Request Monitoring for twebserver.
- twebserver (version 1.47.53 and above)

# It installs to /usr/local/lib
# To install elsewhere, change the prefix
# e.g. make install PREFIX=/path/to/install
make installWe split configuration in two parts: main and middleware.
The main part is needed for some stores and loggers
to be initialized in the main thread.
For example, if you are using the memstore store or the console logger,
they create the worker thread in the main thread and then pass it to the
middleware (twebserver) threads.
In main thread of your application:
package require treqmon
set middleware_config [::treqmon::init_main $main_config]In middleware threads of your application:
package require treqmon
::treqmon::init_middleware $middleware_config
::twebserver::add_middleware \
-enter_proc ::treqmon::middleware::enter \
-leave_proc ::treqmon::middleware::leave \
$routerThe following are supported configuration options:
- store - The store to use and its configuration. For example:
valkeystore {
host localhost
port 6379
}- logger - The logger to use and its configuration. For example:
logger {
console {
threshold 100
}
logfile {
threshold 100
path /var/log/treqmon.log
}
}where threshold is the number of events that have to be exceeded before the logger logs the events in bulk.
The following are supported thtml components:
- page_views_per_hour_chart.thtml
- page_views_per_minute_chart.thtml
- page_views_per_second_chart.thtml
- response_times_per_hour_chart.thtml
- response_times_per_minute_chart.thtml
- response_times_per_second_chart.thtml
- active_users_per_hour_chart.thtml
- active_users_per_minute_chart.thtml
- active_users_per_second_chart.thtml
- stats.thtml
- summary.thtml
You can import them in your application after you install thtml, chart.js, and purecss like this:
<import name="Stats" src="@treqmon/stats.thtml" />
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
