There are mistakes in web monitoring documentation for Zabbix Server 2.4:
https://www.zabbix.com/documentation/2.4/manual/web_monitoring/items

• I can't find such syntax for "not equal" trigger expressions in zabbix 2.4 docs:

  {host:web.test.fail[Scenario].last()}#0
  

  As I understand new syntax is:

  <>

• It doesn't clear, that in:

  web.test.time[Scenario,Step]
  

  item, we need to specify some third argument, otherwise Zabbix say about wrong item key.
  ?lso it's not clear, what does this argument means.
  In my case, I specified "resp" as third argument(find in the internet).

Please, fix and complete docs.
