"KLEVP_EVENT_PRODUCT"	paramString	Product name *.
"KLEVP_EVENT_INTERNAL_VERSION"	paramString	Product version name *.
"KLEVP_EVENT_DISPLAY_VERSION"	paramString	Product build.

"EVP_INCL_GNRL_EVENTS"	paramBool	Include general and specific product events. False by default. If set to true for a local task history, the parameters "KLEVP_EVENT_TASK_NAME" and "KLEVP_EVENT_PRODUCT" must be also set.
"EVP_INCL_TASK_STATES"	paramBool	Include events on task states changes; optional; false by default.
"KLEVP_EVENT_TYPE"	paramString	Name of the event type. For example: "KLPRCI_TaskState" - Task execution state changed. See "task_new_state" attribute. "KLEVP_GroupTaskSyncState" - Task synchronization state changed. See "task_new_state" attribute. "GNRL_EV_VIRUS_FOUND" - Threat found. See also Parameters GNRL_EA_PARAM_* for some events for the list of general (cross-products) events.
"KLEVP_EVENT_GNRL_TYPES_ARRAY"	Array of (paramString)	List of the event types names, similar to "KLEVP_EVENT_TYPE". Optional.
"KLEVP_EVENT_GNRL_TYPE"	paramString	Interesting general event type (not task state change event), to be used when "EVP_INCL_GNRL_EVENTS" = true. Optional.
"KLEVP_EVENT_TSK_STATE_TYPE"	paramString	Interesting task state change event type ("KLPRCI_TaskState" or "KLEVP_GroupTaskSyncState"), to be used when "EVP_INCL_TASK_STATES" = true. Optional.
"task_new_state"	paramInt	Task state (for events of type "KLPRCI_TaskState"), to be used when "EVP_INCL_TASK_STATES" = true. Optional. The following values are possible: Group task state enum.
"EVP_LAST_EVENTS_ONLY"	paramBool	Include only the last task states, instead of all events on task states changes. Don't use with "EVP_INCL_GNRL_EVENTS" = true. Optional. False by default.
"KLEVP_EVENT_RISE_TIME_LEAST"	paramDateTime	Earliest time when the event was published, in UTC.
"KLEVP_EVENT_RISE_TIME_GREATEST"	paramDateTime	Latest time when the event was published, in UTC.
"KLEVP_EVENT_RISE_TIME_LAST_DAYS"	paramInt	Maximum period since the event was published until the moment of the event search, in days.
"KLEVP_EVENT_HOST_IP_FROM"	paramInt	Start of the IPv4 diapason.
"KLEVP_EVENT_HOST_TO"	paramInt	End of the IPv4 diapason.

"KLEVP_RFC2254_FILTER"	paramString	Additional general RFC2254-like filter string (see Search filter syntax) which can be constructed using supported event attributes. see List of event attributes for attribute names. For example, to find events from a virtual server with ID 7, having identity more than 1234567, with severity "Error" (3) or "Critical" (4), and type "GNRL_EV_VIRUS_FOUND" or "KLPRCI_TaskState": "(&(KLVSRV_ID=7)(event_db_id>1234567)(\|(GNRL_EA_SEVERITY=3)(GNRL_EA_SEVERITY=4)(\|(event_type="GNRL_EV_VIRUS_FOUND")(event_type="KLPRCI_TaskState"))))"
"EVP_FTX_QUERY"	paramString	Full-text search condition. See Full-text attribute.
"EVP_MAX_EVENTS_COUNT"	paramInt	Result set must not contain more that specified number of event records.
"EVP_MAX_EVENTS_SRCH_AREA"	paramInt	Search will be from last N events. Optional.
"EVP_INCLUDE_VS"	paramBool	Include data from virtual servers. Optional. True by default.
