Types

type CacheMetrics 

type CacheMetrics struct {
	SizeVec *prometheus.GaugeVec
	GetVec  *prometheus.CounterVec
	AddVec  *prometheus.CounterVec
}

CacheMetrics implements the Metrics interface in the caching package, implementing reusable metrics for different caches.

func NewCacheMetrics 

func NewCacheMetrics(factory metrics.Factory, ns string, name string, displayName string) *CacheMetrics

func (*CacheMetrics) CacheAdd 

func (m *CacheMetrics) CacheAdd(typeLabel string, typeCacheSize int, evicted bool)

CacheAdd meters the addition of an item with a given type to the cache, metering the change of the cache size of that type, and indicating a corresponding eviction if any.

func (*CacheMetrics) CacheGet 

func (m *CacheMetrics) CacheGet(typeLabel string, hit bool)

CacheGet meters a lookup of an item with a given type to the cache and indicating if the lookup was a hit.

Metrics tracks all the metrics for the op-node.

func NewMetrics 

func NewMetrics(procName string) *Metrics

NewMetrics creates a new Metrics instance with the given process name.

func (*Metrics) CountSequencedTxs 

func (m *Metrics) CountSequencedTxs(count int)

func (*Metrics) DecPeerCount 

func (m *Metrics) DecPeerCount()

func (*Metrics) DecStreamCount 

func (m *Metrics) DecStreamCount()

func (*Metrics) Document added in v0.10.11 

func (m *Metrics) Document() []metrics.DocumentedMetric

func (*Metrics) IncPeerCount 

func (m *Metrics) IncPeerCount()

func (*Metrics) IncStreamCount 

func (m *Metrics) IncStreamCount()

func (*Metrics) RecordBandwidth 

func (m *Metrics) RecordBandwidth(ctx context.Context, bwc *libp2pmetrics.BandwidthCounter)

func (*Metrics) RecordDerivationError 

func (m *Metrics) RecordDerivationError()

func (*Metrics) RecordGossipEvent 

func (m *Metrics) RecordGossipEvent(evType int32)

func (*Metrics) RecordInfo 

func (m *Metrics) RecordInfo(version string)

RecordInfo sets a pseudo-metric that contains versioning and config info for the opnode.

func (*Metrics) RecordL1Ref 

func (m *Metrics) RecordL1Ref(name string, ref eth.L1BlockRef)

func (*Metrics) RecordL1ReorgDepth 

func (m *Metrics) RecordL1ReorgDepth(d uint64)

func (*Metrics) RecordL2Ref 

func (m *Metrics) RecordL2Ref(name string, ref eth.L2BlockRef)

func (*Metrics) RecordPipelineReset 

func (m *Metrics) RecordPipelineReset()

func (*Metrics) RecordPublishingError 

func (m *Metrics) RecordPublishingError()

func (*Metrics) RecordRPCClientRequest 

func (m *Metrics) RecordRPCClientRequest(method string) func(err error)

RecordRPCClientRequest is a helper method to record an RPC client request. It bumps the requests metric, tracks the response duration, and records the response's error code.

func (*Metrics) RecordRPCClientResponse 

func (m *Metrics) RecordRPCClientResponse(method string, err error)

RecordRPCClientResponse records an RPC response. It will convert the passed-in error into something metrics friendly. Nil errors get converted into <nil>, RPC errors are converted into rpc_<error code>, HTTP errors are converted into http_<status code>, and everything else is converted into <unknown>.

func (*Metrics) RecordRPCServerRequest 

func (m *Metrics) RecordRPCServerRequest(method string) func()

RecordRPCServerRequest is a helper method to record an incoming RPC call to the opnode's RPC server. It bumps the requests metric, and tracks how long it takes to serve a response.

func (*Metrics) RecordReceivedUnsafePayload 

func (m *Metrics) RecordReceivedUnsafePayload(payload *eth.ExecutionPayload)

func (*Metrics) RecordSequencerBuildingDiffTime added in v0.10.4 

func (m *Metrics) RecordSequencerBuildingDiffTime(duration time.Duration)

RecordSequencerBuildingDiffTime tracks the amount of time the sequencer was allowed between start to finish, incl. sealing, minus the block time. Ideally this is 0, realistically the sequencer scheduler may be busy with other jobs like syncing sometimes.

func (*Metrics) RecordSequencerSealingTime added in v0.10.4 

func (m *Metrics) RecordSequencerSealingTime(duration time.Duration)

RecordSequencerSealingTime tracks the amount of time the sequencer took to finish sealing the block. Ideally this is 0, realistically it may take some time.

func (*Metrics) RecordSequencingError 

func (m *Metrics) RecordSequencingError()

func (*Metrics) RecordUnsafePayloadsBuffer 

func (m *Metrics) RecordUnsafePayloadsBuffer(length uint64, memSize uint64, next eth.BlockID)

func (*Metrics) RecordUp 

func (m *Metrics) RecordUp()

RecordUp sets the up metric to 1.

func (*Metrics) Serve 

func (m *Metrics) Serve(ctx context.Context, hostname string, port int) error

Serve starts the metrics server on the given hostname and port. The server will be closed when the passed-in context is cancelled.

func (*Metrics) SetDerivationIdle 

func (m *Metrics) SetDerivationIdle(status bool)
