We shift our focus to true incident management and start the next
transition of Icinga. Notifications move into the center of monitoring.

67. Our Goals
• Simplified contacts management
• Duty management (on-call)
• Well maintained notification channels
• Central hub for notifications

68. Teamwork Manager
Ensure good communication processes
and efficient workflows.
• Enhanced management for Contacts and Groups
• Define and apply escalation rules
• Assign teams to specific parts of your infrastructure
• Finally define channels and recipients

74. Channel Genius
• Pick any notification channel you like. Icinga
impresses with flexibility towards integrations.
• Ticketing systems
• Platforms like PagerDuty, OpsGenie or ServiceNow
• SMS, Slack, Telegram and other messengers

75. Where do we go
from there?

76. Next Steps
• Preview release by the end of this year
• Collect feedback
• 1.0 release next year
• First notifications channels right after the first release

78. Open Topics
• High Availability
• Attach AD/LDAP
• Incident aggegration
• Upgrade modules step by step

79. Kubernetes
Monitoring very dynamic infrastructures

80. Traditional Approaches
• Hosts
• Bare metal, virtual machines
• Cloud instances to some extent
• Services
• Resource usage
• Applications, …
• Check Plugins
• Alerts

81. Traditional Approaches
• Automation
• Configuration Management
• Director
• Icinga APIs
• Metrics

84. K8s Monitoring– What?
• Hosts (where K8s components run)
• K8s itself
• Services, e.g. Deployments, *Sets, Jobs
• Pods and Containers
• Key metrics
Not only infrastructure but also workloads

85. K8s Monitoring – Complexity
• Loads of resource types
• Multiple components and layers
• Different failure points
• Understanding of the entire stack
Via hosts, services and check plugins?

86. K8s Monitoring – Challenges
Run
Fail
Respaw
n
Run
Fail
....

87. K8s Monitoring – Probes
Liveness probes periodically check container liveness and
restart containers that fail it.
Readiness probes indicate container readiness and remove
failing ones from their service endpoints.
Startup probes defer the execution of liveness and readiness
probes and restarts containers that fail it.

88. K8s Monitoring – Approaches
• Poll K8s APIs
• Agent per node via DaemonSet
• Agent per pod (sidecar container)
• Events
• Metrics
• Logs
• APM

89. Possible K8s Metric Sources
• Node metrics from Prometheus node exporter
• Container metrics from cAdvisor (or metrics-server)
• K8s metrics
• API server
• etcd
• scheduler
• controller manager
• kube-state-metrics

91. Monitoring Kubernetes
with Icinga

92. Icinga K8s Monitoring
• Collects K8s resources and their
• Health
• Events
• Metrics
• Logs
• Visualizes K8s resources and hierarchies

93. Icinga K8s Monitoring Architecture

94. Icinga K8s Monitoring Architecture
• Icinga Web Module (PHP)
• View resources and hierarchies
• Daemon (Go)
• Collect resources, health, events,
logs and certain metrics
• Send alerts via Icinga Notifications
• Database
• Stores resources, health, …
