In presentation, I introduced the basics of the InfluxDB and Grafana bundle. A brief introduction about these tools.

1. InfluxDB & Grafana
Caner Ünal

2. InfluxDB
● Time-based database
● Schemaless design
● HTTP API support
● InfluxQL - Similiar to SQL
● Storage part of the TICK stack
❖ Telegraf
❖ InfluxDB
❖ Chronograf
❖ Kapacitor

3. Time-Series Data
● Real-Time Analytics
● Custom Monitoring
● IoT and Sensor Data
● Openstack, Docker and Virtualization

4. Key Concepts
Line Protocol
Database Measurement
Tag Field Timestamp

5. Data Import
● InfluxDB web interface + command line
● HTTP API
Command or text files.
● HTTP API Client Libraries
We use an Asp.Net library.

6. measurement, tkey=tvalue, tkey2=tvalue2... fkey=fvalue
Write Syntax

7. Performance
● Decide a variable whether tag or field is important.
Series Cardinality : The number of unique measurement and tag set
combinations in an instance. When tag values are dependent they don't
increase cardinality at all
● Retention Policy and Continuous Queries
Continuous Query: An InfluxQL query that runs automatically and periodically
within a database.

9. Grafana
● Querying and Visualizing time series and metrics
● Supports InfluxDB, Elasticsearch, Cloudwatch, Prometheus, Graphite
● Plugins can be installed
