Grafana + InfluxDB

Introduction

In order to monitor the HELIOS system, for example, the threshold, the tigger rate, the buffer size, etc. We monitor and save those data into a database managed by InfluxDB. The database is further read by Grafana for display.

For more information on InfluxDB and Grafana, see:

InfluxDB documentation

Grafana

Present setting

The data (e.g. trigger Rate, threshold, Buffer ) must be taking in digios1, the DAQ.

Since the DAQ is running on a 32-bit system. the influxDB is unstable.

The database was installed in heliosDB.onenet.

Thus, the data will be push to heliosDB.

Grafana was also installed in heliosDB.

Setup InfluxDB

For 64bit-linux, the setup is straight forward.

For example, in Ubuntu-18.x, simply type

sudo apt-get install influxdb

The influxdb contains 2 main programs,

1. influx, for interactive database operations
2. influxd, a daemon run in background, for receiving query from port 8086

To run the influxd

sudo service influxdb start

Present setting

The bash script in ~/digios/daq/edm/script/helios_database
