availability-report

Usage:

Can't locate RRDs.pm in @INC (@INC contains: . /usr/lib/remstats/lib /usr/lib/perl5/ /usr/local/lib/perl/5.6.1 /usr/local/share/perl/5.6.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.6.1 /usr/share/perl/5.6.1 /usr/local/lib/site_perl) at ../availability-report line 31.
BEGIN failed--compilation aborted at ../availability-report line 31.

Description:

This is mainly intended to be called from availability-report.cgi. It provided a report on "availability" of specified RRD variables, by default, all that have definitions in the availability config-file. Exactly what it means for a variable to be "available" is up to you. It's intended to give some measure of when a host or service isn't useable, so, e.g. the default definition of availability for the ping RRD variable rcvd (number of ping responses received) is:

	ping rcvd MINIMUM > 0

In english, the rcvd variable is considered unavailable if:

	- it is less than or equal to zero (I.E. it didn't respond to ping)
	- there is no data available for that time period

N.B.: The interaction between rrd archive consolidation and the xff value, (see rrdcreate), can result in longer periods of unavailability or conversely, masking periods of unavailability. Choose the consolidation function carefully to make sure you're getting the best data possible.
