Input Plugin: InfluxDB

Receives metrics from InfluxDB compatible agents like telegraf. Logagent behaves like InfluxDB HTTP API /write endpoint. Metrics are converted from influx-line-protocol to a JSON structure. The JSON documents could be indexed in Elasticsearch or Sematext Cloud - or forwarded to any other output plugin.

Example

# Logagent configuration file: influx.yml
input:
  influxDb: 
    module: input-influxdb-http
    port: 8086
    workers: 1

output: 
  stdout: yaml 
  # sematext-cloud:
  #   module: elasticsearch 
  #   url: https://logsene-receiver.sematext.com
  #   index: YOUR_LOGSENE_TOKEN_HERE

Run Logagent

logagent --config influxdb.yml 

Then start e.g. Telegraf configured for InfluxDB, pointing to Logagent server.

# Telegraf configuration 
# Configuration for influxdb server to send metrics to Logagent
[[outputs.influxdb]]
  ## The HTTP or UDP URL for your InfluxDB instance.  Each item should be
  ## of the form:
  ##   scheme "://" host [ ":" port]
  ##
  ## Multiple urls can be specified as part of the same cluster,
  ## this means that only ONE of the urls will be written to each interval.
  # urls = ["udp://localhost:8089"] # UDP endpoint example
  urls = ["http://logagent-server-name:8086"] # required
  ## The target database for metrics (telegraf will create it if not exists).
  database = "telegraf" # required

Logagent would output metrics received from Telegraf agent (YAML):
