After the script getdata.pl is run from a trscrontab on pinger@pinger.slac.stanford.edu to gather data from the monitoring hosts, the data is inspected by checkdata_gif.pl for invalid data such as missing tokens, inability to send 10 packets etc. In addition a table is constructed showing the state (no response from the monitor, no data from monitor, partial data from the monitor, success) of gathering the data for each monitor node. Emails are sent to the administrator indicating which monitors were not successful. The typical follow up after a few days is to email the contact(s) at the monitor node to request help in fixing the problem.
