diff() = [recon:proc_attrs() | recon:inet_attrs()]
| count/1 | Takes a list of terms, and counts how often each of them appears in the list. |
| inet_attrs/1 | Returns the attributes (recon:inet_attrs()) of
all inet ports (UDP, SCTP, TCP) of the node. |
| inet_attrs/2 | Returns the attributes required for a given inet port (UDP, SCTP, TCP). |
| port_list/1 | Returns a list of all the open ports in the VM, coupled with
one of the properties desired from erlang:port_info/1-2. |
| port_list/2 | Returns a list of all the open ports in the VM, but only
if the Attr's resulting value matches Val. |
| proc_attrs/1 | Returns the attributes (recon:proc_attrs()) of
all processes of the node, except the caller. |
| proc_attrs/2 | Returns the attributes of a given process. |
| sample/2 | Runs a fun once, waits Ms, runs the fun again,
and returns both results. |
| scheduler_usage_diff/2 | Diffs two runs of erlang:statistics(scheduler_wall_time) and returns usage metrics in terms of cores and 0..1 percentages. |
| sliding_window/2 | Compare two samples and return a list based on some key. |

| term_to_pid/1 | Transforms a given term to a pid. |
| term_to_port/1 | Transforms a given term to a port. |
| time_fold/6 | Calls a given function every Interval milliseconds and supports
a fold-like interface (each result is modified and accumulated). |

count(Terms::[term()]) -> [{term(), Count::integer()}]
Takes a list of terms, and counts how often each of them appears in the list. The list returned is in no particular order.
inet_attrs(AttrName::term()) -> [recon:inet_attrs()]
Returns the attributes (recon:inet_attrs()) of
all inet ports (UDP, SCTP, TCP) of the node.
inet_attrs(AttributeName, Port::port()) -> {ok, recon:inet_attrs()} | {error, term()}
Returns the attributes required for a given inet port (UDP, SCTP, TCP). This form of attributes is standard for most comparison functions for processes in recon.
port_list(Attr::atom()) -> [{port(), term()}]
Returns a list of all the open ports in the VM, coupled with
one of the properties desired from erlang:port_info/1-2.
port_list(Attr::atom(), Val::term()) -> [port()]
Returns a list of all the open ports in the VM, but only
if the Attr's resulting value matches Val. Attr must be
a property accepted by erlang:port_info/2.
proc_attrs(AttrName::term()) -> [recon:proc_attrs()]
Returns the attributes (recon:proc_attrs()) of
all processes of the node, except the caller.
proc_attrs(AttrName::term(), Pid::pid()) -> {ok, recon:proc_attrs()} | {error, term()}
Returns the attributes of a given process. This form of attributes is standard for most comparison functions for processes in recon.
A special attribute isbinary_memory, which will reduce the memory used
by the process for binary data on the global heap.
sample(Ms::non_neg_integer(), Fun::fun(() -> term())) -> {First::term(), Second::term()}
Runs a fun once, waits Ms, runs the fun again,
and returns both results.
scheduler_usage_diff(SchedTime, SchedTime) -> undefined | [{SchedulerId, Usage}]
Diffs two runs of erlang:statistics(scheduler_wall_time) and returns usage metrics in terms of cores and 0..1 percentages.
Compare two samples and return a list based on some key. The type mentioned
for the structure is diff() ({Key,Val,Other}), which is compatible with
the recon:proc_attrs() type.
sublist_top_n_attrs(List::[Attrs], Len::pos_integer()) -> [Attrs]
Returns the top n element of a list of process or inet attributes
term_to_pid(Pid::recon:pid_term()) -> pid()
Transforms a given term to a pid.
term_to_port(Port::recon:port_term()) -> port()
Transforms a given term to a port
time_fold(N, Interval, Fun, State, FoldFun, Init) -> [term()]
Calls a given function every Interval milliseconds and supports
a fold-like interface (each result is modified and accumulated)
time_map(N, Interval, Fun, State, MapFun) -> [term()]
Calls a given function every Interval milliseconds and supports
a map-like interface (each result is modified and returned)
triple_to_pid(N, N, N) -> pid()
Equivalent of pid(X,Y,Z) in the Erlang shell.
