Add a new endpoint for "resource" metrics `/v2/metrics/resource`
This should return system metrics related to drives, network, CPU and
memory. Except for drives, other metrics should have corresponding "avg"
and "max" values also.
Reuse the real-time feature to capture the required data,
introducing CPU and memory metrics in it.
Collect the data every minute and keep updating the average and max values
accordingly, returning the latest values when the API is called.
without this the rename2() can rename the previous dataDir
causing issues for different versions of the object, only
latest version is preserved due to this bug.
Added healing code to ensure recovery of such content.
not checking w.Close() can prematurely make us
think that the w.Write() actually succeeded, apparently
Write() may or may not return an error but sometimes
only during a Close() call to the fd we may see the
error from Write() propagate.
Fdatasync(w) on the FD would return an error requiring
Close() error handling is less of a concern, however it may
happen such that fdatasync() did not return an error, where
as Close() would.
Currently, setting a new tiering target returns an error when a bucket
is versioned and the tiering credentials does not have authorization to
specify a version-id when reading or removing a specific version;
Since tiering does not require versioning anymore; avoid doing versioned
operations when performing checklist ops while adding a new tiering
configuration.
Do not error out when a provided marker is before or after the prefix, but instead just ignore it if before and return an empty list when after.
Fixes#18093
Include object and versions heal scan times when checking non-empty abandoned folders.
Furthermore don't add delay between healing versions, instead do one per object wait.
This PR changes the StatObject() to be must have for non-minio source
to being a conditional API call.
- Calls StatObject() when needed
- Calls GetObjectTagging() when needed
These calls if we do without these conditionals can cause a lot of
delays, so we avoid them if not needed in more common scenario.
all retries must not be counted as failed messages,
a failed message is a single counter not for all
retries, this PR fixes this.
Also we do not need to retry 10-times, instead we should
retry at max 3 times with some jitter to deliver the
messages.
If MinIO started with KMS enabled, MINIO_KMS_KES_KEY_NAME should
be set for server to start.

In a perf test, one node will run speed test with all nodes. If there is
an error with a peer node, the peer node name is not included in the
error hence confusing the user.
This commit will add the peer endpoint string to the netperf error.
To ensure that policy mappings are current for service accounts
belonging to (non-derived) STS accounts (like an LDAP user's service
account) we periodically reload such mappings.
This is primarily to handle a case where a policy mapping update
notification is missed by a minio node. Such a node would continue to
have the stale mapping in memory because STS creds/mappings were never
periodically scanned from storage.
- we already have MRF for most recent failures
- we trigger healing during HEAD/GET operation
These are enough, also change the default max wait
from 5sec to 1sec for default scanner speed.
AccountInfo is quite frequently called by the Console UI
login attempts, when many users are logging in it is important
that we provide them with better responsiveness.
- ListBuckets information is cached every second
- Bucket usage info is cached for up to 10 seconds
- Prefix usage (optional) info is cached for up to 10 secs
Failure to update after cache expiration, would still
allow login which would end up providing information
previously cached.
This allows for seamless responsiveness for the Console UI
logins, and overall responsiveness on a heavily loaded
system.
From the Go specification:
"3. If the map is nil, the number of iterations is 0." [1]
Therefore, an additional nil check for before the loop is unnecessary.
