- indexes already exist):
- 
- CREATE UNIQUE INDEX history_log_2 on history_log (itemid,id);
- CREATE UNIQUE INDEX history_text_2 on history_text (itemid,id);
- CREATE INDEX graphs_items_1 on graphs_items (itemid);
- CREATE INDEX graphs_items_2 on graphs_items (graphid);
- CREATE INDEX services_1 on services (triggerid); - Start agent after and shut down before proxy and server by default.
