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:
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 or heliosDB.
Thus, the data will be push to heliosDB.
To run the monitor program, login to the DAQ (digios1.onenet)
digios1$ Helios_Database Start
To stop the monitor program,
digios1$ Helios_Database Stop
Grafana was also installed in heliosDB.
To run Grafana, from any browser, within onenet, type
http://heliosDB.onenet:3000
if no webpage found, probably the Grafana server is not started. To start the Grafana server
sudo service grafana-server start
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,
- influx, for interactive database operations
- influxd, a daemon run in background, for receiving query from port 8086
To run the influxd
sudo service influxdb start
Setup Grafana
sudo apt-get update sudo apt-get install grafana
Or see Grafana webpage, straight forward.
SSH Tunneling to heliosDB from outside
Since the Grafana is installed in heliosDB inside onenet. There is no simple way to check the Grafana from outside.
One solution is using sonata.phy.anl.gov via ssh tunneling.
ssh -nNT -L 9000:heliosdb.onenet:3000 <username>@sonata
The above ssh command is using sonata, port-forwarding heliosdb.onenet:3000 to localhost:9000.
After typing this in terminal, use any browser, type http://heliosDB.onenet:3000
