Session Event Triggers allow you to alert people and external systems to events that occur inside this system. The Event Filter syntax is very similar to the SQL "where" clause syntax. Properties, operators, literals, variables, and functions can be combined to create powerful expressions. The same properties can be used inside your actions to display information to users or provide information to external systems.

Available objects/properties

`OldSession.*`	Session properties prior to any alterations made by the trigger event (available properties are the same as those of Session listed below)

`Connection.ClientType`	The client type (`'Unknown'`, `'DotNetWinForms'`, `'JavaSwing'`, `'JavaAndroid'`, `'MonoTouchIos'`) of the connection as a string
`Connection.ClientVersion`	The client version of the connection
`Connection.Attributes`	The attributes of the connection, currently unused
`Connection.NetworkAddress`	The network address of the connection, usually in `N.N.N.N` IPv4 notation
`Connection.ParticipantName`	The participant name of the connection
`Connection.ConnectedTime`	The date/time connected of the connection
`Event.EventID`	The unique ID of the event in GUID (Globally Unique Identifier) format
`Event.Host`	The host that performed the event, if it was performed outside of a connection
`Event.EventType`	The type of the event as a string; values are listed below
`Event.Time`	The date/time of the event
`Event.Data`	Data that describes the event

Filter operators

`AND`	Combines two expressions and matches if they are both true
`OR`	Combines two expressions and matches if one or both is true
`NOT`	Negates an expression or operator
`=`	Determines whether two values are equal
`<>`	Determines whether two values are not equal
`<`	Determines whether one value is less than another value
`>`	Determines whether one value is greater than another value
`<=`	Determines whether one value is less than or equal to another value
`>=`	Determines whether one value is greater than or equal to another value
`IN`	Used to see if a property is in a set of values
`LIKE`	Used to compare strings, usually with wildcards (`*` and `%` are both valid)
`+`	Add two values together
`-`	Subtract one value from another
`*`	Multiply two values together
`/`	Divide one value by another
`%`	Mod one value by another

Filter functions

`LEN(expression)`	Return the length of a string
`IIF(expression, trueResult, falseResult)`	Return one of two values depending on whether the expression is true or false
`ISNULL(expression, resultIfNull)`	Return the value of the expression or another value if the expression returns null
`TRIM(expression)`	Trim whitespace from the beginning and end of a string
`SUBSTRING(expression, start, length)`	Get part of a string
`CONVERT(expression, type)`	Explicitly convert between datatypes

Filter literals

Strings	Quoted with single quote character (`'`); escape single quotes inside the string with two consecutive single quotes
Numbers	All numbers can be used without quoting or any other special notation
Dates/Times	Quoted with single quote character (`'`) or number sign (`#`)
Booleans	Use "`true`" or "`false`", unquoted

Emitting data in actions

Output is formatted with {DataSpecifier:FormatSpecifier} curly brace notation. This can be used in most action fields to customize behavior.

Data specifiers:

Specifying '*' will select all objects with their properties in a hierarchy.
Specifying 'Session' will select the session object with it's properties.
Specifying 'Connection' will select the connection object with it's properties.
Specifying 'Event' will select the event object with it's properties.
Specifying, as an example, 'Session.Name' will just select the value of the session name property.

Format specifiers:

Specifying 'json' (or 'j' for short) will emit the selected data in JSON format.
Specifying 'jsnq' (or 'q' for short) will emit the selected data in JSON format, but without surrounding double quotes for strings, allowing the data to be concatenated inside an outer JSON string.
Specifying 'xml' (or 'x' for short) will emit the selected data in XML format.
Specifying 'url' (or 'u' for short) will emit the selected data in URL format.
Specifying 'plain' (or 'p' for short) will emit the selected data in Plain format.
Omitting the format specifier will use the Plain format.

Examples:

{*:j} will emit all of the objects in a JSON hierarchy
{*:x} will emit all of the objects in a XML hierarchy
{Session.Name} will emit the session name
{Session:u} will emit all of the session properties in a URL-encoded string
{Session:u}&{Event:u} will emit all of the session and event properties in a URL-encoded string

Other usage notes

Parentheses can be used in filters for readability and to enforce operator precedence
Wildcards (* and %) can only be used in filters at the beginning or end of a LIKE expression, but not in the middle
No properties will ever be NULL, but rather empty strings
