Scheduling

When

Quartz cron schedule http://www.quartz-scheduler.org/docs/tutorials/crontrigger.html 

currently implemented

Report Generation

Node filtering

all 

currently implemented; it's the default if a filter isn't specified

filter 

currently implemented; see FilterWalker

IP 

not currently implemented or planned

Resource filtering

resourceTypeMatch 

currently implemented (see ResourceTypeFilteringResourceVisitor). Use nodeSnmp when reporting on node level graphs and interfaceSnmp for interface level graphs. If the graph is stored at a location other than Node or Interface use the directory name that it is contained within.

resourceAttributeKey 

used with resourceAttributeValueMatch to perform an equality match on the value of an attribute on a resource (see ResourceAttributeFilteringResourceVisitor). E.g.: "ifSpeed" and "100000000" to match on 100 Mbps Ethernet interfaces for resources of the interfaceSnmp resource type.

resourceAttributeValueMatch 

used with resourceAttributeKey; see above.

Attribute filtering

attributeMatch 

currently implemented (see AttributeMatchingResourceVisitor)

Attribute value computation

consolidationFunction 

currently implemented (see RrdStatisticAttributeVisitor)

relativeTime 

currently implemented (see RrdStatisticAttributeVisitor). Valid values include: LASTTHIRTYONEDAYS, LASTSEVENDAYS, YESTERDAY, LASTHOUR.

Report type

class-name in a <report> definition 

currently implemented

Report-specific parameters

count 

see TopNAttributeStatisticVisitor

TopNAttributeStatisticVisitor creates statistics about the N largest values
BottomNAttributeStatisticVisitor create the smallest N values.
