Heka Memory StatisticsΒΆ

New in version 0.6.

Plugin Name: SandboxFilter
File Name: lua_filters/heka_memstat.lua

Graphs the Heka memory statistics using the heka.memstat message generated by pipeline/report.go.


  • rows (uint, optional, default 1440)

    Sets the size of the sliding window i.e., 1440 rows representing 60 seconds per row is a 24 sliding hour window with 1 minute resolution.

  • sec_per_row (uint, optional, default 60)

    Sets the size of each bucket (resolution in seconds) in the sliding window.

  • anomaly_config (string, optional)

    See Anomaly Detection Module.

  • preservation_version (uint, optional, default 0)

    If preserve_data = true is set in the SandboxFilter configuration, then this value should be incremented every time the rows or sec_per_row configuration is changed to prevent the plugin from failing to start during data restoration.

Example Heka Configuration

type = "SandboxFilter"
filename = "lua_filters/heka_memstat.lua"
ticker_interval = 60
preserve_data = true
message_matcher = "Type == 'heka.memstat'"
