java.lang.Objectorg.opennms.netmgt.eventd.datablock.EventConfData
The information read from the eventconf.xml is stored here. It maintains a map, keyed with 'EventKey's. It also has an UEI to 'EventKey'list map - this mapping fastens the lookup for OpenNMS internal events when different masks are configured for the same UEI. When a lookup is to be done for an 'Event', - its 'key' is used to get a lookup, - if no match is found for the key, UEI is used to lookup the keys that got added for that UEI and the first best fit in the event map for any of the UEI keys are used - if there is still no match at this point, all keys in the eventconf are iterated through to find a match
Field Summary | |
private java.util.LinkedHashMap |
m_eventMap
The map keyed with 'EventKey's |
private java.util.LinkedHashMap |
m_ueiToKeyListMap
The map of UEI to 'EventKey's list - used mainly to find matches for the OpenNMS internal events faster(in cases where there are multiple masks for the same UEI) |
Constructor Summary | |
EventConfData()
Default constructor - allocate the maps |
Method Summary | |
void |
clear()
Clear out the data |
private void |
dumpEventMap()
Purely used for debugging |
private boolean |
eventMatchesKey(EventKey eventKey,
Event event)
Check whether the event matches the passed key |
private boolean |
eventValuePassesMaskValue(java.lang.String eventvalue,
java.util.List maskValues)
Check whether the eventvalue passes any of the mask values Mask values ending with a '%' only need to be a substring of the eventvalue for the eventvalue to pass the mask |
Event |
getEvent(Event event)
Get the right configuration for the event - the eventkey is used first. |
Event |
getEventBySnmp(java.lang.String eid)
Get the event with the specified snmp key |
Event |
getEventByUEI(java.lang.String uei)
Get the event with the specified uei |
private Event |
getMatchInKeyList(java.util.List keylist,
Event event)
See if there is a match for the event from the list of event keys |
void |
put(Event event)
Add an event - add to the 'EventKey' map using the event mask by default. |
void |
put(EventKey key,
Event event)
Add an event with the specified key |
private void |
updateUeiToKeyListMap(EventKey eventKey,
Event event)
Update the uei to keylist map |

Get the right configuration for the event - the eventkey is used first. If no match is found, the event's uei to keylist is iterated through, and these keys used to lookup the event map. if still no match is found, all eventconf keys are iterated through to find a match. The first successful match is returned. NOTE: The first right config event that the event matches is returned. The ordering of the configurations is the responsibility of the user
