logrtitems from 2.0.11 to 2.0.12:
logrtitem becomes NOTSUPPORTED if a directory where the log files are expected to be found does not exist (this is mentioned for clarification, there is no change from 2.0.11 to 2.0.12).
logrtitem does not make it NOTSUPPORTED (on 2.0.11 it caused NOTSUPPORTED).
logrtitem are logged as warnings into Zabbix agent log file but do not make the item NOTSUPPORTED (on 2.0.11 it caused NOTSUPPORTED).
logrtitem became NOTSUPPORTED. Zabbix can monitor its agent log file except when DebugLevel=4.
logrtitem checks has been improved the limits on maximum number of log file records analysed and number of matching records sent to server in one check are not modified. For example, if a
logrtitem has Update interval of 1 second, by default the agent will not analyse more than 400 log file records and will not send more than 100 matching records to Zabbix server in one check. By increasing MaxLinesPerSecond parameter in agent configuration file or setting maxlines parameter in the item key the limit can be increased up to 4000 analysed log file records and up to 1000 matching records sent to Zabbix server in one check. If the Update interval is set to 2 seconds the limits for one check would be set 2 times higher than for Update interval 1 second.
