Timeseries InfluxDB

Description

Opsview Timeseries InfluxDB (opsview-timeseries-influxdb) provides a Timeseries storage framework. It consists of dedicated InfluxDB Updaters and Queries processes to maximize the throughput.

Note: This cannot be installed at the same time as opsview-timeseries-rrd.

Full details on setting up or migrating to the InfluxDB graphing engine can be found on Timeseries Graphing Engine.

InfluxDB Updaters

Opsview Timeseries InfluxDB Updaters launch a master management process that binds to the configured ports and launches that many worker processes each responsible for handling the requests for given port. That provides the guarantee that the data sent from Opsview Timeseries Enqueuer for a given host is handled by a single process only, thus removes the risk of processing the data out of order. The metadata (including the uoms) is stored in the SQlite3 database.

InfluxDB Queries

Opsview Timeseries InfluxDB Queries provide a way of querying the gathered performance metrics and listing them.

Dependencies

Opsview Timeseries InfluxDB can be installed on any supported platform. To reduce network traffic it is recommended to install it on the same host as the Opsview Timeseries Enqueuer component.

Prerequisites

You must separately install InfluxDB, unlike RRD it is not bundled with Opsview

# download package for your platform and follow the install documentation from InfluxDB
https://docs.influxdata.com/influxdb/v1.8/introduction/installation
  
# create a fresh Opsview database in InfluxDB
curl -i -XPOST http://127.0.0.1:8086/query --data-urlencode "q=CREATE DATABASE opsview"

Installation

Refer to Advanced Automated Installation.

Configuration

If opsview-timeseries-influxdb was installed on other then Opsview Timeseries or Timeseries Enqueuer host, you need to update the /opt/opsview/timeseriesinfluxdb/etc/timeseriesinfluxdb.yaml file to listen other than loopback interface.
