## Note: This is an example of how to configure this feature
##       you should copy and paste the below data into the emqx.conf for working

sysmon.os {
    ## Time interval for the periodic CPU check
    cpu_check_interval = "60s"

    ## For how much system cpu can be used before the corresponding alarm is raised
    cpu_high_watermark = "80%"

    ## For how much system cpu can be used before the corresponding alarm is cleared
    cpu_low_watermark = "60%"

    ## Time interval for the periodic memory check
    ## Type:
    ##   - disabled :: Never check
    ##   - Time Duration :: The time period
    mem_check_interval = "60s"

    ## For how much system memory can be allocated before the corresponding alarm is raised
    sysmem_high_watermark = "70%"

    ## For how much system memory can be allocated by one Erlang process before the corresponding alarm is raised
    procmem_high_watermark = "5%"
