Simulate a cluster's response to events.

This high-level function essentially implements crm_simulate(8). It operates on an input CIB file and various lists of events that can be simulated. It optionally writes out a variety of artifacts to show the results of the simulation. Output can be modified with various flags.

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in,out]	scheduler	Scheduler data
[in]	injections	A structure containing cluster events (node up/down, tickets, injected operations)
[in]	flags	A bitfield of :pcmk_sim_flags to modify operation of the simulation
[in]	section_opts	Which portions of the cluster status output should be displayed?
[in]	use_date	Date to set the cluster's time to (may be NULL)
[in]	input_file	The source CIB file, which may be overwritten by this function (may be NULL)
[in]	graph_file	Where to write the XML-formatted transition graph (may be NULL, in which case no file will be written)
[in]	dot_file	Where to write the dot(1) formatted transition graph (may be NULL, in which case no file will be written)

Returns

Standard Pacemaker return code
