There are several log monitoring options available on the internet and sadly, most of them require some type of work. Your log monitoring endeavor can be significantly simplified if the log file you wish to monitor actually has date and timestamps in it...meaning, do the lines in the log contain some type of date and time?

if so, then,

1. you can either write your own log monitoring script: this would take a lot of time and can be very messy. There are several scenarios to consider to ensure you are actually informed when the state of the log file and its contents changes or matches your specified criteria.

2. you can grab programs off the internet that will attempt to monitor the log for you. the drawback to this (in my opinion) is that most of these programs require the installation of other applications or they require too much time to get accustom to. but if you need their names, here they are: swatch, splunk.

3. i have nagios installed in my environment and i use a tool called logrobot. you can do a search for logrobot and see if that fits your need. as far as i know, it doesn't send emails..except only via Nagios. but i guess it can be configured to do so via cron if thats what you needed.

if you dont have timestamps in your log file, things can get very messy and i would leave this to other members of this forum to provide their suggestions for this type of situation.

If you have Nagios, you may want to read this article:

modemmanager

MODEMMANAGER(8) 					      System Manager's Manual						   MODEMMANAGER(8)

NAME

       ModemManager - modem management daemon

SYNOPSIS

       ModemManager [--version] | [--help]

       ModemManager [--debug] [--log-level=<level>] [--log-file=<filename>] [--timestamps] [--relative-timestamps]

DESCRIPTION

       The  ModemManager  daemon  provides a unified high level API for communicating with (mobile broadband) modems. While the basic commands are
       standardized, the more advanced operations (like signal quality monitoring while connected) varies a lot.

       ModemManager is a system daemon and is not meant to be used directly from the
	      command line.

OPTIONS

       The following options are supported:

       --version
	      Print the ModemManager software version and exit.

       --help Print ModemManager's available options and exit.

       --debug
	      Runs ModemManager with "DEBUG" log level and without daemonizing. This is useful for debugging, as it directs log output to the con-
	      trolling terminal in addition to syslog.

       --log-level=<level>
	      Sets  how much information ModemManager sends to the log destination (usually syslog's "daemon" facility). By default, only informa-
	      tional, warning, and error messages are logged. Given level must be one of "ERR", "WARN", "INFO" or "DEBUG".

       --log-file=<filename>
	      Specify location of the file where ModemManager will dump its log messages, instead of syslog.

       --timestamps
	      Include absolute timestamps in the log output.

       --relative-timestamps
	      Include timestamps, relative to the start time of the daemon, in the log output.

       SEE ALSO
	      NetworkManager(8).
