2016-04-25Fix type spec for cpu_sup:util/1Péter Gömöri
The documentation correctly states that the Busy and NonBusy components in the return value of cpu_sup:util/1 are not tuples but list of tuples: "If the detailed option is given, this is a *list* of {State, Share} tuples"

2016-02-17Makefiles: Remove test_server from include path and code pathBjörn Gustavsson
Since no test suites includede test_server.hrl, there is no need to have test_server in the include path or code path.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.

Without this, cpu_sup.c won't compile on FreeBSD, as the name overlaps with the send() socket call.
2014-12-29os_mon: cpu_sup should use native sysctl/libkvm calls on BSDAlex Wilson
This avoids forking off with os:cmd every time we just want to collect the load averages. riak does this every second, which results in a lot of unnecessary load.

Some of the structs and functions needed by memsup.c are in vmmeter.h on OpenBSD, too.

2014-08-29Clarify error for slow `cpu_sup` port initLuca Favatella
I noticed that running an R16B03-1 node on an overloaded host produced log entries like the following ones: ``` 2014-08-22 21:52:31 =ERROR REPORT==== Error in process <0.24112.3> on node '[email protected]' with exit value: {{case_clause,{data,4711}},[{cpu_sup,get_uint32_measurement,2,[{file,"cpu_sup.erl"},{line,227}]},{cpu_sup,measurement_server_loop,1,[{file,"cpu_sup.erl"},{line,585}]}]} ``` ``` ===== ALIVE Fri Aug 22 21:50:14 CEST 2014 [os_mon] cpu supervisor port (cpu_sup): Erlang has closed [os_mon] cpu supervisor port (cpu_sup): Erlang has closed [os_mon] cpu supervisor port (cpu_sup): Erlang has closed [os_mon] cpu supervisor port (cpu_sup): Erlang has closed ===== ALIVE Fri Aug 22 22:07:46 CEST 2014 ``` I performed a code inspection on the `cpu_sup` module and I concluded that the `case_clause` error shows a small issue in the `cpu_sup` module, that happens when the port used in `cpu_sup` is slow to start - as it may happen on an overloaded node. The `cpu_sup` `gen_server` process keeps in its state the pid of an unlinked process (called "measurement server" - see `cpu_sup:init/1`), in order to do dirty stuff (e.g. reading the filesystem, running OS commands) and start_link-ing & managing the connected process to a port (called "port server" - see `measurement_server_init/0`). So the process organization looks like this: ``` cpu_sup - measurement server - port server - port ``` When the measurement server start_links the port server (see `port_server_start/0`) it sends a `{self(), ?ping}` message to it and expects an answer within 6s, otherwise it returns `{error, timeout}` rather than the pid. This has two issues: * The measurement server keeps `{error, ...}` in its state as if it were a pid - that makes no sense; * A late `{Pid, {data,4711}}` response may arrive in the mailbox of the measurement server, that will believe it to be a request to be processed, causing a `case_clause` error. This commit teaches the measurement server to check the success of the initialization of the port server by matching on the return value of `port_server_start/0` (renamed to `port_server_start_link/0` for the sake of clarity) in order to fail earlier and with an error clearer than `{case_clause,{data,4711}}`. In such case I expect the measurement server to be restarted by the `cpu_sup` `gen_server` (see `handle_call/3`) - as before. BTW It is not clear to me when the `handle_info({'EXIT', _Port, Reason}, State)` may be called (the `cpu_sup` `gen_server` does not link to the measurement server) but I am leaving it.

2014-07-01Add 'disksup_posix_only' parameter to disksupJohannes Weißl
On embedded (Linux) systems the "df" program is very often provided by the Busybox (or Toolbox) project. This version does not provide the "-l" option (for displaying only local filesystems) used in disksup.erl. To make disksup work on these embedded platforms, this patch adds a new application parameter 'disksup_posix_only', to make diskup use only options defined in the POSIX standard: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/df.html

2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.
