rebar compile
- report_mf:
Reporting module and function for the fun/1 that will report the iolist describing the system statistics. Defaults to
`{ehmon, stdout_report}`
.Reports can also be sent to shh using
`{ehmon_shh_report, send_report}`
. If you decide to send reports to a listening shh instance you must decide to use either a TCP or Unix Domain Socket. Using the domain socket interface will require an additional dependency on gen_unix <https://github.com/msantos/gen_unix>_. You wil need to add it accordingly to your applications`rebar.config`
or similar file.- report_interval:
- Interval in seconds between outputing the report. Defaults to
`60`
. - shh_report_prefix:
- The prefix to prepend to report statistics. Defaults to
`"erlang.ehmon"`
. - shh_connection:
- A string that specifies how to connect to the listening shh process. The string should match on of the following
two formats:
`tcp,$HOST:$PORT`
or`unix,$PATH_TO_SOCKET`
.
