Configuration file

This is the default mfsysmon configuration file.

```ini

STARTUP

[startup]

If flag=0, block the start of the module

flag=1

AUTORESTART

[autorestart]

If flag=1, then the autorestart feature is on

flag=1

MISC

[misc]

Max coredumps size (value for ulimit -c;

if core_size=-1, ulimit -c is not set)

core_size=0

tmp sub-directory (${MFMODULE_RUNTIME_HOME}/tmp) cleaning

0 => no automatic cleaning

x => clean files/directories older than x days

tmp_max_age=2

LOG

[log]

Log minimal level

DEBUG => everything,

INFO => everything but not DEBUG,

WARNING => everything but not DEBUG and INFO,

ERROR => everything but not DEBUG, INFO and WARNING,

CRITICAL => everything but not DEBUG, INFO, WARNING AND ERROR

minimal_level=INFO

Duplicate some log messages in JSON to a specific file (for external

monitoring tool)

If json_file value is :

null => the feature is desactivated

AUTO => the feature is desactivated (because it's not necessary anymore

since 1.2 version)

json_file=null

Minimal level for this json log file

DEBUG => everything,

INFO => everything but not DEBUG,

WARNING => everything but not DEBUG and INFO,

ERROR => everything but not DEBUG, INFO and WARNING,

CRITICAL => everything but not DEBUG, INFO, WARNING AND ERROR

Note: you can't send more messages to json log file than the configured global

minimal_level level (so also change the value of minimal_level key in

these uncommon use-cases)

json_minimal_level=WARNING

Send some log files to mfadmin

null => the feature is desactivated

AUTO => the feature is activated if [admin]/hostname != null

mfadmin_flag=AUTO

Minimal level for mfadmin send

DEBUG => everything,

INFO => everything but not DEBUG,

WARNING => everything but not DEBUG and INFO,

ERROR => everything but not DEBUG, INFO and WARNING,

CRITICAL => everything but not DEBUG, INFO, WARNING AND ERROR

Note: you can't send more messages to mfadmin than the configured global

minimal_level level (so also change the value of minimal_level key in

these uncommon use-cases)

mfadmin_minimal_level=WARNING

Maximum number of rotated files to keep

number_of_rotated_files=5

Max age of a log file before rotation (in seconds)

Default: 86400 (24H)

max_age_before_rotation=86400

Max size of a log file before rotation (in bytes)

Default: 104857600 (100 MB)

max_size_before_rotation=104857600

chmod on log files

Default : 0644

chmod=0644

Try to split stdout/stderr in distinct log files (when it's possible)

(1 => split, 0 => don't split)

try_to_split_stdout_stderr=0

Try to split multiple workers in distinct log files (when it's possible)

(1 => split, 0 => don't split)

try_to_split_multiple_workers=0

VECTOR

[vector]

UDP port used by vector syslog server (for mflog logs)

mflog_port = 5147

ADMIN MODULE

[admin]

Hostname hosting the mfadmin module (if any)

null => no monitoring

localhost => send logs and metrics to the locally installed mfadmin module

* => send logs and metrics to the specified host (which must host an mfadmin

module)

hostname=localhost

Influxdb HTTP port on mfadmin host

(change this only if you changed influxdb http port on mfadmin host)

influxdb_http_port=18086

ElasticSearch HTTP port on mfadmin host

(change this only if you changed elasticsearch http port on mfadmin host)

(0 => no elasticsearch usage)

elasticsearch_http_port=15603

Loki HTTP port on mfadmin host

(change this only if you changed loki http port on mfadmin host)

(0 => no loki usage)

(13600 => default loki http port on mfadmin)

loki_http_port=0

If send_mflog_logs=1, send mflog logs to the configured admin hostname

send_mflog_logs=1

TELEGRAF

[telegraf]

If debug=1, all metrics are (also) dumped into telegraf.log file

debug=0

UDP port to listen for statsd protocol

see https://github.com/influxdata/telegraf/tree/master/plugins/inputs/statsd

statsd_port=18129

If you want to use mfsysmon telegraf as a collector for external

(ie. non-metwork) metrics, you can use this to listen to a particular port

in TCP or UDP

null => no specific listening

tcp4://:8094 => listen to TCP port 8094

udp4://:8094 => listen to UDP port 8094

see https://github.com/influxdata/telegraf/tree/master/plugins/inputs/socket_listener

for details

external_service_address=null

If you want to use mfsysmon telegraf as a collector for external

(ie. non-metwork) metrics, you can use this to execute some custom commands

to collect external things

see https://github.com/influxdata/telegraf/tree/master/plugins/inputs/exec

(the data_format is set to influx, the timeout is set to 10s and the name_suffix

is set to _custom)

you can provide a coma separated list of commands full paths

(null => no external commands)

(example: /usr/local/bin/mycollector1 --foo=bar,/usr/local/bin/mycollector2)

external_commands=null

CIRCUS

[circus]

You probably don't want to change anything in this section

endpoint=ipc://{{MFMODULE_RUNTIME_HOME}}/var/circus.socket pubsub_endpoint=ipc://{{MFMODULE_RUNTIME_HOME}}/var/circus_pubsub.socket

Arbiter config setting (default 5 was not enough to prevent "ConflictError: arbiter is already running..." with circus 0.17.2

check_delay = 15
