© 2009 GroundWork Open Source, Inc. Page 11 Key Definitions Introduction to GroundWork Monitor Enterprise Edition
© 2009 GroundWork Open Source, Inc. Page 12 Hosts – A server, workstation, or device for which the availability status is to be tracked or mapped (e.g. localhost). Services – A monitor or check of a particular parameter/status associated with a Host (e.g. Current Load). Host Groups – An arbitrary collection of Hosts into named sets (e.g. Linux Servers) State – The condition of Services and Hosts (e.g. UP, DOWN and OK, CRITICAL or WARNING for services). State Change – Soft - the system retries a service check a programmable number of times; and Hard - the retries have been exceeded. Monitoring Terminology Key Definitions
© 2009 GroundWork Open Source, Inc. Page 13 Contacts, and Contact Groups – Contacts identify who should receive alert/recovery notifications in the event of a problem on your network; Contact Groups are groupings of one or more contacts. Notifications and Escalations –Communications to Contacts or Contact Groups for any hard state change, hosts or service remaining in non-OK state, and acknowledgements. Flapping – Frequent changes in state, resulting in a storm of alarm and recovery notifications. GroundWork Monitor can be configured to suppress alarms during flapping. Downtime – Scheduling downtime avoids alarm fatigue, provides more accurate reports, generates a maintenance log.. Dependencies – When a monitored item is not on the same subnet as the monitoring server, monitoring is dependent upon the intervening switches and routers. Monitoring Terminology Key Definitions
© 2009 GroundWork Open Source, Inc. Page 14 States of Hosts Nagios assigns a State to each Host and Service Hosts either respond to a Host Check (typically a ping) or they don’t Based on this, the primary States for a host are UP or DOWN In addition, if a Host is behind a known network outage it will be given State of UNREACHABLE UP DOWN UNREACHABLE Host States Key Definitions Monitoring Terminology
© 2009 GroundWork Open Source, Inc. Page 15 States of Services Services are compared against acceptability thresholds and have three states (OK, WARNING & CRITICAL) If a measured parameter in a service is less than the WARNING threshold it returns a State of OK If that parameter exceeds the WARNING threshold but is less than the CRITICAL threshold it returns WARNING If that parameter exceeds the CRITICAL threshold it returns a State of CRITICAL Thresholds can be more complex than this example and contain multiple parameters If the service is configured incorrectly (i.e. bad arguments) return can be UNKNOWN OK WARNING CRITICAL UNKNOWN Service StatesPlugin Errors Key Definitions Monitoring Terminology

Key Definitions Monitoring Terminology
© 2009 GroundWork Open Source, Inc. Page 17 There are five kinds of dependency relationships Network dependencies exist between devices and their upstream parents (defined using the parents directive) Example: A host can depend on an upstream switch One host can depend on another host somewhere in the network (defined using the host_dependency directive) Example: A web server can depend on a load balancer A service on one host can depend on a service on another host (service_dependency directive) Example: An Application server’s speed can depend on a Database server’s query response time Services can depend on other services on the same server (defined using the service_dependency directive) Example: An snmp check can depend on the snmpd running on the same server Services have an inherent dependency on the server upon which they run Key Definitions Monitoring Terminology
