BLM3

Notice: The blm3 is replaced by taosadapter project and this repo is archived.

Function

  • Compatible with restful interface
  • Compatible with influxdb v1 write interface
  • Compatible with opentsdb json and telnet format writing
  • Seamless connection collectd
  • Seamless connection with statsd

Interface

restful

/rest/sql
/rest/sqlt
/rest/sqlutc

influxdb

/influxdb/v1/write

Support query parameters

db Specify the necessary parameters for the database precision time precision non-essential parameter u user non-essential parameters p password Optional parameter

opentsdb

/opentsdb/v1/put/json/:db
/opentsdb/v1/put/telnet/:db

collectd

Need to manually create database first collectd.db
Modify the collectd configuration /etc/collectd/collectd.conf

LoadPlugin network
<Plugin network>
         Server "127.0.0.1" "6045"
</Plugin>

statsd

Need to manually create database first statsd.db
statsd modify the configuration file path_to_statsd/config.js

  • backends add "./backends/repeater"

  • repeater add { host:'host to blm3', port: 6044}

example config

{
port: 8125
, backends: ["./backends/repeater"]
, repeater: [{ host: '127.0.0.1', port: 6044}]
}

icinga2 opentsdb writer

collect check result metrics and performance data

object OpenTsdbWriter "opentsdb" {
  host = "host to blm3"
  port = 6046
}

TCollector

tcollector is a client-side process that gathers data from local collectors and pushes the data to OpenTSDB. You run it on all your hosts, and it does the work of sending each host’s data to the TSD.

  • Need to manually create database first opentsdb_telnet.db
  • Enable blm3 configuration opentsdb_telnet.enable
  • Modify the TCollector configuration file, modify the opentsdb host to the host where blm is deployed, and modify the port to 6046

node_exporter

exporter for hardware and OS metrics exposed by *NIX kernels

  • Need to manually create database first node_exporter.db
  • Enable blm3 configuration node_exporter.enable
  • Set the relevant configuration of node_exporter
  • Restart blm3

Configuration

Support command line parameters, environment variables and configuration files Command line parameters take precedence over environment variables take precedence over configuration files The command line usage is arg=val such as blm3 -p=30000 --debug=true
