let watchdog send mail to webmaster with data of active requests

pool_remap_watchdog: new watchdog for potentially stuck processes

This watchdog checks every minute the running jobs and maps very slow

requests to the slow pool (if configured) to avoid that the

default pool is getting filled up with more stuck requests.

This ensures the livelyness of a server.

reduce verbosity

Fix typo

Update proctoring upload URL to the new one

send also HEAD requests to the request monitor

fix filtering logic

prefer "ns_conn isconnected" over "ad_conn isconnected", since the latter might not notice changes in the connect state

  1. … 18 more files in changeset.
avoid double loading of bootstrap

added pool to long-calls statistics (requires at least NaviServer 4.99.5, May 2013)

use "ad_file" as a means to avoid unexpected tilde substitution in file names

improve spelling: move closer to the linux documentation recommendations

  1. … 34 more files in changeset.
fix typos

add more query details to logged query

add entries to longcalls as well when filtertime > 1s, or queuetime > 0.5s

make on/off logic less confusing

make monitor URLs easier configurable

don't use request-blocking on embedded items

improve performance of perDayCleanup significantly by not persisting Users.hits

remove all of /shared from request blocking

make blocked request easily detectable in monitoring tools like elasticsearch by using 429 as HTTP result code

added connection pool management

TODO: improved parmeterization

fix variable name (many thanks to Franz Penz)

whitespace cleanup

add support for deleted users, handle this case centrally

Try to avoid double-counting in request statistics, when a user logs

in. Previously, when a user logs in, the user was counted once as

un-authenticated user, and once as authenticated one.

TODO: when this works sufficiently well, the same should be done

as well for the 24h statistics.

- provide compatibility with Highcharts v8

- remove dependency on jquery

Highcharts: specify latest stable 7 as the version we support, as default is as today 8.0.1 , which is not compatible with current code

reduce string operations slightly

- set sanitize on logfile writer per default to 0

- change cleanup interval from 1h to 71min, since on the hour interval, there are already many things going on in OpenACS
