Watchdog Statistics Gone!

[DavidCollom]

I just recently noticed that my watchdog graph statistics have just stopped working. i have some bar graph of the first day but nothing else.
Here is my Watchdog Crontabs:

0 1 * * 1 /usr/local/psa/libexec/modules/watchdog/cp/secur-check
0 1 * * 1 /usr/local/psa/libexec/modules/watchdog/cp/send-report weekly
10 1 * * * /usr/local/psa/libexec/modules/watchdog/cp/clean-sysstats
15 1 * * * /usr/local/psa/libexec/modules/watchdog/cp/pack-sysstats day
15 1 * * 1 /usr/local/psa/libexec/modules/watchdog/cp/pack-sysstats week
15 1 1 * * /usr/local/psa/libexec/modules/watchdog/cp/pack-sysstats month
15 1 1 * * /usr/local/psa/libexec/modules/watchdog/cp/pack-sysstats year
20 1 * * * /usr/local/psa/libexec/modules/watchdog/cp/clean-events
0 3 * * 7 /usr/local/psa/libexec/modules/watchdog/cp/clean-reports

Not sure if one's missing but my graph on statistics page stops about 3 days ago. is their a log file or anything anywhere i can check?
