Make lock_manager.RenewInterval configurable in LiveLock (#7830)
* Make lock_manager.RenewInterval configurable in LiveLock - Add renewInterval field to LiveLock struct - Modify StartLongLivedLock to accept renewInterval parameter - Update all call sites to pass lock_manager.RenewInterval - Default to lock_manager.RenewInterval if zero is passed * S3 metrics: reduce collection interval to half of bucketSizeMetricsInterval Since S3 metrics collection is not critical, check more frequently but only collect when holding the distributed lock. This allows faster detection of any issues while avoiding overhead on non-leader instances. * Remove unused lock_manager import from bucket_size_metrics.go * Refactor: Make lockTTL the primary parameter, derive renewInterval from it Instead of configurable renew interval, lockTTL is now the input parameter. The renewal interval is automatically derived as lockTTL / 2, ensuring that locks are renewed well before expiration. Changes: - Replace renewInterval parameter with lockTTL - Rename LiveLock.renewInterval field to lockTTL - Calculate renewInterval as lockTTL / 2 inside the goroutine - Update all call sites to pass lockTTL values - Simplify sleep logic to use consistent renewInterval for both states This approach is more intuitive and guarantees safe renewal windows. * When locked, renew more aggressively to actively keep the lock When holding the lock, sleep for renewInterval/2 to renew more frequently. When seeking the lock, sleep for renewInterval to retry with normal frequency. This ensures we actively maintain lock ownership while being less aggressive when competing for the lock. * Simplify: use consistent renewInterval for all lock states Since renewInterval is already lockTTL / 2, there's no need to differentiate between locked and unlocked states. Both use the same interval for consistency. * Adjust sleep intervals for different lock states - Locked instances sleep for renewInterval (lockTTL/2) to renew the lock - Unlocked instances sleep for 5*renewInterval (2.5*lockTTL) to retry acquisition less frequently |

feat: add S3 bucket size and object count metrics (#7776)
* feat: add S3 bucket size and object count metrics Adds periodic collection of bucket size metrics: - SeaweedFS_s3_bucket_size_bytes: logical size (deduplicated across replicas) - SeaweedFS_s3_bucket_physical_size_bytes: physical size (including replicas) - SeaweedFS_s3_bucket_object_count: object count (deduplicated) Collection runs every 1 minute via background goroutine that queries filer Statistics RPC for each bucket's collection. Also adds Grafana dashboard panels for: - S3 Bucket Size (logical vs physical) - S3 Bucket Object Count * address PR comments: fix bucket size metrics collection 1. Fix collectCollectionInfoFromMaster to use master VolumeList API - Now properly queries master for topology info - Uses WithMasterClient to get volume list from master - Correctly calculates logical vs physical size based on replication 2. Return error when filerClient is nil to trigger fallback - Changed from 'return nil, nil' to 'return nil, error' - Ensures fallback to filer stats is properly triggered 3. Implement pagination in listBucketNames - Added listBucketPageSize constant (1000) - Uses StartFromFileName for pagination - Continues fetching until fewer entries than limit returned 4. Handle NewReplicaPlacementFromByte error and prevent division by zero - Check error return from NewReplicaPlacementFromByte - Default to 1 copy if error occurs - Add explicit check for copyCount == 0 * simplify bucket size metrics: remove filer fallback, align with quota enforcement - Remove fallback to filer Statistics RPC - Use only master topology for collection info (same as s3.bucket.quota.enforce) - Updated comments to clarify this runs the same collection logic as quota enforcement - Simplified code by removing collectBucketSizeFromFilerStats * use s3a.option.Masters directly instead of querying filer * address PR comments: fix dashboard overlaps and improve metrics collection Grafana dashboard fixes: - Fix overlapping panels 55 and 59 in grafana_seaweedfs.json (moved 59 to y=30) - Fix grid collision in k8s dashboard (moved panel 72 to y=48) - Aggregate bucket metrics with max() by (bucket) for multi-instance S3 gateways Go code improvements: - Add graceful shutdown support via context cancellation - Use ticker instead of time.Sleep for better shutdown responsiveness - Distinguish EOF from actual errors in stream handling * improve bucket size metrics: multi-master failover and proper error handling - Initial delay now respects context cancellation using select with time.After - Use WithOneOfGrpcMasterClients for multi-master failover instead of hardcoding Masters[0] - Properly propagate stream errors instead of just logging them (EOF vs real errors) * improve bucket size metrics: distributed lock and volume ID deduplication - Add distributed lock (LiveLock) so only one S3 instance collects metrics at a time - Add IsLocked() method to LiveLock for checking lock status - Fix deduplication: use volume ID tracking instead of dividing by copyCount - Previous approach gave wrong results if replicas were missing - Now tracks seen volume IDs and counts each volume only once - Physical size still includes all replicas for accurate disk usage reporting * rename lock to s3.leader * simplify: remove StartBucketSizeMetricsCollection wrapper function * fix data race: use atomic operations for LiveLock.isLocked field - Change isLocked from bool to int32 - Use atomic.LoadInt32/StoreInt32 for all reads/writes - Sync shared isLocked field in StartLongLivedLock goroutine * add nil check for topology info to prevent panic * fix bucket metrics: use Ticker for consistent intervals, fix pagination logic - Use time.Ticker instead of time.After for consistent interval execution - Fix pagination: count all entries (not just directories) for proper termination - Update lastFileName for all entries to prevent pagination issues * address PR comments: remove redundant atomic store, propagate context - Remove redundant atomic.StoreInt32 in StartLongLivedLock (AttemptToLock already sets it) - Propagate context through metrics collection for proper cancellation on shutdown - collectAndUpdateBucketSizeMetrics now accepts ctx - collectCollectionInfoFromMaster uses ctx for VolumeList RPC - listBucketNames uses ctx for ListEntries RPC |
