New in version 0.6.
Graphs the Heka memory statistics using the heka.memstat message generated by pipeline/report.go.
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.
Sets the size of each bucket (resolution in seconds) in the sliding window.
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
[HekaMemstat] type = "SandboxFilter" filename = "lua_filters/heka_memstat.lua" ticker_interval = 60 preserve_data = true message_matcher = "Type == 'heka.memstat'"
