If you have selected to store billing messages to the database,
it is also possible to generate and display a set of histograms
from the data in these tables. To turn on plot generation, set
the property httpd.enable.plots.billing
to
true
and restart the domain in which the
httpd
is running.
Example:
Extract from the layout file:
[httpdDomain] billing.enable.db=true httpd.enable.plots.billing=true [httpdDomain/httpd] [httpdDomain/billing] ...
The the frequency of plot refreshing and the type of plot produced can be controlled by:
billingPlotsTimeoutInMins
(defaults to30
)httpd.plots.billing.type
(defaults topng
and can be set togif
)
The plots provide aggregate views of the data for 24-hour, 7-day, 30-day and 365-day periods.
The plot types are:
(Giga)bytes read and written for both dCache and HSM backend (if any)
Number of transactions/transfers for both dCache and HSM backend (if any)
Maximum, minimum and average connection time
Cache hits and misses
Note
The data for this last histogram is not automatically sent, since it contributes significantly to message traffic between the pool manager and the billing service. To store this data (and thus generate the relevant plots), the
poolmanager.enable.cache-hit-message
property must be set either indcache.conf
or in the layout file for the domain where thepoolmanager
runs:poolmanager.enable.cache-hit-message=true
Each individual plot can be magnified by clicking on it.
