Cron Job Automated Email Alternatives?
Hi guys, not sure if this would be the right place for this but I dont where else it would go... I'm new to Unix too, so please bare with me 
I guess first up some background on the situation. We have some scripts that run as cron jobs which monitor and check the health, etc of our servers. They are configured to alert us (by sending emails to us) whenever they get an exception or appear to be critical or even go down.
This is all well and good, however at the moment we are having some issues and their stability has been more than rocky so they are sending A LOT of emails. I arrived this morning to 250 alerts in my inbox.
Now granted this is for about 8 different servers, but that's still alot of noise. We even get alerted that the server is down each time we manually bounce them. The team is at the point where they are basically ignoring all these emails which is not a good thing because when something really bad does actually happen, we'll miss it in the noise.
Now, my question is kind of two-fold. First up, is there a way we can make these scripts "smarter" so they only alert us when a certain threshold of errors is reached over a certain time period or something?
Secondly, rather than spam our inboxes with emails is there a method or solution to publish alerts to a webpage or a widget or something so only the person who is on support that particular day/week can log on and then be informed of the server activity (rather than all of us getting emails)?

git-sh-setup
GIT-SH-SETUP(1) Git Manual GIT-SH-SETUP(1) NAME
git-sh-setup - Common git shell script setup code SYNOPSIS
. "$(git --exec-path)/git-sh-setup" DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish scripts and/or are writing new ones. The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal git directories and a few helper shell functions. Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage() shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not). The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment. FUNCTIONS
die exit after emitting the supplied error message to the standard error stream. usage die with the usage message. set_reflog_action set the message that will be recorded to describe the end-user action in the reflog, when the script updates a ref. git_editor runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified and the terminal is dumb. is_bare_repository outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated working tree). cd_to_toplevel runs chdir to the toplevel of the working tree. require_work_tree checks if the repository is a bare repository, and dies if so. Used by scripts that require working tree (e.g. checkout). get_author_ident_from_commit outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
