mod_measure_modules: Report module statuses via OpenMetrics Someone in the chat asked about a health check endpoint, which reminded me of mod_http_status, which provides access to module statuses with full details. After that, this idea came about, which seems natural. As noted in the README, it could be used to monitor that critical modules are in fact loaded correctly. As more modules use the status API, the more useful this module and mod_http_status becomes.

    Warn admins about outgoing s2s connections that are refused due to
    invalid or untrusted certificates
...

Introduction
============

Similar to mod\_watchregistrations, this module warns admins when an s2s
connection fails due for encryption or trust reasons.

The certificate shows the SHA1 hash, so it can easily be used together
with mod\_s2s\_auth\_fingerprint.

Configuration
=============

    modules_enabled = {
        -- other modules --
        "watchuntrusted",

    }

    untrusted_fail_watchers = { "admin@example.lit" }
    untrusted_fail_notification = "Establishing a secure connection from $from_host to $to_host failed. Certificate hash: $sha1. $errors"

  Option                          Default                                                                                                         Description
  ------------------------------- --------------------------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------
  untrusted\_fail\_watchers       All admins                                                                                                      The users to send the message to
  untrusted\_fail\_notification   "Establishing a secure connection from \$from\_host to \$to\_host failed. Certificate hash: \$sha1. \$errors"   The message to send, \$from\_host, \$to\_host, \$sha1 and \$errors are replaced
  untrusted\_message\_type        `"chat"`                                                                                                        Which kind of message to send. `"normal"` or `"headline"` are other sensible options
  untrusted\_ignore\_domains      Empty                                                                                                           The domains that this module should not warn about
