, and the management API stores the identifier it is given, so existing remote RDS nodes can carry a mixed-case identifier. AWS stores DB instance identifiers in lowercase and rds_exporter matches them exactly, so such a node passes the new guard and still scrapes nothing. Lowercase existing identifiers and the backfilled bare addresses, the same rule createNodeWithID now applies to new nodes. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Regenerate nodes.pb.go with make gen The file committed in bdbbe96 came from make -C api gen without the formatting pass that make gen runs last, so CI's format check restored the blank line gofumpt inserts before the depIdxs declaration. Regenerated with make gen and make format in the devcontainer; that blank line is the only change. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Honor AWS_REGION when assuming RDS role DiscoverRDS always assumed the IAM role against the partition's home region (us-east-1 for commercial AWS), even when PMM Server had a region configured. A server whose egress is limited to one region could never reach that STS endpoint and failed with "Timed out assuming role". Assume the role in the region the AWS SDK resolved from AWS_REGION, AWS_DEFAULT_REGION or the profile, and keep the partition default only as the fallback for a server with no region configured. A configured region outside the role's partition cannot issue its credentials, so reject it up front with a FailedPrecondition that names the variable, before any network call. Only the STS call moves. Region scanning, the partition allow-list in settings, and the discovery deadlines are unchanged. Signed-off-by: Ante Gulin <ante.gulin@percona.com> * PMM-15389 Allow AWS_REGION env vars in pmm-managed AWS_REGION and AWS_DEFAULT_REGION now steer which STS endpoint PMM Server uses to assume an RDS role, so they are documented input rather than unknown variables. Skip them in the environment parser alongside the existing AWS_ACCESS_KEY and AWS_SECRET_KEY case instead of logging "unknown environment variable" at startup.
