Methods

Protected getCount

  • getCount(data: any): number

  • A convenience method to make it easy for implementers to extract the count (or totalCount) values from response data.

    Parameters

    • data: any

    Returns number

getExporter

  • getExporter(criteria: string, limit: number, start?: number, end?: number): Promise<OnmsFlowExporter>

  • Get detailed information about a specific node.

    Parameters

    • criteria: string

      the node ID or foreignSource:foreignId tuple

    • limit: number

      maximum number of interfaces to return (those with the most flows will be returned if the results are truncated)

    • Optional start: number

      the start of the timespan to query (defaults to 4 hours ago)

    • Optional end: number

      the end of the timespan to query (defaults to now)

    Returns Promise<OnmsFlowExporter>

getExporters

  • Get a summary of the nodes that have exported flows.

    Parameters

    • limit: number

      maximum number of exporters to return (those with the most flows will be returned if the results are truncated)

    • Optional start: number

      the start of the timespan to query (defaults to 4 hours ago)

    • Optional end: number

      the end of the timespan to query (defaults to now)

    Returns Promise<OnmsFlowExporterSummary[]>

getSeriesForTopNApplications

  • getSeriesForTopNApplications(N?: number, start?: number, end?: number, step?: number, includeOther?: boolean, exporterNodeCriteria?: string, ifIndex?: number): Promise<OnmsFlowSeries>

  • Get time series data for the top N applications/protocols based on parameters.

    Parameters

    • Optional N: number

      how many applications' series to return

    • Optional start: number

      the start of the timespan to query (defaults to 4 hours ago)

    • Optional end: number

      the end of the timespan to query (defaults to now)

    • Optional step: number

      the requested time interval between rows

    • Optional includeOther: boolean

      include an additional "other" result that represents everything that does not match the top N

    • Optional exporterNodeCriteria: string

      the node ID or foreignSource:foreignId tuple

    • Optional ifIndex: number

      filter for flows that came through this SNMP interface

    Returns Promise<OnmsFlowSeries>

getSeriesForTopNConversations

  • getSeriesForTopNConversations(N?: number, start?: number, end?: number, step?: number, exporterNodeCriteria?: string, ifIndex?: number): Promise<OnmsFlowSeries>

  • Get time series data for the top N conversations based on parameters.

    Parameters

    • Optional N: number

      how many conversations' series to return

    • Optional start: number

      the start of the timespan to query (defaults to 4 hours ago)

    • Optional end: number

      the end of the timespan to query (defaults to now)

    • Optional step: number

      the requested time interval between rows

    • Optional exporterNodeCriteria: string

      the node ID or foreignSource:foreignId tuple

    • Optional ifIndex: number

      filter for flows that came through this SNMP interface

    Returns Promise<OnmsFlowSeries>

getSummaryForTopNApplications

  • getSummaryForTopNApplications(N?: number, start?: number, end?: number, includeOther?: boolean, exporterNodeCriteria?: string, ifIndex?: number): Promise<OnmsFlowTable>

  • Summarize the top N applications/protocols based on parameters.

    Parameters
