I need some help analyzing the attached metrics. System context is 2 LPAR's in a P795 running WebSphere App Server across 4 nodes (2 on each LPAR).
Over the weekend both LPAR's lost power and upon re-start the application server response times have degraded by 25-30% for no obvious reasons.
Our middleware guys tell me that the LPAR's recovered OK and are running fine. However from an application response time perspective this is clearly not the case.
I have attached 2 text files capturing a bunch of metrics during the peak period and would be really interested in your expert thoughts.
can some tell me how to do this. I mean, i tried finding this out on my own but when I checked the man pages, i got a truckload of commands available pertaining to this task which in turn got me confused.
so my question is, if there is a simple straight forward(not necessarily easy) way to... (2 Replies)
Hi,
Does anyone know of any programs that can create Unix (Solaris) server metrics such as server uptime, services uptime, processor utilization by hour by day, memory utilization by hour by day, active users by hour by day, etc?
Thanks! (2 Replies)
What do others use for measuring I/O statistics? I'd like something versatile, as in being able to watch (like iostat, but easier to trend), generate load (like iozone, but more realistic), and perform somewhat generalized benchmarks (like bonnie, but more current.) It would scale from a few... (0 Replies)

plack::middleware::lint
Plack::Middleware::Lint(3pm) User Contributed Perl Documentation Plack::Middleware::Lint(3pm)NAME
Plack::Middleware::Lint - Validate request and response
SYNOPSIS
use Plack::Middleware::Lint;
my $app = sub { ... }; # your app or middleware
$app = Plack::Middleware::Lint->wrap($app);
# Or from plackup
plackup -e 'enable "Lint"' myapp.psgi
DESCRIPTION
Plack::Middleware::Lint is a middleware component to validate request and response environment formats. You are strongly suggested to use
this middleware when you develop a new framework adapter or a new PSGI web server that implements the PSGI interface.
This middleware is enabled by default when you run plackup or other launcher tools with the default environment development value.
DEBUGGING
Because of how this middleware works, it may not be easy to debug Lint errors when you encounter one, unless you're writing a PSGI web
server or a framework.
For example, when you're an application developer (user of some framework) and see errors like:
Body should be an array ref or filehandle at lib/Plack/Middleware/Lint.pm line XXXX
there's no clue about which line of your application produces that error.
We're aware of the issue, and have a plan to spit out more helpful errors to diagnose the issue. But until then, currently there are some
workarounds to make this easier. For now, the easiest one would be to enable Plack::Middleware::REPL outside of the Lint middleware, like:
plackup -e 'enable "REPL"; enable "Lint"' app.psgi
so that the Lint errors are caught by the REPL shell, where you can inspect all the variables in the response.
