=Introduction=

Czartool is a collection of Perl scripts designed to assist when monitoring the IPP system. Czartool began as a simple script to quickly display the current status of each label in the system, i.e. how many images pending, how many faults. A webpage followed on ippMonitor, then a database was implemented in combination with a polling program (czarpoll) which updates the database every few minutes with the current status of the IPP.

= User notes =

Most users will use czartool via the web page in ippMonitor. This gives a snapshot of processing at the current time, with plots starting from around 6:30am in the morning, since this is when (currently) burntool is scheduled to begin processing the previous night's data.

There are, however, other useful Perl scripts available in {{{trunk/tools}}} that enable the user to go back further in time and create plots or metrics of particular labels, stages or date ranges. The main tool of interest is czarplot.

All times are in HST. When necessary (i.e. when query rawExp in gpc1, HST is converted to UTC internally).

== Metrics ==

Since czartool has a database containing a history of IPP processing since July, it is therefore useful for deriving metrics.
