This presentation discusses tools for automating database operations and monitoring databases. It introduces Ansible for automation, and Telegraf, Influxdb, Grafana, Logstash, Elasticsearch, Kibana, and Kapacitor for collecting, storing, and visualizing metrics, logs, and alerts. The presentation includes a live demo of using these tools to provision an Oracle database, create performance dashboards, generate alerts, and view logs and audits. The goal is to provide a modern, agile approach to database administration.

3. Challenge
3
• DBaaS with automation for:
• Software installation
• Database creation
• Patching
• Upgrade
• Standby creation

4. Challenge
4
• End user should access performance dashboards
• End user should access logs
• Security Team should access audit and logs
• Monitoring and alerting
• Same toold for all SGBD (oracle, postgres, mssql)

5. Tools
5
• Ansible for automation
• Telegraf, Influxdb and grafana to collect, store and
display performance metrics
• Logstash, elasticsearch and kibana to collect, store
and display logs and audit
• Kapacitor for monitoring and alerting

6. What is this presentation about?
6
• Brief overview of Ansible
• Brief overview of Telegraf, Influxdb and grafana
• Brief overview of Logstash, elasticsearch and kibana
• Brief overview of Kapacitor for monitoring and
alerting
• Live demo

7. What this presentation is not?
7
• In depth overview of Ansible
• In depth overview of Telegraf, Influxdb and grafana
• In depth overview of Logstash, elasticsearch and
kibana
• In depth overview of Kapacitor for monitoring and
alerting

8. Ansible
8
• Ansible is a radically simple IT automation engine
• it uses no agents
• it's easy to deploy
• it uses a very simple language (YAML, in the form
of Ansible Playbooks)

9. Telegraf, Influxdb, Kapacitor
and Grafana
9
• Telegraf is a plugin-driven server agent for collecting and reporting
metrics
• Telegraf has integrations to source a variety of metrics, events, and
logs
• InfluxDB is used as a data store for time-stamped data
• Kapacitor can process both stream and batch data from InfluxDB. It lets
you plug in your own custom logic or user-defined functions to process
alerts with dynamic thresholds, match metrics for patterns, compute
statistical anomalies, and perform specific actions based on these
alerts
• Grafana allows you to query, visualize, alert on and understand your
metrics

and Grafana

11. Logstash, Elasticsearch and Kibana
11
• Logstash is an open source, server-side data
processing pipeline that ingests data from a
multitude of sources simultaneously, transforms it,
and then sends it to your favorite “stash.”
• Elasticsearch is a distributed, RESTful search and
analytics engine (lucene)
• Kibana lets you visualize your Elasticsearch data

13. DBaaS
13
• Let’s prepare the system
• Let’s install the 12.1.0.2 software
• Let’s create a 12.1.0.2 database

14. Performance dashboards
14
• Telegraf is installed
• Influxdb exists
• Grafana exists
• Let’s deploy telegraf configuration files
• Let’s generate some load (SLOB)
• Let’s see the performance dashboard

15. Alerting
15
• Telegraf configuration files are deployed
• Kapacitor is installed
• Let’s deploy Kapacitor configuration files
• Let’s see the alerts

16. Logs and Audit
16
• Elasticsearch exists
• Kibana exists
• Let’s deploy logstash
• Let’s generate some activity (logon, stop/start, ORA-)
• Let’s see the kibana dashboard
