proc_count/2Fetches a given attribute from all processes (except the caller) and returns the biggest Num consumers. Functions such as port_info/1 and port_info/2 are wrappers to provide more similar or more details than erlang:port_info/1-2, and, for inet ports, statistics and options for each socket. remote_load/2 remote_load(Nodes, Mod::module()) -> term() Nodes = [node(), ...] | node() Loads one or more modules remotely, in a diskless manner. get_state/1 get_state(PidTerm::pid_term()) -> term() Shorthand call to recon:get_state(PidTerm, 5000) get_state/2 get_state(PidTerm::pid_term(), Ms::non_neg_integer() | infinity) -> term() Fetch the internal state of an OTP process.

The values to be used can be the number of octets (bytes) sent, received, or both (send_oct, recv_oct, oct, respectively), or the number of packets sent, received, or both (send_cnt, recv_cnt, There are 3 of them: node_stats_print/2, which displays them, node_stats_list/2, which returns them in a list, and node_stats/4, which provides a fold-like interface for stats gathering. proc_window/3Fetches a given attribute from all processes (except the caller) and returns the biggest entries, over a sliding time window.

info/1Allows to be similar to erlang:process_info/1, but excludes fields such as the mailbox, which have a tendency to grow and be unsafe when called in production systems. RPC These are wrappers to make RPC work simpler with clusters of Erlang nodes. Erlang Start Os_mon I see only 100% usage one of the CPUs (the rest is 0%, but I'm using SMP). Erlang Memsup source/1 source(Module::module()) -> iolist() Obtain the source code of a module compiled with debug_info.

The function will gather statistics in two forms: Absolutes and Increments. Finally, the functions inet_count/2 and inet_window/3 provide the absolute or sliding window functionality of proc_count/2 and proc_count/3 to inet ports and connections currently on the node. 5. See config(4) for information about how to change the value of configuration parameters. When the system load is calculated with the percentage formula shown previously, the load will increase from 80% to 87%.

Allows to share code loaded locally with a remote node that doesn't have it rpc/1 rpc(Fun::fun(() -> term())) -> {[Success::term()], [Fail::term()]} Shorthand for rpc([node()|nodes()], Fun).

rpc/2Shorthand for rpc(Nodes, Fun, infinity). To practice a bit I dug up the good ole Fibanocci sequence. My solution was to disable storing results alltogether with CELERY_IGNORE_RESULT = True in the Celery config file to assure this does not happen again. The returned value divided by 256 produces the figure displayed by rup and top.

Snake Game in C# Digital Hardness of Integers Is the binomial theorem actually more efficient than just distributing Is it a security vulnerability if the addresses of university students are exposed? Functions to access node statistics, in a manner somewhat similar to what vmstats provides as a library. They have equivalents to erlang:process_info/2 in the functions info/2 and info/4, respectively. Choosing D = 50 means that 128 is 60% load, 256 is 80%, 512 is 90%, and so on.

info/3Equivalent to info() where A, B, and C are integers part of a pid. I rebuilt new server with Debian 7.5, rabbitmq 2.8.4, celery 3.1.13 (Cipater). remote_load/2Loads one or more modules remotely, in a diskless manner. main (N) -> fib (list_to_integer (atom_to_list (hd (N) ) ) ), halt (0).

It is not enough to just spread things into many processes, you actually have to make sure that these processes actually run concurrently. For about an hour or so everything worked beautifully again until celery started complaining again that it can't connect to rabbitmq!
