Icinga Camp Belgrade - ITAF Monitoring best practices & demo
1 like2,972 views
ITAF's approach to monitoring involves customized implementations using tools like Icinga, Cacti, NagVis, and Dashing to provide real-time monitoring, performance and capacity graphing, dashboards, reporting, and templates. The infrastructure is designed for an easy to manage view with only actual issues, straightforward configuration, and no false positives. Monitoring operations follow a process of proactive monitoring, acknowledgements, incident resolution, improvements, and threshold tuning.
Icinga Camp Belgrade - ITAF Monitoring best practices & demo
- 2. Monitoring, uuuuh? Monitoring? ITAF’s approach to good practice monitoring A walkthrough the ITAF monitoring infrastructure Demo
- 3. Monitoring? To monitor ~ to listen to (transmitted signals) on a receiving set in order to check the quality of the transmission. to view or listen to (television or radio transmissions) in order to check the quality of the video or audio. to listen to (a radio conversation or channel); keep tuned to. to observe, record, ordetect to oversee, supervise, or regulate: to watch closely forpurposes of control, surveillance, etc.; keep trackof; checkcontinually:
- 4. Monitoring requirements vs issues? Plug & play Easy to implement Deliver multi-vendor support Not flexible Difficult to maintain Always too many alerts to handle (Christmas tree effect)
- 6. Monitoring goals An easy to manage view, with only actual issues Straightforward configuration No false positives
- 7. ITAF’s approach to good practice monitoring
- 8. ITAF’s approach to good practice monitoring Tooling Customized implementation (vs plug & play) Customized views for users / customers Customized notifications (sms, mail, IM,…) Everything which can be queried can be monitored Automated reporting
- 9. ITAF’s approach to good practice monitoring Monitoring operations (event management) Proactive monitoring (warning / critical) Acknowledgements Solve the incident (incident management) Implement an improvement (improvement management) Fine tune monitoring thresholds Schedule downtime (change management)

- 11. A walk-through of the ITAF monitoring infrastructure Realtime monitoring Performance & capacity graphing Dashboards & reporting Templates & procedures
- 12. Realtime monitoring – Some history ● Shouting customers :-) (1999 – 2005) ● Nagios – Lilac (2005 – 2011) ● Icinga 1 – NagiosQL (2011 – 2015) ● Icinga 1 – Lconf (2015 – now) ● Icinga 2 – Icinga Director (2017)
- 13. Realtime monitoring? Icinga! Icinga 1 – Classic UI – Icingaweb2 5 worker servers using mod_gearman A redundant pair of database servers using DRBD
- 15. Performance & Capacity graphing - Cacti Cacti is a complete network graphing solution designed to harness the power of RRDTool's data storage and graphing functionality.
- 16. Dashboards & reporting NagVis is a visualization addon for both Icinga and Nagios NagVis can be used to visualize monitoring Data, e.g. to display IT processes like a mail system or a network infrastructure.
- 17. Dashboards & reporting Dashing “The exceptionally handsome dashboard framework.”
- 18. Reporting JasperReports InGraph Performance data What we use? Scripted IP SLA reporting - Automation - Integration - Easy to use and adjust
- 19. Templates & Procedures Heavy use of templates – makes things easy Inheritance of properties via templates Nagstamon – filtering of .*staging Nagstamon – using IcingaWeb2 to reduce load on the Core server Strict Code of Conduct to prevent avoidable alarms

- #4: Dieter
- #8: Momcilo Policy to answer all requirement mentioned. How to achieve mentioned goals?
- #9: Customization brings greater integration but requires planning Combining everything in single monitoring to achieve perfection and avoid fragmentation of attention.
- #10: Each level should indicate what approach to take Acknowledging working in cleanup purpose Downtime to prepare for known issues and changes

- #18: Momo
- #20: Greatest power of templates is inheritance Easily configure multitude of hosts Add things to staging to avoid disruption of others Icinga Web2 talks to database Code of conduct enforces set of behavioral rules to prevent all unwanted monitoring issues.
