checking a counter on a website

[Matthew Joyce]

Perhaps store the data in a database with a timestamp.
 
When the next check is done
    Retrieve the last entry from the database
    Store the new data
    Calculate the delta or average
    Check the age of the delta
    Compare against your threshold
    Return a status
 
Python, Perl, even PHP (cmd) can give you easy access to the db.
 
Or bash : http://www.edlsystems.com/shellsql/

	This actually hits on what I consider to be one of Nagios'
(few) weaknesses.  A lot of time, when I do my checks, I'm not nearly as
interested in the value of a check as in the change in the value since
the last check.  This is a good example.  Another item I monitor is
changes in the SNMP Interface error counters.  For example, if I get
more than 5 errors/second, I need to send out an alert.  Finally, I have
the same issue monitoring SNMP Interface statuses.  But, Nagios has no
feature to remember data between invocations of the checks.  So, I end
up storing this data in temporary files. If there was a facility to
provide some information back to Nagios, and retrieve it on the next
one, that would be wonderful.

	I would just write a quick script that grabs the value on the
counter, then grabs the value again and subtracts the first from the
second.  Publish that value out via SNMP and then just use check_snmp to
verify that the value is >=1.  People with more programming skills than
I would probably just write one plugin to do it all.

	Anyone ever tried to check a websites hit counter and return a
warning if the hit counter has not incremented since the previous check?
