sudo sh start-dev.sh

ERROR: OTP release R14B04 does not match required regex R17
make: *** [app] Error 1
Erlang R14B04 (erts-5.8.5) [source] [64-bit] [smp:8:8] [rq:8] [async-threads:0] [kernel-poll:false]

is this an issue? how to fix it?

The ideal use of bigwig would be over a cluster with bigwig reporting from its own node about other nodes attached to it, each running a daemon application built specifically to report to the master bigwig node. This way we don't have to care about the cowboy or jsx versions and bigwig still monitors all of our nodes.

Erlang R15B has been released.
Should this line in rebar.config:
{require_otp_vsn, "R14"}
be changed to:
{require_otp_vsn, "R15B"}?

Unfortunately, for Spawnfest, a 'hacked' version of jsx was suitable. Other installations may have applications which depend on and load the jsx module, causing issues. We need to wrap our calls to jsx with code that transforms the Erlang terms before they become JSON.

The README said that you can run bigwin as a hidden node and monitor other nodes. Could you please provide some description of how to do it. I can't figure out how it works.

Been reading Joe's book again and I've noted the following apps that could be worth replacing by bigwig:

• tv (ets/mnesia)
• erlang:trace / dbg:tracer (trace processes in one click), would be nice along a live sys:get_status

when i open brower,there is a error:

DataTables warning (table id = 'etop_table'): Requested unknown parameter '0' from the data source for row 0.

please help.

This happens often when a node is selected that no longer exists after an update arrives (e.g. if a process is killed).

Hi,

Is there any example that shows I cna monitor remote erlang app??? I would like to monitor and collect stats on remote erlang node withotu installing anything on the target node.

whne I trie the -hiddnen node method, it crashed.

Thanks

hi mokele, I'm use latest version bigwig. But I have a question.

Erlang R15B01 (erts-5.9.1) [source] [64-bit] [smp:4:4] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.9.1 (abort with ^G)
(bigwig@ubuntu)1> bigwig:start().
{error,{not_started,jsx}}

I need your help, thanks.

In https://github.com/hyperthunk/nodewatch, which is a bit stalled at the moment as I'm too busy to work on it, I used the eper project to do the stats collecting. That has numerous advantages, including the fact that it'll put a proxy between you and the production nodes, so that the monitoring app (vm) doesn't have to be on the same subnet or use the same cookie.

Anyways, https://github.com/massemanet/eper supports lots of additional vm stats (system, network) and it would be nice these could creep into bigwig. Also, being able to publish to bigwig somehow, things like custom performance counters and the like, would be very nice.

I am not able get dependencies, there is some problem with cowlib.

bigwig/deps/cowlib failed application validation with reason:
{missing_app_file,"bigwig/deps/cowlib"}.

I already tried to change versions for cowboy but it does not help. Maybe you know what is wrong here.

Thanks.

Is there any chance you could add a license to this?

PS: MIT or BSD would be awesome!

Does bigwig support multiple nodes monitoring simultaneously and notify when some node is down or disconnected?
