metric collector for influxdb

metricd - metric collector for influxdb

This is a simple metric collector service which was built for me personal needs. Only InfluxDB is supported as a data storage backend. The following modules are available for metric aggregation:

Mikrotik RouterOS Accounting

This modules uses the accounting functionality of Mikrotiks RouterOS. It provides per client traffic statistics. The clients ip adddress is stored as the tag host.

[accouting.test]
database = "db"                 # influx database name
measurement = "measurement"     # influx measurement name
sample_time = 1000              # sample time in ms
host = "192.168.178.1"          # router os host ip address
network = "192.168.178.0/24"    # network to obtain traffic stats from

MySQL

The MySQL module can be used to execute arbitrary SQL queries against an mysql server and store the results. The queries are executed every sample_time milliseconds.

[mysql.test]
database = "database"                                   # influx database name
measurement = "measurement"                             # influx measurement name
sample_time = 60000                                     # sample time in ms
sql_uri = "user:pass@tcp(127.0.0.1:3306)/database"      # database uri
queries = [                                             # query with value name
        "val1:SELECT AVG(time) FROM table",
        "val2:SELECT count(*) FROM table",
]
tags = ["foo:bar"]                                      # static tags

Syslog

The syslog module creates an RFC3164 compatible syslog server and parses the log messages with a standard golang regex. Named capture groups with the prefix tag_ are stored as tags and capture groups with the prefix val_ are parsed as float numbers and stored as point values.

[syslog.test]
database = "database"                   # influxdb database name
measurement = "measurement"             # influxdb measurement name
listen = "0.0.0.0:514"                  # listen address for syslog server
regex = "(key:\\s+(?P<val_value>.+)"    # regex to parse log message
tags = ["foo:bar"]                      # static tags

SNMP

Cyclically acquires information from an SNMP target.

[snmp.test]
host = "1921.68.178.1"
community = "public"
database = "database"
measurement = "measurement"
sample_time = 1000
tags = ["foo:bar"]
datapoints = [
	".1.3.6.1.2.1.31.1.1.1.10.1:tx_bytes",
	".1.3.6.1.2.1.31.1.1.1.6.1:rx_bytes",
