Dear Folks, I am writing with mainly a rant about Graphing and Reporting.
<Mainly OT rant> 1 About graphing with Nagios Why would one bother when 1.1 Cacti does such a good job 1.2 Nagios could check the Cacti RRDs with either check_rrd, or by an outboard (Cron scheduled) RRD poller that submits passive service check results 1.3 the graphs can be associated with Nag service checks by either - explict URL of the Cacti graph in the service check output - for the adventurous, a Wiki front end that displays some of the Nag CGI service status and a link to the Cacti graph. As a footnote, since Cacti supports RRD 1.2 with built-in supported Holt Winters forecasting RRAs, the poller could be smart and simply check the exception Data store to see if the current rate is in fact outside the normal seasonal variation (computed by the Holt Winters algorithm inside the RRD). Of course this would require the modification of the RRDs that Cacti produces to add the HW RRAs (this doesn't require that the RRD content be unloaded and reloaded IIRC). 2 About reporting After writing a lot of code in Nagios::Report to extract and report on Nagios availability data it occurs to me that a better way of doing Reporting is to 2.1 put the availability data in a DB table (prob with an auto-incremented index) 2.2 use either 2.2.1 ad-hoc SQL queries, or 2.2.2 the reporting package of your choice (eg iReport) I hope that Nagios::Report will be enhance to take advantage of DBD::Ram, a Perl module that very easily gets a CSV file with LWP and sticks it in an in core DB that can almost as easily be used as a Data source to insert rows into the DB of your choice (MySQL, or whatever). </Mainly OT rant> and now back to our normal program. Yours sincerely. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
